The challenges of horticultural labour
Labour – it’s a topic that is always on our minds, no matter the season.
According to reports by the Canadian Agriculture Human Resources Council, worker shortages cost the greenhouse, nursery and floriculture sector around $103 million in 2017/2018. Compared to other segments of agriculture, this one “employs 15% of the agricultural workforce, making it the largest employer in Canada’s agriculture sector.” Forecasting to 2029, they expect as many as 29,900 unfilled jobs mainly due to a lack in domestic labour.
During this same period in 2017/2018, the field vegetable sector had trouble filling 1,500 jobs, costing $403 million to the industry and expecting 14,500 unfilled positions by 2029. The tree fruit and vine sector was no better, with 900 unfilled jobs and $94 million lost in sales, along with forecasts of 15,400 unfilled jobs by 2029.
Horticulture in general, whether indoor or outdoor seems to have a problem in attracting domestic talent.
This is why, back in September, we teamed up with sibling magazine, Fruit & Vegetable to hold a roundtable on horticultural labour. We invited six
Innovation Centre, Ont.
What came out of the roundtable was truly extraordinary. Panelists shared their perspectives as growers, educators and sector partners and some of the challenges they face when it comes to hiring, training and retaining staff. We asked panelists to discuss qualities that make up the ideal candidate and how education plays a part, and finally, discussed ways in which the sector can promote the opportunities that a career in horticulture can bring.
Altogether, the discussion was two hours long but every minute of it was gold. We edited it down to four parts, approximately 20 minutes each, but for those looking for the full experience – it’s available online.
I won’t divulge too much at this time, but suffice to say, horticultural education programs are more popular than ever, and it’s being driven by a love of food, plants and an interest in farm life. One of the problems is in rural life – how can we retain workers who want access to creature comforts or critical services nearby, such as good coffee and child care? Can the wages sustain a family?
In addition to the roundtable, there is a

Nature Fresh Farms inks massive lighting contract
Nature Fresh Farms has added 123 acres of lit production between themselves and their partners Ketler Farms, and VineFresh in both the U.S. and in Canada.
Signed with Netherlands-based company Agrolux Lighting, the deal is said to be one of the largest contracts for horticultural lighting in North America. The project involves a mix of HPS and LED, and it is slated for completion in the fall of 2022.
For Nature Fresh Farms, the lit crop will expand
across their Leamington, Ont., and Delta, Ohio farms. In Leamington, LED is planned for 31 acres of organic cucumbers. Ohio’s recently announced 45-acre expansion will also be devoted to LED-lit organics.
Currently, Nature Fresh Farms has 126 acres of lit production across its Delta and Leamington farms that were initially equipped with lighting in 2015 when they first began their partnership with Agrolux.

SETTLING SCORES AT THE SAWAYA GARDENS
In this second part of the Sawaya Garden Trials report, we look at high-scoring genera and representative varieties using the new points-based grading system.
BY MELHEM SAWAYA
In last month’s issue of Greenhouse Canada, part one of this article discussed how some products tend to look great at purchase time but do not last until mid-June. Meanwhile, other products do not look so great at purchase time, but improve rapidly when they are in the garden and will last till frost. Using examples from the Sawaya Garden Trials, I shared varieties that fit both scenarios.
In the last issue, I also shared some important reasons for staying informed about the different cultivars firsthand. In addition to differences in appearance at purchase time, some plants simply need a different sized container or a different retail time to show off their potential. In this second part of the Sawaya Garden Trials report, I will share information on the genera which customers usually gravitate towards. Of course, there are varieties in each genus that perform much better than others.
This year, I also introduced a points-based grading system. Varieties were scored based on the following characteristics with their weighting in brackets:
• General ease of maintenance (3)
• No need for deadheading (3)
• Heat tolerance(10)
• Cold tolerance (4)
• Rain tolerance (6)
• Wind tolerance (4)
• Draught tolerance (3)
• Flower recovery after the rain (10)
• Flower power (7)
• Disease and insect tolerance (5)
• Demand for fertilizer (2)
• 10-metre plant – I.e., Looks good only from 10 metres away or less (5)
• 10-to-100 metre plant – I.e., Looks just as great from 100 metres away as it does 10 metres away (10)
• Performance longevity (8)
These were the criteria on which I based the evaluation of each cultivar. If you think I missed some aspect that should be included in the evaluation, or if the grading should be adjusted, I will gladly look at suggestions.
For the simplicity of this article, the plants are scored as:
• Excellent (90-100)
• Very good (80-89)
• Good (70-79)
• Fair (50-69)
• Poor (below 50)
Before you start looking for the poorest scoring plants, I did not include any in this article. However, the breeders know it, and I am sure they are improving the variety or discarding it.
• Input cost – Price, number of plants per pot and required growing time (10)
• Customer appeal (10)
Here were some of the best scoring varieties, grouped by genus.
PETUNIA
As a genus, the petunia is the best for showcasing outdoors in the garden, especially ones that bounce back fast after the rain. That is why at the Miracle Gardens in Dubai, UAE, the only genus there is the petunia – with eight million of them on an eight-acre site. The plants are there from November till April, with little rain and warm-to-hot weather. Take a minute and Google ‘Miracle Gardens Dubai’ to see what I am talking about.
In Canada, we have hot weather and rain, and this year, there was lots of it. Some petunias bounce back in a matter of hours after the rain stops. Petunias are 10-to-100-metre plants – the highlights of our gardens. However, they would have been in much greater use if we could have better educated the consumer about these hungry plants. There are many poor varieties of petunias out there, so selecting good to excellent varieties is a step towards quality performing plants and successful customers. The following are a few varieties of petunias that scored from Good to Excellent – but this is not an exhaustive list.

Petunia Surfinia Purple Heart (2) is more vigorous than Heartbeat and has most of the qualities that place it in ‘Good’ standing.
Petunia hybrida Dekko Star Coral (3) and Petunia hybrida Dekko Lavender Eye (4) are from a very predictable trailing series of mediumsized flowers with ‘Very Good’ standing.
Petunia ColorRush Pink (5) and Petunia ColorRush Blue (6) are both trailing petunias with medium-to-large flowers. Both perform great either in combinations or on their own. In ‘Very Good’ standing.
Petunia Bee’s Knees (7) showed well throughout the whole summer, especially with its unique deep yellow colour and its cascading to trailing habit, joining those in ‘Very Good’ standing.
Petunia Supertunia Mini Vista
White (8) is a vigorous trailing petunia with flowers that are not affected by rain nor wind. The hotter it is, the more the flowers emerge to cover the entire plant. Joining it is Petunia Supertunia Vista Bubblegum (9), a larger flower variety with the type of performance that all breeders try to achieve. I would say with confidence that Bubblegum is the champion of all petunias. Both Vistas scored on the higher end of the ‘Excellent’ standing.
CALIBRACHOA
Calibrachoa is the most floriferous plant of all, flourishing in the heat when it is very sunny. It can also be grown cool and recovers from the rain fast. A 10-to100-metre plant, it makes any garden, patio, store front, driveway, or landscape look so much better. The ability to be highly floriferous comes from its branching power where fresh flowers are formed. At the same time, this also
explains the small-sized flowers. More branching means more flowers but usually smaller ones. Here are some representative varieties from the trials:
Calibrachoa Cha-Cha Frosty Lemon (10) is somewhat more vigorous but full, which makes it a great garden performer. ‘Very Good’ standing.
Calibrachoa Superbells Double Amber (11) is one member of the double-flowered Superbells series that gives this calibrachoa a more premium feel when it is marketed accordingly. It’s a hit in the garden and was in ‘Very Good’ standing.
Calibrachoa Hybrida Cabrio Yellow (12) is the rebel of the Cabrio series which is supposed to be compact – but not Cabrio Yellow. The whole series performed well in the trials and were in ‘Good’ standing overall.
COLEUS
Coleus is the most colourful of the leaf
plants. We could almost even call it a flower, and why not? We call poinsettias flowering plants because of their colourful bracts. Coleus is very popular with gardeners, especially now with the foliage craze, as well as the colours offered by different coleus varieties. If we exclude flower power from our score sheet, most of the coleus varieties on the market would be classified from Very Good to Excellent. They look great in landscape, gardens, and large containers from day one to frost. There are so many great varieties on the
market, and your choice comes down to your leaf colour preference or vigour. Here are a few varieties that reflected the different habits available; all good-lookers.
Coleus FlameThrower Sriracha (13) comes in a very hot colour with a medium growth habit that, like all coleus, can be grown in large pots or in gallons destined for landscapes wherever it is grown. It is a winner that received ‘Very Good’ standing.
Coleus Wasabi (14) is on the larger side and is great in landscape, but make sure the pots are placed in a heavy steel
or concrete container or else the wind will blow it away due to its enormous size. This is the same with many of the exceptionally large coleus, but in the landscape, they should be fine. In ‘Good’ standing.
Mixmasters Pico de Gallo (15) is a combination made up of members in the same coleus genus, which makes the combination more synergetic and colourful. In ‘Good’ standing.
Coleus Great Falls Iguazu (16) is one of the trailing coleuses that is not going

Coleus Main Street Bourbon Street (17) is a medium-growth coleus and very colourful. It is sturdy in the garden and works well in containers, landscape, and in some combinations. In ‘Very Good’ standing.
OSTEOSPERMUM
The current Osteospermum are no longer what they used to be. Breeders have done a great job in creating Osteospermum varieties that do not just tolerate the heat, but flourish in it. It is up to us to retrain the consumer to see these new features. Growing Osteospermum for early spring is expensive, but growing it for the regular spring season is great. By re-educating the consumer, we will no longer be stuck with Osteospermum because it will not be a cool-weather crop anymore. Here is evidence of some Osteospermum cultivars that did well throughout the summer.
Osteospermum Akila Sunset Shades (18) is a mix from seed that was very colourful all season long and looked great even with little deadheading. In ‘Good’ standing.
Osteospermum ecklonis
Tradewinds Lemon Zest (19) brought some bright yellow colour with flowers that never stopped, even during the very hot weather experienced this past summer. In ‘Good’ standing.
Osteospermum ecklonis Osticade Daybreak (20) showcased some very colourful shades of salmon and yellow, flowering through the whole summer as well. In ‘Good’ standing.
GERANIUM
Every year, we cover the Geranium genus in detail, so this year I am giving it a shorter review – and not because it is not important. On the contrary, the geranium is still one of the leading, if not the leading, bedding plants out there.
We know geranium flowers need deadheading after every rain, and if not, the botrytis-infected flowers will kill off the plants.
Geranium Zonal Dynamo Salmon
Improved (21) is one of the colours in my favourite series due to its medium vigour and flower power. Dynamo Salmon received ‘Good’ standing.
BEGONIA
The begonia is one of the largest genera among ornamental flowers and there are differing species between the fibrous, Boliviensis, Rieger, and Rex.
For a long time, there were only fibrous wax leaf begonias sold as the main bedding plant variety. Breeders were going after compact habits and early flowering, up to the point where the plants were almost flowering before the leaves emerged. Luckily, this trend is changing. We are now getting varieties that are robust with good flower
power, standing up to various weather conditions much better than any other species.
The Rieger begonia was always a popular indoor pot plant, but in the last 15 years, it has become a big garden performer.
The Boliviensis begonia is the newcomer and it is becoming popular in bedding plant applications due to large strides in new breeding.
There is enough to write an entire article on begonias, but for now, here are a few cultivars from our trials:
Begonia I’CONIA Miss Montreal (22) and Begonia I’CONIA Portofino Hot Orange (23) are two examples among a vast variety of Boliviensis begonias that
have excellent garden performance in full sun and can do well in semi-shade. They can get by with about four hours of sun each day, but to shine, they should receive over six hours a day. Little deadheading needed, they recover fast after a rain and produce mounds of colourful leaves that are covered with double blooms in spectacular colours. The key to a successful crop of Boliviensis begonias is to grow them in the greenhouse in full sun right from day one. Miss Montreal and Hot Orange were both in ‘Very good’ standing.
Begonia Megawatt Rose Bronze Leaf (24), Begonia x hybrida Viking Explorer Red on Green (25) and Begonia x hybrida Viking Red on Chocolate (26) are all examples of new
begonia breeding that puts vigour into the growth of wax begonias. These fibrous begonias are not only able to take cool, hot or very hot weather, but they offer some degree of drought recovery and remain in excellent condition after the rain. This entire species should be called a dream crop because it can be produced economically, has great greenhouse performance and delivers fantastic garden performance. Consumer success in growing the wax begonia on steroids is higher than average, which is why these varieties, the Big begonias and the Whoppers all received ‘Excellent’ standing.
GARDEN VEGETABLES

varieties available for our gardens. To cover them all, we would need more than one article, but here I could not resist sharing with you two varieties of basil that were outstanding in our trials. They were watered like each of the other three thousand varieties on-site.
Basil Everleaf Emerald Towers (27) gave us plenty of fresh basil leaves to last the whole summer along with lots to dry and save up for the winter – all with just one pot. To my surprise and excitement, there was no trace of downy mildew.
Basil Everleaf Thai Towers (28) had the same characteristics as Emerald Towers, but with added licorice-flavoured leaves that suit Thai cuisines.
If we had graded them, these two varieties of basil, in addition to Amazel Basil, would have received ‘Excellent’ standings.
OTHER EXCEPTIONAL CHOICES
Among the next eight varieties, some were old while others were new, but all displayed
exceptional garden performance.
Melampodium paludosum Showstar (29) is not a new variety, but it is one that is underused. Over the past four trials, Showstar has shown great performance. No deadheading, rain-proof, and loves the heat, the variety delivered a great look all through the season and was scored as ‘Very good.’
Centaurea Chrome Fountain (30) was new to me and our trials. Like coleus, if flowering was not part of the evaluation, this Centaurea would have received ‘Excellent’ standing because everything else is perfect performance-wise.
Pennisetum Graceful Grasses Fireworks (31) is not a new variety but it is colourful. Because it does not become overly large, this variety will enhance any combination in a center spot or beautify any landscape. This grass works well in all weather conditions. ‘Very Good’ standing.
Scaevola aemula Abanico Rose (32), along with the blue and white entries in this series, have been great performers for three years in a row. Like other scaevola, it
performs well in all weather conditions and keeps flowering with no setbacks from the rain or the heat. ‘Excellent’ standing.
Colocasia Coffee Cups (33) is a tropical that works well in Ontario summers. It overshadows most other genera with its large dark chocolate leaves that keep unfolding as long as the plant is kept moist. Great in any pot or landscape. In ‘Very Good’ standing.
Mandevilla Madinia Coral Pink (34) is one variety of many on the market. An elegant plant with durable performance and excellent garden performance, the more important aspect is how consumerfriendly it is. It offers a great show the whole summer long and it can be used in planters, landscape, or hangers. Definitely in ‘Excellent’ standing.

Rooting for success mid-air
Is there an advantage to using aeroponics? The answer seems to be up in the air.
BY TREENA HEIN
Aeroponics, as most know, is a growing method where fertilized water is misted or sprayed onto roots kept in darkened chambers.
Nozzle clogging, a historically common problem due to the nutrients in the irrigation solution, is now handled through the use of water pressure sensors and other technologies.
Collectively however, the entire aeroponics system (sensors, precision nozzles, software, etc.) still incurs higher capital costs than hydroponics. Are the end results worth the added investment?
“Aeroponics is another type of growing system for root zone management and requires sound knowledge using water as the only medium,” says Dr. Mohyuddin Mirza, an Alberta-based greenhouse industry consultant who has worked with hydroponic, aeroponic and nutrient flow systems.
ABOVE
“One can learn about the system, but crop losses can be avoided by gaining knowledge of water quality, nutrient ratios, recycling of nutrients and understanding how plants would response to a totally liquid medium. Growers must realize the importance of maintaining adequate levels of oxygen in the nutrient solution in an aeroponic system.”
Success with aeroponics requires much knowledge. Both root growth and the rootzone environment must be consistently monitored to ensure the crop’s success. While the nutrient solution can be completely recycled within an aeroponic system, growers need to carefully watch pH and mineral build-up. Some discard their water periodically.
As an example, Mirza shares a previous experience working with an aeroponic grower who had trouble maintaining the right level of bicarbonates
Do aeroponics produce superior products? Proponents say ‘yes,’ but their success may be rooted in the high precision and knowledge needed for this particular type of production system.
needed for pH buffering in the root zone. The growers were using reverse osmosis water which has no bicarbonates. As a result, the pH dropped below the required threshold so fast that it led to crop damage along with significant economic loss.
He points out that in the case of cannabis, the crop has a tendency to develop massive root systems as more photosynthetic assimilates are translocated to the roots rather than being supplied to the leaves, shoots or buds. “This is more pronounced in growing media which have unlimited water and nutrients,” he says. Growers must ensure that they have good knowledge of crop steering in the generative direction for water-based aeroponic or hydroponic systems.
In case of fertigation pump failure, Mirza points out that a back-up system would be critical. Plant root cells can only survive about 30 minutes without water, and as it turns out, aeroponics are not immune to pests and root diseases either.
“Growers should not assume that there will be fewer pests or diseases because of the use of an aeroponic system,” Mirza says. The roots secrete nutritious compounds or act as food themselves for fungi, pests and pathogens. Common culprits include Fusarium and Pythium. “In aeroponics, if you don’t pay attention to oxygen, root diseases can occur.”
“I have seen cannabis growers who started with aeroponic systems and then switched over to rockwool and/or coir-based media, simply because there were so many problems with root zone issues,” he adds. “On the other hand, I have also seen growers switching over to aeroponics because of the anecdotal mention of higher quality crops.”
With the depth of knowledge needed to successfully execute
Compared to vine crops, lettuce and leafy greens are typically more amenable to aeroponic systems.
an aeroponic system, could it be the high level of precision that, in the end, facilitates high quality results?
CANNABIS
For aeroponically grown cannabis, “roots are not bound by soil and expand root surface area with abandon,” says Phil
Cannabis tends to develop large root masses, particularly in media where nutrient availability is almost unlimited. Nozzles are used for fertigation.
with very high-intensity photosynthetic photon flux light density at the canopy surface results in very fast growth. High potency is also a result of this efficiency Anecdotally, our customers are seeing five to eight per cent lift in cannabinoid content from plants grown in aeroponics versus the same strains grown in soil media.” His customers, he says, have been able to sell their cannabis at premiums of 25 to 40 per cent above pricing for similar shelf products.
Gibson, vice president of marketing at aeroponic systems maker AEssenseGrows in Sunnyvale, Calif. With healthy roots and sufficient oxygen, proper aeroponic use could help the plant benefit from efforts to boost photosynthetic efficiency Cannabis, says Gibson, “loves this infinite nutrient feed. This, combined
One of AEssenseGrow’s customers is Grump Weed in Manitoba. President and CEO David Hargreaves says in addition to their choice of strains, Grump Weed’s use of aeroponics has helped create an extremely high-quality product, not just one high in THC. “We believe that smooth and clean smoke, good bud structure, bud density, trichome count, terpenes [and] flavonoids are all more important than THC,” he says. “Our main focus is increasing the quality of the product and in many ways, aeroponics helps us accomplish this.”
To ensure the cleanest growing environment possible, Hargreaves says

they clean every surface of every grow room daily and fully disinfect every week.
“A good-quality premium cannabis product starts with creating the cleanest and smoothest tasting cannabis on the market,” he observes. When asked about gaining the knowledge needed for success, Hargreaves says no one on his team had aeroponics expertise when they
started, but learned along the way. He explains that while the learning curve was large, having equipment that automates pH, nutrient levels, water temperature and spray cycles has helped a great deal.
FOOD PRODUCTION
Beyond cannabis, aeroponics is also being used in food production.
“Generally leafy crops like salads, herbs and those in which leaves are harvested, are more adoptable to aeroponic systems, although they grow well in soil or soilless cultivation systems as well,” Mirza says. “Vine crops like cucumbers, tomatoes and peppers are not well suited to aeroponic systems because of massive root growth and oxygen depletion.”
With its high costs and touted poten tial for producing quality products, it’s no surprise that aeroponics is being explored for high-value crops such as saffron.
In the field, growing saffron is complex, labour-intensive and yields are low. Within a controlled indoor growing environment, saffron could potentially be produced year-round with high yields and extremely high quality that is described as being ‘pharmaceutical level.’ In addition to saffron’s primary market as a high-end cooking ingredient, the plant is also used in cosmetics, natural medicines and dyes.
Based in Israel, Saffron Tech is de veloping a controlled saffron-cultivation system and recently entered an agreement with Israel’s largest agricultural research institute, the Volcani Center. Saffron Tech CEO David Freidenberg says they have

purchased AEssenseGrows equipment and may be in a position to work with it by the end of this year.
Another, perhaps unexpected, food crop that may be suitable for aeroponics is the potato.
In 2014, researchers at the Brooks research facility in Alberta explored the use of aeroponics for producing seed potatoes. More recently, researchers at Jiangsu University in China published a study on aeroponically grown potatoes in 2020. They found that the operational cost amounted to one-fourth that of field cultivation in China. In addition, much higher yields were possible within a shorter period of time. The scientists found that the growth phase could last for more than 180 days, with potatoes of the desired size continually harvested, causing the initiation of new tubers.
Globally, other aeroponic technology suppliers are targeting lettuce and herb production. One of these is Switzerlandbased CleanGreens Solutions, which has three installations so far of its mobile robotic systems; one in France and two in Switzerland, with two more starting in
“Our irrigation robot travels under the roots and thus this allows [us] to save [on] a lot of nozzles compared to fixed systems,” explains CleanGreens Solutions’ director of operations and procurement, Céline Calais. “It overall decreases the cost of the system but more importantly, it reduces maintenance needs.”
Calais notes that for those who are undecided between hydroponics and aeroponics, the potential yield difference could be an important factor. “Yields per square metre using our system are two to three times higher than hydroponics,” she says. “For lettuces, we reach yields of close to 1,000 tonnes per hectare per year and for most herbs, we are close to 400 tonnes per hectare per year.” Calais says that in hydroponic systems, lettuce heads tend to max out at about 300 g. By comparison, she’s seen Batavia lettuce heads that can easily reach 800 g with their aeroponic
In the U.S., AeroFarms sells microgreens and baby leafy greens from its aeroponic operation in New Jersey, and has operations under construction in Virginia, U.S. and Abu Dhabi, United Arab Emirates. “The next AeroFarms commercial farm will be located in the broader St. Louis region,” says Marc Oshima, AeroFarms CMO & co-founder. “We also have an…initiative, where ten community farms are coming online in Jersey City, New Jersey.”
FUTURE OUTLOOK
Looking forward, Calais believes increasing uptake and awareness along with continuous R&D and tech development will drive down the capital costs of aeroponics as these factors have done for every new technology.
“Remember the cost of a computer 30 years ago and look at its price now,” she says. For her customers, the technology checks all the boxes: reliability, profitability, food safety and environmental responsibility. “They like the newness of the technology and even push us to innovate more, especially in terms of automation of

This growth has been spurred on by a younger demographic, mainly culturally diverse female consumers. Garden Media Group, in their 2022 trends report, points out that flowers are the new ‘hug’ and have found a place in young consumers’ lives.
In the U.S. over 51 per cent of all cut flowers are purchased in major grocery stores. Corner grocery stores are also expanding their product lines and sales. Tech savvy florists are increasing their sales with online marketing. According to Pringle, a new generation of young people, like event planners and those he refers to as ‘Instagram folks and influencers,’ sell directly to clients.
In B.C. there are also a number of new flower farms that sell at roadside stands or charge admission for floral viewings and sales, as well as u-pick farms that sell seasonal flowers from early tulips to late dahlias.
Floral imports from Colombia, Ecuador and Africa continue to be slowed by COVID as access to vaccines has not been as readily available in those countries. In the meantime, local floral sales in B.C. have reached record numbers, says Pringle.
LOOKING TOWARDS 2022
In the lawn and garden industry, we’ve experienced two exceptional years of dramatically increased sales during a time when folks were homebound and wanted to beautify their surroundings. In the horticultural industry, the question on everyone’s mind is: Will this trend continue as the pandemic restrictions wind down and our consumers are free to travel more, attend sports and entertainment events and generally spend their disposable dollars elsewhere?
According to Dr. Charlie Hall, one of America’s top economic icons in the horticultural industry, we will be in fairly good shape for 2022. He points out, however, that if there was ever a time to hone your management skills, next year will be it. The combined issues of labour shortages, the uncertainty of overseas supplies, dramatically increased freight and overall operating costs, shortages of quality nursery stock and the shadow of inflation will create a more complex year ahead. Watching the bottom line will never be more important.
The Garden Media Group report predicts that the growth in gardening will stick, especially with the 18.3 million new U.S. gardeners, many of whom are passionate foodies and have a strong interest in growing their own food. There has been a decline in vegetable sales but a strong upsurge in the ornamental colour of flowering annuals, perennials and flowering shrubs.
crops will sell through, but if provinces can keep COVID on a downward trajectory and allow Christmas events, like staff parties, to take place in restaurants and larger facilities, the traditional demands for seasonal flowers could be strong. After the Christmas shutdown in 2020, many growers have been more conservative with their 2021 production, so there could be a good sell through on potted plants.
CUT FLOWERS EMBRACED
The cut flower industry has been a rising star during the past two years.
Bob Pringle, the CEO of United Flower Growers in Burnaby, B.C., informed me that, in spite of the loss of corporate events, traditional weddings, funerals, and graduations due to pandemic restrictions, there has been a tremendous increase in demand for locally grown cut flowers, both from year-round
For retail, Garden Media Group believes that future shopping will be a hybrid of in-store experiences and virtual shopping.
Both Dr. Hall and the Garden Media Group suggest that there will never be a more critical time to market the benefits of plants relative to our personal well being. With the Millennials’ strong connection to nature and wildlife, we also need to keep reminding folks of the importance of plants for pollinators and beneficial insects.
From all my anecdotal research and discussions with many leaders in the industry, the current consensus is that 2022 sales should fall somewhere between those of 2020 and 2021 in North America. Next year will be a challenge to be sure, but with the cloud of COVID seemingly lifting, we can surely look forward to brighter days ahead.

Two years in: Local farming project soars in First Nation community
This container garden has become a fresh produce staple for the Norway House Cree Nation.
BY STEPHANIE GORDON
It’s been two years since Virginia Muswagon and Ian Maxwell started growing fresh produce for Norway House Cree Nation using a hydroponic container garden.
Together they are co-managers of Life Water Gardens (Pimâtisiwin Nipî Kistikânihk) and they seed, harvest, and deliver fresh produce to their local community weekly.
Norway House Cree Nation is one of the largest Indigenous communities in Manitoba, Canada,
with a growing population of 7,500 community members.
The area enjoys all four seasons so growing outdoors is limited to the warmer months. However, the addition of a 40-foot hydroponic container garden unlocked the ability to grow fresh vegetables year-round – even at temperatures below freezing.
The operators grow kale, spinach, lettuce, pac choi, and a variety of herbs like cilantro, basil,

parsley, and mint. Muswagon and Maxwell also have a packaging container where they store, package and prepare their deliveries to the local school or hospital.
GROWING THE NEXT GENERATION
Every week, Maxwell delivers the harvest to the local school who is their largest customer.
“The biggest impact is at Helen Betty Osborne [Ininiw Education Resource Centre] . . . [where] 600 to 700 students are consuming our produce every day,” Muswagon says.
The local school has 1,500 students, a vast majority of which are Indigenous. Students are able to visit the cafeteria starting in grade 6, and older students in grades 9 and up help in the cafeteria occasionally preparing salads, sandwiches, soups, and other meals.
“We need to introduce this [healthy eating] at that age or even younger . . . and the chef there is really happy with our produce . . . if you can see it, it speaks for itself,” Muswagon says.
The locally grown produce also stays fresher for longer compared to the waterlogged produce they’ve seen before.
“I’ve been nothing but pleased,” says Kyle Mohr, the culinary arts instructor at the Helen Betty Osborne school. “Virginia is a wonderful role model for the community getting a business up and running.”
Mohr explains how he regularly communicates with the Life Water Gardens team, so the school knows how
much to order.
If there’s any extra produce, it doesn’t go to waste. For example, any extra spinach is steamed off and vacuum sealed to be used by home economics classes to make spinach dip, soup, and quiches.
“If we give them enough lead time, they’re able to put together a package and
Inside the container farm, the operators grow kale, spinach, lettuce, pac choi, and a variety of herbs like cilantro, basil, parsley, and mint.
OPPORTUNITY TO TURN A HOBBY INTO A CAREER
Virginia Muswagon and Ian Maxwell didn’t intend to be running a container farming business, but they both were interested in growing plants.
“Even though I don’t have a degree in botany or any official title, I’ve always been interested in gardening,” Maxwell shares. “Super excited to have this kind of project.”
“With me, I remember when my mum and dad were alive, my dad started up a greenhouse and he also grew potatoes,” Muswagon says. She shares how when her dad would bring the fresh harvest to the table she grew to love produce straight from the garden. “I find it more tasty, and that’s when it started for me.”
While weather is less of a concern in an indoor controlled environment, working in the hydroponic container garden still requires hands-on nurturing of the plants. Maxwell shares how they’re still learning as they go and engaging with the community to guide their decisions for the future of the project.
have [what we request] grow over the course of over three or four weeks,” Mohr says. “It’s customizable which is great for us.”
The culinary program at the Helen Betty Osborne school, according to Mohr, tries to give youth an opportunity to work in a commercial kitchen. The students are taught marketable skills such as knife skills, sanitation, and how to use commercial grade equipment. The locally grown produce adds to the mix and keeps the program interesting.
“I’ve worked in a number of northern communities, and I’ve never seen anything like this before. This is unique and fantastic for the whole town,” Mohr says.
“[At this point,] we’ve established ourselves as self-sufficient,” Maxwell says.
THERE’S ROOM FOR BIG AND SMALL IN VERTICAL FARMING
Ottawa is the home base of The Growcer, the company that built the hydroponic container garden and is there to help Maxwell and Muswagon grow their project.
Since 2016, the company has grown to partner with more than 25 communities across Canada to grow hyper-local produce yearround through its hydroponic modular farms. What started as a

solution for food insecure, remote places expanded as an impactful idea for communities who see the value in growing locally.
“The common success factor we see is we have a handful of community members who enjoy food, gardening, helping fellow community members, and supporting youth . . . Ian, Virginia, they are the primary reasons why the projects are so successful,” says Branavan Tharmarajah, head project consultant with The Growcer. “There’s a handful of community members who take it upon themselves to help others in the community and they take pride in that, and that’s one of the biggest factors of success.”
The modular hydroponic farms are a fraction of the size of larger warehouses also used for vertical farming, but it’s all part of the product mix.
“Just like with renewable energy, we need a variety of vertical farming solutions at different scales to suit different applications,” says Corey Ellis, CEO of The Growcer. “Similar to how we need solar panels on our homes, which coexist with larger solar farms. They both work toward the same goal in different ways.”
The container gardens fit the needs of the communities who use them, like Norway House Cree Nation. But the biggest impact for Ellis is the human aspect.
“For the operators of Growcer farms, the impact is life changing,” Ellis says. “I’ve seen countless
times when someone’s decision to become a container farm operator shifted their entire career trajectory. At Growcer, we are fortunate to get to watch as they grow into their new lifestyle, master the challenge of keeping plants healthy, and ultimately, take pride in providing fresh food to their local community.”
EXPANDING BEYOND THE COMMUNITY
With two years under their belt, Life Water Gardens plans to expand and add more containers to build a multi-container garden that can feed more people.
Maxwell shares that they currently deliver produce to the local hospital, but also hope to be able to provide greens to the new hospital being built in Norway House. The expansion will create more jobs and expand the Life Water Gardens staff beyond the current team of five.
Norway House Cree Nation also serves as a gateway to the Northern and Eastern communities of Manitoba, and there’s potential to supply fresh produce to the neighbouring communities in Cross Lake, Thompson, Flin Flon and The Pas.
The community-led solution has the potential to change what freshness means to the next generation living in the north.

PERENNIAL PHLOX IN THE SPOTLIGHT
BY DIANE BLAZEK
Phlox is a wide-ranging North American native perennial and a common fixture in woodland, prairie, and meadow landscapes. The wildflower can be easily found in areas stretching from Florida in the southern U.S., through Quebec and into Alaska.
One of the classic perennials, this was one of the earliest North American natives to enter cultivation. With vibrant flower colours and blooms lasting many weeks, it is easy to understand what caught the eye of so many gardeners – and pollinators –through the years.
Although there are phlox species that grow as annuals, this year’s All-America Selections’ program chose perennial phlox as its ‘Year of’ crop in the perennials category.
BASIC TYPES
Phlox is a genus with a multitude of species, heights, bloom times, and garden applications. Many of these species are unrecognizable to the average gardener but are becoming more common in new interspecific hybrids. Through all of the diversity, perennial phlox can be loosely grouped into two types: spring bloomers and summer bloomers.
Spring Bloomers (creeping/groundcover types): Phlox subulata (Creeping Phlox, Moss Pinks) and other early-spring blooming species are low growing, ground-hugging plants. Typically native to rocky, well-drained environments, when put in a garden without restriction they become carpets of colour. Most of these types tend to spread and work well as groundcovers.
Summer Bloomers (tall garden phlox and related types): When referring to phlox, most first think of tall garden phlox (Phlox paniculata). This clump-forming perennial blooms in midsummer and is among the tallest of the phlox species. Also characteristic of tall garden phlox are the perfectly formed large, rounded flower panicles that top each stem.
In addition to tall garden phlox, summer blooming species (including Phlox glaberrima and Phlox pilosa to name a few) are becoming more common, particularly in interspecific hybrids. Hybrid garden phlox tend to bloom a bit earlier, have a more
mounded shape, and a stoloniferous habit. Also characteristic of summer bloomers is a propensity to rebloom after the first flush of flowers, particularly when trimmed back.
VARIETIES OF NOTE
• Luminary Phlox paniculata: This mid-sized series averages around 2½-3’ in height and shows excellent vigour and mildew resistance.
• Opening Act Phlox hybrid: A mid-height series of upright phlox, averaging 2-2½’ tall. Excellent rebloom and mildew resistance.
• Fashionably Early Phlox paniculata: 2-3’ tall series bred for early and long-season flowering with rebloom in the fall.
• Jeana Phlox paniculata: A classic native selection with long panicles of compressed flowers; very popular with pollinators!
• Sweet Summer Phlox paniculata: A compact series of tall garden phlox at 1½-2’ tall with good mildew resistance.
• Super Ka-pow Phlox paniculata: A well-branched series of tall garden phlox at 18-20” tall with good mildew resistance.
• Woodlander Phlox hybrid: A series of interspecific lowspreading phlox with large flowers.
• Spring Bling Phlox subulata: This series of creeping phlox has excellent garden resilience and a long season of bloom.
• Drummond’s Pink Phlox subulata: An exceptionally vigorous creeping phlox with large pink flowers.

WATER DNA TESTS: Pros, Cons and Interpreting Results
With water samples in hand, it’s now time to confirm the pathogens within. Here’s why you should consider a DNA test and how you can best interpret the results.
BY: DR. SARAH JANDRICIC AND DR. ANDREW WYLIE
So you’ve identified potential sources of pathogens in your greenhouse and collected the necessary water samples. What now?
The next step is to identify the pathogen(s) which will then allow you to treat your water issues and prevent unnecessary fungal or bacterial diseases in your greenhouse crops. This could potentially save you thousands of dollars in crop losses or fungicide applications.
In the last article in this water sanitation series, we focused on ways to sample water sources and potential tests that can be run. Now that you’ve got your water sample, let’s find out more about water DNA tests and, specifically, why they’re useful and how you can interpret the results.
WHY SHOULD I GET A DNA TEST ON MY WATER?
Sampling from all points along your water system – from your pond to your misting lines –can help narrow down sources of contamination in your greenhouse using DNA tests.
If you’re testing your water, it’s likely because you either a) have an undiagnosed disease problem in your greenhouse already, or b) you want to head off any issues that could be caused from your cistern, roof water, or water lines. Even with disease symptoms present, it can be really difficult to nail down the culprit pathogen – and the right fungicide – without a DNA test. Overall, DNA tests are the gold standard, for many reasons:
choose to look specifically for fungi, bacteria or both.
• Multiple samples can determine where a problem is coming from. If you take samples from multiple points along your water system, and disease issues are only detected in one area (e.g. a secondary holding tank), or are especially high in one area, this can narrow down the source of the problem. (See our case study later on for an example.) This can potentially save you thousands of dollars in crop losses and unnecessary fungicide application by eliminating recurring disease issues at the source.
Sampling from all points along your water system – from your pond to your misting lines – can help narrow down sources of contamination in your greenhouse using DNA tests.
• DNA doesn’t lie. It’s surprising how much symptoms from one disease can look like those from another sometimes. Even an expert with years of experience can make a mistake when it comes to diagnostics from just signs and symptoms – especially diseases that cause root rots. With DNA tests, you can be sure.
• They can screen for multiple pathogens. One of the DNA tests available, the DNA multiscan, does just that – it scans for multiple pests at one time. This test can point towards a disease issue you might not have even considered. You can
INTERPRETING RESULTS
Despite the benefits of DNA analyses, as with any tool, they aren’t perfect. They require some know-how (or asking experts) to provide the correct interpretation of results. You still need to be an investigator of sorts, using your DNA results plus other pieces of information to come to the right conclusions.
Here are some things to keep in mind when interpreting a DNA test, including DNA multiscan results:
1. Look for specific pathogenic species on the results
Shown above is an example of the output from a DNA multiscan test. It’s often useful to run the results of your DNA lab tests past a disease specialist, as some fungal species have beneficial strains. “High” loads of a certain pathogen don’t always mean it’s the main culprit.
output. For example, positive test results for “Fusarium” in DNA results – without indicating an actual species – are likely false leads, since there can be beneficial or nondisease causing species of Fusarium. You want to look for specific species known to cause disease, e.g. Fusarium oxysporum. When put together, positive DNA test results for an actual pathogenic species from your water and/or a diseased plant, paired with matching disease descriptions of symptoms in your crop (from an accredited source), strongly suggest a specific culprit.
2. Be cautious of “low” versus “high” pathogen loads on DNA multiscan results. It can be tempting to go down the list of positive results on a DNA scan and assume that the results that came back at the highest levels are the true culprit, but it doesn’t always work this way. Some pathogens are often present at low levels (like Pythium) without causing disease, and other pathogens cause significant disease at very low pathogen loads. For example, whenever I see a positive result for Thielaviopsis (black root rot) – high or low – from a plant or water sample in a greenhouse that grows susceptible crops, I immediately tell the grower to put on a preventative fungicide application. Black root rot produces resting spores that are hard to kill and are easily spread, and can cause infection even at low levels.
3. Be aware that DNA analyses can’t tell you if a pathogen is alive or dead. Similar to crime scene tests, they just detect DNA fragments. This means that you may need more than just a DNA test to go on (more on this later).
4. Understand that DNA tests can’t directly tell you if your treatment is working or not. This is because of point #3, above. Testing your water before and after water treatment may show differences in pathogen loads, but without knowing if the pathogens survived the water treatment, that’s not of much use.
5. Know that DNA analyses can be paired with more
specific tests to help determine water treatment efficacy. For example, if you run a DNA multiscan on your water, and multiple pathogenic species come back positive on the test, you may want to ask the lab to try to “plate” or grow suspected pathogens pre/post-water treatment on specific media. Plating makes sure that a specific pathogen found in your recirculating water is actually alive and has the potential to cause issues.
CASE STUDY: DNA MULTISCAN TO THE RESCUE
One of the most powerful aspects of DNA analyses is to help determine what you actually have, versus what you think you may have.
For example, a greenhouse in Ontario had a yearly problem with a certain percentage of their poinsettia crop wilting and dying starting in mid-September. Because poinsettia commonly are susceptible to Pythium aphanidermatum and Pythium ultimum, the growers naturally assumed that this was the problem. They applied the appropriate chemicals. When this didn’t fix the problem after several seasons, the growers thought they might have had a fungicide-resistant Pythium strain.
To be sure of what we were facing, we had multiple symptomatic plants tested individually across the entire crop. This gave us a good sample size to make conclusions from.
Surprisingly, the DNA multiscan results showed that only Fusarium was present in all 12 samples. Fusarium oxysporum in poinsettia is rare, but not unheard of, and it actually is affecting poinsettias more and more. The test showed no evidence of more common pathogens in poinsettia, like Pythium or Phytophthora, and follow-up trials with Fusarium-appropriate fungicides showed results. This last step was important for identifying Fusarium as the causative agent, as there are some strains of Fusarium oxysporum that are actually beneficial.
Although this testing process was expensive ($250 per sample, 12 samples), it has since saved the grower thousands of dollars over the years in crop losses and unnecessary applications of the wrong fungicides.
Further, this greenhouse was then able to use DNA multiscans of their water to determine where the Fusarium inoculum was coming from. After testing all areas, we ultimately found out that the culprit was the potting line using recirculating water. The water was sometimes re-used between crops that had different susceptibility to Fusarium. After fixing this sanitation issue, the grower hasn’t spent another cent on fungicides in their poinsettia crop since!

Organic soil conditioning for rapid crop growth
Jean-Pierre Fortin
ver the past few years, demand for organic products has continued to rise, so much so that organic crops can now be found in all industry sectors including fruit and vegetable production, ornamental growing and even cannabis farming. By promoting healthy nutrition and ecofriendly practises, the organic growing philosophy has decidedly become the trend of the future. Nevertheless, embracing this trend for commercial crop production does have its share of challenges…
Fertilization: the Achilles heel of organic growing
In organic growing, preference is given to natural and organic fertilizers. Although these perform as well as their synthetic counterparts, plants do not easily assimilate the essential elements they contain. How to rectify this situation and make the most of your organic soil? With conditioning!
What does organic soil conditioning involve?
Organic soil consists of natural ingredients. It contains elements that are essential for plant growth deep inside its structure, making them difficult to access. Conditioning helps to trigger nutrient mineralization. It also activates the growth of microorganisms, which process the nutrients into a form that can be absorbed by the roots and assimilated by the plant.
Why is conditioning good for organic soil?
There are several benefits to organic soil conditioning, for instance under the following circumstances:
It compensates for shorter crop growth and short time to market
Products like tomatoes and peppers are long crops, giving the mineralization process the time it needs to unfold.
Inversely, leafy vegetables, fine herbs and sprouts make their way to supermarket shelves after just a few weeks – before mineralization is naturally triggered in time to satisfy short crop needs.
It synchronizes the availability of these elements with crop growth
Leafy vegetables need a lot of nitrogen over a short time. Tomatoes need a steady supply of nitrogen however they need a lot of potassium during fruit production. Sprouts need all the elements over a period of 2 to 3 weeks. Conditioning allows the elements to be mineralized as needed.
It enables the more sustainable and ecological management of natural resources
Several producers satisfy the immediate needs of their organic crops by increasing their organic fertilizer application in a way that is disproportionate to actual needs. Conditioning helps to reduce the quantity of fertilizer used by increasing the availability of the elements already present.
It promotes access to nitrogen
Nitrogen is among the most – if not the most –recalcitrant in terms of organic availability. Nitrogen is mainly imprisoned in proteins and amino acids. Proteins are in fact composed of chains of relatively complex amino acids. Every amino acid traps at least one nitrogen molecule. This nitrogen only becomes available if the protein chains and the amino acids that compose them are hydrolyzed. Hydrolysis is an enzymatic reaction that splits the proteins and amino acids. The microorganisms lead this process, drawing their nutrients and energy from many organic molecules including the proteins they break apart. The nitrogen is freed by the end of the process in an ammoniacal form not used by plants. Another class of microorganism, nitrifying bacteria, can convert ammoniacal nitrogen into nitrate, which is easily absorbed and assimilated by plants.
How to condition organic soil?
To effectively condition the soil, we need to stimulate the microorganisms by providing them with an environment and with nutrients conducive to their growth.
Oxygen
Just like humans, bacteria draw their energy from breathing, which involves burning carbon hydrates (sugars). They have a constant need for oxygen.
Water
Hydrolysis occurs in the presence of water. In fact, one water molecule is used during each step of decomposition. Water is also essential in maintaining the cellular structure of
bacteria and it participates in numerous metabolic reactions. A water supply is essential to microorganism development.
Temperature
Just like plants, microorganisms perform best at specific temperatures. Temperatures above 28 °C are preferable for certain species. Nonetheless, studies show that mineralization occurs rapidly between 20 °C and 25 °C.
pH
Although some microorganisms can accommodate a pH that is either very low or very high, optimal pH for mineralization is between 7.6 and 7.8, which is more alkaline. The bacteria involved in the process are nonetheless able to adapt to the soil’s pH (5.5 - 6.5).
Time
Time is the final factor that contributes to successful conditioning. The microorganism population must peak to ensure an effective mineralization rate. It takes a minimum of 2 weeks to achieve optimal cruising speed.
NITROGEN GENERATION USING ORGANIC FERTILIZER
What can we expect from conditioning?
Studies have demonstrated the effectiveness of conditioning. We compared the analyses of unconditioned organic soil to soil conditioned for 2 to 4 weeks. The results were conclusive, indicating low nitrogen levels in the unconditioned soil. Moreover, this nitrogen was nearly entirely present in ammoniacal form. Testing revealed 2.5 times more nitrogen at the end of 2 weeks of conditioning. Additionally, 90% of the nitrogen was in nitrate form. Conditioning prior to use helps to release the nutritional elements in a form that can be directly assimilated from the time of planting.
What are the steps to conditioning?
Conditioning involves four steps: remove the soil mix from the packaging; moisten it until its humidity level reaches between 60 and 80% (on a weighted basis, water weight/soil weight); leave it to swell to incorporate oxygen; and let it rest long enough for the mineralization process to occur.
As illustrated on this graph, the feather meal was incubated and regularly tested to monitor the nitrogen forms following the mineralization process.
Ammoniacal nitrogen was clearly the first nitrogen form to register. The nitrogen was converted into nitrate only after 2 to 3 weeks of incubation.

For long crops, conditioning can take place directly in growing containers or tubs. For medium duration crops (potted fine herbs, vegetable plants, leafy vegetables), the containers can be filled up in advance, stored, and kept moist for planting. Finally, short crops require more organization. For these, the soil must be stored under proper conditions until the germination trays are planted. Ideally, a special soil conditioning space could be organized near the potting room. The size of this area should correspond to required weekly volume.
Conditioning is an additional step in growing preparation, but it is vitally important because it helps to guarantee the crop’s efficiency and success!

Tasteful production of greenhouse lettuce
Purpose-built Alberta greenhouse continuously searches for ways to finetune specialized lettuce production.
BY GRETA CHIU
Deep in the heart of southern Alberta lies Whole Leaf, a five-hectare greenhouse that was not only purpose-built for lettuce production, but specializes in the consumer taste experience.
“It’s fully automated [and] fully robotic, so we can be more cost competitive and close the cost parity gap with field-grown. We are striving to provide the ultimate freshness and taste experience,” explains David Karwacki, co-founder and CEO of the Star Group, which owns and operates Whole Leaf in Lethbridge County, Alta. The greenhouse produces approximately 18 million heads annually, allowing them to generate the same amount of produce as 600 field acres.
The Star Group has set their sights on the

future of smart growing, and Karwacki says Whole Leaf is their north star. In addition to sophisticated automation, the facility sequesters CO2, uses waste heat, feeds electricity back into the grid, and is meticulously conscious of water waste and consumption.
“We’re only using one litre of water per head of lettuce,” he says, comparing it to the average 100 to 150 litres typically employed in field production. They chose the nutrient film technique (NFT) as a way to gain greater control over the growing environment. The water is run through a filtration system that includes ultraviolet and microfiltration and is tested frequently ensuring cleanliness and safety.

The start of a fruitful venture
Similar to Whole Leaf’s approach to lettuce, The Star Group is working on combining the right genetics with the right environmental conditions for yearround production of greenhouse strawberries, led by BC Hot House Foods in Surrey.
“Strawberries are very difficult to grow and very complex,” says David Karwacki. “Often times, they’re bred for yield and they’re bred for shelf life, but not necessarily bred for taste.”
“But when … they’re red all the way through, they explode in your mouth, and they have a great sweet taste at the front and maybe a little bit of acid at the back? Boy, you just can’t stop eating them.”
The project received $380,000 in support via the Canada-British Columbia AgriInnovation Program in 2020. They’ve since been working with their partners in Europe to create a feasible cultivation method under lights.
“You can do it, but can you do it economically?” Karwacki poses. “Can you get the right taste [and] … berries that have the same size, texture, taste, colour and shape that you want? It’s a pretty exciting project to be a part of.”
Producing for both food service and retail markets, the team continuously stays in tune with what consumers and restauranteurs are each looking for.
“For me, the best thing is it’s pesticide-free,” says Karwacki.
The first 2.5 hectares were completed in 2017 followed by an immediate 2.5-hectare expansion completed in 2019. The greenhouse was specially outfitted to grow whole heads of lettuce, sold either in a living format or washed and ready for consumption in packaged clamshells.
It took the team two years to get a good understanding of the growing conditions and technology. “It’s a constant learning environment that challenges our growing team to continue raising the bar on what’s possible for greenhouse leafy greens,” he says.
There was a lot of trial and error. No one had the expertise that could tell them exactly how to execute it. They needed to understand how the technology worked together and in conjunction with the environment.
“We are able to control all of the different variables, but when a chinook comes off the mountains of southern Alberta, and the temperature outside our greenhouse changes by 25 to 30 degrees in an hour? That can have very, very dramatic effects on the crop.”
Climate, humidity deficits, night- and daytime temperatures, CO2, varietals, as well as the
water’s flow, temperature, and nutrients – every variable influences the final product. As for lighting, Whole Leaf soaks in as much sunlight as possible, supplementing with artificial light when needed to grow year-round.
LOOK, FEEL, TASTE AND TEXTURE
Growing for both retail markets and restaurants, Whole Leaf produces seven different types of greens across nine varieties and each one is tailored specifically to a segment and client. In 2020, quick-service restaurant chain, Wendy’s Canada, launched a campaign to source only Canadian greenhouse-grown lettuce for their burgers and salads – all supplied by Whole Leaf.
“Restauranteurs want the perfect burger leaf,” Karwacki explains. “We can grow a head of lettuce with perfect leaves on it, and it takes all of the work out of the back shop where they do not have to carve up the lettuce anymore like they used to.” Not only are the leaves uniform in size, the team has also worked to grow varieties of lettuce with greater resistance to wilting, a textural frill along the margins and a lighter, more blonde colour.
As for consumers shopping at retail grocers? They’re focused on freshness, crunch and taste,
Working closely with seed providers and breeders, Whole Leaf experiments with their production practices to get the right characteristics for each target segment.
says Karwacki. Sold under their consumer brand Inspired Greens, the Tender & Tasty Trio living lettuce has been one of their most popular products. Each trio head contains a bouquet of three different leaf types, offering a contrast of taste, texture and convenience in just one cut.
To ensure the right characteristics, Whole Leaf not only changes up their growing practices but works with seed companies worldwide. Trials are conducted right inside their greenhouse, allowing them to efficiently address feedback from retailers and food service providers. “That may take two [to] four years to cycle through the process [to] get what consumers are really looking for,” Karwacki says. “Ultimately, our objective is to find and grow lettuces that consumers love.”
“You can get anything from nutty to peppery to buttery. The crunch and crispness, the texture of the lettuce, [they] play into the taste profile, the mouthfeel that you’re going to get out of it,” says Karwacki. Where the deeper green lettuces often deliver a more earthy taste, the blonder types have a higher level of sweetness. While most red varieties tend to be bitter, Karwacki says theirs are not, which is an unusual and positive surprise.
“A lot of lettuce was bred for the field and really was not particularly oriented for greenhouse growing,” he explains. But here, they’ve seen a big shift in recent years. “There are all kinds of taste profiles out there. Breeders are doing an outstanding job in coming up with new varieties that work in the greenhouses to bring out better flavours and better crunch and the characteristics that will delight consumers.”
By going back to the genetics, revising their growing practices and better understanding consumer wants, Whole Leaf has seemingly uncovered a formula that resonates with today’s markets. It’s an approach that the Star Group is using to fuel their latest venture in B.C. with greenhouse strawberries, and it’s also well-timed.
With a rise in home cooking spurred by the COVID pandemic, Karwacki has seen consumers becoming increasingly aware of the products they consume.
“When you think about the food provenance movement, and how people are wanting to understand where their food is coming from, how it’s being grown [and] handled - that’s becoming more and more important. And I think in the face of COVID, it’s become even more acute.”
Expanding consumer reach
In 2020, The Star Group launched their InspiredGO digital platform, which delivers their prepackaged Inspired Salads straight to consumer homes and offices in Calgary, Vancouver, Edmonton, Saskatoon and Winnipeg. Throughout the COVID pandemic, their team has provided over 15,000 meals and counting to frontline workers.
2021 was a year of recognition for the company. Whole Leaf’s Inspired Salads won the award for Best New Product at the 2021 CPMA showcase earlier this year. Their Wendy’s Sandwich Leaves & Salad Blend won the Innovative New Product Award at the 2021 CEA Awards, presented by technology supplier, Artemis.
Diseases affecting production of cannabis in greenhouses
Many destructive diseases can affect cannabis. Here’s how to recognize them.
BY ZAMIR K. PUNJA AND LIAM BUIRS
The production of cannabis in greenhouses is faced with challenges from various diseases, many of which are similar to those already found on other horticultural crops, such as tomatoes, cucumbers and peppers.
Fusarium and Pythium species cause root and crown rots which result in wilting and, in some instances, death of the plants. Powdery mildew is common on cannabis plants and develops rapidly under suitable environmental conditions. Destructive diseases which affect the flower clusters (buds) are caused by Botrytis cinerea and Fusarium species. Molds that develop after harvest can reduce quality and product acceptance. Last but not least, the recent detection of viroids and

viruses affecting cannabis will present challenges for producers going forward.
Disease management requires identification using diagnostic methods in addition to assessing how they were introduced and spread within the facility. By implementing strict sanitary procedures and establishing a disease management program that meets the regulatory guidelines established for this crop, producers can reduce losses. Different strains of cannabis from different genetic backgrounds (genotypes) vary significantly in response to pathogen infection and further research is needed to characterize them.
ROOT-INFECTING PATHOGENS
Root infection, caused by species of Fusarium and
Similar to other greenhouse crops, cannabis plants are also susceptible to various diseases including Fusarium. Internal infection can appear as discoloured stem tissue when cut open.

Figure 1: Symptoms of Fusarium infection on cannabis include internal stem discolouration on stock (mother) plants [a,b,c] from which the pathogen can be isolated [d]. Infection can result in damping-off [e], stunting [f], yellowing [g] and plant death [h].
Pythium, initially appears as a browning of roots, followed by loss of root hairs, giving rise to a poorly developed root system. Symptoms may appear as early as during the rooting stage of cuttings in propagation.
Pathogen sources may be from contaminated growing media or containers, recirculated water, irrigation lines, or from workers handling plants. One important source of Fusarium is mother (stock) plants [1a], which may harbour internal infection seen as a discolouration of the stem tissues when cut open [1b,c,d]. There may be no external symptoms on these plants
Fusarium is transmitted through cuttings taken from diseased plants, resulting in early symptoms of yellowing and damping-off [1e]. If diseased cuttings survive, additional symptoms of stunted growth and poorly developed roots may be seen [1f]. Plants without obvious symptoms can still display yellowing of leaves and underdeveloped flowers at later stages [1g]. Under environmental stresses (high temperatures, insufficient or excessive water, damage to roots), plants develop more rapid symptoms [1h].
Pythium causes more damage at the vegetative growth stage, with crown and rot root that can cause early plant death [2a-f]. More advanced infection on flowering plants can lead to rapid plant wilting and death, especially during periods of high temperature, due to extensive rotting of roots [2g]. Symptoms of infection include yellowing and plant death [2h].
Management Options: It is important to confirm that a causal agent, such as Fusarium or Pythium, is associated
Figure 2: Symptoms of Pythium infection on cannabis include stunting and wilting [a,b], root and crown rot [c] from which the pathogen can be isolated [d]. Symptoms on flowering plants include yellowing and wilting [e], root and crown rot [f] and plant death [g]. Symptoms can be reproduced following artificial inoculation [h].
with the symptoms seen on cannabis plants, as this allows one to rule out problems associated with fertility, water quality and other factors that can reduce root development and growth and cause similar symptoms.
Where possible, confirm the identity of the pathogens from diseased samples. Most producers can submit samples to commercial diagnostic laboratories to confirm the presence and severity of the pathogenic infection. Once diagnosed, all possible sources by which the pathogen may have been introduced should be explored.
If rooted cuttings are outsourced from a supplier, they should be quarantined for at least one week to assess for symptom development or tested for pathogen presence before being used. This outsourcing has been a major cause of pathogen spread
in many growing regions in Canada. The sources of growing media, water quality, and other avenues for contamination should also be explored.
Sanitation is an important aspect of disease management, so all areas and equipment used in propagation should be cleaned with approved products and regularly inspected.
Biological control products currently approved for use in cannabis production can provide protection from root pathogens. They should be applied early during the rooting stage and again during vegetative growth. Microbial products, based on formulations of Trichoderma, Gliocladium and Bacillus species, provide protection but will not control diseases which have already become established. Producers can evaluate which
products are best suited for their production method. The extent to which these beneficial microbes become established on cannabis plants and how they reduce disease development still needs further research. Do different strains of cannabis resist infection by Fusarium or Pythium species? We don’t have a definitive answer yet.
POWDERY MILDEW
Symptoms of powdery mildew infection are easy to identify as white patches of growth on the surfaces of leaves or bracts [3a].
The powdery mildew fungus (Golovinomyces species) develops inside epidermal cells of affected tissues and reproduces on the surface of the diseased tissues, producing large numbers of spores [3b] that can be transported by air, workers or on cuttings taken from
infected stock plants. Powdery mildew infection is favoured by humid, warm conditions (>70% relative humidity and temperatures of 24-30°C).
Certain strains of cannabis are quite susceptible, while others show a high level of resistance. Research is underway to characterize these resistance strains and to determine how they can be used in a breeding program. The range of plant species also affected by cannabis-infecting Golovinomyces requires further study.
Management Options: To manage powdery mildew, cannabis producers can start by selecting less susceptible strains.
The use of vaporized sulphur can also significantly reduce disease if applied for two to eight hours during night-time for several days a week. The use of sulphur
Figure 3: Powdery mildew infection causes white fuzzy growth [a] with lots of spore production [b]. Bud rot caused by Botrytis results in browning and rotting of the buds [c,d,e] from which the pathogen can be isolated [f]. Fusarium bud rot results in pinkish-white mycelium [g] and a distinct red appearance of the pathogen [h] also shown on the right.
should be balanced with the potential negative impact on insect biocontrols. Exposure of plants to artificial UV-C light from hand-held lamps or mechanized booms for brief daily periods of time (not exceeding 10 sec) has been shown to limit powdery mildew development. Weekly application of products that contain potassium bicarbonate is also effective at managing powdery mildew. Biological control products still need to

occurring during late summer and fall months. Botrytis infections are significantly reduced at 28 to 30 °C or higher. More recently, bud rot infections due to Fusarium species are causing concern for producers [3g,h]. These can develop throughout the year since the pathogen can grow at 15 to 35 °C.
be assessed to establish the best environmental conditions under which they could be used. Removal and disposal of infected leaves may slow down the development of powdery mildew.
BUD ROT PATHOGENS
At the time cannabis buds reach their fully developed stage and approach harvest (usually in weeks 6 to 8 of the flowering period), bud rot pathogens such as Botrytis
Cannabis strains that produce large and compact inflorescences create a microclimate that favours growth of the pathogen internally, and these are more susceptible to bud rot infection. Similarly, the presence of a large number of bracts surrounding the buds can enhance bud rot development by providing a suitable microenvironment for spore germination. Detailed comparisons of the architectural structure of cannabis flower clusters will provide more insight into how bud rot develops on different strains.
The ambient environmental conditions which promote pathogen development are relative humidity levels of over 75% and temperatures in the range of 15 to 25°C, making this a seasonal disease
Management Options: The sources of Botrytis and Fusarium inoculum on greenhouse cannabis may include spores released from decaying vegetation, from diseased plants within the greenhouse, or from neighbouring crops in the vicinity of the greenhouse.
To reduce the level of spores and spread, the removal of diseased buds is highly recommended. Modifying the greenhouse environment to maintain drier and hotter conditions with humidity levels below 60% reduces growth and spore production by the pathogen as well.
At present, the implementation of biorational approaches to reduce bud rot development is under investigation. Similar to the early applications of beneficial
microbes made to rooted cuttings for the prevention of Fusarium and Pythium, there is ongoing research to explore whether competing microbes can reduce bud rot when applied to the buds prior to Botrytis infection. Similarly, sprays of products containing ingredients such as hydrogen peroxide or potassium bicarbonate, if made without causing injury to the tissues or increasing moisture within the flower bud, may limit pathogen spore production and spread.
POST-HARVEST MOLDS
There are a number of factors that can promote mold development on buds after harvest. These include, but are not limited to: any disease symptoms that may be present at harvest, the population of molds in the air of the growing environment and trim rooms, the manner in which the buds are handled, and drying and storage conditions, especially air circulation, temperature and relative humidity.
The most prevalent species of fungi identified to cause post-harvest mold problems include Penicillium, Aspergillus and Fusarium. Remediation efforts should address reducing disease development on plants prior to harvest, reducing mold levels in the air, preventing excessive damage to buds during processing, and adjusting drying rooms to provide ideal conditions.
VIRUSES AND VIROIDS
Recent reports indicate that viruses and viroids are causing as yet undetermined reductions in growth and quality of cannabis.
The most prevalent at this time are Hop Latent Viroid (HLVd) and Tobacco Mosaic Virus (TMV). Both of these pathogens are present in most cannabis production locations
in Canada, though other viruses are likely to emerge as research continues in this sector.
HLVd is reported to cause stunting, increased lateral growth of branches, brittle stems, changes in the appearance of leaves, and a reduction in cannabinoid content of inflorescences. TMV can cause mosaic symptoms, as well as stunting and leaf curl.
Diseased plants should be destroyed and sanitation methods implemented to reduce spread of these mechanically transmitted pathogens through cuttings and handling of plants. Further research is needed to verify the distribution and potential damage caused by these pathogens, as well to develop long-term management approaches.

THE TASTE RACE: Light’s impact on crop aromatic and flavour profiles
Have you ever heard of the phrase, “Don’t judge cannabis by its odour?”
As consumers choose between purchases based on odours, colours and textures, the manipulation of light spectra could open up another door to richer aromatic and flavour profiles.
BY DR. DAVID HAWLEY
Of course not! Consumers absolutely judge cannabis and most other crops by their odour, colour, texture and—if free samples are available—taste.
For all the KPIs that growers attribute to their operational success and decision-making, accounting for sensory perception is rarely at the top. But a three-fold increase in cannabis production means little if it tastes like decades-old arugula.
Production gains and efficiencies are part and parcel of the growth model for every greenhouse. For those growing cannabis, strawberries, sweet tomatoes, basil
and other crops where taste is crucial to the consumer’s purchasing experience and the farm’s operational profitability, pursuing the perfect aromatic and flavour profile should be just as important as efficient yields.
In highly competitive industries where marketability is as crucial as volume, the taste race is on. And if plant genetics are the launch pad, then the right lighting strategy is the booster rocket.
Light spectra’s impact on secondary metabolite production and plant morphology is a wellknown and observable phenomenon in modern horticulture. As plants are introduced to more intense lighting treatments, their energy
and resources are diverted from primary metabolism—leaf, stem and root production—to secondary metabolism as a defense mechanism. The plant’s shift in response is ultimately what drives the production of secondary metabolites: terpenes, flavonoids and cannabinoids, among others. Yet the question remains: Which wavelengths should be introduced in a lighting strategy to yield richer aromatic and flavour profiles for a given cultivar?
Recent research from Fluence by OSRAM and Döhler examined the differences in taste and smell of sweet basil grown under far-red-enriched white light and blue/UV-enriched white light with normalized durations and intensities. In the ongoing study of plant responses to various light treatments, it’s an important step in understanding how spectral manipulation can create more complex or pronounced terpene profiles—the primary mix of constituent essential oils that determine taste and smell—in a range of crops.
Data from the sensory panel found, for instance, that blue/UV-enriched sweet basil yielded stronger elements
In a study conducted by Fluence by OSRAM and Döhler, panelists participating in a sensory study observed different tastes and smells of sweet basil grown in farred enriched light versus blue/UV-enriched light.
of citrus when smelled or eaten compared to the far-red-enriched option. Conversely, participants noted more earthy, grassy tastes and smells in farred-enriched sweet basil. The different lighting strategies also affected plant morphology. Plant height was greatest under the constant far-red treatment and more compact under the constant blue/ UV treatment, while plant height was average when exposed to end-of-day farred treatments.
This sensory data allows us to extrapolate some very interesting conclusions for growers striving to refine and perfect the taste and smell of their products to make them more marketable and, indeed, palatable.
Most importantly, it indicates that growers can manipulate light to refine their crops to yield or enhance a specific terpene profile. For example, a cannabis cultivator who grows sour diesel—a popular genetic strain with a signature
Biological control – utilizing a population of natural enemies to seasonally or permanently suppress pests – is not a new concept. The cottony cushion scale, which nearly destroyed the citrus industry of California, was controlled by an introduced predatory insect in the 1880s. Accelerated invasions by insects and spread of weedy nonnative plants in the last century have increased the need for the use of biological control. Use of carefully chosen natural enemies has become a major tool for the protection of natural ecosystems, biodiversity and agricultural and urban environments. $118.99 Item #1405145718
pungent citrus smell and taste—may want to introduce more blue/UV light into their broad-spectrum lighting strategy to encourage more production of the monoterpene limonene.
The same inferences can be made across a variety of crops and their corresponding terpene profiles. Betacaryophyllene, a sesquiterpene that yields a spicy, musky aroma and flavour and is a constituent terpene in black pepper, cloves, rosemary, hops, cannabis and other crops, similarly responded better to
blue/UV-enriched white light, potentially providing growers with the ability to enhance specific characteristics of their crops and maximize every plant’s potential. Other crops, like strawberries, are much more complex and require even more nuanced approaches. Early research into strawberries’ response to various light spectra, for instance, has shown that adding red light into a broad-spectrum strategy significantly increases flavour intensity, aroma and juiciness.
Research into the chemical responses to various light spectra that influence terpene production is still in its early stages, but the results so far are definitive in their own right. While many growers still justifiably rely on genetics to dictate plant quality—including aroma and taste—the next wave of cultivation innovation will ultimately be characterized by how environmental controls (the most crucial being light) can enhance the characteristics and traits already present in a given genetic profile. That’s especially true for the next wave of cannabis consumers whose purchasing behaviour is increasingly driven by how a product tastes and smells. Since secondary metabolite production—and the benefits it yields in marketability— comes at the expense of primary metabolism, which drives growth, striking a balance between the two is the next great challenge for cannabis growers.
The natural first step for cultivators is to establish their goals based on market demand. Some may opt to maximize their yields, while others may try to differentiate their product based on quality, nutrition, aroma and other sensory factors to maximize profits.
For cultivators in the latter category, the most effective solution is to tap into the growing body of research into lighting’s myriad of effects on cannabis growth, then apply that research to their own unique circumstances and environments. Practically, that could involve designating a small research space to test a few different cultivars under different spectra to find the right combinations of light and genetics to yield a flavour and aroma profile they can take to market.
In the industries where smell and flavour are just as important as production volume, that could mean a new opportunity to carve out a competitive advantage and deliver differentiated products that meet growing market demand.
David Hawley, PhD, leads the scientific research initiative at Fluence by OSRAM as the company’s principal scientist. His experience in controlled environment systems, horticultural lighting and the cannabis metabolome continuously drives the company’s lighting research to explore the interaction between light and life.

Canadian Greenhouse Conference wraps up multistream event
The Canadian Greenhouse Conference successfully held their second virtual event in October.
This year’s CGC expanded into a two-day online event with over 50 speaker sessions running on up to five concurrent streams, similar to the multiple rooms used during a live event.
But for those looking to revisit the content on-demand, it’s not over yet.
Although live portions of the event ran from Oct. 6 to 7, attendees and new registrants who chose the extended registration package can continue to access recordings of the presentations, on-demand sessions, as well as the New Product display. Recordings are available for 90 days following the event and new registrations continue to be accepted at this time, ending in early January 2022.
“We are pleased with the outcome of the 2021 virtual conference. The CGC mandate is to provide a forum for education and networking and we were happy with the level of engagement achieved across the various conference components and platforms. We have received positive feedback from our industry partners, attendees and speakers,” says organizers.
Along with the New Variety Showcase, the Research Poster Session and the Industry Partner Directory featured on the CGC website, their show guide offers valuable information, with reports from provincial greenhouse sectors across Canada as well as thoughts and hopes for 2022 shared by growers, suppliers and educators.
The CGC plans on returning to the Scotiabank Convention Centre in Niagara Falls, Ont. from Oct 5-6, 2022.
More details can be found on their website, canadiangreenhouseconference.com.

Crystal ball time
Well, it’s that time of year again. The weather has cooled and turned wet (here in Cascadia at least). Which means only two things: hockey is back and it’s fall season ‘Trade Show’ time. The Canadian Greenhouse Conference has come and gone for another year and early September saw a revamped CanWest Trade Show metamorphose into ‘Grow West Coast’ at a new outside location, right in the heart of the City of Surrey. As with many ‘new’ events, attendance was probably a little down compared to the ‘old’ event format, but of course, this was probably another casualty of the ongoing fallout of that dreaded five-letter word that I refuse to mention today. Despite this, the seminars were – as always – well worth attending.
Local horticulture guru Brian Minter reflected on a year-and-a-half of doing business during a pandemic and bravely grabbed hold of a crystal ball to consider what the future holds.1 After the initial shock of enforced lockdowns (to varying degrees) Brian noted that summer, fall and Christmas 2020 were bumper years for many garden centres and growers, with sales typically up 27 to 35 per cent. Summer 2021 (JuneAugust) saw a dip in sales from the previous year, but nonetheless were still up significantly over 2019. This has led into an extra-early start to the 2021 Christmas season, with many feeling that the season began straight after Remembrance Day. Brian forecasts 2022 to be similar to 2021 or even better, with many young people taking up gardening. In other words, don’t be short on
they want to get more organic supplies. Against all these demands for products, the industry faces significant supply challenges. This is not news now, of course. Whether it be for actual goods (soil, pots, lawn seed, roses in particular according to Brian) or just getting goods shipped (lack of truck drivers if you’re in the UK, lack of shipping containers if you are everywhere else), the end result is the same: production difficulties for growers to prepare enough inventory for spring sales. One grower at Grow West Coast was telling me his pot supplier was pleased to confirm pot order delivery for June. Trouble is, they were supposed to come for potting season in February. What will this look like when growers are talking to the pandemic gardening converts next spring?
Even if growers can produce what new customers are craving at the start of the new season, will they be able to pass on the extra production costs they’re facing this year? Many manufactured goods are simply costing more (supply and demand as factories that closed have yet to get back to pre-pandemic output levels, if they open at all), plants are costing more, and shipping is definitely costing more. A local large producer of greenhouse peppers was saying his budget for supplies had gone up 31 per cent in September compared to what he’d planned even just one month earlier, due solely to freight costs. 2022 is going to be ‘interesting.’
...plants are costing more and shipping is definitely costing more.
inventory. Hmm. Easier said than done. Brian also highlighted a number of consumer trends that he has noticed from business at his own garden centre. These include increased concern for bees and pollinators (especially from the young folk); gardens going up (literally, physical vertical gardens to optimize limited space in townhome gardens); desire for healing plants, herbs, edibles; designing and installing outdoor rooms; and customer concern for the environment in general, and in particular buyers looking to get away from single-use plastic pots. New gardeners also believe that they don’t need a large space to enjoy a garden, they seem to love ‘retro plants’ (ferns and indoor plants that your grandmother use to have such as Pothos, African Violets) and
Being the creative, industrious, resourceful bunch that they are, I’ve no doubt that growers will find ways to survive and indeed thrive. There have always been challenges to overcome, and the strongest and fittest have always overcome and grown stronger and fitter. It would sure just be nice to be in ‘control’ of one’s own challenges for once, rather than having them imposed. This all said, let’s harken to Brian Minter’s forecasts that 2022 promises to be a great year for the horticulture industry. Merry Christmas!

LED BY SCIENCE
MEETING CONSUMER DEMAND WITH AN ENHANCED FLUENCE LIGHTING STRATEGY
Glenwood Valley Farms is located in British Columbia and is one of the most prominent North American greenhouse farmers. Growing and distributing produce year-round to local grocers and retailers through its strategic partnerships with BC Hot House, a division of The Star Group. With a greenhouse standing at 15 feet tall, existing facility and environmental constraints forced founder Herb Schlacht to explore alternatives to traditional HPS fixtures, which he realized were detrimental to crop growth, workplace conditions and overall operations and profitability. Combined with a desire to produce larger, healthier, more flavorful crops, Glenwood turned to Fluence and the VYPR series to solve both challenges with an LED implementation. With assistance from Fluence, its products and horticulture expertise, Schlacht and the Glenwood team achieved what every grower strives for: improving operational efficiency and conditions while enhancing top-line production performance.
