Message from the President

BCLNA Board Highlights

What have you got to give?

Monday, April 20, 2009

I am inspired. I just read an article in the Vancouver Sun about Alison Lawton’s “NewGen” philanthropic activities. According to the article, she is a successful young entrepreneur and multi-millionaire who feels that she can facilitate more change as an investor in non-profits, than as an activist. She works on a global scale amongst the rich and influential of the world in an effort to reduce world poverty. Ms Lawton currently funds, among other things, journalistic activities with students that will raise the awareness of worldwide humanitarian and environmental crises. But

she began her giving in Uganda creating “Uganda Rising,” a documentary about the plight of the Acholi people whose children were being abducted by rebel soldiers. When exhausted after spending a million dollars and three years of her life on the project, and struggling with how to continue and publicize the work, she met with the Dalai Lama who told her to “stop worrying and work from a place in your heart”. That’s what got me.

the Growing Hearts “Sunny Hill” project, last year. Others have gone abroad to help children. The board is having discussions around how to expand on this type of involvement. Bring us ideas and commitments. Think big. We can’t all be involved hands-on. We all have varying degrees of available resources. But collectively, we all have the ability to give on some level for the betterment of our businesses, our families, our communities and the rest of the world.

Brown Garden Snail Creeps Across Border The regulated pest, European Brown Garden Snail (Helix aspersa Mueller), has again been found in shipments of plant material originating from California. Authorities report that a California Department of Agriculture advisory requiring inspection for this destructive pest prior to export had been unexpectedly dropped, resulting in a number of interceptions by the CFIA.

Says Ken Wong of the CFIA, “California has been requested to re-institute the snail free holding area requirements to ensure nursery stock is entirely free of the pest.” Canadian importers can expect a 30-day delay in some shipments while they are quarantined and inspected. Wong adds that it will take the state about six months to get compliance agreements re-implemented for all nurseries shipping nursery stock to Canada. In the meantime, they will put a priority on getting Californian nurseries that have already shipped infested product in compliance by mid-June.

About the Vancouver Convention Centre Green Roof Andrea Martinello, Marketing Manager N.A.T.S. Nursery Ltd. The spectacular new Vancouver Convention Centre is open. Its crowning feature is a living roof composed of Pacific Northwest native grasses, perennials, sedums and bulbs. N.A.T.S. Nursery is excited and proud to be part of such a large-scale project.

BCLNA at the Vancouver Convention Centre

BCLNA Shines at VCC Opening with Member Support It was late in February when the CanWest Hort Show received an invitation to be one of 10 tradeshow displays featured at the Vancouver Convention Centre’s grand opening. Honoured and overwhelmed with excitement, staff tried to figure out how to make it happen. While it presented a great opportunity for CanWest’s exhibitors, it presented an even greater opportunity to promote the industry to hundreds of VIPs and thousands of Vancouverites expected to tour the facility. One particular CanWest exhibitor and long time BCLNA member, Don Fraser of Northwest Landscape Supply Ltd., was especially intrigued with the opportunity and offered to spearhead the project. Within three weeks Fraser, with Bill Hardy and the Northwest team plus a tremendous contingent from so many CanWest exhibitors and BCLNA members, his vision of a display that would capture the beauty of the landscape trade and the heart of nursery growers was realized. And wow, did this 120-foot by 60-foot display make a presence! About 2,500 local, national and international VIPs attended the official grand opening on April 3. The facility was then opened to the public for two days following, drawing more than 68,000 visitors.

Everyone who checked out the facility agreed that there was a buzz in the air. The architecture, green roof, ocean views and mountain vistas were amazing, and the BCLNA garden was breathtaking. CanWest and BCLNA were fortunate to be part of this historical event. A sincere thank-you goes out to everyone who contributed. From plants and trees, to stone and mulch, to the transportation that went along with it: all is very much appreciated. And to the fantastic crews who brought time, talent and tools to build the display—thank you. Our members generously donated thousands of dollars in supplies and person-hours! Our gratitude again to Don Fraser for his vision and enthusiasm: Don, you brought the green industry to the centre stage of BC’s biggest public relations event of the year!

Nursery Ltd. Think Green Landscaping urban-escapes Watermark Gardens Photo top-right: LiveRoof® pre-vegetated modular trays like this one comprise the green roof at the newly expanded Vancouver Convention Centre. Photo below: Approximately six acres of seeds, bulbs, and plugs were produced by N.A.T.S. Nursery to complete Vancouver’s most impressive green roof project.

While green roofs are definitely not new, they are not in widespread use in North America. This is changing. An increasing number of construction projects are including green roofs and living walls in their plans. And even though the Vancouver Convention Centre’s roof is an expansive six acres, it shares the same considerations that any green roof project would have. To properly install and maintain a well-functioning green roof one must take into account variables such as function of the roof, size, exposure, soil depth and project budget. The particular conditions at each site will dictate the species of plants that will thrive—and plant material is the engine that drives a green roof’s viability. Green roofs usually fall into two categories: bulk-laid or modular systems. Bulk-laid systems are composed of multiple layers. These include waterproofing, drainage, root barrier, engineered substrate and planting layers, the last of which are either comprised of plugs planted in place, cuttings scattered over top, or seeded material. These roofs typically take two to three years to grow to complete coverage, and require some extra maintenance during the initial grow-in phase. This is a great option for designers who wish to create unusual patterns or a certain look. LiveRoof® pre-vegetated modular systems are grown at the nursery and are delivered to the job site fully rooted, and with better than 95% coverage. This has the benefit of providing a “ribbon-cutting ready” green roof, immediately after installation. The modular trays are laid directly on a slip-sheet over the waterproof membrane. After much research into available systems, the team at N.A.T.S. selected the LiveRoof® pre-vegetated modular system as the best, and has become the licensed distributor of this product for BC and Washington State. A project of such an enormous scale as the Vancouver Convention Centre expansion requires a lot of planning and testing. N.A.T.S. grew the selected species for trial plantings in roof mock-ups. Much was learned about the way the chosen plants would interact on the roof, so the list could be adjusted ahead of time to remove species which were deemed to be too aggressive, poor performers or too tall. Plug trials were run ahead of time at the nursery, designed to test how the plants responded to the specially engineered substrate, determine the actual growth rates of the plants, and to expose any other growing issues. We started organizing seed supplies as early as 2005; the project plugs were sown in the summer of 2007 and the first shipments were made in the spring of 2008, with the last shipment leaving just this past spring. It was a very longterm project, with a huge amount of effort involved over several years. The result? The roof is spectacular both in scale and appearance. A recent decision to add apiaries for bees was truly unique and a real nod towards the ecological intent of the roof. For more about green roof systems, please contact N.A.T.S.

David Woodske, Industry Specialist BCMAL Effectiveness of Pasteurized Poultry Litter as a Partial Substitute for CRF in the Production of Contai2-grown Ornamental Plants (HortTechnology 18(4):671-676) – The goal was to determine if pasteurized poultry litter (PPL) could be used to reduce the amount of controlled release fertilizer (CRF) required for the production of container-grown tropical plants (areca palm, downy jasmine, and Chinese hibiscus).The four fertilizer treatments included the medium rate of Nutricote alone and, in combination with PPL (31.5 lbs/yard3) or a micronutrient blend, and the high rate of Nutricote.The addition of PPL significantly increased the initial substrate pH and reduced substrate porosity. PPL also provided significant amounts of N, P, K, Mn, and Zn, but they were released primarily during the first few weeks after potting. Plant response to PPL amendment differed. Downy jasmine and Chinese hibiscus grew better and areca palm performed poorly with PPL amendment.

Secondary Macro- and Microelements in Sphagnum Peatbased Substrates Amended with Parboiled Fresh Rice Hulls (PBH) or Perlite (HortTechnology 18(4):650-655) – The 10 substrates consisted of peat amended with 20%, 30%, 40%, 50%, or 60% (by volume) PBH or perlite. Substrate samples were collected for nutrient analysis 0, 4, and 8 weeks after mixing. For all 10 substrates the concentration of B, Mo, Cu, Mg, and Ca were within recommended ranges for greenhouse crops, and Zn, Fe, and S were within maximum recommended levels.Two significant differences between the amendments were PBH contains a high level of Mn and perlite contains a high level of Zn.The concentration of Mn in media amended with more than 50% PBH exceeded recommended levels for greenhouse crops.The authors recommend growers maintain optimal pH and limit PBH content to 50% or lower for crops sensitive to Mn toxicity.

Send us your wish list or job and we will send you a quote – phone, fax or email

A proven media magnet, BCLNA’s Landscape Awards of Excellence are a sure-fire way for landscape professionals to get great publicity. Over the past few years, the Awards program has been acknowledged by an increasing number of media agencies, news columnists, and magazine editors, and better quality digital photos mean that nearly all editorials are accompanied by the landscapers’ own project photos! Now is the time to start planning your Landscape Award of Excellence entry, so that you too can benefit from this invaluable press coverage. But take note: your winning projects have raised the bar! Awards entries have set a greater standard of workmanship than ever before, and awards have been granted in record numbers, so the points system on which they are graded has received an

upward adjustment. Additionally, maintenance category entrants will need to submit photos of the site showing two seasons of maintenance or more. So get out into your landscapes and begin taking photos of your projects this spring, and consider using a professional to shoot your landscape at its peak: the better your project’s scope is depicted, the better judges can assess its merits and the more likely that your team will find its winning projects in a magazine spread. Mark your calendar: all entries are due on August 5, 2009 (no extensions, no exceptions). The full entry package will be available at the end of this month; contact Annika Ingram for your application package at (604) 574-7772 or aingram@

How can you benefit from this expertise? Tigwell visits a site for three to four hours, awarding scores and taking photographs to illustrate your centre’s report (up to about 100 photos, depending on the size of the centre). The consultant will provide feedback on what has been seen, and what can be improved; your staff can be involved in this discussion if you wish. The inspection report will be completed and e-mailed to you, followed by a CD with photographs

and copy of the report by mail. This independent, unbiased view gives you a snapshot of how your garden centre appears to your customers, and how it might be improved, both in terms of retailing and profitability. It also provides a discussion on the direction of garden retailing, with particular focus on your centre, and can be turned into a local publicity opportunity. Optional future inspections help you to measure yourself and set standards from year to year. The inspections will be carried out in June and July 2009, but there are only 18 spaces available, so book your place now. You must be a member of BCLNA to participate. Please note, your registration is not guaranteed until a minimum number of inspections in your area is met. For more information or to register, contact Rebecca at CNLA: or 1-866-383-4711.

1. Flaming is an effective tool to manage weeds on paved surfaces and other non-crop areas. Many practitioners in British Columbia tried flaming in the 1990s, only to abandon the practice because associated labour costs are higher than traditional herbicide spraying. Spraying, however, is no longer an option for many landscape managers in municipalities, where new bylaws restrict the use of pesticides. It is time for our industry to revisit this practice and conduct applied research on the tools commercially available. 2. Pictured here is a large flamer at work at in Denmark. In many cities of Europe, the use of herbicides is prohibited for weed control on hard surfaces. Some bans have been in place for 10 to 15 years, which has forced intensive research on non-pesticide methods. Flame weeding is reported to be “the most commonly applied thermal weed control on hard surfaces” and in regular use in countries such as Denmark and Sweden (Weed Research, 2004). Commercial equipment is readily available, including hand-pushed shielded flamers for use on small areas. Photo: P. Kristoffersen, Denmark.

3. A BC farmer is “flaming” weeds in his apple orchard. Excellent research comes from organic farming, where weed management is difficult because herbicides are not allowed. What is important is the intensity of the heat by unit area: a hot flame can be applied for a very short time, while a warm flame must be applied for a longer time.

Swing Into Spring

Exposure to heat of 55 to 95 degrees Celsius for 0.1 second is enough to kill leaf tissue – just one tenth of a second over the weed! No need to stand there for minutes!

4. The fingerprint test is a good way to verify the effectiveness of any heat treatment, including flaming. Heat triggers denaturation of a plant’s cellular proteins, leading to cell rupture and desiccation. After flaming, take a weed leaf and press hard with your thumb - if the finger mark stays imprinted, the leaf has suffered irreparable damage and will die. A common mistake is to burn the weed to a black charcoal – it is not necessary, except for the psychological satisfaction of seeing a dead weed! Photo: Dr. S. Knezevic, University of Nebraska.

5. Grasses are very tolerant to flaming, because their growing point is underground and protected from the treatment. This is also true of most perennial broadleaves and some annuals such as Shepherd’s purse and scentless chamomile. The above-ground portion may be killed, but these weeds will re-grow from the meristems and repeated flaming is needed. On the other hand, weeds with unprotected growing points and thin leaves are easy to control with flaming, such as Lamb’s-quarters, groundsel and chickweed.

6. Another non-chemical method is to pour boiling water on target weeds. It is a good suggestion for residential customers looking for organic methods.

It is more effective on seedlings and droughtstressed plants and less effective on wet weeds, and must be repeated for difficult-to-control weeds. Another consideration: the water must be near the boiling point, so reduce the time between boiling and walking to the target weed.

7. Acetic acid is registered as a herbicide in commercial and domestic formulations. The commercial formulation is 20%, stronger than household vinegar (5%). Acetic acid is an “excluded” pesticide in the provincial legislation, meaning there is no need for a license or certificate to buy and apply, and most municipal pesticide bylaws allow its use. It is a contact herbicide that controls only the above-ground portion of the weed. Remember that using acetic acid instead of glyphosate is not “IPM”: it is strictly product replacement. Integrated Pest Management requires a thorough understanding of the plants managed, a strong emphasis on prevention methods, and control methods that combine non-chemical with chemical.

8. This commercial hand-held machine uses infrared radiation. Propane gas burning at high temperatures heats a ceramic surface, which then radiates heat to the target weed. The method is less effective than flaming because of lower heat transfer to the weed. However, it does not have an open flame, and is thus quite appropriate for small residential sites, windy locations, or other situations where flaming cannot be used (be careful not to start a fire in the mulch of the shrub bed!).
