➾ F R OM THE PRESIDEN T

The Art and Science of Evolving our Roots A few months ago, in our home garden, we were fortunate enough to host a handful of plein air artists practicing their craft. “En plein air” is a French expression which means “in the open air” and is used to describe the act of painting outdoors.

Heidi Heiland

i immediately related to these artists as I also prefer to practice my craft outside, versus at my computer or drawing board. However, my palette of colors is the wide array of plant materials with which we make brush strokes on the earth. These plein air artisans and I shared our experiences of the occasions when we felt “in flow” and our talents seemed to percolate from us as if we were simply the conduit of some superior design mastery. Truly a gift from above!

While the desire to be “in flow” or to bring our best efforts consistently to our clients is most certainly a goal, the reality of life is that many times we are forced to perform our art in less than ideal situations. Too many times the external pressures of deadlines, weather, product availability and client expectations loom in our creative spaces. I challenge myself to find my flow state, but am not always successful. However, when pushed to the limit, when I seem to be struggling or hitting a wall, I hone my craft even further. I believe without reaching, stretching, or exploring we may not gain new insight.

I believe landscape designers may be tested more than other artists since typically other canvases are static, but our piece is an ever-evolving landscape of living art.

A well-placed accent in our landscapes can embellish any presentation and evoke a thoughtful response.

Whether we are trying to illicit calm, curiosity or mere enjoyment, our creative skill is necessary to connect our clients to their land. Even more important than the visual appeal of our outdoor environments is the functional system of our designs. Regenerative landscapes with whole-system strategies that consider soil fertility, water management, biomass inputs, pollinator habitat, educational opportunities, and available

resources can be achieved along with the aesthetics.

The art and science of growing plants do not have to be mutually exclusive. This year my son and I explored how we could best achieve a permaculture design in our own yard that is also sale-able to our high-end clients.

We are thrilled with the results of harvesting a diverse crop of annual and perennial edibles while managing the site with a closed loop intention. Additionally the beauty has piqued interest and is educating our neighborhood, community and tour groups that come

through. Sharing information over the garden fence is how our industry began!

I am extremely grateful that I am paid for my art and have this unique platform to assist in shifting our natural world back into indigenous wisdom. I am also thankful that my mom acquired one of the plein air paintings for my birthday so that I can stay connected to my gardens with this artistic reminder. This piece cues my memory of flow state, of sharing with others outside, of favorite foliage and blooms. The people– plant connection is an important priority that I am not sure we focus on enough as a culture. Our art is truly a gift from above!

➾ S OCIAL MEDIA

The Social Marketing Process ©Jeff Korhan

A

dvertising was synonymous with marketing during the early days of television, a medium that was perfect for promoting products to the masses. Those were the glory days of Madison Avenue, when perception was everything. “Sell the sizzle, not the steak” was one popular catchphrase from this era that marketed excitement, glamour and intrigue. It turned out that more than a few expectations were unfulfilled because the products or services did not meet marketing’s promise. As a result, even though product and service excellence was once the most reliable method for achieving and sustaining business success, it’s now expected. This creates new marketing challenges and opportunities, but fortunately we now have flexible media channels for capably responding to both. #1 — Marketing Today Starts with Attractive Content

Buyers today have access to abundant information for quickly and easily eliminating businesses that do not meet expected standards of excellence. As a result, any use of marketing to address quality is usually a distraction at best. To make your business attractive today you have to create helpful media content that answers questions and solves relevant problems. This is generally known as content marketing, and it is so integral to social media marketing success that many consider them to be one and the same.

Content that educates, informs or entertains makes a business attractive. It helps buyers to better know and relate to the people within the business, thereby giving them reasons for developing a relationship with it. However you position it, your content marketing should be designed to create value. Viewed another way, it actually adds value to the product and service, and that makes it a differentiator. #2 — Social Media Engages Interested Buyers

If the goal of content marketing is attraction, then the next logical step is engagement with interested buyers. Apparently, this is something that many marketers do not understand. They imagine their social media channels will somehow magically generate new business, going straight from attraction to a sale. While that may occasionally be possible, it is unlikely — much like progressing directly to marriage after a first date. People need time to get to know, like and ultimately trust your business, and that is only going to happen if you are having conversations with them. You have to monitor your social media and respond to inquiries as you would with any other communication channels.

The reality is social media marketing works on its own time, with some buyers requiring more information and attention before they learn to trust your business. Just know those that engage on social media are very likely in a greater state of readiness, which is all the more reason for giving them your full attention. For the remaining silent majority, keep sharing great content that helps them do more of what they want to do, which is presumably getting more enjoyment out of their outdoor environment.

To make your business attractive today you have to create helpful media content that answers questions and solves relevant problems. This is generally known as content marketing, and it is so integral to social media marketing success that many consider them to be one and the same. #3 — Sales Converts Trust into Profitable Outcomes

The truth is that social media rarely sells, but instead prepares buyers for the sales process that ideally is designed to seamlessly integrate with it. This is often a method the business founders intuitively developed to successfully get and keep those earliest customers. That process has to be refined to make it as efficient as possible, so it can adapt to market changes, such as the influences of social media. For example, when I started my landscape business in the late 1980’s, most leads were either personal referrals or telephone inquiries directly to the office. It was easy to manage.

Today, every business with a website or social media presence is developing relationships with people across multiple channels, and this is happening before it is even aware of their existence. This is why everyone on your team should thoroughly understand the next steps for engaging with those educated buyers when the time comes.

That first response today is so important, because unlike the days before the Internet, more than 50% of the decision-making process is complete before your business has the opportunity to personally engage. What follows next should be a high value response that gives the buyer confidence for proceeding further. That could be some form of personal, authentic communication, such as sharing a relevant story. The point is that in a world where buyers are better educated and informed, every team member that has any contact october 15

MNLA CERTIFICATION SSIO

MNLA CERTIFICATION PROVES COMMITMENT AND PROFESSIONALISM. The MNLA Certified Professional status benefits individuals by instilling pride and confidence, bringing greater value to the nursery and landscape industry, demonstrating commitment to the nursery and landscape industry, and enhancing employability within the industry. MNLA member businesses that employ certified professionals enhance their own professional image, increase customer recognition and respect, provide a consumer marketing tool, and offer an additional tool for employee motivation, evaluation, and advancement.

In order to become certified, one must pass a general horticulture exam and then one of the specialization exams: Garden Center, Grower, or Landscape. The exam is given in an electronic format with integrated photos and videos. Applicants take the exam at a computer station and receive the results immediately after completing the exam.

October is an excellent time to begin reviewing the study materials to prepare yourself to take the exam in 2016. Visit www.mnla.biz for certification information and to download chapters of the MNLA certification manual.

with customers has to be too, regardless of whether they are in sales, marketing or production.

Many buyers are already “sold” when they reach out to your business, they just need confirmation of their present understanding and answers to a few questions, such as what happens next, and what happens after that, and so on. This is the magic of a welldesigned sales process, and it can be a deal maker or breaker.

What will reliably handle most inquiries is having the entire sales and marketing process organized, with the key steps named and described so that everyone can explain how it works using essentially the same language. This is vital for giving prospective customers the confidence for taking the leap to work with your business.

While this takes time to initially develop, it is much easier once you learn why every business needs a visible, named and branded process, and a behind-the-scenes process that supports it every step of the way.

If this sounds like work, it is. However, I promise you this will dramatically reduce your sales and marketing costs, while concurrently increasing the rate for closing new business, not to mention differentiating your business for social media savvy buyers.

You’ll get it all at my two sessions at the Northern Green Expo in January.

I’ll see you there.

EN THE CRACKS Crevice gardens, a specialized type of rock garden, are a great way to feature distinctive plants.

Note from editor: This article originally appeared in Digger magazine, which is published by the Oregon Association of Nurseries (www.

DiggerMagazine.com). Written by Loree Bohl for Oregon gardeners, it contains Oregon-based plants, advice, and locations. However, it nevertheless covers important information for a Minnesota-based professional audience. The concept of crevice gardening will prove to be of interest to a wide array of MNLA members, with applications large and small for Minnesota plant and landscaping sales.

Crevice gardens can showcase a wide variety of plants in narrow spaces.

T

wo simple questions asked by Kenton J. Seth illustrate the idea behind the crevice garden: “Do you have weeds in the cracks of your sidewalk?” and “Do those plants grow better than some plants in the garden?” Seth, owner of Paintbrush Gardens in Grand Junction, Colorado, further explained crevice gardening as “a style of rock gardening which is essentially paving your raised bed with rocks, and then planting plants in those tiny little spaces.”

Crevice gardening formally began in the Czech Republic before the fall of the Iron Curtain, according to Mike Kintgen, curator of the Alpine Collection at the Denver Botanic Gardens. “Czech gardeners have some of the most amazing and beautiful crevice gardens filled with very choice alpine plant material,” Kintgen said. “They are some of the most devoted and esteemed rock gardeners in the world.”

Zdenĕk Zvolánek, self-described “missionary for crevice rock gardening” and internationally recognized expert in the field, traces the genesis of the crevice garden back even farther. “There was a construction with ‘vertical stratification’ in England made for the Chelsea [Flower] Show in 1923 by Symons-Jeune. It was very nice, brave, but crevices there were not planted, so it was only [a] romantic and decorative effect.”

Zvolánek and another Czech, botanist Josef Halda, are credited with perfecting this style of gardening and bringing it to North America.

Zvolánek, however, also credits American plantsman and author H. Lincoln Foster; his writings inspired the Czechs, who “discovered quickly all the advantages of this modern kind of construction.”

In the United States, the current epicenter of crevice gardening is Colorado. The Denver Botanic Gardens features several crevice gardens. Kintgen, who has been involved with the garden since the age of 11 when he began volunteering there, explained that three crevice gardens are nestled within the Rock Alpine Garden. “One large, south-facing xeric for steppe flora, one east and north-facing for alpines, and one partially shady, north-facing for Primula, Saxifraga and other cool-loving, shade-needing (in Colorado) species.”

The crevice advantage

Home gardeners in Denver and beyond are discovering this style of planting. It allows them to successfully grow plants they had previously failed at.

Another benefit, as Seth pointed out, is one sure to please gardeners frustrated with shrinking space: the peaks and valleys of a crevice

garden actually increase the surface area of the garden. There’s more room available for plants, and the topography creates distinct microclimates, such as shady spots, where none previously existed.

Additionally, the plants are smaller in size. In the space where only two or three shrubs might grow, 20 or 30 of these pocket-sized gems can flourish.

Like those cracks in the sidewalk, the crevice provides an ideal microclimate — a cool, yet moist place for the plant’s roots to grow.

Available water is quickly funneled down along the rocks, which encourages deeper root growth, while the top of the plant stays dry.

Rock gardening has a reputation for demanding excessive amounts of attention and care, but crevice gardening is often referred to as “the lazy man’s rock garden.” Once the crevice garden is built, little in the way of maintenance is required.

Building a crevice garden requires strength and patience, and there’s no rushing that which must be done right. “Take time to do the stone work correctly,” Kintgen advised. “A well-made crevice garden is an investment in time; however, it will last for decades and is capable of growing plants that will not grow anywhere else in

the garden. A well-made crevice garden is a work of art, beautiful throughout the seasons.”

Creating the crevices

Seth estimated that 50–75 percent of his time is spent building crevice gardens, but it’s an investment well spent. He credited these gardens for making xeriscaping much more interesting.

When choosing the location for a new crevice garden, a site with little competition from nearby trees is best. Tree roots may grow into the garden and compete with the plants for available moisture, and falling leaves can create a maintenance nightmare.

The crevice garden style is one that works on any scale, from an entire garden to a small trough. “Don’t skimp on rock! It takes way more rock to build a crevice garden than a regular rock garden.”

Kintgen said. “If you find yourself on a budget, build a small crevice garden that can be added onto in time.”

Seth starts work with the outside edge — the foundation stones — for support and boundary development. He places big stones along the ends, then smaller stones in the middle on a mound of material, october 15

typically sand. This big-to-small arrangement is the opposite of how the finished garden looks, where the middle rocks appear to be taller.

As he builds the garden, he keeps the rock strata aligned, so the look stays organized and natural: he described the visual effect as “one stone broken into pieces.” For inspiration, he looks to natural rock formations.

The typical foundation on which the rocks are placed is builder’s sand or concrete sand — not sand meant for a kid’s sandbox. A 50/50 mix of sand and gravel with no organic material can also be used. “Sand has texture, lots of oxygen and humidity in the air spaces. Humidity in soil is good for the roots,” Seth explained. This mix provides excellent drainage and also protects the rocks from frost heave in the winter. A top dressing of gravel keeps the sand from washing away.

The rocks must be buried deep enough that they won’t tip over.

“You’re burying 90 percent of the rock cash you spend,” Seth lamented. While round stones aren’t traditional, they can be used.

Recycled concrete (aka urbanite) is another option.

“Make sure the rocks touch one another and actually lock one another into place,” Kintgen said. “Planting pockets are created between the stones by leaving small spaces between layers of stone.”

The width of the space between rock layers is key in creating a true crevice garden: one inch is the target normally mentioned, although larger plants may require wider spacing. Broad crevices risk not creating that ideal microclimate, and drainage will also suffer.

When asked about the aesthetic of a successful crevice garden, Zvolánek said some constructions fail because they are too flat and uniform, while others have “crevices imitating canyons, where the surface of substrates is not level with the tops of the stones.”

Future maintenance is also a consideration during the building phase. “Make sure to leave access points and places to step in the garden if it is large. One needs to be able to reach every nook and cranny in the garden to weed and plant,” Kintgen cautioned.

When it’s finally time to plant, Seth shocks many by bare-rooting the plants before packing them into small planting pockets. He goes so far as to wash the roots free of soil and then uses a Hori-Hori, butter knife or even chopsticks to carefully work the delicate roots down into the sand. By removing the existing soil, he’s forcing the roots to grow down into the layers, along and beneath the rocks.

Plants for crevices

“Crevice gardens were originally created to grow alpines in an environment that resembles, both to the eye and functionally, their native habitats,” Kintgen said. “One could grow whatever they please in a crevice garden. Larger plants will cover much of the stonework. Smaller plants such as choice cacti, dwarf shrubby plants, and alpines are the best options.”

Truls Jensen is co-owner of Wild Ginger Farm in Beavercreek, Oregon, a retail nursery specializing in rock garden, alpine and

woodland plants from around the world. Jensen has built several crevice gardens over the years, including a few smaller, trough versions.

He reported our native Penstemon are particularly well adapted to life in a crevice garden, as are Lewisia, Primula and Campanula.

Jensen has been known to anchor smaller, more delicate plants in place with groupings of Jovibarba. These tiny succulents look like Sempervivum but instead of expanding via offsets on stollons, they produce new plants attached directly to the mother plant, staying in tight clumps that fit within the crevice. J. heuffelii is a particularly attractive choice, with shades of red and green. J. hirta and J. sobolifera both produce off-sets that roll off the mother plant to form new plants, a habit which has earned them the common name “rollers.”

Jensen grows several Saxifraga, including S. x anglica ‘Cranbourne’ — “an early flowering cushion saxifrage with small, bright green foliage and large pink flowers held just above the cushion.” S. x boydii ‘Cherrytrees’ is a dwarf plant with clear yellow flowers. Saxifraga means “rock breaker” in Latin, and these diminutive plants often grow in rock crevices in their native alpine habitats.

Scleranthus uniflorus, a New Zealand native, and Azorella trifurcata ‘Nana’ from Chile form dense mounding cushions that fill empty crevices with a soil-stabilizing green carpet.

With their compact rosettes and bright flowers, Lewisia is a musthave plant for many crevice gardeners. Most Lewisia do exceedingly

well in a crevice garden, particularly L. longipetala ‘Little Mango’, ‘Little Peach’ and ‘Little Plum’ — all offered by Little Prince of Oregon Nursery, a wholesale nursery in Aurora, Oregon, specializing in ground covers, ornamental grasses, ferns, native plants and succulents.

Mark Leichty, director of business development at Little Prince, also suggested Armeria maritima, a compact, low-growing plant with grass-like foliage and small magenta flowers. He also recommended A. maritima ‘Alba’ for white blooms and ‘Nifty Thrifty’ for bright pink blooms.

Finally, the challenging Castilleja miniata, or Indian paintbrush, just might be the crevice garden plant mentioned with the greatest reverence. As difficult to find as it is to grow successfully, both Champoeg Nursery in Aurora, Oregon, and Sevenoaks Native Nursery in Albany, Oregon, grow limited quantities.

Over the years, I have developed close working relationships with many different departments and have good rapport with those higher up in the food chain as well as those farther down. All of the associations with the higher-ups began haltingly because I was a newcomer who asked a ton of questions. I was unrelenting (and probably a pest). As I learned who had the most patience, I would ask more and more questions of them. At our last GILI session I asked how being in production fit into customer service and the answer was, “You have customers — they are just within the company.” I decided I wanted to make it my goal to be that person with the most patience, so people could pick my brain for information and advice like those people I used to pester. I started making it my business to make sure they had everything they needed from me. I talk to shipping every morning to see how they need to be staffed for the

I talk to inventory every morning to alert them to new planting or moves. I sincerely ask everyone “Is there anything I can do for you?” At first I got looks like they didn’t know if I was serious. After the second day, they would stop, think, and tell me “no” or “yes, there is this one thing…”

I ask those with whom I work closely the same question several times every day. It helps me decipher who is doing well, who may need guidance, and who might need some hands-on help and elbow grease.

Now, I get other people asking me the same question: “Is there anything I can do for you?” Holy Cow! Sometimes, that one question opens up Pandora’s Box; sometimes it closes the Box before it is barely open. I will be forever grateful to the people I used to pester. They are the ones who were living examples of leadership and great customer service.

If looking for a quick-blooming vigorous begonia, it’s hard to beat BIG Red with Green Leaf. Although the fire-engine bright crimson red flowers are exceptional, the combination with the glossy green foliage is outstanding. BIG Red with Green Leaf grows well in partial shade, grows to a height of about 20", and is perfect for a mass planting.

 Begonia x benariensis BIG® Red with Green Leaf —

nnual flowers are evaluated on unique characteristics, exceptional performance, color and vigor under regional conditions.

Only the highest rating cultivars earn the distinction of a Top Ten Performing Annual. The goal of evaluating this vast array of cultivars is to develop recommendations for Minnesota.

Even though the annual flowers are under evaluation, the plants are placed into an aesthetically pleasing design, allowing visitors to enjoy the beauty of the garden. All flowers are labeled, allowing visitors to take note of top performing cultivars under regional conditions. The Horticulture Display Garden is open daily from dawn until dusk; admission is free.

NURSERY CERTIFICATION MULTI-STATE GROUP INSPECTION & SYSTEMS APPROACH

Josh Plunkett

(MDA, Plant Protection) Nursery & Export Unit

THE INSPECTION AND CERTIFICATION OF NURSERY STOCK is becoming increasingly more complex for the industry and regulatory agencies due to broader and faster shipping patterns and the expanding number of regulated pests. The National Plant Board (NPB) and regional chapters of the Horticultural Inspection Society (HIS) are responding to this challenge by piloting a new process for incorporating a Systems Approach to Nursery Stock Certification (SANC). The goal of SANC is to: “Develop, promote and implement a risk-based nursery and greenhouse certification system utilizing existing state authorities and programs to enhance uniformity, increase efficiency and reduce pest distribution.” Another way to state that is to balance and focus resources to better manage high risk commodities such as nursery stock.

In the long term, realized benefits of SANC will include: a reduction in pest risk, cost efficiencies, increased interaction with industry staff and regulators, and uniformity among state programs. With these goals in mind, nursery inspectors from seven central states

attended the Horticultural Inspection Society (HIS) multi-state group inspection hosted by the Indiana Department of Natural Resources.

This unique opportunity to share inspection challenges, as well as tips, and observe plant pests not commonly encountered in Minnesota was a truly valuable experience.

HIS members attended field inspection at two nurseries in the Indianapolis area. In addition to regional inspectors, Purdue Entomologist Dr. Cliff Sadof, and Purdue Plant Pathologist Dr. Gail Rhule provided valuable expertise and advice for scouting and diagnosing Midwestern pests and pathogens.

Inspection techniques, plant pest identification and treatment methods were discussed and practiced as a group. Additional SANC training helped inspectors identify critical control points (CCPs) and develop practical means of reducing pest risks.

To start the group inspection, Ken Rauscher from the National Plant Board led a training interview at the first

nursery. The discussion focused on control points such as: plants, potting media, storage, sanitation, production practices, pest and disease scouting, employee training, record keeping and even cull piles.

Those are a few of the identified SANC targets or “choke points� in plant production where best management practices can effectively control plant pests and diseases.

The first part of the discussion focused on plants and propagation, which are the most important part of the review process for nursery inspectors. Incoming plants tell the larger story of what an inspector focuses their attention on. Cuttings, bareroot, and tissue culture plants come from different sources, both domestic and foreign.

Regularly asked questions are: do these plants come from regulated locations; and if so, have they been shipped following the appropriate import regulations? Other frequent questions include: did the plants come from certified seed sources, virus-indexed mother plants; and does the facility provide training on sanitation methods if propagated on site?

Inspectors then moved the discussion to growing media, pots, trays and containers. All represent high risk and potential for the introduction into, or spread within a nursery, of soil borne diseases. Sterile soilless media is preferred by most reputable growers and propagators. Storing containers in a clean, sanitary location away from production areas ensures the best chance for clean healthy plants.

Site selection and maintenance help reduce the risk of contamination by pests and pathogens. Roads and pathways should allow for water to drain. Minimizing standing water both in the field and in the greenhouse can prevent pathogens via splash dispersal. Cull pile placement and frequency of attention to this critical control point is very effective at keeping away unwanted pests.

Adjacent fields are also a source of pests and diseases. Harvesting operations in adjacent fields can push pests over to nursery plants.

Anticipating these factors and controlling weeds in the perimeter will go a long way to reduce risks associated with growing nursery stock.

In addition to site evaluation, water management should be considered when it comes to control and avoidance of pathogens. Disinfecting recycled and recaptured water avoids contamination of plants and media by pathogens such as phytophthora and pythium. Limiting overhead watering, correcting drainage problems, raising containers off the ground and treating water are all excellent ways to prevent harmful waterborne pathogens, fungus gnats, mollusks and nematodes from entering and spreading into the plant production process.

Shipping and receiving plant material is another catch point for limiting the spread of pests and pathogens. Inspecting incoming plant

deliveries limits unwanted pests introductions. Segregating high risk plants and putting them through an observation period is a good practice. Segregating the same plant material from different suppliers will minimize the spread of unwanted pests from a single source.

Disposal of unsold plant material not actively being managed will also reduce pest risks. If plants need to be destroyed, make sure the load is secured so no plant material or pests will escape before reaching the dump site.

When it comes down to it, production practices and scouting for pest and diseases is the cornerstone of plant pest and disease mitigation for all plant producers. Controlling weeds and avoiding the use of media or soil known to be infested with pests or pathogens is an easy and effective practice. Scouting nursery fields and the frequency of this activity can save businesses big money by reducing the number of chemical treatments. Inspecting all plant deliveries and cleaning soil and plant debris from receiving docks is another good management practice.

Maintaining good records throughout the production process allows persons involved access to valuable information. Inventory numbers, dates, stock sources, scouting dates and pest or pathogen results are some of the more important types of records that should be documented. By having records readily available, work staff and regulatory officials can better track the many individual parts of nursery operations. SANC was designed to do just that: better manage all the critical control points related to nursery stock.

As inspectors concluded their visit at the facility, the discussion changed to compliance inspections or audits. At this point, the facility and inspector jointly develop best management practices to mitigate risks associated with the critical control points discussed earlier. After the management plan is approved, the facility is eligible to receive a certificate of compliance. State agencies are able to issue certificates of compliance that are recognized nationally or serve as the basis for international phytosanitary certificates.

Some may ask, what are some of the real world problems for this type of evaluation and training for compliance agreements? Good examples are: shipping Christmas trees out of gypsy moth infested areas or boxwoods from boxwood blight regulated areas. With the right amount of training and oversight, businesses will be more prepared for the ever changing menu of regulated plant pests and diseases.

➾ RE S E ARCH FOR THE R EAL WO R L D

Salt Tolerance — Another Factor to Consider When Selecting Roses Roses (Rosa spp.) have been a garden favorite for generations and their popularity continues today.

Dr. James Calkins

MNLA Foundation Research Information Director

within the genus Rosa, the namesake genus of the rose family (Rosaceae), there are about 150 species and thousands of named cultivars. Breeding and selection efforts have focused on a variety of plant characteristics including flowering (e.g., color, petal characteristics, repeat bloom), soil adaptability (e.g., drought tolerance, pH tolerance), growth habit, thornlessness, fragrance, cold hardiness, pest resistance, attractive fruits (hips), and fall color. More recently, being cold hardy and low maintenance have become increasingly important selection criteria as the landscaping public is increasingly interested in roses that are both beautiful and carefree.

Just as they are worldwide, roses are popular landscape plants in the upper Midwest, including Minnesota where many species and cultivars are grown. Although most of the varieties grown in Minnesota are of hybrid origin, four species of roses are native to Minnesota — Rosa acicularis (prickly wild rose), Rosa arkamsana (prairie wild rose), Rosa blanda (smooth wild rose, meadow rose), and Rosa woodsii (wild rose, Woods’ rose). Being found in all but a few scattered counties, Rosa blanda is the most widely distributed species in the state. Additional species are native just to the east and south in Wisconsin and Iowa, but may also be occasionally found in eastern Minnesota — Rosa carolina (pasture rose, Carolina rose) and Rosa palustris (swamp rose). All six species are rhizomatous, produce fragrant, pink or rosy-pink, single flowers and red, berrylike fruits (hips), and are valuable wildlife plants. In general, roses prefer full sun, a well-drained moisture-retentive soil, and an acidic to neutral soil pH (6.0–7.0). Although their flower color is limited, the wild species are certainly cold hardy and tend to be less susceptible to insect pests and diseases than many of the commonly-grown hybrids.

The Earth-Kind® Landscaping Program (http://aggiehorticulture.tamu.edu/earthkind/) is a Texas A&M

University program that was started in the early 1990s, and “uses research-proven techniques to provide maximum garden and landscape enjoyment while preserving and protecting the environment” by combining “the best of organic and traditional gardening and landscaping principles to create a horticultural system based on real world effectiveness and environmental responsibility.”

The Earth-Kind® initiative encourages water conservation, reduced fertilizer and pesticide use, energy conservation, and a reduction in the amount of yard waste entering landfills.

Specific to roses, Earth-Kind® is a special designation given to select rose cultivars by the Texas AgriLife Extension Service (part of the Texas A&M system) through the Earth-Kind® Landscaping Program (http:// aggie-horticulture.tamu.edu/earthkindroses/) in an attempt to identify the most adaptable roses available.

The Earth-Kind® designation is only awarded to rose selections that demonstrate superior pest tolerance combined with outstanding landscape performance with minimal inputs. Earth-Kind® roses must also be produced on their own roots. Recognizing a need for a broader perspective, the Earth-Kind® program has been expanded nationwide and includes the Northern EarthKind® Rose Trial program which was initiated in 2007 with a focus on cold hardiness and includes work by Dr. David Zlesak (University of Wisconsin, River Falls). The goal of the program is to identify roses that will grow across the country using environmentally-responsible cultural practices. Several Earth-Kind® roses are good choices for Minnesota landscapes including Carefree Beauty™ (‘BUCbi’) which was named the 2006 “EarthKind® Rose of the Year” by the Texas AgriLife Extension Service and is a proven performer in Minnesota.

The Earth-Kind® evaluation process does not include salt tolerance, but salt stress is both an existing and october 15

emerging factor from a landscape perspective. In general, roses are considered to be salt-sensitive and elevated soil salinity levels can have a negative effect on plant growth and performance. As a result, soil salinity can be of increased concern where water quality is poor, when reclaimed water is used for irrigation as a conservation practice, in arid regions where rainfall is limited and evapotranspiration levels are high, and in northern areas where deicing salts are commonly used for vehicular and pedestrian safety. In such cases, information about the relative salt tolerance of roses would be useful in selecting roses for landscape use, but is generally unavailable. In response to this lack of information on the salt tolerance of roses, a greenhouse study was conducted to evaluate the salt tolerance of 18 container-grown, Earth-Kind® rose cultivars including Belinda’s Dream, Cecile Brunner, Climbing Pinkie, Ducher, Duchesse de Brabant, Else Poulsen, Georgetown Tea, La Marne, Madame Antoine Mari, Marie Daly, Monsieur Tillier, Mrs. Dudley Cross, Mutabilis, Perle d’Or, Reve d’Or, Sea Foam, Souvenir de St. Anne’s, and Spice using two salinity levels based on the electrical conductivity of the irrigation water — a 1.2 dS·m-1 (deciSiemens per meter) nutrient solution and a 10.0 dS·m-1 saline solution prepared by adding sodium chloride (NaCl) and calcium chloride (CaCl2) to the control nutrient solution. The authors of the study report that roses tend to exhibit negative effects when salinity levels exceed 3.0 dS·m-1. A growing medium composed of equal parts of sand, composted bark, and ground bark (1:1:1 by volume) was used.

Plant growth and performance were quantified based on visual damage ratings, leaf greenness (chlorophyll content), shoot dry weight, shoot growth, flower number, flower dry weight, leaf gas 44

Of the 18 rose cultivars studied, Belinda’s Dream, Climbing Pinkie, Mrs. Dudley Cross, Reve d’Or, and Sea Foam were the most salt-tolerant and Cecile Brunner, Else Poulsen, Madame Antoine Mari, Perle d’Or, Spice, and Souvenir de St. Anne’s were the least salt-tolerant. Based on the results, the remaining seven cultivars were classified as moderately salt tolerant.

This information shows there are measureable differences among rose cultivars based on salt tolerance and, combined with evaluations of the salt tolerance of additional rose cultivars, and landscape plants in general, could be useful in breeding and selection programs to develop superior landscape plants. Most importantly, it highlights the need for additional information relative to sitespecific factors that can influence plant performance under landscape conditions including salt tolerance. Such information would be helpful in selecting plants for specific landscape situations that require fewer inputs resulting in healthier plants and landscapes that are more sustainable.

PATHOGEN IMMUNITY & OTHER BEE RESEARCH

Research focused on bees and other pollinators continues to search for answers regarding their health and survival. Specifically, nursery and landscape professionals may be interested in a number of studies that have recently been published in the open access, peer-reviewed journals PLOS ONE and PLOS Pathogens.

Transfer of Immunity

In a study published just two weeks ago — Transfer of Immunity from Mother to Offspring Is Mediated via Egg-Yolk Protein Vitellogenin — researchers affiliated with universities in Finland, the United States, and Norway believe they have solved an entomological mystery related to how insects — including bees — fight pathogens.

Although insects do not produce antibodies, they do have immune systems that are capable of recognizing specific pathogens and can transfer immunity to certain pathogens to their offspring. As reported by the authors of the study, this ability, referred to as transgenerational immune priming (TGIP), has been documented for a variety of insects including mealworms, red flour beetles, cabbage loopers, tobacco hornworms, and honey bees whereby exposure to bacterial constituents through ingestion and other means can subsequently impart immunity to their offspring. How this transfer is accomplished by insects in the absence of antibodies has, however, been a scientific mystery.

Working with bacteria, including the gram-positive bacterium that causes American foulbrood disease in bees by attacking and killing honey bee larvae (Paenibacillus larvae) and Escherichia coli, a gram-negative bacterium, the authors determined that an egg-yolk protein called vitellogenin can bind to bacterial constituents, serves as the carrier of immune priming signals, and may be responsible for the transfer of immunity to the next generation. For honey bees, the theory is that queen bees are exposed to pathogens through a variety of mechanisms including the presence of pathogens in their food. For example, pathogens may be acquired by worker bees while foraging for nectar and pollen and subsequently fed to the queen.

Upon ingestion, the fragments of these pathogens are transported in the hemolymph (insect “blood”) to an organ called a fat body which is also the site where vitellogenin is synthesized. Upon binding with vitellogenin, the pathogen constituents are transported to the ovaries and ultimately the eggs where they function as immunity triggers for the next generation. This is a very interesting theory that may help to explain how insects fight pathogens and may have the potential to enable the development of vaccines for beneficial insects like honey bees. Understanding the mechanisms involved in transgenerational immune priming may also be helpful in developing new methodologies for controlling insect pests.

Pathogens Predict Colony Strength

A second study — Pathogens as Predictors of Honey Bee Colony Strength in England and Wales — investigated the presence of pathogens in

honey bee colonies as a measure of colony strength (health) and evaluated the presence of various pathogens as potential predictors of colony decline in England and Wales. The research was conducted with the assistance of the National Bee Unit (NBU) whose apiary inspectors identified honey bee colonies that were in trouble for unknown reasons. The inspection process eliminated colonies that had died for obvious reasons including factors like starvation, queen failure, poor Varroa mite (Varroa destructor) control, or acute pesticide toxicity. Although the inspectors could not find a clear explanation for the vast majority of colony losses, when a primary cause was identifiable it was most often determined to be the result of a Varroa mite infestation. Based on subsequent pathogen analyses, the colonies where a definitive cause of decline could not be identified were categorized as being strong or weak and it was determined that weak colonies tended to be associated with higher numbers of pathogens in adult bees compared to strong colonies. Among the pathogens detected, only deformed wing virus (DWV) was identified as a good predictor of colony strength. These findings were consistent with the findings of other research efforts in search of predictors of honey bee colony decline. The findings also highlight the potential involvement of DWV in honey bee colony collapse. Given that Varroa mites are known to be important vectors of bee viruses and the protocol that eliminated colonies where Varroa mites were determined to be the cause of colony decline (poor Varroa mite control), the researchers suggest these results might indicate a “legacy effect” whereby DWV was able to persist in spite of effective mite treatments. Based on their findings, the authors suggest that beekeepers in England and Wales should concentrate on Varroa mite control, queen maintenance, and timely feeding as methods to reduce honey bee colony losses. A clear link was demonstrated between poor colony strength and presence of DWV. While controlling DWV would also likely be beneficial, effective anti-viral treatments do not currently exist. This research reinforces the belief that pathogens are a significant contributing factor in honey bee colony decline and adds to our knowledge and understanding of the role of biotic and abiotic factors in honey bee and honey bee colony health.

Aluminum in Bumblebee Pupae

Working with bumblebees (Bombus sp.), the objective of a third study — Bumblebee Pupae Contain High Levels of Aluminium — was to investigate whether aluminium (aluminum in the United States and Canada) might play a role in the reported declines in the populations of bees and other pollinators. The authors suggest october 15

Figure 1. A bumble bee (Bombus sp.) foraging for nectar and pollen (note the orange pollen in the pollen basket, technically called a corbicula, on the left hind leg) on purpletop vervain (Verbena bonariensis; also called purpletop verbena and tall verbena) — at a time when concerns about declining pollinator populations are commonplace, the green industry can play an important role in supporting pollinator health and survival by educating the public about the value of bees and other pollinators, supporting pollinator research, endorsing and practicing integrated pest management and the proper use of pesticides, and providing pollinator habitat by promoting and growing plants that benefit pollinators (Photo Credit: Jim Calkins).

an increasing presence of biologically-available aluminium in the environment as a result of human activities may have implications for bees. Although they were able to document high levels of aluminium in bumblebee pupae, which suggests high level of exposure, and observed an apparent negative relationship between aluminium level and the weight of pupae, they were unable to demonstrate any “other statistically significant relationships” between aluminium and bumblebee or bumblebee colony health. It was suggested that pollen, and perhaps nectar, were the sources of the aluminium relative to bees. The authors report that there are no comparable data for bumblebee adults or pupae, or the pupae of other terrestrial insects, but that aluminium levels between 4.6 and 15.5 μg/g on a dry weight basis have been reported for adult honeybees (Apis mellifera) based on a study published in 2012; levels that are much lower than the levels for bumblebee pupae found in their study. Although aluminium may have the potential to be toxic in high doses, any relationship between aluminum and bee health and performance would be purely speculative based on the information available at this time. Still, the idea that toxic effects of aluminium might be related to declines in the populations of pollinators is interesting and highlights the expanding search for cause-and-effect relationships that might threaten pollinators.

Predictive Model Developed

In a fourth study — Prospective Large-Scale Field Study Generates Predictive Model Identifying Major Contributors to Colony Losses — researchers monitored bee pathogens, bee population, and winter weather conditions for 179 honey bee colonies at three locations across the USA in an attempt to evaluate the potential contributions of these factors to honey bee colony losses. Eight bee viruses including Kashmir Bar Virus (KBV), Acute Bee Paralysis Virus (ABPV), Black Queen Cell Virus (BQCV), Chronic Bee Paralysis Virus (CBPV), Israeli Acute Paralysis Virus (IAPV), Deformed Wing Virus (DWV), Lake Sinai Virus (LSV), and Varroa Destructor Virus–1 (VDV-1) were followed along with the prevalence of Varroa mites (Varroa destructor) and the unicellular, fungal parasite Nosema ceranae. The results indicated that Varroa mites and bee viruses, mainly DWV replication, accounted for approximately 70% of colony losses. The researchers also developed a predictive model that indicates a single factor may not be sufficient to trigger colony losses; instead, a combination of stressors is more likely to impact hive health and be responsible for a colony collapse. The study did not account for other factors that might influence the health of honey bee colonies including things like migration, treatment with antibiotics and miticides, nutrition, or exposure to pesticides.

The researchers also developed a predictive model that indicates a single factor may not be sufficient to trigger colony losses; instead, a combination of stressors is more likely to impact hive health and be responsible for a colony collapse.

Pollen-Stressed Larvae Become Poor Foragers and Waggle Dancers

And finally, a fifth study — Honey Bee Workers That Are Pollen Stressed as Larvae Become Poor Foragers and Waggle Dancers as Adults — investigated the effects of poor nutrition (pollen stress as a result of limited pollen availability) on European honey bees (Apis mellifera L.). The findings indicated that pollen stress during larval development had significant negative effects on the health and performance of the adult worker bees (body weight, longevity, foraging activity, and waggle-dance behavior) that were produced when the juveniles became adults.

Nutritional stress during the larval stage resulted in adults that weighed less, were poor foragers, had shorter lifespans, and were less able to communicate the location of food sources through the waggle dance.

In addition, the researchers believe these effects may be compounded over time as nutritionally-stressed foragers that do not collect sufficient food to avoid nutritional stress in the developing larvae they care for may result in those larvae also becoming poor foragers with concomitant effects on the performance of the colony as a whole.

In short, they found that pollen stress during larval development had far-reaching negative effects on the foraging and recruitment abilities of adult bees. Since foraging for food and recruitment are ultimately “the most important tasks that honey bees perform as provisioners for their colonies and as pollinators” of cultivated crops, the researchers believe these findings “warrant concern.” It was also suggested that the effects of poor nutrition may be compounded by other stressors that have the potential to october 15

Helping to be Part of the Solution

Minnesota Nursery and Landscape Association (MNLA) members may also be interested in viewing a webinar entitled “The Bees’ Plight and Prospects: Helping to be Part of the Solution” by Dr. Marla Spivak (MacArthur Fellow and McKnight Distinguished Professor of Entomology at the University of Minnesota) that was presented earlier this year (June 9, 2015) and is available for free through the Minnesota Association of Soil and Water Conservation Districts (www.maswcd.org) and the University of Minnesota Water Resources Center (www.wrc.umn.edu) websites. The presentation is just over an hour long and summarizes the findings of recent honey bee research at the University of Minnesota and specifically the critical role proper nutrition plays in promoting honey bee health and preventing colony losses. The importance of providing pollinator habitat, including the availability of high quality floral resources that provide nectar and pollen, the respective sources of energy-rich carbohydrates and proteins and lipids (fats) required by bees, and maintaining a low immune system activation level in promoting bee health and survival is highlighted.

Concerns about declines in pollinator populations continue to be in the news and pollinator health continues to be an important focus of agricultural and entomological research. A variety of biotic and abiotic factors have been suggested as both real and potential threats to bees and other pollinators and have been reported as being responsible for honey bee colony losses. Varroa mites (Varroa destructor), viruses, and habitat losses remain the primary suspects, but a variety of other factors, acting alone or in combination, continue to be investigated including nutritional deficiencies, weather, beekeeping practices, genetic weaknesses, and pesticides and the ultimate cause is likely to be multifactorial. Green industry professionals continue to be engaged and have an important role to play in educating the public about pollinators, supporting pollinator research, creating quality pollinator habitat, and promoting and protecting pollinator health.

➾ S KIN CAN CER

A

few years ago, one of our longtime customers approached me with a small bandage on her face … talking about a skin cancer she had removed. She was very proactive, encouraging me to have our team’s awareness raised about how easy it is to get skin cancer since “we work outside all the time.” (Skin cancer is the most common cancer in the U.S., affecting 1 in 5 adults.*) She wanted to make the point that as an industry we need to be better about awareness.

She was right, she IS right. (And while I heard her at the time, I didn’t really LISTEN.) I waited a year longer than I should have. Finally, one of our crew guys teased me about “having my ear pierced” — a mole on my earlobe that had gotten large enough to be (really) noticeable. About that same time, I had the annual burn on the tops of my ears, one side developing a “crispy blister” with an early burn that became larger and more irritating than normal. Finally, between my crew guy’s teasing and my wife’s encouragement, I went to a dermatologist. It wasn’t the crispy burn side that was the problem … it was the mole.

Skin cancer (particularly Malignant Melanoma) is sometimes casually referred to as the “landscaper’s disease” — with good reason.

We spend a disproportionate amount of our work days in the sun, and likely don’t take enough precautions. Melanoma — once it has spread regionally — has only a 63% survival rate (but a 98% survival rate if caught and treated early.)

And so, during April 2013 (not a convenient season for a major surgery), I underwent surgery to remove a lymph node and most of my left earlobe (now reconstructed.) They were able to get clear margins on everything. My dermatologist, in our now-quarterly visits, continues to remind me just how lucky I got … melanomas of my size have almost always metastasized.

I got lucky. And now I’m trying to “pay it forward” so you might be lucky, too.

1 in 50 Americans will develop Melanoma (the most fatal of skin cancers), and by age 60, rates are twice as high in men vs. women.

(Not accounting for any industry-specific “skew” factor.) Simply

put, guys, we don’t get checked early enough or often enough. Just in the past two years, I have heard so many stories about others who have had similar experiences … but guys aren’t as good about talking about these things. We’re good at avoiding.

What I love about my job is that I get to work outside, wear shorts, enjoying plants and fresh air. I feel really fortunate that I’m not “stuck in a cube” somewhere — I’m active and healthy and enjoying nature almost every day. One of the (very) few downsides of that is that it puts me more at risk for skin cancer, a fact which I should have known and taken steps to prevent.

I’m writing this because I didn’t listen to the first three people who told me to have myself checked out. Our industry should do a better job warning people about the possible effects of sun exposure and we should incorporate preventative remedies into our company culture: sunscreen, wide-brimmed hats, long sleeves, and shady sites for breaks.

It’s our “slow season.” If you have ever wondered about a blotch on your skin, NOW is the right time to go see a dermatologist to get it checked out. If you’ve avoided having something looked at because you just don’t know who to call, you don’t have an excuse anymore — I see Dr. Larisa Speetzen at Park Nicollet in St. Louis Park**. Even two years later, I see her every three months. While that sometimes feels like an annoyance in my schedule, it’s far preferable to the alternative. * https://www.aad.org/media-resources/stats-and-facts/conditions/ skin-cancer ** 952.993.3260. If Park Nicollet isn’t your preferred healthcare provider or St. Louis Park isn’t convenient, find someone closer to you. But find someone.

A Worthwhile Partnership As a college instructor, I get many calls each year from local landscape companies asking if I have any students who would be potential employees.

Jay Siedschlaw

Landscape Design and Construction Instructor at Hennepin Technical College

the need for employees in the green industry is huge. Unfortunately, as the need for employees has increased, the enrollment of students in this industry has declined. I believe in education not only because I am an instructor, but also because I think the best employees are educated ones.

I have a potential solution to the employment problem.

Local green industry businesses need to take an interest in the community of young people. Business owners need a good selection of employees to choose from, who can do the work and grow within the company over time. Connecting with high schools and colleges is a great place to start. Partnering with a high school or college and providing opportunities to students will provide your business with educated and experienced employees, as well as providing students with opportunities to be successful in a landscape career.

Recently at Hennepin Technical College, we have partnered with two high schools in the Twin Cities area to encourage students to consider careers in landscape, horticulture, and urban forestry. We have opened our doors at the college for high school students to tour and experience what a career in the landscape industry might be like. A resource that has been overlooked in the past is that of the local FFA chapters. The FFA Chapters at local high schools have landscape design focused curriculums. Two curriculums that many high school students choose from are Animal Science and Horticulture. Animal Science has been a popular choice for the past few years, but a shift is starting to happen.

High school teachers are reporting that they feel that students are starting to inquire more recently about “green” careers. Greenhouse growing, landscape construction, and design tend to be areas of interest.

Each school is given a 15' × 18' space to use for the creation of a landscape.

Schools such as Forest Lake, Stillwater, Buffalo and Plainview-Elgin-Millville participated last year. The next time you are at the Fair, check out the gardens just outside the Miracle of Birth Center. Hennepin Technical College and Natural Creations Inc. partnered with the landscape program at Buffalo High School this past summer to create a garden. It was exciting to see the pride and the excitement the students had in creating a water feature and garden. The students were very concerned with the movement of water and the overall construction process. Many students were interested in the choice of plants and the color combinations that could best represent their “school colors.” This interest in landscape design and construction by these students gave me great hope for the future of our industry!

So how are we going to take this small glimmer of hope that I witnessed and multiply it? We need to connect. We need to connect students/business/educators.

Trying to recruit employees on your own is difficult, if not impossible. Recruiting skilled employees is even more difficult. Finding employees that stick around more than two years is rare. But if you are willing to step out of your comfort zone, there is a solution.

Here are some of the best ways you can partner with a school and connect with students: october 15

Employers that have found a great employee that needs an education have found it worthwhile to help pay for their tuition. Many times this includes an agreement of employment for a certain amount of time to ensure that the investment pays off for the employer.

The main goal is to get involved with the students. It might not happen in the first visit. It may take several visits, but the key is to support high school and college programs. The companies that take a sincere interest in the education of students are the ones that make connections. Just showing up to tell the students how many jobs you have available is boring. Students need to see what you do. They need to hear why you do it. They can sense if you’re sincere or not immediately. Many times after a business owner leaves my classroom, students discuss the company. They make quick decisions.

The companies that have invested their time into meeting me and my students have found it worthwhile.

A recent article that I read that speaks to this connection is from EdWeek.org. It shares lessons on how to create better partnerships with businesses. The web address is: http://blogs.edweek.org/edweek/ global_learning/2013/01/how_schools_can_successfully_partner_with_ local_businesses.html Some of the highlights that I gained from the article are: 1. The fact that many students drop out due to a lack of relevance is key issue. This is a driving force for me when

designing curriculum. Business partners are the resource that I go to for what is relevant.

2. Having employers stress the need for soft skills is always important.

Employees need to be able to communicate with each other and clients. Things like teamwork, communication and presentation skills are a must.

3. The article also stresses some of the benefits that employers might gain by hiring a 16 or 17 yearold student. Students are learning relevant 21st century skills and global knowledge. They have a lot of energy and excitement, plus a desire to succeed. Who wouldn’t want someone like that working for them?

And these students return from college as highly skilled laborers.

With two thirds of America’s economy driven by consumer spending, a well-educated worker is preferred to a drop-out. The Alliance for Excellent Education’s Bob Wise points out, “Ask any retailer whether their future depends on consumers earning a high school dropout’s $9 per hour or the $20 per hour of postsecondary achievement.”

In conclusion, this is something that takes a lot of hard work.

It’s not easy. Everyone wants easy; this is not easy. It takes time. It takes stepping out and making connections.

In conclusion, this is something that takes a lot of hard work. It’s not easy. Everyone wants easy; this is not easy. It takes time. It takes stepping out and making connections.

You’ll have to stand in front of teenagers.

Scary. They will be checking their phones, texting each other about everything you’re saying. Really scary. But when a student comes up to you after you have shared why you love doing what you do, it will be worth it. Period. You may have just ignited a spark that carries that student into a career; possibly a career with your company.

A career they will love.
