Enhancing Business Acumen and Career Training Opportunities This month, I’d like to focus in on one of the six core areas of the latest Minnesota Nursery & Landscape Strategic Plan: Education.

Cassie Larson MNLA Executive Director


MNLA .biz

But, that term is widely used. What does that mean specific to MNLA? It means, MNLA will offer educational opportunities for members to enhance their business acumen and career training opportunities. There are several ways MNLA will work to accomplish this goal in the coming months and years ahead. First, developing and offering specialized educational programs on topics including human resource management, succession planning, and other critical business issues. Coming up on February 27, MNLA will offer a half day “Hot Legal Topics” seminar to help business owners assess where there may be updates or new regulation they may need to address. The CEO Track at Northern Green also plays a critical role in helping address business ownership issues. If you’ve never attended, check it out at Northern Green 2019. Second, exploring opportunities to collaborate with other organizations to offer education, training, and resources focusing on critical issues impacting small businesses. Many good resources exist already, so let’s take advantage of them instead of re-creating the wheel. MNLA has been in recent discussion with both the Minnesota Landscape Arboretum and Minnesota State Horticultural Society about how we can work together on educational programming that is pertinent to all horticultural and landscape audiences. We also partner with organizations like Landscape Management Network and others to present top notch programming for members. Third, re-evaluate the certification program to focus on developing individual skills to improve member

february 18

businesses, not just individual knowledge of horticultural topics. Certification could be re-focused to better reflect the necessary skills to move along career pathways and build business-related skills. The certification program has undergone a facelift in recent years and is now available in an online format, which has enabled MNLA to offer the test multiple times throughout the year rather than just one date. Many companies are using this as a platform to assess knowledge and promote employees. A task team has also been commissioned and is close to securing a consultant to work with MNLA on creating and promoting career paths within the green industry. Part of this initiative will be to identify skills and educational knowledge needed to move from one level to the next. This is a topic that will be expounded upon in detail in 2018. Is this something you’re passionate about? Get in touch and we’ll get you involved! As you know, having the knowledge and tools to both run a business or get the job done is crucial. MNLA has several events coming up that will help you build your business acumen and/or obtain skills training to take you to the next level including: Turf Maintenance, Pesticide Certification Workshop and Exam, and PLT Relicense. Plus, new this year, there will be a Foremanship Training class in March. See the events listing on page 8 of this issue for further details. We look forward to seeing you at these and other upcoming events.

TELL US YOUR STORY ON SALES TAX If you’re not receiving our weekly Grassroots, update, you may not know that MNLA has created an advisory committee to discuss possible changes or reinterpretations of the state’s sales tax related to green industry business operations. As you likely know, the current sales tax code at the state level is confusing and contradictory in many cases so we would like your personal and business input on where the pressure points are and what changes you would like to see happen if we were to make this a top priority. If you have been recently audited or have seen uneven or unexplained applications of the current sales tax on our industry, we need to hear from you. If you are interested in providing information or recommendations for this association effort, we welcome you. Please contact Larry Johnson at the MNLA office (larry@mnla.biz, 651-633-4987) for more information and to sign up to receive free weekly grassroots updates via email.

COMING TO THEIR SENSES It appears to me that certain attributes of mind, as it occurs in Man are common to Plants. — Dr. William Lauder Lindsay, physician and a botanist 1876

Top left: Responding to gravity, the aerial roots of a banyan tree know up from down. Top right: Trees warn each other of imminent leaf-eating-insect attack. Left: Mimosa is native to South and Central America but is now grown world-wide as an ornamental because of its fascinating moving leaves. Left page: A sunflower can sense a change in their environments (gravity, light or smell) and bend in response.

arden flowers have a sense of smell? I don’t think so. The vegetables growing in my backyard have an aversion to being touched? Surely not. Trees remember the weather? You’re kidding. So how does a cherry tree “know” when to flower? Or is it programmed by evolution to switch on flowers in spring? Do not underestimate plants. On a genetic level plants are more complex than many of the animals that share our planet. Plants have the ability to sense what is going on in the outside world and to share that information among flower, stem, leaf and root. The flower may sense the sun’s direction, but it’s the stem that must twist in response. Plants can feel. A burr cucumber vine can detect and respond to a weight of .25 grams. If humans, who can barely detect two grams, possessed the same level of sensitivity a lover’s kiss would resemble a slap in the face. The Venus flytrap feels its prey; one touch and snap! The cause is a chemical reaction that is triggered by two hairs on the inside surface when touched. The hairs can differentiate between the touch of a raindrop and that of an edible fly. There is also the Mimosa plant whose frilly leaves momentarily wilt when touched. The Mimosa uses the same chemicals for neural communication as humans. Plants can smell. A hard avocado placed in a brown bag with a ripe banana will ripen because the avocado “smells” the ripe fruit’s

chemicals. This has the ecological advantage of ensuring all the fruits on the tree ripen together. A full display of ripe fruits guarantees a ‘ready–to–eat” market for foraging animals, which then disperse the seeds as they go about their daily business. Plants also sense gravity. Scatter corn kernels over the soil and shoots grow up and roots down. Aerial roots of a banyan tree always grow down, even though they start several feet up in the air. Trees can detect not only insect damage to their neighbors but even the presence of torn leaves. They respond by releasing self-protective chemicals to make their own leaves less palatable. We pay too little attention to the sophisticated sensory machinery in flowers and trees. On a broad scale, we share biology not only with chimps and dogs but also with begonias and sequoias. So next time you are out in the garden ask yourself: Can that tree see me? Will that vine know where the nearest support is? Does the flower feel the bumble bee? Maybe it’s time, as Joni Mitchell sang at Woodstock, “to get ourselves back to the garden” and take a closer look at the plants. FAITH APPLEQUIST

MNLA Legislative Agenda Finalized Over the past several months, the MNLA Government Affairs Committee held monthly meetings to discuss issues pending in and around the State Capitol and took member concerns on legislative issues to help inform the creation of our 2018 Legislative Agenda. To help members who plow snow over the winter and apply salt to help melt ice in parking lots, the committee voted this fall to take a lead role in passing liability protections for these members, helping build a coalition Larry Johnson of environmental groups and business associations to Government Affairs Director come together to prevent oversalting, often done to avoid possible litigation. This group has worked to bring lawmakers from all sides together to pass this commonsense reform in 2018. The association is also leading efforts to change laws related to irrigation contractors’ right to test and rebuild back flow prevention assemblies. Recent changes to the Minnesota Plumbing Code made it impossible for our industry’s certified backflow testers to also have the right to train and certify to rebuild backflow prevention assemblies, which is now limited to qualified licensed plumbers. As we did last year, we’re also working as part of coalition groups to pass uniform state labor standards to make a consistent market across the state for services as well as supporting efforts to end the state “duty to defend” laws for subcontractors. For a full list of all the issues the staff at MNLA is monitoring and taking an active part in currently, please see the inset box on this article. You can also find more information on public policy issues and view our full legislative agenda by going to the MNLA website. We hope you will also register and attend our Annual MNLA Day on the Hill coming soon on March 7th. This event will give you a full briefing on issues pending at the Capitol as well as a chance for you to answer questions on policies of interest to you and your business personally.

When it comes to leadership, everyone and every business has their own definition of that term. They also have their own requirements and expectations. As a leadership coach and business advisor, I hear various requirements, expectations and demands placed on individuals every day. I also hear concerns from owners and CEO’s about the need for more leaders, better leaders.

ost agree there is a leadership gap today. According to Workplace Trends, in the next year alone more than 3.6 million baby boomers are set to retire and more than one-fourth of millennial workers (born: early 1980’s to around 1996) are poised to become managers. Oh, and by the way, 91% of millennials aspire to leadership positions. Now include generation X (born: mid-1960’s to early 1980’s), many of whom have been patiently waiting in the wings for their chance to move into stronger leadership roles and we definitely have a lot of interest. So why are we feeling like there is a leadership gap if we have all this interest? It is the speed at which this gap must be filled. That’s an unknown and the challenge we face. We are feeling a gap today because it’s hard to wrap our arms around just exactly what leadership means to an organization at any given time. Next generation leadership development has moved to the top of the priority list for many of our clients. Leadership becomes a strategic initiative based on philosophy around culture, leading people, and building out bench strength (succession). It cannot be completed in a single activity or event. Nothing happens in an organization without leadership. Leadership acts as the catalyst that makes all other business strategies and resources work together. A 2016 Forbes article identified five Leadership Challenges. See if any of these resonate with you and your organization: 1. Creating a shared purpose: “The challenge for leaders, then, is in translating what they know and how they’ve been raised in an organization into a language that Millennials speak and that resonates with them.” I would submit to you that your organization may need to include the Gen X work group as well. Gen X may have reached management levels, but have they developed into strong leaders? Do you have any Gen Xers or Millennials in line for succession? Translating into a language that resonates with both generations is a multi-pronged strategy.

2. Measuring ROI [return on investment] of soft skill development: “…the ROI Institute notes that “soft skills” create agile organizations, develop innovative companies, make the best places to work, and build the most admired companies. Soft skills bring out the best in people as their behaviors and competencies are shaped to fit the strategy of the organization, the desired work climate, and the ever-changing, unpredictable landscape.” This is why MNLA’s Green Industry Leadership programs are is focused on leadership soft skills. We zero in on selfawareness of skills that employees haven’t had the opportunity to learn much about in school, technical training, and even on the job experiences. Many executive managers steer away from the soft skills because they view them as just that…too soft, hard to quantify feelings sort of stuff. And yet research has beyond a doubt proven that it’s the soft skills that make or break a successful leader (Google “soft skills stats and ROI”). Soft skills are difficult to learn and even more difficult to turn into consistent, meaningful leaderlike actions. Your return on investment may take months to prove because you are dealing with a people development strategy, not a tactical one-time fix. To get a pulse on this type of development consider surveys, feedback sessions, identification of additional projects or responsibilities, the results of change initiatives, pre and post tests after a course, or measurements of improved/effective communication methods. Take for example, Chris Wacker from Bailey’s. He graduated from the Green Industry Leadership Institute (GILI) in December 2015. He is now not only the propagation foreman at Nord Farm but has added seedling propagation to his responsibilities. This includes supervising anywhere from 8-40 employees based on the season. “There’s never a dull moment…it keeps me on my toes watching out for all my crews.” When asked about soft skills he learned from class that helped him the most in his job he answered, “The ability to adapt and plan ahead.” Simple to say, hard to implement when leading multiple crews through multiple growing programs. Chris has designed communication methods, like white boards to stay on top of the ever changing cycles. “The class has helped me realize how much responsibility I can take on because I know how much detail I can handle based on my organizational skills.” Keep in mind that before you can prove ROI, you must first clearly understand what it is that you want improved. What does successful leadership behavior look like? 3. Identifying and communicating what success looks like: Are you clear on what it is you are looking for in a leader? Are you clear on your long term strategies and how leadership fits in with those strategies? What are the results that you are looking for? If you identify those results, then work backward from there to identify the attributes and strengths

you need in leaders to get you to that end game. Chris Wacker would look for an individual who is motivated and can adapt to change. He now has a pretty good picture as to what that looks like in his work world. Production-wise, this translates into managing 12.5 million plants in one year…successfully. Can your leaders communicate the strategies to get your company to your end game? As the article explains, “…keep in mind that while the leader’s vision of success won’t change, the means by which the company arrives there surely will, which means leaders also need to communicate the value of adapting to change.” 4. Building trust: “A lack of trust in business (55%) has etched itself into one of the top four concerns based on a study by PwC. Can trust be built without personal (i.e. face-to-face) interaction? Certainly. But at a much slower rate…” So what does this have to do with your business? Do you know if you have a trust issue within your organization? You may have a trust issue if your organization fails to get projects completely done because your people didn’t get on board. You may have a trust issue if you’ve noticed lately that your best manager has become defensive and won’t look you in the eye at meetings. You may have a trust issue if you proclaim that your leadership team never disagrees (but have never asked why). Do you know how to uncover the trust level of your team? Consider reading Patrick Lencioni’s book, “The Five Dysfunctions of a Team”. We use this at Resultants For Business with all of our clients, who happen to be leadership/management teams. If you look at Lencioni’s pyramid, trust is at the base. It is the foundational piece and the basis for everything else that is built within an organization. If there is little trust, any attempts to lead or develop leaders has a much higher rate of failing. Can an organization meet their goals without trust? Sometimes. However; it takes its toll on your people. Put simply, with low trust in an organization, it becomes a constant, uphill battle creating huge tension within the work environment. 5. Perspective management: “Perception is everything, especially when our perceptions drive our attitudes and our attitudes impact others. How leaders show up is contagious. The difference between leaders who show up at work and those who show up to work is intentionality. The former reacts to fires whereas the latter proacts to the ingredients that cause fires by using selfmanagement tools.” One of our industry guest presenters was Dennis Ullom of St. Croix Tree Service (purchased by Sav-A-Tree). He explained to our GILI class, “My perspective on ownership completely shifted when I recognized that I wasn’t in the Tree Business or the Green Industry; I was in the people business!” At the Green Industry Leadership Institute, the curriculum focuses on self-awareness. This includes: understanding who I am and how I react in front of others, how my personality style affects others, my intrinsic motivations, my auto-response february 18

to conflict and change. This awareness influences how we plan and prioritize, how we communicate out to others (appropriately or inappropriately), how we manage time, how we view the bottom line and the ROI we bring, and how we influence (or not) our customers. This boils down to behavior. Behavior won’t change until there is self-awareness which can trigger a feeling (yup there’s that word again) for a need to change. At the Institute, we provide a safe environment for students to learn not only the latest leadership concepts, but to experiment and try on new perceptions, openly dialogue with others and self-analyze where they are at today and where they want to go in the future. Management does not necessarily mean leadership. This is what the students uncover about themselves through the 10 month course. Do you have a leadership gap? You may not have one today, but look out 3–5 years…will you have a leadership gap? How many baby boomer leaders are leaving your organization in the next five years? How many Gen X and Millennials are ready to take on those leadership roles? How will they gain experience before the box on your org chart empties? This is a long term strategic move. Remember, it is the speed at which you can fill those gaps that is the challenge. What’s your plan? TERRI WILCOX

DON’T BE AFRAID! As you know—or we really hope you do by now—the Minnesota Nursery and Landscape Association is constantly working with elected officials and regulatory specialists on your behalf.

Larry Johnson | Government Affairs Director

Staff and members meet with regulators, legislators and staff each week on a number of issues that affect you, your business and your customers daily. If you will allow us a moment of pride, we are pretty good at what we do. But with your help, we can be even better! As we hope you know, the Association hosts an annual event called our Day on the Hill every March. This one-day event gives you, as members, a crash course on legislative issues facing the green industry and brings you face-to-face with state legislators for a discussion on specific issues pending during the legislative session. (Please see the Scoop article on page 16 highlighting our legislative agenda for 2018 for more information on specific issues we’re working on this year.) I have worked at and with the Minnesota Legislature since I was in college, so I really don’t count as “normal” but I do understand that it’s normal to be intimidated by the thought of interacting with legislators who are often in the news and on television and carry a level of influence and power. Some of you as volunteers can attest that legislators (as I often tell my Boy Scouts about animals in the woods) are sometimes as nervous about meeting with you as you are of them. They become experts on very narrow specific issues pending at the legislature and are not omniscient and often research issues to be better informed before meeting you. These “Days on the Hill” events are our opportunity as experts 24

to help educate them on how their votes and the laws they pass would impact the industry. We will spend part of the morning educating you on specific issues and practicing for your meetings with your State Representative and State Senator. We will also be traveling in groups whenever possible, so you don’t have to remember every last detail and can divide up the duties. Being personally involved in our grassroots advocacy will help you know that at the end of the day, you did everything possible to help the industry and your business thrive. As we’ve said before, it may be unnerving, but the rewards for both you and the industry cannot be matched. Our continued success as an industry depends on the hard work of volunteers like you. Still don’t feel that this one-day event is within your comfort zone? Or do you have other commitments on March 7th? I encourage you to send an email or make a call to your legislators to tell them about the industry and your company and to invite them to meet with you at your business—home field advantage sometimes helps! If you have any questions or further concerns about visiting the Capitol that day, please don’t hesitate to call or email me any time.

s previously reported in Research for the Real World updates in February, 2012, and June, 2017, boxwood blight is a new and very serious threat to boxwood (Buxus spp.) plants in nurseries and designed landscapes. Boxwoods are highvalue plants and are one of the most popular shrubs planted in European and North American landscapes. The disease is caused by two closely related, but different species of fungi — Calonectria pseudonaviculata (synonyms — Cylindrocladium pseudonaviculatum, Cylindrocladium buxicola) and Calonectria henricotiae. It was initially believed that Calonectria pseudonaviculata was the only pathogen involved, but Calonectria henricotiae was subsequently isolated from plants growing in Europe and named as a separate species. There is no known cure and while fungicides can help prevent initial infections and reduce the spread of the disease, they are not a solution. The hosts and symptoms of both species are essentially the same, but C. henricotiae appears to tolerate warmer temperatures. From a disease and prevention standpoint, it is important to note that C. henricitiae has not yet been found in North America and is not believed to be present in North America at this time. As spring and a new production and landscaping season approaches, now is a good time to learn more about this devastating disease and its prevention. Boxwood blight (also called box blight and boxwood leaf drop) is a devastating disease that was officially confirmed in the United States just over six years ago and has been spreading rapidly ever since. First confirmed in Connecticut and North Carolina in October, 2011, the boxwood blight fungus attacks leaves and stems causing defoliation, severe dieback, and death of infected plants and can easily overwhelm and destroy susceptible boxwood plants in a single growing season. Although some variation exists among species and cultivars, all species of boxwood (Buxus spp.) appear to be susceptible including those grown in Minnesota. Most recently (2016) boxwood blight was confirmed in California, Illinois, New Hampshire,

South Carolina, Washington, and West Virginia; of these, the finds in two counties in northeastern Illinois in December, 2016, are the most recent and the closest to Minnesota. The disease has subsequently spread quickly and has thus far been confirmed in nursery, garden center, and landscape settings in 24 states — Alabama, California, Connecticut, Delaware, Florida, Georgia, Illinois, Kentucky, Maryland, Massachusetts, Missouri, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Virginia, Washington, and West Virginia. Not surprisingly, given the presence of boxwood blight in Maryland and Virginia, the disease has also been documented in the District of Columbia and has also been confirmed in three Canadian provinces — British Columbia, Ontario, and Quebec. Boxwood is an important nursery crop and a popular landscape plant and various species and cultivars have been planted in landscapes and gardens for millennia including by the Egyptians, Greeks, and Romans. In Europe, and to a lesser extent in eastern North America, boxwoods are often the foundation of estate plantings, most notably in formal gardens, and can be found in some of the most famous gardens of the world. An increasing number of boxwood cultivars are sold today and some are hybrids between common boxwood (Buxus sempervirens; also called American or English boxwood; not reliably cold hardy in Minnesota, but can sometimes be grown in protected locations) and Korean littleleaf boxwood (Buxus sinca var. insularis; formerly Buxus microphylla var. koreana; cold hardy to USDA Cold Hardiness Zone 4 in Minnesota). In addition to the Korean littleleaf boxwood parent, several of these hybrid cultivars are also cold hardy in Minnesota if planted in the right location. As a consequence of their popularity, boxwood is the top selling evergreen nationwide based on the most recent data available from the USDA Census of Horticultural Specialties (2014), and is also the most popular broadleaf evergreen based on february 18

sales value (over $126 million; wholesale and retail combined) and the number of plants grown. Although not as common in Minnesota’s colder landscapes, the popularity of boxwood is on the rise in the state. The historical and contemporary popularity of boxwood can be attributed to the many positive characteristics of the genus including shade tolerance, evergreen foliage, compact habit and symmetrical form, fragrant flowers, fine texture, landscape use versatility, soil adaptability, pest resistance (insects, diseases, rabbits, and deer), landscape longevity, and shearing tolerance and popularity as a formal hedge plant. Requiring well drained soils, boxwood will grow just about anywhere so long as the soils are not poorly drained and excessively wet and the cold hardy selections of boxwood are one of only a few broadleaf evergreens that can be reliably grown in the warmer parts of Minnesota so long as they receive winter shade. Although it is not believed that the disease originated there, boxwood blight was first detected in the United Kingdom in 1994 and subsequently spread quickly, becoming widely distributed across the country within six years (2000). Since then the disease has spread to other European countries (1998–present), New Zealand (1998), and North America (2011). Boxwood blight has also been found in the wild in native boxwood populations in Europe and the Republic of Georgia in western Asia and native populations in Europe have been significantly impacted. Although much has been learned about the life cycle of the boxwood blight fungus since being recognized as a serious threat to the nursery and landscape industry and native boxwood populations, the origin of the disease remains a mystery. It is clear, however, that human-mediated transport is the primary long-distance vector and the introduction of the disease to new areas is most likely associated with the importation and movement of infected plants or other infected materials. In areas where boxwood is a popular landscape plant and widely planted, boxwood blight is a serious and growing concern that poses a very serious threat to the boxwood industry and existing plants in designed landscapes in the United States and Canada. Fortunately, boxwood blight has not yet been documented in Minnesota and hopefully we can keep it that way. The symptoms of boxwood blight can sometimes be confused with the damage caused by other boxwood pests and abiotic disorders and can sometimes be difficult to identify. This is especially true for those who are not familiar with the disease, but resources that can be helpful in identifying boxwood blight are quickly becoming available. The primary symptoms of boxwood blight include circular, brown leaf spots with darker margins which may eventually coalesce to cover entire leaves and stem cankers that appear as blackish-brown streaks on affected stems resulting in significant defoliation and dieback within the crowns of infected plants resulting in a blighted appearance. Infected leaves typically turn light brown before defoliation occurs. Under favorable conditions (warm and moist), downy, white fungal growth and spore masses may be produced on the undersides of the leaves and along the stems and are visible to the naked eye. The elongated (sometimes diamondshaped), dark brown to black stem cankers on the green stems are perhaps the most distinctive symptom for the identification of boxwood blight. Considered a shoot blight, it has generally been accepted

that roots are not affected, but more recent research suggests this is not the case. Although new shoots may sometimes arise from the crown, plants are typically severely weakened and eventually killed. Although fungal growth can occur when temperatures are above 5º (41º F), warm (18-25º C (64.4-77º F) moist conditions are preferred with optimum growth occurring at 25º C (77º F). Growth has been observed to slow down at warmer temperatures and reportedly ceases at 30º (86º F). Extended exposure to 33º (91.4º F) appears to be lethal. Treating cuttings with hot water (47.5º C; 117.5º F) has been suggested as a therapy for killing the pathogen during commercial propagation. Asexual reproduction occurs in the form specialized branches of the fungal mycelium (conidiophores) that produce clusters of sticky conidia (asexual spores) which function in dispersal and reproduction when they germinate to produce new fungal colonies. The clusters of white conidia visible to the naked eye and are produced on the undersides of infected leaves and from the stem lesions. Sexual reproduction has not been observed. Boxwood blight infections can result from both spores and mycelia. Boxwood blight spores (conidia) are easily moved about by splashed water droplets from rain events and overhead irrigation which are the primary methods of localized dispersal in landscapes and production facilities. Wind may also move the spores short distances. Longer distance transport is easily accomplished when the sticky conidia adhere to just about any surface (e.g., contaminated clothing and footwear, pruning tools and other equipment, shipping containers) and these contaminated articles are moved to new locations by people. Runoff from irrigation and rainfall, and the movement of contaminated soil and plant debris are also a potential methods of long-distance dispersal. Given their stickiness, it may also be possible for the spores to be moved on animals and perhaps even insects. Of course, infested plants and plant parts (cuttings, Christmas/holiday greenery, etc.), and plant debris and contaminated soil, are also means of introducing the disease to new areas and can be primary vectors for long-distance spread. The boxwood blight pathogens are able to survive in infected plants and plant debris and can survive for five to six years or more in infected plant debris and contaminated soil. The disease does not require a wound for infection to occur, but high humidity or a film of water is required. When the conditions are suitable, the conidia can germinate within three hours and are able to penetrate the leaves through the stomata or directly through the plant cuticle and epidermis within five hours. Under ideal conditions the pathogen can complete its life cycle within one week and plants can become symptomatic and be defoliated very quickly. It is important to understand, however, that under less than ideal conditions, or when plants are treated with fungicides during production, the disease can remain dormant and infected plants may, as a result, be symptomless. Plants with partial resistance can also harbor the pathogens. As a result of these complicating factors, shipping or otherwise moving such asymptomatic plants can be a significant vector for spreading the disease to new areas and has been referred to as the “Trojan Horse” or “Typhoid Mary” syndrome. Interestingly, the 2017 holiday season was somewhat of a “poster boy” for the potential spread of boxwood blight on greenery february 18

collected from infected boxwood plants. In one case, Christmas wreaths sold by a Boy Scout troop in Evansville, Indiana, and purchased from a nursery in North Carolina, were found to be infected with the boxwood blight fungus. Boxwood blight had not previously been found in Indiana and the Indiana Department of Natural Resources (DNR) has asked purchasers to bag and return the wreaths. The DNR will then follow up with those who purchased wreaths next summer to check boxwoods in the landscape for symptoms of boxwood blight. The same wreaths were also sold across South Carolina and buyers have been directed to treat the wreaths as if they were infected and dispose of them by burning or double-bagging and placing in the trash for disposal in a landfill. Unlike Indiana, boxwood blight has been documented in South Carolina, but only in isolated locations. These incidents highlight the need to be exceedingly careful when sourcing holiday greens and other plant products that may harbor diseases like boxwood blight as well as other harmful pests. Also regarding the spread of boxwood blight to new areas, although the most recent finds in Illinois (December 2016), the known infestations that are closest to Minnesota, are certainly a concern, when it comes to long-distance spread, proximity doesn’t really matter because long distance transport by human activities is the biggest threat. For example, the original infestation in Oregon (December 2011), the first detection in the western United States, was ultimately traced to a far-away source, a nursery in Connecticut, and a state where the disease had only been discovered just two months earlier (October 2011) and one of the first two states where boxwood blight had been confirmed almost simultaneously and the first documented occurrences of the disease in North America. Most new infestations have been traced back to the shipment of infested nursery stock and newly planted boxwood plants in landscapes. The recent finds in California (west central CA, south of San Francisco; Kathleen Kosta, Primary State Plant Pathologist, California Department of Food and Agriculture; personal communication) and Washington (Seattle area; Gary Chastagner, Plant Pathologist & Extension Specialist, Department of Plant Pathology, Washington State University; personal communication) are, however, interesting and perhaps a little different as the plants involved were older plants in existing landscapes. Thus far forensic investigation of these infestations has not definitively identified the source of these infestations. It is possible that new plants had recently been added to these landscapes and these areas have recently been experiencing unusually wet weather. Introductions by landscape maintenance personnel could also be a possibility. Some additional research findings related to boxwood blight include: • Thus far, boxwood blight has only been associated with three species within the genus Buxus including Buxus sempervirens, Buxus microphylla (littleleaf boxwood), and Buxus sinica var. insularis, but other species of boxwood (Buxus spp.) are susceptible and none of the species that have been tested appear to be completely immune; in general, Buxus sempervirens and its cultivars appear to be the most susceptible to boxwood blight and resistance in other species is highly variable and often cultivar dependent.

• In addition to boxwood (Buxus spp.), the fungi that cause boxwood blight can infect and cause disease in other members of the boxwood family (Buxaceae) including Japanese spurge (Pachysandra terminalis), a herbaceous, evergreen groundcover used in shady locations in Minnesota landscapes; Allegheny spurge (Pachysandra procumbens), a similar, but lesser known species native to the southeastern United States and sometimes planted in Minnesota landscapes, Emeishan spurge (Pachysandra axillaris), an unusual, evergreen groundcover native to China and Japan with toothed, leathery leaves and fragrant, axillary flowers that is not cold hardy in Minnesota; and sweet box (Sarcococca spp.), a woody shrub with very fragrant flowers that is also not cold hardy in Minnesota; other species may also be susceptible, but have not been tested. • The boxwood blight pathogen has been isolated from asymptomatic plants (plants showing no symptoms) and infected plants can remain symptomless for 3-4 weeks or more; this is a serious problem relative to detecting the presence of infected plants and complicates the ability to detect and prevent the spread when shipping and purchasing plants as these asymptomatic plants and plant material (cuttings and boxwood holiday greenery) can serve as vectors for spreading the disease to new locations. • DNA-based assays involving the artificial replication of DNA to increase DNA levels to detectable levels – PCR or qPCR assays (polymerase chain reaction or quantitative polymerase chain reaction assays) and LAMP assays (loop-mediated isothermal amplification assays) — have been developed and show promise as quick and dirty method for detecting the presence of the boxwood blight pathogens using crude extracts collected from symptomatic and asymptomatic plants; these protocols also have the potential to successfully detect the presence of the pathogens in air and water samples. • The boxwood blight pathogens can survive in the soil and in plant debris and may have the capacity to survive in the soil for up to 10 years or more through the formation of microsclerotia (hardened mycelial masses); research indicates the asexual spores (conidia) can remain viable for up to three weeks; ethyl or isopropyl alcohol, sodium hypochlorite (bleach), phenolic compounds, and quaternary ammonium products can be effective for disinfecting pruners and other tools. • Research to determine the effectiveness of fungicides in controlling boxwood blight continues and has shown that several fungicides may be effective in controlling mycelial growth, sporulation, and spore germination in greenhouse and field studies; chlorothalonil is just one example; remember that fungicides are not cures, most are primarily preventative, but can help reduce spore production and spread; remember that the use of fungicides can mask the disease resulting in symptomless plants that may still harbor the disease and serve as vectors for introducing boxwood blight to new areas; in addition, the use of various sanitation and february 18

cultural practices, biocontrol agents, soil sterilants, and soil surface flaming have been and continue to be investigated as potential control measures with some success. • Whether regulatory actions designed to control the spread of boxwood blight will be implemented by the United States Department of Agriculture — Animal and Plant Health Inspection Service (USDA-APHIS) or by individual states remains unclear; Pennsylvania has, however, become the first state to enact a boxwood blight quarantine (June 25, 2016; http://www.pabulletin.com/secure/data/vol46/46-26/1071. html) and Tennessee is scheduled to become the second state to implement a quarantine on February 4, 2018 (http:// publications.tnsosfiles.com/rules_filings/11-05-17.pdf); these regulations allow the quarantine of any property where boxwood blight is confirmed, restrict the inter- and intrastate movement of any material that my carry or spread the fungus, requires inspection of regulated articles entering Pennsylvania or Tennessee from another state, and requires compliance agreements with growers for production and handling; several other states have implemented voluntary boxwood blight cleanliness programs based on industry-sponsored best management practices and compliance agreements (see below). • Good sanitation and avoiding inadvertent introductions remain best defense; sanitation practices and other actions that can be used to reduce the spread of boxwood blight in nurseries, garden centers, and display gardens and other landscapes include: • Only sourcing boxwood plants, liners, cuttings, and holiday greenery from growers you know and trust and especially growers that are enrolled in state-sponsored boxwood cleanliness/compliance programs. • Inspecting plants for boxwood blight symptoms prior to purchase remembering that asymptomatic plants and plantderived materials can harbor the disease and be a source of infection. • Growing the most resistant boxwood varieties and growing them in full sunlight, with good air circulation, and without overhead irrigation. • Isolating new plant material for at least four weeks away from other plants and shipping areas to allow time for disease symptoms to develop and inspecting these plants weekly. • Avoiding large blocks of boxwood to reduce the potential for significant losses to boxwood blight if it is introduced. • Inspecting boxwood plants and other susceptible species on a weekly basis (scouting), and especially during warm, wet weather. • Wearing clean, disposable shoe/boot coverings (bag and destroy) or carefully removing all debris and soil from footwear between boxwood fields or landscapes and especially locations where boxwood blight is suspected or known to be present. 38

• Wearing clean, disposable Tyveks coveralls (bag and destroy) or laundering clothes between different field and landscape locations and especially those where boxwood blight is suspected or known to be present. • Disinfecting pruning tools and other equipment frequently and between groups of plants or individual plants in landscape plantings. • Regularly removing and destroying fallen leaves and other plant debris; flaming can be useful in eliminating infected plant debris and in sterilizing surface soils. • Not reusing contaminated growing media or containers or sterilizing used containers; ideally, contaminated media should also be sterilized. • Reporting plants suspected of being infected with boxwood blight and having them tested for confirmation. • After testing, destroying diseased plants by burial or burning (if allowed) on site, double-bagging and sending to landfill, and not composting to avoid spread of the pathogen locally and to new areas. • Following the latest developments in boxwood blight prevention and management and incorporating them into production and landscape maintenance programs. • The boxwood blight pathogen is not going away and will likely continue to spread; breeding for resistance is needed and being pursued; the National Arboretum has a significant boxwood collection and continues to obtain new germplasm from native boxwood populations with the hope that this extensive collection (and others) may be an important resource for breeding and selection activities focused on boxwood blight resistance. Shortly after the disease was confirmed in North America in 2011, AmericanHort (formerly ANLA) created a Boxwood Blight Working Group (BBWG) and, together with the Horticultural Research Institute (HRI; the research affiliate of AmericanHort) and the National Plant Board (NPB), developed research-based guidelines for a Boxwood Cleanliness Program based on a set of voluntary best management practices (BMPs) and a compliance agreement that relies on a systematic approach to clean plant sourcing, early detection, and managing and preventing the spread of boxwood blight. These resources were released in 2012. Since the release of this BMP document, ongoing research focused on species and cultivar resistance, fungicide efficacy, biological control, disease mapping and forecasting, vectors for short- and long-distance spread, pathogen survival, mulch impacts, temperature impacts, and heat treatment (cuttings) and an updated set of BMPs (Version 2.0) was developed and released in September, 2017. The updated version is available through the AmericanHort – Knowledge Center website at https://hortknowledgecenter.org/getattachment/ 7068c31f-fee0-4541-bf4a-ac89350be97b/BoxwoodBlightBMPs2017. pdf?lang=en-US and the “Boxwood Blight Compliance Agreement Template” is available at http://sanc.nationalplantboard.org/state-tools/.

Boxwood cleanliness programs designed to prevent the introduction and minimize the risk of spreading boxwood blight have also been developed by several states that have been impacted by boxwood blight including Connecticut (http://www.ct.gov/caes/lib/caes/ documents/special_features/boxwood_blight/guidelines_for_reporting_and_managing_boxwood_blight_in_connecticut_landscapes_version_3_01-27-14.pdf, http://www.ct.gov/caes/lib/caes/ documents/special_features/boxwood_blight/connecticut_best_management_practices_for_boxwood_blight-nurseries_garden_centers_or_dealers_version_2.0_01-27-14.pdf, http://www.ct.gov/caes/ lib/caes/documents/special_features/boxwood_blight/connecticut_ best_management_practices_for_boxwood_blight-for_landscapers_ and_residential_and_commercial_plantings_version_2.0_01-27-14. pdf, http://www.ct.gov/caes/lib/caes/documents/special_features/ boxwood_blight/connecticut_best_management_practices_for_boxwood_blight-positive_production_nurseries_version_2.0_01-27-14. pdf ); Maryland (http://mda.maryland.gov/plants-pests/Documents/ BoxwoodBlight_BMP_2016.pdf ); New Jersey (http://www.state. nj.us/agriculture/divisions/pi/pdf/BoxwoodBMP.pdf ); Virginia (http://pubs.ext.vt.edu/PPWS/PPWS-29/PPWS-29.html, http:// www.vdacs.virginia.gov/plant-industry-services-boxwood-blight. shtml), and others. AmericanHort, a professional entity representing the American horticultural industry resulting from the union of the American Nursery and Landscape Association (ANLA) and the OFA – The Association of Horticultural Professionals in 2014, and the Horticultural Research Institute (HRI) have been leaders in the response to the advent of boxwood blight in the United States. Various boxwood blight research updates and webinars intended to provide nursery and landscape professionals with the most up-to-date scientific information on boxwood blight are available through the AmericanHort and HRI websites (www.americanhort.org and http://hriresearch.org, respectively). Recognizing boxwood blight as an important research priority, the Horticultural Research Institute has also created the Box Blight Fund (BBF) and is working to leverage industry and other sources of research funding to address the boxwood blight threat and promote funding and research in a way that maximizes the value of research funding by avoiding fragmented and duplicative research efforts. Several projects have been funded through these efforts including through the U.S. Farm Bill since 2012. Boxwood blight remains a significant growing threat to boxwood production and use as a landscape plant and should be of concern to all segments of the nursery and landscape industry including nursery, garden center, landscape design, and landscape maintenance professionals and the landscaping public. Keeping this devastating disease out of Minnesota should be a high priority for all concerned. The movement of infected plant material is the number one vector for the spread of boxwood blight and avoiding the importation of infected boxwood plants will be the key to keeping this disease out of Minnesota. Given their nation-wide, and in some cases even larger distribution systems, big box stores may be a special concern in this regard. Be on the lookout for this disease (preventing new introductions is the first line of defense, but early detection and eradi-

cation are also critical if inadvertent introductions occur), propagate existing selections of boxwood only from healthy in-house or in-state source plants and carefully consider the consequences and insure stock is disease free when sourcing new selections of boxwood from out-of-state suppliers. Once again, it would be a shame if boxwood blight finds its way to Minnesota. The reality is that the primary vector of boxwood blight is nursery commerce and the human-mediated movement of infected plant material and other contaminated materials. As a result, this devastating disease will continue to spread unless growers, retailers, landscape service providers, and consumers are aware of the threat and vigilant and proactive in preventing its spread. The development of resistant varieties is the ultimate goal and will hopefully be the answer, but until that happens it is our professional responsibility to be mindful and do all we can to prevent the introduction of spread of this devastating disease.

Cold Hardiness List Now Available The 2018 iteration of the Minnesota Department of Agriculture’s (MDA) Nursery Stock Cold Hardiness List is now available on the MDA website (https://www.mda.state.mn.us/ licensing/licensetypes/nurseryprogram/hardinesslist.aspx).

James Calkins MNLA Regulatory Affairs Manager

The list serves as the legal authority for cold hardiness labeling of Minnesota nursery stock. USDA Cold Hardiness Zones are used for the ratings and the list functions as the primary guidance for identifying false or misleading cold hardiness labeling, which is a violation of the Minnesota Nursery Law, specifically Minnesota Statute 18H.14 (Labeling and Advertising of Nursery Stock). As stated in the Minnesota Nursery Law: (a) Plants, plant materials, or nursery stock must not be labeled or advertised with false or misleading information including, but not limited to, scientific name, variety, place of origin, and hardiness zone as defined by the United States Department of Agriculture, and growth habit. (b) All nonhardy nursery stock as designated by the commissioner must be labeled correctly for hardiness or be labeled “nonhardy” in Minnesota. According to the MDA, whenever nursery stock is labeled for cold hardiness, the hardiness rating on the label must be consistent with the cold hardiness rating published in the MDA Nursery Stock Cold Hardiness List. So long as the correct hardiness rating is included on the label, nothing further is needed. Conversely, nursery stock that isn’t specifically labeled for cold hardiness and isn’t cold hardy in the area in which it is being sold must be labeled “nonhardy.” Note that cultivars are sometimes listed separately from the parent species when their cold hardiness has been documented as being different from the generally accepted cold hardiness level for the species. For cultivars that are not specifically listed, nursery professionals and the public should refer to the species for the appropriate cold hardiness zone rating. MNLA has historically submitted comments as part

Figure 1. Although Minnesota gardeners might wish differently, Aster x frikartii is correctly listed as only being cold hardy to USDA Cold Hardiness Zone 5 on the MDA Nursery Stock Cold Hardiness List; as a result, this aster would need to be labeled as Zone 5 or “nonhardy” when sold in zones colder than Zone 5.

of the annual review process and was pleased to have the opportunity to provide input once again this year. As in past years, MNLA convened a review panel to review the draft list in September and the group’s comments were submitted to the MDA for consideration. We are pleased to note that many of the MNLA recommendations are reflected in the 2018 updated list. The current cold hardiness list will remain unchanged and effective until the list is reviewed and updated once again in September 2018. Please let us know if you would be interested in serving on the MNLA review panel. In past years, a number of MNLA members have wondered whether the MDA Nursery Stock Cold Hardiness List is available in Excel spreadsheet form. This can be obtained from the MNLA by contacting Jim Calkins at jim@mnla.biz. For additional information about cold hardiness labeling requirements for nursery stock, contact Steven Shimek (Minnesota Department of Agriculture, Plant Protection Division) at steven. shimek@state.mn.us or (651) 201-6619.
