FROM THE PRESIDENT

Business Chaos After COVID Timothy Malooly Water in Motion

As I write this article on July 21st, we’ve experienced the fleeting relief of what many consider the most stress-filled year in recent memory, then the easing of most COVID-19 actions, a mild-weather May, extremely hot June and July, and DNR actions to implement its Drought Preparedness Plan that may result in severe cutbacks in outdoor water use that would surely affect the entire Green Industry.

• • • •

Rain? Hardly any.

Staff? Too few; tired, stressed.

New hires? Seemingly, almost extinct.

Vendors? Understaffed, behind schedule, victims of the Suez canal blockage, microchip shortage, skyrocketing commodity pricing, and more…

• Access to capital? Never easier.

• Costs of doing business? Never higher.

• Clients? Many on a spending spree but, with strings attached. Cranky, impatient, ungrateful, entitled.

• Government? There aren’t enough words…

• Opportunities? Well, on some fronts, never better …at least for the moment.

Despite the business chaos that many of us are experiencing this summer of 2021, many of the business professionals among us are taking the opportunities presented to work on their businesses. Attentive operators are culling their client lists, adjusting geographical regions served, reducing the size of their vendor lists, employing technology to help with front and back-office tasks, and researching market value for service industries similar to ours. Personally, our now 31 year-old irrigation installation and service company is downsizing its client base and simultaneously adjusting its approaches to rendering our services. These changes are required to ensure the company will live to see its thirty-second year of business.

Never before has the value been greater of what we can furnish as an industry. Not just because of the apparent demand for our services but, because what we do and how we do it is valuable especially compared to other 10

MNLA.BIZ september 21

spending choices. I’ve included some recent examples of everyday purchases: • a HALF bag of groceries is nearly $60…and $21 of this $60 example is for a small bag of dog food!

• an HVAC invoice included one technician at our Minneapolis office for about 30 minutes, and who merely changed two furnace filters — using OUR filters — and cost us $280.

• $107 for a replacement toilet seat – not even a slow-closing model!

• $181 for a chimney sweep. His tools? A broom, a ladder and a camera.

• Terminix – $639.52/year subscription plus $159 per quarterly visit for exterior pest control ($1,275.52/ year). How long was the tech on site? Less than 30 minutes.

• A simple no-frills business lunch at a sandwich shop – $75.

What’s my point? As an industry we must muster the courage to put to practice what we believe — that we are valuable contributors to our economy — and ecology — and that we play a vital role in the success of our living environment. Practice what you believe. Charge properly for your services and responsibly operate a healthy, vibrant business with relevant offerings, well-maintained equipment, and trained, happy staff with the money to fund and perpetuate your business in the way that you’ve dreamed.

To the practitioners in our industry, take a moment and reflect on your business. Compare what you and your staff

DO YOU BELIEVE IN THE VALUE OF THE SERVICES YOU PROVIDE? I HOPE YOU DO.

must know and do to deliver service. There is a LOT to know! Think about the large investment required for the equipment and inventory that you must have at-the-ready!

Think about the staffing and associated costs and responsibilities for office equipment, software, payroll, insurance, safety equipment, uniforms, training, and development. Oh, and you must operate seasonally, generating the income needed for success in only a few months each year.

Contrast our business realities against what you pay for everyday products and services.

Contrast our business realities against the fees charged by others listed above and a few more: • A typical hourly fee for an accredited auto mechanic is $130, plus parts. They work year-round, and you go to them.

• An electrician is $130 to $180 an hour, plus parts. They work year-round.

• A plumber is $150 to $180 an hour, plus parts. They work year-round.

• Many lawyers are $300-$400 an hour, and you go to them.

• I can’t get a straight answer as to how much is an accountant!

Where are your fees? Are your fees calculated on your costs of doing business, your philosophy and value proposition? Or, are your fees based on “beating some other guy’s price”?

What is your service client base like? Is it made of clients you want and who fit your business approach or with whom you’ve ended-up over time?

Much of what we do is based in skilled labor and what automation is available requires skilled operators too. Truly good practitioners must possess great skill, and the supply today of skilled practitioners is – and likely for the foreseeable future – far outstripped by demand.

Do you believe in the value of the services you provide? I hope you do. If you do then, charge accordingly, put into practice what you believe, build a strong, capable, happy staff, and realize your dreams for your business.

MAKE THE MOST OF YOUR EQUIPMENT with

THE RIGHT WORK TOOL

All photos courtesy of Ziegler CAT

Whether your business is large or small, time is money.

Advertorial

When you’ve committed to have a job finished and need to have a crew on another site, you’ve got a lot riding on being efficient.

Putting yourself in position for success relies on many factors, most of which may be out of your control. The current labor shortages pose a big issue for any company trying to grow and scale, or even maintain a book of business. Increasing speed and efficiency can come in many different forms, but one component that cannot be overlooked is work tools for your equipment.

Power Rake

Power rakes prep and level the ground for seeding while removing unwanted materials. It can help to re-work driveways and gravel. They utilize a rotating drum with carbide teeth to break up the topsoil, while getting rid of unwanted debris.

Machine Compatibility: Compact Track Loaders & Skid Steer Loaders

Rotating Grapple

If you are working on any boulder walls or landscaping, a rotating grapple can make placement much easier, faster, and safer than before. A rotating grapple allows you to not only pick up an object, but also turn and rotate it into the desired position.

Machine Compatibility: Mini Excavators

Grading Blade

While they can come in any variety of shapes and sizes, the specific job tasks that work tools are designed for can increase productivity and offset the initial costs to improve profits.

Making sure that your machines are well equipped for the job-athand is an integral part of offering the best service possible.

When it comes to landscaping there are more than a few work tools that can transform your machines into high-efficiency, money making tools. With the right ones, you can improve productivity and set you on the path for success. Here are a few that rise to the top of the list for landscaping.

Grading Blade

Using a grading blade is a fast and efficient way to get finished leveling. Adjustments are made in the cab on your hand controls and for accuracy; you can add laser-guided GPS to make sure you are getting the job done right.

Power Rake

Tiller

A tiller has double-edge tines lined with tungsten for durability and can be easily tear through a variety of hardened materials.

The tiller is designed to break up and mix soil to create seedbeds, stabilize and level soil. Setting the workable depth is easy with adjustable shoes, which helps to create consistent work in varied conditions.

Machine Compatibility: Compact Track Loaders, Skid Steer Loaders

Machine Compatibility: Compact Track Loaders, Skid Steer Loaders

Mulcher

Speed up your land clearing by putting a mulcher to work. Mulcher’s are known for their durability and toughness when it comes to getting difficult jobs done. They are designed for high-performance cutting and mulching undergrowth (pictured on left).

Machine Compatibility: Compact Track Loaders, Skid Steer Loaders, Mini Excavators

Auger

If you are digging holes by hand, you are doing it wrong! An auger makes quick work of a variety of ground conditions and saves you time when you are planting trees, or putting in deck footings. If you are digging a large number of holes, in instances like putting up a fence, this is a real time-saver.

HEARTSAVER® CPR AED TRAINING Training provided by CPR Professionals CPR training is important. It can save your life, a loved-one’s life, a co-worker’s life, or even a stranger’s life. CPR training helps people learn the skills and develop the confidence to provide CPR when encountering a cardiac arrest victim.

And while AEDs can be used by the public regardless of whether the responder has been trained, even minimal training improves performance, timeliness, and efficacy. This interactive, hands-on training is intended for anyone with little or no medical training who needs a course completion card for job, regulatory (e.g., OSHA), or other requirements. This training can also be taken by anyone who wants to be prepared for an emergency in any setting. Everyone completing the training will receive a two-year certification.

THERE’S NO “I” IN TEAM:

USING CULTURE, HR STRATEGY AND PEOPLE PRACTICES TO STRENGTHEN YOUR BUSINESS Kristen Ireland and Erin Mies, People Spark Consulting Businesses typically approach HR in one of two ways. Many look at human resources responsibilities as compliance officers, a necessary evil, a have-to-do…. These businesses are looking for the safe routes, the ones that keep them out of legal trouble. They are not truly leveraging the power of their employees: their team. They are playing NOT to lose.

Other businesses know that their success depends on their team. They know that whether customers return depends on the interactions with their employees. They work with their employees to drive business success, they are an employer of choice and they are able to retain their high performing employees, even in a tight labor market. These are the businesses that are taking aim for their target. They are playing to WIN. Playing to WIN doesn’t have to be hard or take a lot of resources. It’s not about trendy perks or game rooms. It’s having employees who know what is expected of them, managers that provide direction, clarity, and coaching, and having goals and rewards aligned to drive business results – and they do exactly that.

In our interactive, 2-part session, we will share a variety of simple and practical tools business owners and managers can put to work in organizations of any size, and discuss the important role they play in making things stick. In doing this, leaders develop the culture and reputation that not only attracts great talent, but that keeps it, too.

• Session 1 - Culture, Compliance Basics, and Recruiting & interviewing • Session 2 - Hiring/Onboarding, Managing Performance, Engaging & Retaining Your Employees By the end of the workshop, attendees will better understand and know how to: 1. More clearly set your business direction, clarify your team’s goals, and get your team going in the same direction.

2. Reduce your organization’s risk for preventable lawsuits and other third-party actions using practical tools and guidance.

3. Minimize avoidable HR issues like bad hiring decisions.

4. Confidently address performance concerns with employees.

5. Improve employee communications to increase high-performing employee retention.

When it comes to human resources, are you playing to WIN or are you playing NOT to lose?

GOVERNMENT AFFAIRS

Green Industry Advocacy in 2021 and Beyond Forrest Cyr

MNLA Director of Government Affairs

Minnesota’s Green Industry is a respected voice at the Minnesota State Capitol, advocating for pro-business, pro-environment policies.

In 2021, MNLA staff and volunteers worked tirelessly to secure important state funding for key programs throughout Minnesota, and continued to lobby for bills that benefit MNLA’s membership and the Green Industry. To help achieve these goals, support of legislative allies through the Minnesota Green Industry Political Action Committee (MGI-PAC) should be a top priority. Fundraising from Green Industry members and leaders is essential to this effort. As the electoral arm of the Green Industry’s advocacy campaigns, the MGI-PAC supported candidates for reelection statewide in 2020, with 93 percent of supported candidates winning reelection.

Our legislative successes in 2021 include securing funding for numerous programs with direct impacts on MNLA members statewide, including funding for Emerald Ash Borer mitigation, continued funding for the Minnesota Invasive Terrestrial Plants and Pest Center (MITPPC) included in the Environment and Natural Resources Trust Fund (ENRTF), and other important LCCMR funding projects seeking final legislative budget approval. Additionally, MNLA helped stop bills that could negatively impact industry members and saw progress on multi-year legislative priorities including duty to defend reform and backflow reform.

Working with a dedicated group of volunteer experts from a variety of different Green Industry specialty fields, the importance of the industry is known to legislators, stakeholders, and the public through sustained communication, advocacy, and networking. This visibility serves

the members well and positions the Green Industry to succeed for years to come. MGI-PAC, through its bylaws, contributes to Minnesota legislative candidates on a nonpartisan basis, supporting those who support the green industry in Minnesota. A strong, well-funded PAC, just like an engaged membership, demonstrates how invested the members of the green industry are, and how closely they

TO STRENGTHEN OUR GOVERNMENT AFFAIRS PROGRAM AND PROMOTE POLICIES VITAL TO THE SUCCESS OF THE GREEN INDUSTRY, THE MGI-PAC SHOULD BE A PRIORITY FOR THE ASSOCIATION’S MEMBERSHIP AND VOLUNTEER LEADERSHIP. watch policy decisions in Saint Paul. Individuals know that when giving their hard-earned money to the PAC, their contributions will only go to candidates who are friends of the green industry.

We can do more to strengthen our advocacy outreach; advocacy is a year-round endeavor. Through both grassroots and electoral activities, Minnesota’s green industry can influence policy not just during legislative sessions, but throughout the calendar year. The Minnesota Green Industry PAC should be central to this effort.

WIRE BASKET Impacts of

RETENTION AND REMOVAL ON WHOLE TREE STABILITY AND LONG-TERM GROWTH Richard J. Hauer, Andrew K. Koeser, Jason W. Miesbauer, Jeff Edgar, and David Kleinhuizen Reprinted with permission of the Horticultural Research Institute’s peer-reviewed research publication Journal of Environmental Horticulture.

Abstract: When balled-and-burlapped trees are planted, a decision must be made regarding whether the wire basket, burlap, and other packing materials should be removed (completely or partially) or retained. While past research has failed to show a significant impact of either approach with regard to initial growth and establishment, many professionals still question whether a decision to leave the wire basket intact at planting will have longer-term impacts to tree health and stability. In this study, we revisit two nursery trials first initiated in 2011 and 2012 to assess the impact of burlap folding, and full wire basket removal, partial removal, or retention on tree growth and root anchorage five to six growing years after planting. We found that neither stem caliper (min P = 0.249) nor twig elongation (min P = 0.297) differed among removal treatments with the Norway maple (Acer platanoides L.) and ‘Skycole’ honeylocust (Gleditsia triacanthos L. var. inermis) trees used in this study. Similarly, we were unable to detect any differences in rooting strength among the removal treatments tested (min P = 0.154).

These results serve as further evidence that wire baskets are not a cause of early tree mortality or instability.

Index words: Arboriculture, biomechanics, growth and longevity, nursery production, static-pull test, transplanting, transplant shock.

Species used in this study: Norway maple (Acer platanoides L.); ‘Skycole’ honeylocust (Gleditsia triacanthos L. var. inermis).

Significance to the Horticulture Industry Wire baskets have played a critical role in the mechanization of field-grown nursery tree production. Despite their prevalence, there is still a lack of industry consensus regarding what should happen to this packing material (and other materials like burlap) at planting.

In this study, we found no differences in tree survival or growth five to six years after transplanting when trees were planted with wire baskets intact, partially removed or fully removed and treated burlap folded or unfolded. Moreover, wire basket removal or retention did not influence rooting strength when trees were pulled to assess whole-tree

anchorage. This paper adds to the small, but growing body of literature that directly addresses best practices for planting balledand-burlapped trees.

Introduction The period of time associated with planting and establishment is one of the most challenging in an urban tree’s life (Hilbert et al.

2019). For balled-and-burlapped trees, root loss, water stress, rootball disruption, and changes in below- and above-ground environment all contribute to a period of increased likelihood of mortality and decreased growth known as ‘‘transplant shock’’ (Koeser et al.

2009, Struve 2009, Levinsson 2013). Among the list of potential stressors associated with balled-and-burlapped tree transplanting, one persists despite a general absence of evidence to support its validity. This is the belief that failure to remove at least some of the packing (i.e., wire basket, burlap, twine) will hinder establishment or even lead to premature tree death (Appleton 2015).

thought exist on whether to remove or not to remove wire baskets, burlap, and twine at planting (Appleton and Floyd 2004, Cregg 2009, Kuhns undated, Weigel 2019, Gilman 2020). While professional opinions differ, the research on the topic has remained relatively consistent. The first peer-reviewed work on the subject was an observational account by Lumis and Struger (1988). In this brief article, the authors excavated 11-year-old willow (Salix spp.) to document the regrowth of vascular tissue over wire from a basket wire which was partially girdling the roots (Lumis and Struger 1988). Four years later, Goodwin and Lumis (1992) conducted a controlled greenhouse experiment where they used floral wire to girdle (fully or partially) potted green ash (Fraxinus pennsylvanica Marshall) grafted plants, hackberry (Celtis occidentalis L.) seedlings, as well as hybrid poplar (Populus angulata X plantierensis) liners. For the first two species, the researchers found no significant difference in growth (whole-plant dry weight) when comparing the partially and fully girdled treatments against the ungirdled control (Goodwin and Lumis 1992). Similarly, the authors failed to detect differences in caliper and whole-plant dry weight for the hybrid poplar tested (Goodwin and Lumis 1992).

While an improvement from the earlier work, Goodwin and Lumis (1992) were quick to point out that it might be difficult to draw parallels between the findings of their study (conducted on very young specimens over the course of one growing season) and the potential health impacts associated with wire basket girdling on maturing trees.

More recently, Koeser et al. (2015) conducted a controlled experiment in two commercial nursery environments, assessing the impact of wire basket removal (full and partial) and retention on the short-term health and survival of larger-caliper 5 to 9 cm (2 to 3.5 in) Norway maple (Acer platanoides L.) and ‘Skycole’ honeylocust (Gleditsia triacanthos L. var. inermis) trees. In this study, the authors failed to detect any significant differences in survival, twig growth, or caliper growth after two to three growing seasons (Koeser et al.

2015). Similarly, Klein et al. (2019) failed to detect differences in survival and growth for 45 ‘Autumn Purple’ white ash (Fraxinus americana L.) trees subjected to two levels of wire basket and burlap removal (i.e., intact or full removal) or spade transplanting (i.e., no packing materials used) after nine years.

The aim of this study was to revisit the trees from the Koeser et al. (2015) study and quantify the effects of removing all, some, or none of the wire basket, twine, and burlap that cover soil of tree root balls over a longer period of time.

We set out to determine if the growth of landscape trees differ with different treatments that replicate three common approaches to removing materials that cover root balls. We also tested if the stability of trees after establishment (e.g., five to six growing seasons post planting) differed when subjected to static pull testing.

see Koeser et al. 2015). Both study locations were commercial tree nurseries in the upper Midwest (United States) with differing soil textures and climates. The first study site was located in Manitowoc, WI (lat. 44° 5´ N, long.

87° 39´ W, USDA Hardiness Zone 5b) and was planted on June 28, 2011. The second study site located in Forest Lake, MN (lat. 45° 17´ N, long. 92° 59´ W, USDA Hardiness Zone 4b) was planted on May 10, 2012. These locations were selected to provide an intentional spatial and temporal variability (with planting and harvest dates staggered over seasons) to capture contrasting growing environments.

Soils were a Keowns very fine sandy loam (USDA 2019) in Wisconsin (3.2% OM and 7.3 pH) and a Lino variant loamy fine sand (USDA 2019) in Minnesota (1.5% OM and 6.2 pH). After planting, trees were monitored for five (Manitowoc) or six growing seasons (Forest Lake) before being destructively pull tested to gauge rooting strength. The final measurements occurred on September 25, 2015 at the Manitowoc, WI site and on May 30, 2018 at the Lake Forest, MN site.

Study plants. Two commonly planted shade tree species, ‘Skycole’ honeylocust (Gleditsia triacanthos L. var. inermis) and Norway maple (Acer platanoides L.), were selected for comparison in this study. Both species were field grown and harvested as balled-andburlapped stock using standard tapered wire baskets constructed from 10.5 gauge wire following nursery standards at the time of the study start (ANLA 2004). Norway maple were 5.0 cm to 6.5 cm (2.0 in to 2.5 in) in caliper at the Wisconsin site and 7.5 cm to 9.0 cm

Fig. 4. Average bending stress for ‘Skycole’ honeylocust (Gleditsia triacanthos L. var. inermis) and Norway maple (Acer platanoides L.) trees pulled to one degree inclination. Trees received one of three transplanting treatments: intact (wire basket and balled-and-burlapped packing materials were not removed), partial removal (removal of the top third of the packaging materials), and full removal (all packaging materials removed). Bars represent standard error, honeylocust n=30 and Norway maple n=26.

(3.0 in to 3.5 in) in caliper at the Minnesota site at the time of planting. Honeylocust were 5.0 cm to 6.5 cm (2.0 in to 2.5 in) in caliper at the time of planting. A 76-cm (30-in) diameter wire basket was used to transplant the honeylocust at both sites and the Norway maple at the Wisconsin site. The larger Norway maple at the Minnesota site was placed in 91-cm (36-in) diameter wire baskets during transplanting. The wire hole size for the 76 cm basket was 15.2 cm (6 in) tall by 15.2 cm (6 in) wide, basket height was 45.7 cm (18 in), with a 43.2 cm (17 in) bottom rung and 76.2 cm (36 in) top rung (model 30 CBT, Dayton Bag & Burlap, Dayton, OH). The wire hole size for the 91 cm basket were 15.2 cm (6 in) tall by 21.0 cm (8.25 in) wide, basket height was 61 cm (24 in), with a 40.6 cm (16 in) bottom rung and 91.4 cm (36 in) top rung (model CBV36CG, Cherokee Manufacturing, South St Paul, MN). Natural burlap was 0.37 kg.m 3 (10 oz.yd 3) weight treated with copper sulfate, 0.2% (Cherokee Manufacturing, South St Paul, MN). Trees were dug from and planted in the same soil type at each study location.

Experimental treatments. Sixty (60) trees in total were used for this study. At each site, 15 trees per species were randomly assigned one of three treatments for 5 replications per treatment. The treatments were as follows: 1) wire basket and natural burlap fully intact (intact); 2) top third of the wire basket removed and the natural burlap cut and folded down as low in the planting hole as possible (partial removal); and 3) wire basket completely removed and natural burlap folded down in the hole below

the root ball (full removal) (Koeser et al. 2015).

For all treatments, any twine wrapped around the base of the trunk was removed to prevent stem girdling. When planting trees in the full removal treatment group, the bottom of the basket was removed prior to placing the tree in the planting hole. This left the sides of the tapered basket intact to support the root ball until the tree was completely situated in the bottom of the planting hole. The remaining wire basket was then removed, and the burlap was loosened and folded down to the bottom of the hole. All trees were assessed to ensure the root-stem transition zone (RSTZ) was planted at or slightly above the final soil grade to avoid issues of deep planting. Planting holes were dug with a tree spade attached to a skid steer (Wisconsin site) or u-blade attached to a skid steer (Minnesota site). Before planting, these holes were widened with a hand shovel to a width of 1.5 times the root ball diameter to allow access for wire basket removal and burlap loosening as noted above. Trees were transported from their harvest location to the planting holes via forks attached to a skid steer. Final soil backfilling was done by shovel and the soil was tamped lightly to reduce air gaps. Trees were later watered by hand to wet the soil and no supplemental irrigation occurred during the study.

Growth measurements. Stem caliper was measured above the graft union at 15.2 cm (6 in) from the ground. Caliper was initially measured with a digital caliper and the mean of two measurements (North-South and East-West) used, and later (last two years of study) caliper measurements were taken with a diameter tape. The caliper measurement location was marked annually with a waxed pen or black Sharpie pen. Annual elongation was measured for three twigs on each tree from terminal shoots of the lowest three sun-exposed main branches and the mean of these values were used for analysis. Growth measurements were taken at or near the end of each growing season.

Static pull testing. Static pull tests are a standard method and were conducted to evaluate the effect of wire basket removal or retention on tree stability (Peltola 2006).

To measure tree tilt, an inclinometer (model DOG2 MEMS, TE Connectivity, Schaffhausen, Switzerland) was secured to the tree base at a height of 15 cm (6 in), directly above the root flare. A 2,268 kg (5,000 lb) capacity winch was secured to earthmoving equipment available onsite and used to exert the pulling force needed for the pull tests. A sling was

then hitched around the tree at a height of 1.4 m (4.6 ft) and the winch was positioned at a uniform distance from the tree. A 4,536 kg (10,000 lb) capacity load cell (SSM2-N5-10K; Interface Inc., Scottsdale, Arizona, U.S.) was secured in-line between the sling and winch cable to measure the force required to pull the trees to 18 of tilt. After the first pull, the tension on the winch cable was released and trees were allowed to return to their initial resting position as indicated by the inclinometer. Pull tests were repeated two more times for a total of 3 pull tests. All inclinometer and load cell readings were sampled at a rate of 20 Hz using a 16-bit data acquisition system (National Instruments Corporation, Austin, TX, U.S.) while being observed and archived on a laptop computer running engineering software (LabView v.13.0.1, National Instruments Corporation, Austin, TX, U.S.). Relative differences in rooting stress were compared in terms of bending stress. Bending stress (r) was calculated using the equation: σ = 32P1 cos θ/πD3 (Eq. 1)

where P = the force (averaged over 3 pulls) required to reach 1 degree of inclination, θ = the angle of winch cable from horizontal, 1 = trunk length from the ground to the height of sling attachment, and D = trunk diameter measured 15 cm above ground level (height of inclinometer attachment, which was directly above the root flare).

Design and analysis. At each location, trees were grouped by species and planted in rows on an approximate 3m (10 feet) spacing.

The three treatments were arranged by species grouping in a completely randomized design. Final caliper growth was analyzed separately for each species using Analysis of Covariance (ANCOVA) with initial caliper, site, and treatment included as covariates (R Core Team 2018). Similarly, twig elongation was analyzed separately using ANCOVA with site, treatment, and growing season as covariates. Bending stress was assessed as a linear regression using the lm() function in R (R Core Team 2018). The data from the Minnesota site was initially modelled separately as soil moisture data was collected at this location, but not at the Wisconsin site. After initial analysis showed soil moisture did not influence the analysis (P 0.262), the covariate was dropped, and all data was pooled together for both sites. Our final model for bending stress included species and treatment as covariates (site was dropped given non-significance). All underlying assumptions for the statistical models used were assessed using september 21 MNLA.BIZ

Results and Discussion We used tree growth and stability (as assessed through a pull test) to attempt to elucidate any differences among treatments. Over the course of the study, we found no evidence of differences among treatments for any of our responses (e.g., twig elongation, caliper growth, and bending stress). All honeylocust trees survived at both sites. Rodent-induced mortality occurred on Norway maple in Minnesota (1 tree) and Wisconsin (3 trees). Average annual twig elongation was similar for all three treatments for honeylocust (P = 0.2971) and Norway maple (P = 0.7821, Fig. 1). Honeylocust (25.8 cm; 1.1 SE) had greater twig elongation than with Norway maple (12.7 cm, 1.1 SE). Twig elongation differed by site for the honeylocust trees (P < 0.0001) but not the Norway maple (P = 0.2545). Honeylocust trees had 35% greater mean twig elongation in Minnesota (29.7 cm, 1.5 SE) than in Wisconsin (21.9 cm, 1.4 SE). The measurement season was also significant for both species (P < 0.0001), with reduced twig elongation being observed in the two to three years following transplanting.

As with twig elongation, mean caliper growth did not differ by treatment for honeylocust (P = 0.2486) (Fig. 2) or Norway maple (P = 0.6120) (Fig. 3) during the study period.

Honeylocust caliper increased from 5.54 cm (0.08 SE) at the end of the first season to 9.83 cm (0.22 SE) at the end of the sixth season.

Average caliper for the Norway maple trees increased from 7.40 cm (0.32 SE) at the end of the first season to 16.47 cm (0.32 SE) at the end of the sixth season. A significant (P < 0.0001) site difference occurred which was the result of one additional growing season at the Minnesota site. However, no significant interaction was detected between site and treatment for honeylocust (P = 0.4314) or Norway maple (P = 0.5509).

The full multiple regression (F(3, 52) = 17.73, p < .001, AdjR2 = .65) showed no effect of removal treatments. Neither partial removal (P = 0.154) nor full removal (P = 0.997) offered any discernible benefit over our intact treatment with regard to bending stress (i.e., rooting strength). Similarly, no site-related differences in bending stress were detected (P = 0.922). The bending stress for honeylocust pulled to 1 degree was greater than that of the Norway maple (P < 0.001; Fig. 4).

Findings from this study offer additional 32

empirical observation of the effect of retention (intact) or partial- to-full removal of balledand-burlapped packing materials on the survival and stability of transplanted trees.

We found that regardless of treatment, tree growth measured through twig elongation and stem caliper were similar. Our findings are consistent with our earlier results (Koeser et al. 2015) in which the growth of these same trees was assessed for the first two to three growing seasons after planting. It is also in line with the research by Klein et al. (2019) who found no difference between partial, or full removal of balled-and-burlapped packing materials nine years after planting. This study and the work of Koeser et al. (2015) and Klein et al. (2019) studied angiospermous trees. We do not know if coniferous trees will respond similarly to results from this current study.

It is possible that if this study or others (Lumis and Struger 1988, Goodwin and Lumis 1992, Klein et al. 2019) were allowed to progress for a longer period (e.g., 1 to 2 decades or more) that an effect could occur.

This is a valid and testable argument, and we know of no controlled multi-decade studies on this question. The fear that wire can girdle tree roots and that tree root penetration is affected by burlap are presented as justification for removing balled-and-burlapped packing materials in order to enhance transplant growth and survival (Kuhns 1997, Appleton and Floyd 2004). However, we believe that is not the case based on Lumis and Struger (1988) who found root embedding of wire baskets after 7 years in ‘‘Tristis’ weeping willow trees. Similarly, Kuhns (1997) observed that Norway maple roots were able to penetrate burlap. As the years following transplanting are generally considered some of the most tenuous in a tree’s life (Hilbert et al. 2019), the results of this and other studies on wire basket removal may ultimately be indicative of longer-term survival.

When planting trees, there are many considerations beyond the debate with removing packing materials. Planting depth is perhaps of greater concern (Miesbauer et al. 2019).

Tree planting with the RSTZ below the soil surface may result in tree roots growing toward the soil surface and resuming lateral growth at a direction away from or towards the tree stem. A root that encircles a tree stem can later through stem and root growth result in girdling and tissue compression, resulting in tissue dysfunction (Hudler and Beale 1981). The effect of dysfunction from stem girdling roots can lead to the gradual

decline of trees one to two decades post planting and whole tree failure for damaged and decayed stem tissue ( Johnson and Hauer 2000, Arnold et al. 2007, Gilman et al. 2010, Watson and Hewitt 2012, Harris et al. 2016).

Post-transplant watering is also vital to plant survival and establishment (Gilman 2001, Gilman et al. 2013). Post-transplanting tree watering led to greater tree survival and greater root growth in Quercus virginiana Mill.

Removal of burlap is suggested as it can wick water away from the rootball. However, no research is known to substantiate this claim and this topic should be studied (Gilman 2020).

If packing materials are removed, then staking a tree might be needed. Staking a tree might also be needed for trees without packing material removal. Interestingly, the removal of packing materials resulted in several trees that had full or partial removal of packing material to partially lean during a moderate wind storm approximately 18 m/s (40 mph) in strength a few days post planting in the Minnesota experiment. The trees were straightened and no effect on the experiment was observed.

But this observation suggests a BMP for planted trees is to stake those that had packing materials removed. There are many ways to stake a tree (Appleton et al. 2008). A basic premise is the tree should still retain some stem movement and staking materials attached to the tree stem should not lead to stem girdling.

Root severing can affect tree stability and Smiley (2008) found in willow oak (Quercus phellos L.) that when root severing occurred at least 3 times the stem diameter or more away on one side, there was no difference in the force required to move a trunk to 1° of tilt. In this study trees had roots severed at approximately 5 to 7.5 times the stem diameter away when harvested (data not shown). Except for the initial wind tilting post planting at one site, tree roots then grew for 5 to 6 years and when subjected to static mechanical force, only a difference in tree species was detected. Gilman and Wiese (2012) found the cross-sectional area of roots was correlated with greater stability.

They also found that correcting root defects (e.g., circling roots) was important to promote tree stability in container-raised trees two years following planting. This study used balled-andburlapped harvested trees that were planted as bare root liners with no known circling root issues and trees were harvested and soil removed so the RSTZ was at the surface. Observation of several root systems lifted with a u-bladed at the end of the experiment showed no visual observations of root defects. The burlap was

also well decomposed with little material observed at the end of the experiment.

The root system configuration of the species in this study differ in rooting depth.

Honeylocust have a wide spreading and deep rooting habit that profusely branches (Blair 1990). By comparison, Norway maple has a shallow root system (Gilman and Watson 1993). Thus, this fact may explain the difference with Norway maple trees requiring less force to pull to 1° of tilt. At the soil surface, both honeylocust and Norway maple had similar trunk flare diameter (Hilbert et al. 2020).

Results from this study will likely not put to rest whether a practitioner should remove packing materials at planting and by not doing such leads to premature plant death. The results from this study showed no difference regardless of treatment. These findings are also consistent with three other studies that showed the same result. Tree planting specifications should clearly describe what is to be done. Point in case is whether to remove packing materials or not. One could argue that the length of this study and others cited in this paper were too short and perhaps a different finding after several decades would result.

Clearly our study was not designed to answer that question, but addressed the effects during establishment and within a few years after transplant establishment occurred. The installation and development of a controlled study is recommended to address and answer this generational question. But until then, we know of no controlled studies that have shown that removing or retention of packing materials is detrimental to plant establishment, growth, and survival. We are not discounting the belief of practitioners that a tree with a wire basket not removed has a lower long-term survivability relative to trees that removal occurred. But we are saying that the results to date do not support such anecdotal beliefs. We also argue if this is the case then this anecdotal conclusion would likely and commonly result in tree death above normal mortality with landscape trees. Interestingly, the authors of this paper differ in the opinion on to remove or not remove wire baskets at planting. The results of this study also offered no evidence to change one’s practice.

Rather it raised an important point that in science, colleagues with differing opinions can use a scientific method to test beliefs that ultimately are tested with the scientific method.

FACE HAZARDS IN SUBURBAN LIFE Faith Appelquist Tree Quality LLC

A healthy bur oak with fencing to protect the roots from equipment and animals.

Left: Armillaria is killing this bur oak because the site has gotten too wet

All photos: Faith Appelquist

Above: Armillaria honey fungus growing on the root of an oak tree surrounded by irrigated turf grass.

Although they look indestructible, oak trees have a weakness. You can kill them with too much water. The fittest oaks learned to survive through prolonged summer droughts. That is their strength. They are hardy trees that have weathered fire and pestilence, flood, and drought. But they may not survive being part of the modern suburban landscape.

Their weakness shows up when turfgrass is planted and irrigation surrounds them. Summer watering to maintain green lawns and lush flower beds under these trees predisposes them to root rot which will cause decline and death.

Armillaria is a root rot fungus that thrives in the soil under consistently moist conditions. Armillaria can develop slowly, and symptoms may not appear until the fungus is well established. Armillaria is usually a secondary problem, only killing roots when a tree is stressed or dying. Affected trees usually show a general decline in vigor over many years. Sometimes trees that look healthy will suddenly wilt and die in a matter of weeks. The above ground symptoms are similar to other root problems, like construction damage.

Tree owners should be aware that roots extend far beyond the canopy. It is estimated that tree roots can be found at a distance two and a half times the height of the tree. These critical factors should be considered when working around oaks:

You may have to choose between having healthy oaks or a green summer lawn in that part of your yard.

• First, turn off the water. Let the soil dry out. Armillaria is sensitive to drying and grows most rapidly under wet conditions.

• In most cases it`s preferable not to plant under the oak canopy. It should be avoided if at all possible.

• Don’t try to grow plants with high water demands under your oaks, like hydrangea for example.

• Don’t raise or lower the soil level in the root zone of existing oak trees; this can significantly alter the amounts of air and water accessible to the root zone and cause damage to the roots themselves.

• Don’t disturb the soil in the root zone; that means no grading, digging, trenching, paving with asphalt or concrete, roto tilling, or irrigating.

Majestic old oaks can add much to the value of your home and the pleasure of your yard. It is well worth understanding how to keep them healthy.

MDA UPDATE

Cold Hardiness Matters Kimberly Thielen Cremers Plant Pest Regulatory and Mitigation Section Manager Plant Protection Division Once again, the Minnesota Department of Agriculture (MDA) is taking comments on the cold hardiness list posted on the department’s website: www.mda.state.mn.us/cold-hardiness. This list has been developed over many years with the input of several industry, university, and trial garden experts. The review process takes place in September and is finalized in October for the upcoming growing/shipping season.

As new plants are introduced, trial garden assessment is critical to determine what cold hardiness zone is appropriate. A recent request regarding a new rose in the “Knock Out” series came with trial data from the University of Minnesota West Central Research and Outreach Center (WCROC) in Morris, Minnesota. This is the gold standard: trial data from the northern edge of Zone 4 in Minnesota.

State statute prohibits plants from false or misleading labeling. The minimum USDA cold hardiness zones are listed. Labeling cannot be a lower or colder zone, but conservative higher or warmer zones can be used.

Why is cold hardiness so important? In Minnesota, the answer is simple: it gets cold here. Loss of plant material to winter cold is common, even for plants considered cold hardy in the USDA zone in which they are growing. This becomes more important to fruit trees and plants as flower buds can be killed. This author is seeing the second straight year with no apples or plums due to a late May frost. Global climate change seems to be causing extremes in temperature and precipitation. Instead of cold hardiness zones creeping northward as some would have you believe, we have seen more fluctuations that kill flower buds along with marginally cold hardy plants. Of course, there are many site conditions the influence cold hardiness, and gardeners like to see if they can push the envelope. The MDA list does not attempt to limit what is sold, only that accurate labeling alerts the buyer to possible cold hardiness.

Each spring, dormant packaged plants show up in March at big box retailers trying to entice buyers to make early plant purchases. Many of these plants have cold hardiness labeling violations; claiming Concord grape is hardy in Zone 4 when the panel of experts reviewing the list concur that they are Zone 5 plants. This year inspectors found six violations of plants mislabeled for hardiness. Plants are removed from sale pending correct labeling.

If you are interested in providing recommendations for additions or changes to the MDA list, send them to Steven Shimek (steven.shimek@ state.mn.us) along with supporting documentation.

2021 HAS CERTAINLY BEEN A TOUGH SEASON FOR OUR COOL-SEASON GRASSES. With the heat, humidity, and lack of moisture throughout much of the season, homeowners are experiencing several compounding issues and these issues can be confused. One noticeable theme is mistaking drought-stressed turf with diseased-turf, specifically ascochyta leaf blight.

VIEW-SAVER

Ascochyta leaf blight is a fungal pathogen that negatively affects the leaf tissue of common cool-season grasses. This will show as fungus that affects the foliar leaf tissue.

• Signs (visual evidence of the actual disease pathogen): Mycelium and tiny yellow/brown pycnidia (fruiting bodies) on the leaf blades, which often needs a hand lens to view.

• Symptoms (changes to plant caused by the disease): • Irregular patches of straw-colored grass, usually seen in hot and sunny areas of the lawn first.

• Bleached/needle point tip of the grass blades – discoloring from the tip down. This can affect the whole leaf blade or can show as a pinched grass blade with banding between the straw-color and the green color.

The lawn discoloration can be confused with drought-stressed grass — it looks very similar.

Why does it occur?

The disease triangle needs a host (grass plant) + pathogen (ascochyta) + environment (hot/humid/dry weather followed by cool/moisture).

The pycnidia can survive on dead grass clippings, as well as within the thatch layer. These fruiting bodies can spread with water, but can be worse on lawns that are experiencing drought. The ascochyta pathogen tolerates heat and dryness. Newly cut grass creates an opening or wound for the pathogen to infect the leaf tissue; thus, the discoloration will start from the leaf tip down. september 21 MNLA.BIZ

Organic Lawn Care by LUNSETH

LEAF BLIGHT

This disease can happen in two ways:

1. The environment is conducive for disease signs to appear. This would include

weather that is hot/humid/dry followed quickly by moisture and cooler temps.

2020 was particularly bad, as we had several rainstorms that came in overnight with cooler temperatures. The days then warmed and became hot and humid, which allowed the disease symptoms to appear almost overnight. The fruiting bodies are resistant to drought and high temperatures, thus why the disease can thrive when these environmental conditions exist.

2. The homeowner creates the environment

by overwatering. Light, frequent watering

will encourage this disease, especially if done in the later evening or nighttime. Increasing the water because this disease looks like drought-stress will exacerbate the symptoms. This disease is also interesting because it will be worse on lawns that are drought-stressed to begin with. Adding water to the lawn inappropriately will spread the disease.

What you can do: 1. First, relax. This disease affects the foliar leaf blades, but does not negatively affect the crown of the grass plant. Once environmental conditions improve, the plant will resume sending out green grass shoots. If the homeowner is overwatering, then turning off the water will allow the grass to improve.

2. Don’t let the lawn get into a drought-

stressed state. A healthy lawn will better withstand the pathogen pressure.

Raise mowing height and mow less frequently, as this disease can follow mower tracks.

Overseed with more resistant grass varieties. This disease likes Kentucky bluegrass hosts, so overseeding with tall fescue would be a good option.

Aerate annually in the fall to reduce thatch and maintain proper water drainage.

Turn off water if watering more than 2x per week. Water deeply and infrequently, so that the lawn is saturated with 1” of water at the same time. Do this 1x per week, or for sandy soils and extreme drought situations, 2x per week.

Collect grass clippings to reduce spread (this does not affect severity).

Don’t overfertilize.

Maintain even soil moisture levels, if possible.

2021 has posed an especially bad year for drought. However, some of these situations are not drought, but ascochyta leaf blight.

Taking a look at the watering schedule and examining the grass leaf tissue can help with diagnosing this issue. If you know you have the pathogen, then the two options to help are to 1) change the host or 2) change the environment. Sometimes the only thing you can do is be patient and wait for the weather to improve. More frequent, severe, and drastically changing weather events allow this disease to thrive. If global warming creates such events, it may be safe to say that this may be a disease that we will see more often.

When the water gets choppy, are you able to adjust course or will you get caught in the storm?

MNLA Regulatory Update Palmer Amaranth (Amaranthus palmeri) Confirmed in

GOODHUE COUNTY

James Calkins

MNLA Regulatory Affairs Manager

PALMER AMARANTH

The suspected find was reported to the MDA by

a crop consultant and the MDA has subsequently confirmed Palmer amaranth infestations in two corn fields that are part of the same farming operation. A herbicide treatment stunted but did not kill the Palmer amaranth plants so they were removed by hand to prevent seed production. Further scouting by the MDA did not reveal any additional Palmer amaranth infestations in neighboring fields and the source of these infestations remains unknown at this time. The MDA is, however, continuing to investigate potential sources and is working with the landowner and others in an effort to detect and eradicate any Palmer amaranth plants that may appear this year and, as it has for other infestations, will continue to monitor these and surrounding fields in future years with the goal of ensuring that these infestations are contained and hopefully eliminated.

Palmer amaranth was first discovered in western Minnesota in Yellow Medicine County and Lyon County in September 2016 and additional infestations have subsequently been found in nine more counties including Douglas and Todd County in 2017, Jackson and Redwood County in 2018, Houston and Lincoln County in 2019, Winona County in 2020, and now Polk and Goodhue County in 2021. Although Goodhue County is the eleventh county where Palmer amaranth has been found in Minnesota, none of the infestations that have been identified to date are widespread and it is believed that most of them have been successfully eradicated as the MDA continues its efforts to prevent the spread of this serious weed to new areas and, thankfully and to the MDA’s credit, these efforts have proven to be successful thus far.

Palmer amaranth was designated as a Prohibited/Eradicate Noxious Weed in Minnesota in 2014 and as a Prohibited Weed Seed in 2016. As a result of these regulatory designations, existing plants may not be transported off site and must be destroyed

60

MNLA.BIZ september 21

and absolutely no Palmer amaranth seed is allowed in any seed sold in the state. Because Palmer amaranth is an emerging threat in Minnesota, suspected finds should be immediately reported to the MDA for confirmation and eradication. Suspicious plants should be reported to the MDA’s Arrest the Pest Line at 1-888-545-6684 or arrest.the.pest@state. mn.us (mailto:arrest.the.pest@state.mn.us).

Before the 2018 growing season, all of the infestations of Palmer amaranth that had been found in Minnesota were in conservation plantings rather than crop production fields and were believed to have originated from a single, conservation mix, seed source.

Unfortunately, the more recent finds in Jackson, Redwood, Houston, Lincoln, Polk, and Winona Counties, and this new find in Goodhue County, have been found in agricultural fields — specifically, corn and soybean fields.

In addition, with the exception of the initial infestations that were confirmed in Yellow Medicine, Lyon, Douglas, and Todd County in 2016 and 2017, and the find in Polk County earlier this year where agricultural screenings were the seed source, the sources of the remaining infestations remain unknown.

Several species of amaranth (also called pigweeds) are present in Minnesota and of these species Palmer amaranth is most often confused with tall waterhemp (Amaranthus tuberculatus), a native species that is also a serious agricultural weed. Both species are dioecious (male and female flowers produced on separate plants; individual plants male or female), warm-season annuals that grow very tall (6-8 feet or taller). Having petioles (leaf stalks) that are longer than the leaf blade is a key characteristic that can be used to separate Palmer amaranth from other pigweeds including waterhemp. Palmer amaranth produces copious amounts of seed (a single female Palmer amaranth plant can produce up to 500,000 seeds and the seeds remain viable in the soil for 3 to 5 years), is a fast-growing and highly-competitive weed, and has developed resistance to multiple herbicides with different modes of action including dinitroanilines, triazines, acetolactate synthase (ALS) inhibitors, 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors, and glyphosate-based herbicides. As a result, Palmer amaranth poses a serious threat to agriculture in Minnesota and neighboring states. MNLA members should be aware of this important weed and help prevent its spread via contaminated seed, seed screenings, manure, agricultural equipment,

and other means. It is also important that suspected finds be reported so they can be verified and treated by the MDA as quickly as possible. Since Palmer amaranth is a warm season annual and, given the warm temperatures that we have been experiencing this year, this is a good time to be on the lookout for Palmer amaranth in agricultural fields Ross Recker, University of Wisconsin-Madison, Bugwood.org.

ON JULY 9, 2021, the Minnesota Department of Agriculture (MDA) announced that Palmer amaranth (Amaranthus palmeri) had been confirmed in an agricultural field in Goodhue County in southeastern Minnesota.

Figure 1. Palmer amaranth (Amaranthus palmeri), a member of the Amaranth or Pigweed Family (Amaranthaceae) and native to the southwestern United States and northern Mexico, is a new and potentially serious weed in Minnesota that nursery and landscape professionals should be on the lookout for and report to the Minnesota Department of Agriculture; having petioles that are typically as long or longer than the leaf blade (as shown here) can be a good identifying characteristic for Palmer amaranth compared to other pigweeds (Amaranthus spp.) which have petioles that are typically shorter than the leaf blade.

and other disturbed sites including roadsides, vacant lots, and gardens. Nursery and landscape professionals are encouraged to report suspected finds to the MDA. The MDA news release announcing the discovery of Palmer amaranth in Goodhue County is available on the MDA website at https://www.mda.state.mn.us/minnesota-department-agriculture-confirms-palmer-amaranth-goodhue-county.

Additional information about Palmer amaranth, including how to identify Palmer amaranth and differentiate it from other species of amaranth is available on the MDA website. ➽ IF YOU HAVE QUESTIONS OR COMMENTS regarding this MNLA Regulatory Update or the status of EAB in Minnesota, neighboring states, or North America, contact Jim Calkins, MNLA Regulatory Affairs Manager, at jim@mnla.biz or 952-935-0682.

GILI

GILI is a unique leadership development program custom designed with a Green Industry focus. It is open to a select cohort each year.

The course meets 10 times during the year, one time per month February to December (except May). The curriculum is founded on the power skills (referred to by many as “soft skills”) needed for leaders in today’s workplace, tailored for the MNLA community.

HOW TO CHOOSE A GILI CANDIDATE First of all, let’s define a few terms.

CANDIDATE/STUDENT: The person who attends GILI. SPONSOR: The person responsible for the financial decision to send an employee to the Leadership Institute.

DIRECT MANAGER: The person who gives the most direct oversight to the candidate’s day-to-day job. In some cases, this person may also be the Sponsor.

Choosing a candidate from your company should be done carefully. Here are some tips for selecting the right person.

Sponsors: Meet with key managers of your company and explain the program. Ask managers to nominate someone who they believe has the willingness and readiness to focus on developing their leadership management skills.

Candidate Success Factors: • Candidate is willing to learn about themself and willing to practice and apply new perspectives between classes, even though it may seem uncomfortable at times.

• Candidate must be willing to take extra time over and above attending class and their position will allow for this.

• Candidate is disciplined enough to show up to class each month and arrive on time.

• Candidate is open to engaging with other students, offering up suggestions, and sharing information. Does not have a problem with participating in groups.

• Candidate has a track record of being committed, seen by following through with duties from beginning to end.

Candidates that supervise others (even a small number) are preferred. Please explain why the candidate is qualified to attend if he/she has a position that does not include a supervisory component. Exceptions have been made.

Sponsors and/or Managers: Meet with employee to explain the program and ask the employee these questions: • Do you believe you can handle such a program on top of your workload?

• Are you willing and able to focus on the course load as well as take on a project (a substantial deliverable worked on throughout the GILI year)?

• How can I help to make this a reality for you? (In other words, is there something that has to be modified for their job in order for this person to take the course?)

When Considering Candidates: If the job position is such that the individual must call in last minute unable to attend, please reconsider or redesign the position’s expectation. This course requires consistent attendance. Only one absence is allowed.

MNLA.BIZ september 21

We would like to welcome Louise Nemmers as the newest member of the MNLA staff.

Louise is the new Administrative Assistant for the office, and brings with her over 15 years of experience managing small offices, primarily nonprofits here in the Twin Cities.

She loves the chance to wear many hats and sees herself as the hub of the office. She is always looking for efficiencies and ways to improve the work. As she says, she is good at “bringing order out of chaos.”

Louise has her Master’s in Art History and Museum Studies, and in her spare time you can find her volunteering at a local historical society or art museum. While she enjoys chatting with the guests and visitors, she is

even happier working behind the scenes in the archives or cataloguing items in the collection. Louise also enjoys biking the paths along the Mississippi, reading whatever the book club selection is, and has started Nordic walking as a new excuse to be outdoors.

Louise and her senior adopted mutt Pepper live in the Prospect Park area of Minneapolis, and she finds living on the border between Saint Paul and Minneapolis the perfect spot in the Metro. She has one daughter who lives in Washington D.C., and family across the country that she loves to visit.

We are so pleased to add Louise to our team!
