Tim Gray WSNLA President Pacific Stone Company Everett Many of my earliest memories are of trees. Seattle’s Emerson Elementary had the classic ‘Horse Chestnut’ on the playground. Who needs anything else when there are spiked seed pods lying all over the ground to throw with or at your friends? Our first grade class took a walk to see a “living fossil” in the neighborhood, a Ginkgo tree. My parents took us camping and nursery shopping. On camping trips we explored the woods, often ‘collecting’ seedlings of native trees to plant at home. At nurseries they allowed us to help select their purchases. It could be said that while I wanted to help with this, my brothers Bill and Tom fought it on the same level as trips to the dentist or barber.

I’d venture a guess that most anyone reading the B&B Magazine has the 4 - The B&B Magazine

ability to walk down the street and name the trees under which they walk.

Many people not in the horticultural community have no clue; all trees are gathered into two main groups. Maple trees and pine trees.

Obviously our world wouldn’t exist without trees, and the destruction of forest lands across the globe is something to fear. Still, many times trees have to come down, for all kinds of valid reasons. Disease, construction, or public safety are only a few of the reasons. WSNLA’s work with various public utilities and their Tree Certificates is amazing, and a WinWin-Win-Win situation. Power lines are cleared of potentially hazardous trees. Homeowners get to pick their new trees from a list of quality options.

Nurseries exchange certificates for these trees, and often sell a whole lot more to the homeowner. WSNLA gets a small administration fee for handling the financial transactions, which helps support our programs throughout the year.

In Snohomish and Island counties only WSNLA members are allowed to supply Snohomish PUD’s tree certificates. For

any retail nursery this program alone could pay your yearly dues many times over.

Recently the WSNLA Northwest Chapter held our summer meeting at Jim & Annie Barborinas’ Urban Forest Nursery in Mount Vernon. What a wonderful setting they have to work each day, with offices sitting high above the surrounding acreage filled with so many beautiful trees.

Walking the fields after dinner, heading into sunset, everything glowed with the vigor of new growth, new varieties, and the hope of future generations with young trees that will be growing the next century or two. We’ll all be long gone, but our work of today will be growing strong. Now I just need to figure out where there’s room for one more tree, maybe two, at home on Camano. My child-like fascination kicked in with two of their tree varieties. One, Japanese Hornbeam, carpinus japonica looked like it was full of hops! The other, Hot Wings tartarian maple, acer tataricum ‘GarAnn’ PP 15023 was covered in stunning red seed clusters that looked on fire in the dazzling setting sun. Amazing!

There’s only one question left to ask you: Have you hugged a tree today?

Cheers, Tim

Legislative & Regulatory WSNLA Works To Protect Your Business

Heather Hansen WSNLA Lobbyist Olympia

The legislature finally passed an operating budget, averting an unprecedented government shutdown.

The $38.2 billion budget funds state government operations for the next two years. The budget agreement fully funds state employee contracts, granting them their first general wage increase in seven years.

Here are a few things you may not have read in the newspaper.

The Senate passed an operating budget during the regular legislative session – over sixty days ago. The House did not vote on any budget proposal until the third special session.

The Senate proposal included everything required by law including addressing the McCleary decision by increasing funding for schools and funding mental health requirements.

The Senate budget and the final

compromise included a first time ever tuition cut at state universities. Under the compromise, there will be a 15% reduction in tuition at the University of Washington and Washington State University, a 20% reduction at Western, Central and Eastern Washington universities and The Evergreen State College, and a 5% reduction at community and technical colleges.

The cuts will be phased in, with a 5% reduction this fall for all colleges and universities. In 2016, tuition will be cut an additional 10% at the UW and WSU, and 15% at WWU, CWU, EWU and Evergreen. Tuition at Washington’s public colleges and universities remains far above the national average.

The agreement adds $1.3 billion to K-12 education, including money to reduce class sizes in grades K-3 and expand fullday kindergarten.

The final budget does not include cap and trade, a carbon tax or a new capital gains tax. Governor Inslee agreed to a provision that will prevent him from imposing a low-carbon fuel standard by executive order. It is expected that an initiative creating a cap and trade system will be on the ballot in November.

The transportation package includes an 11.9-cent gas tax increase that will be phased in over two years. The gas tax will increase in two stages: a 7-cent increase on Aug. 1 and a 4.9-cent increase on July 1, 2016. The plan spends $8.8 billion on state and local road projects and $1.4 billion on maintenance and preservation.

Another $1 billion will be spent on nonhighway projects, such as bike paths, pedestrian walkways and transit.

On the policy side, fewer bills than usual passed this session, but to many, that may be a good thing.

A few highlights relating to nursery and landscape businesses: ESB 5510 requires the Department of Labor and Industries to convene a working group by August 1 to focus on improving the accuracy, simplicity, fairness, and consistency of calculating and providing wage replacement benefits to injured workers. The working group must report to the Legislature

by February 1, 2016, and September 1, 2016.

SSB 5322 allows conservation districts’ to increase rates. For counties with populations between 480,000 and 1.5 million the maximum per-parcel rate cannot exceed $10. For counties with populations of over 1.5 million – only King at this time – the maximum per parcel rate is raised from $10 to $15.

SB 6057 dealt with a wide variety of small tax issues including defining honey bee products and services as agricultural products. Apiarists who produce honey bee products for sale at wholesale will be eligible for the same sales and B&O tax incentives as other farmers.

The definition of Agricultural product for tax purposes specifically excludes marijuana. The terms “agriculture,” “farming,” “horticulture,” “horticultural,” and “horticultural product” may not be construed to include or relate to marijuana.

The special sessions were not limited to budget issues. During the second special session, the new Director of Agriculture, Derek Sandison, was confirmed by the Senate. Sandison’s background is in water rights. He comes with high regards from all who have worked with him in the past.

[ FROM THE EXECUTIVE DIRECTOR ]

WSNLA’s community creates an industry canopy that delivers protection, promotion, and collaborative education.

Breanne Chavez WSNLA Executive Director WSNLA, a trade organization, is very much like a tree. It is an organization founded and funded by businesses that operate in a specific industry: horticulture. Using the illustration below, consider this concept the roots and tree stock that creates our foundation.

As a tree grows, branches are formed. This also occurs within an industry trade association as they begin to participate in activities that work to strengthen the industry. Specifically, WSNLA delivers industry public relations and advertising, education, political advocacy, and publishing. The branches grow at different paces and shapes as activities expand, adapt and contract.

However, the main focus of WSNLA, as any industry trade association, is collaboration between companies, working to create a standard. The illustration represents this idea well with hands in various sizes, shapes and colors facing different directions. Much like WSNLA’s community, these hands represent our more than 250 diverse nursery and landscape business members, nearly 100 horticulture individual members, and more than 400 certified professionals with varying interests, concerns, viewpoints, talents and skills working to better an industry.

WSNLA’s community creates an industry canopy that delivers protection, promotion, and collaborative education. On behalf of the Washington horticulture industry, thank you for your membership and contribution.

(TOP) The primary focus of Chrishaven Trees is the production and sale of B&B trees, 1.5’ caliper and larger. 36” rootballs are picture here. (Bottom) JOSE CAN BE SEEN DIGGING WITH THE HOLMAC.

Chrishaven Trees is a family business specializing in the production of shade and flowering trees for the wholesale trade. The family has been involved in the agricultural industry in Skagit Valley for four generations. Sue and Ken started the nursery in 1990 and welcomed their son Jay to the business in 2012.

The primary focus of Chrishaven Trees is the production and sale of B&B trees, 1.5’ caliper and larger. In addition, one acre is devoted to Pot-in-Pot production of #15, #20, and #25 gallon containers. A limited number of trees are also planted to growbags each year to provide another option for summer digging.

Trees are harvested with a Holmac digger which allows for relatively close row spacing of 6’ centers with break roads every 15 rows. Various size liner plants are sourced each year and, depending on size, are either transplanted directly to the field or

A major priority is placed on sustaining the nursery by the most ecologically sound means possible.

Sue Christianson, CPH, co owner of chrishaven trees, stands beside a pot in pot tree. (below) Chrishaven Tree employees care for their potted liners.

are potted and grown on for one year to produce a more desirable size plant and vigorous root system. Preference is given to spring transplanting. Fields are amended for acceptable pH and are deep tilled prior to planting.

Transplants are supplemented with a light application of Nutri-Rich organic poultry fertilizer and a transplant solution composed of an organic transplant supplement, Terra-Sorb hydrogel and mycorrhizae. New plantings are staked and sprinkle irrigated to ensure strong plant establishment in the critical first year of growth.

A major priority is placed on sustaining the nursery by the most ecologically sound means possible. All fields have been deep-tiled which provides excellent sub-surface drainage in the winter months, resulting in healthier soil environments and stronger root systems. Annual cover crops are seeded in the fall to minimize winter soil compaction and run-off. Incorporation of cover crops in the spring add to soil organic matter, improving soil structure and enhancing mechanical weed control. Thankfully, the nursery has been maintained free of undesirable noxious weeds such as nutsedge, quack grass, and sand rush.

As may be expected, the majority of B&B tree harvest commences in the dormant season from late October through mid-April. However, Pot-in-Pot production and a limited number of grow-bag raised plants are available year-round. To supplement summer harvest demand, Chrishaven Trees has perfected a summer harvest protocol which has been amazingly successful on most species in the nursery. Prior to summer digging, trees are root drenched with a solution of up to 25 gallons of BioPlex Organics Transplant Concentrate 48-72 hours prior to harvest. Digging is scheduled for the early morning hours followed by a liberal application of a wilt-proof product applied to foliage. As soon as the foliage has dried, plants are placed under a fine overhead mist for 3-5 days depending on species. Good judgment must be used

on avoiding some of the more sensitive species and on avoiding periods of extreme heat. With experience, this system has been quite successful.

With over 65 differing cultivars in production, it is interesting to address the unique culture of various species to meet customer demand. Not all customers are looking for the same form in a given plant type. With such a diverse customer base and plant mix, Chrishaven Trees strives to provide some variety in available plant forms. All pruning and plant culture is done in a way to reflect the unique Chrishaven brand quality. For instance, some specimens are grown in various forms such as multi-stem, low branched, or tree standard. Although most customers seem to prefer plants with a single leader, not all plants are naturally disposed to this form and this must be taken into consideration. At the end of the day, the customer is right and the Chrishaven goal is to deliver a plant of good health and superb quality.

Visitors are welcome at the nursery by appointment or visit their web site at www.chrishaventrees.com.

Training Young Trees

promote preventative structural pruning

ISA CERTIFIED ARBORIST HORTICULTURE INSTRUCTOR, EDMONDS COMMUNITY COLLEGE & CONSULTING HORTICULTURIST

Multiple codominant branches wit included bark. Photo: B.Bronstein.

Following a structural pruning program during the first 15-25 years of a tree’s life is the best way to promote development of a tree with good structure. So, what are the basics of structural pruning? As with most ornamental pruning, remove dead, dying, diseased and damaged branches first. Then follow the strategies below.

by B. Bronstein them to become healthy attractive trees as well the center of the canopy. as structurally sound trees that are less prone to breakage or failure in the future. Nursery and landscape professionals can and should promote preventative structural pruning of young trees to deal with this issue.

Young ornamental trees that are planted and left unpruned for a number of years often develop structural defects that are not only aesthetically displeasing and potentially unhealthy for the tree, but can also increase risk to people and property. Common structural defects are codominant stems (stems that are of similar diameter size, grow at similar rates, and originate from the same point on the tree), included bark (bark pinched between two stems), and unbalanced canopy (one side of the canopy is significantly heavier than the other, or most of the canopy weight is at the branch tips).

12 - The B&B Magazine

• Remove and/or shorten competing stems. You may use a combination of removal (thinning) and reduction pruning cuts to accomplish this. You may need to repeat pruning on vigorous competing stems and branches.

The illustration on the next page provides more information on how to achieve this.

2. Identify the lowest scaffold branch in the permanent canopy

• Identification of the lowest permanent scaffold branch aids in identification and management of temporary branches.

• Branches on newly planted trees are often all temporary branches, but are needed as they help young trees with establishment and development of trunk taper.

3. Prevent temporary branches from growing too large

Bad structure is seen in a tree with multiple leaders, codominant stems crowded together, and a top-heavy canopy (Photo on right). Good structure is seen in a tree with one dominant leader, branches spaced evenly along the trunk to promote a balanced canopy, and an absence of defects such as codominant branches and bark inclusion (Above Illustration) Reducing the stems represented by the dotted lines shortens two of the three codominant branches in this young tree. (Bottom illustrations) A reduction cut reduces the length of a stem or branch to an existing lateral stem or branch that is large enough (generally at least one-third the diameter of the cut stem) to take over apical dominance. A removal (or thinning) cut removes a stem or branch back to the trunk or parent branch, to just outside the branch collar.

A

• Reduction cuts are used to subordinate or slow the growth of temporary branches, in order to keep them smaller and less vigorous than permanent branches.

• Ultimately all temporary branches will need to be removed for clearance as the tree matures, but smaller branches mean smaller pruning wounds.

4. Space scaffold branches evenly along the trunk

• Choose well-spaced scaffold branches (1-3 feet apart, depending on species) both vertically up the trunk as well as rotationally around the trunk.

5. Keep all branches less than half the trunk diameter

• A branch protection zone is present at the base of a branch that is less than half the diameter of the larger branch or trunk where it is attached. This tissue inhibits spread of decay organisms into the branch collar when a smaller branch is pruned off.

• Reduction cuts can be made on vigorous permanent branches to subordinate or slow down growth and keep the branches less than half the diameter of the trunk.

6. Suppress growth on branches with included bark

• Remove a defective branch with included bark when possible. However, if you are not able to immediately remove branches with included bark, reduce the branch to slow down its growth and remove excess weight that could lead to breakage.

A good structure can be developed in a tree with five to seven scheduled pruning sessions over the course of a tree’s first 15-25 years after planting. How often you prune (pruning cycle) and how much is pruned off (pruning dose) will depend on a number of variables: the tree species, the quality of the nursery tree, growth rate, climate, and even the landscape management budget.

A B Regardless of these variables, all young trees require pruning after planting, and good structural pruning will insure a stronger, longer lived tree to be enjoyed by all.

Growing Washington’s Urban Forests One Landscape, One Community at a Time

Ben Thompson Urban Forestry Specialist

Wa State Department of Natural Resources

The Washington State Department of Natural Resources (DNR) is best known for its work in the wildlands, however, the agency also provides assistance to Washington cities and towns to help them manage their own natural resources.

energy through shading and buffering of winds, and sequestration of carbon from the atmosphere. Ecosystem services improve the health and quality of urbanized environments and result in cost-savings to communities that properly care for their urban forest.

The wetlands, natural areas, city parks, tree-lined streets, and other vegetated landscapes in your community are all natural resources, and together they comprise an ecologically functioning system that we call an urban forest.

Urban forests provide many benefits in the form of what is known as “ecosystem services”, including: interception and filtration of stormwater, purification of the air, attenuation of noise, conservation of

Communities’ natural resources are public assets, as they are components of infrastructure. We invest in infrastructure because it provides essential services and benefits, and we maintain infrastructure to ensure it persists; thus the urban forest is equally deserving of the attention and care we devote to our buildings, streets, and utilities.

Recognizing this, the DNR’s Urban &

Community Forestry Program provides technical, financial and educational assistance to cities and towns in Washington. The goal is to help communities create self-sustaining municipal forestry programs that manage trees for public benefits and quality of life. However, we are a small program and rely on support from statewide partners like WSNLA to help us further our mission.

Perhaps the most visible work of DNR’s Urban & Community Forestry program is the administration of Tree City USA in Washington State. Tree City USA is an award program run by the Arbor Day Foundation at the national level, however, like other state forestry agencies, DNR administers Tree City USA at the state level. There are currently 86 Tree City USA Communities in Washington and nearly 50% of Washingtonians live in a Tree City USA community.

Tree City USA is an inclusive program, designed so that any incorporated city or town has an opportunity to participate regardless of their population, location, climate, staffing, or finances.

The Tree City award can be earned by meeting four requirements that symbolize a community’s commitment to managing the urban forest: 1.) designate a staff person or establish a volunteer tree committee to offer guidance for tree management issues; 2.) enact a municipal tree ordinance; 3.) track their annual tree-related activities and costs; and 4.) celebrate Arbor Day every year.

A community with attractive parks, tree-lined streets, and verdant natural areas is one that will attract others who feel similarly about the health and quality of their own properties. Private property owners will dictate the future of Washington’s urban forests, as most of the land within city boundaries is privately owned.

DNR’s Urban & Community Forestry Program is not authorized to provide direct assistance to private property owners, however, we actively promote the importance of purchasing high-quality nursery stock, installing well-designed landscapes, exercising industry best practices, and hiring credentialed professionals.

In return, we hope that our partners like WSNLA are encouraging local communities to properly manage their urban forests and join the ranks of other Washington cities earning the Tree City USA designation.

As our state’s population continues to grow, and as our city boundaries continue to expand, the need for healthy urban landscapes and the ecosystem services they provide will only increase. And together, DNR’s Urban & Community Forestry Program, along with WSNLA and many other allied partners, will be there to help ensure that Washington continues to earn its reputation as “The Evergreen State.”

Thank you WSNLA members for all of your hard work and continued support.

Lints Serves on Behalf of the Industry Q&A with KIRSTEN LINTS, CPH GARDENS ALIVE DESIGN & URBAN & COMMUNITY FORESTRY COUNCIL MEMBER How did you become involved on the council? My recommendation was made

by WSNLA on April 14, 2014 to serve and fill the WSNLA seat on the council. Peter Goldmark, the Comissioner of Public Lands, approved the appointment on May 22.

The first meeting that I attended was in Gresham, Oregon on June 6, 2014 which was a joint meeting with WA State Urban & Community Forestry Council and Oregon Community Trees. Since then we have had meetings at the Spokane & Yakima Arboretums, the WA State Capitol as well as other venues.

The term expires December 2016 and meetings occur 4 times/year.

With a desire to positively represent the WSNLA to the Urban Community Forestry Council, learn more about urban tree projects, benefits and uses, advocate for Tree City USA & return information about urban tree issues to the WSNLA community, it has been my pleasure to serve in this capacity.

Serving with representatives from universities, community colleges, WA DOT, Parks & Rec, arborists, tribal lands, WSU extension, DNR & Community Development Directors the conversations has been thought provoking because of the various vantage points and progressive in small steps with this complex issue. A huge thanks to Linda Vane, King County Dept. of Natural Resources working with Firewise Communities, for the initially recommending my involvement with the Urban Forestry Council.

What do you value most from your participation on the council?

Albeit a steep learning curve for the first few meetings, urban forestry research and promotion have been fascinating. The undervalued urban tree will require continual protection & education to help residents understand the importance in our communities. It is true that we all love our urban trees until the mature maple is where we’d like to place that outdoor shed or swing set then sadly the tree is removed with little understanding to the impacts on the larger urban environment.

One very important step to increase the value of Urban Trees would be to assist your community in becoming a Tree City USA. Not only a badge of honor for your community, many studies have proved the increase in property value with the addition of urban trees and many, many other benefits to residents. Contact me if you are interested in learning more about Tree City USA or find more information here; http://www.dnr.wa.gov/about/boards-andcouncils/washington-community-forestry-council .

REMINDER: Earlier this year, Seattle updated their street tree ordinance, which calls for the registration of all firms that provide tree pruning or removal for hire. In addition, it

is also required that all pruning or removal work be supervised by an ISA Certified Arborist (not necessarily on site at all times, but supervised, nonetheless). To register please visit the Tree Service Provider registration form online at: www.seattle.gov/ transportation/docs/stuse/Tree%20 Service%20Form.pdf Firms wishing to register, can return the completed form to seattle.trees@ seattle.gov along with other required material.

City of Seattle’s Street Tree Manual (info on Tree Service registration is on page 24) is also available online at: www.seattle.gov/transportation/ docs/Street%20Tree%20Manual%20 WEB.pdf If you have questions regarding Seattle’s street trees and/or ordinances, please contact City Arborist Nolan Rundquist (Seattle Department of Transportation) seattle.trees@seattle.gov

City of Tacoma: Growing Tree Canopy Cover to 30% by 2030. In 2001, a U.S. Forest Service data noted Tacoma’s tree coverage at 12.9 percent. In an effort to improve this percentage, the City of Tacoma created EverGreen Tacoma to manage, protect and expand Tacoma’s tree canopy cover. In 2010, the City Council adopted a new chapter in Tacoma’s Comprehensive Plan - the Urban Forestry Policy Element (UFP). This chapter houses the vision for Tacoma to enhance urban forest resources, including increasing the tree canopy cover from approximately 19 percent in 2009 to 30 percent in 2030.

As in any other city, Tacoma has area and land that can grow more trees and there are parts that can grow less due to development. In order to break the city-wide goal down into more manageable goals, further analysis was completed. Using the data from above and Tacoma’s existing zoning and current land uses, we’ve devised the following goals for canopy cover by land use.

Land Use Commercial/Mixed-Use Downtown Developed Park Major Institution Multi-Family Residential Manufacturing/Industrial Parks Natural Areas Single Family Residential Right-of-way/non-parceled areas

Support Washington Community Tree Recovery

On July 14, 2014, lightning sparked in four spots in Okanogan County, Washington. These lighting strikes produced four separate wildfires that, once merged together, produced the Carlton Complex Fire—the largest recorded fire in Washington’s history. The Carlton Complex Fire burned 256,108 acres and caused an estimated $98 million in damage. It destroyed over 300 homes and wreaked havoc on the area’s beautiful tree canopy.

Certified Professional Horticulturist creating & sustaining a culture of professionalism

Susan Hanley, CPH

Chair, South Seattle Community College Technical Advisory Committee, Landscape Horticulture program

I recently attended WSNLA’s Certified Professional Horticulturist reception held at South Seattle College. Considering the location of the event, I found I was waxing a bit nostalgic, recalling when I was a student at South’s Landscape Horticulture program years ago. While taking classes in plant identification, pruning and horticultural science, I really couldn’t see much past my pruning shears. It was an exciting time of learning and anticipating putting that horticultural knowledge to good use.

As luck would have it, my instructor Steve Nord referred me to Rod Bailey, then President of Evergreen Services Corporation. As they say, the rest is history as I spent the next fifteen years in his employ.

My first impression of the company was ecstatically positive as I walked into the operations office to accidentally interrupt a manager as he was feeding a squirrel. Looking about the room I also noticed a pegboard with different 18 - The B&B Magazine

cones, identification tags and a number of framed “W.C.L” certificates hanging on the wall. (For those readers younger than the bicycle I ride, W.C.L. was WSNLA’s initial C.P.H. designation. It stood for Washington Certified Landscaper and it had a ‘twin’ certification for nursery professionals, the Washington Certified Nurseryman.) The squirrel and the cone identification board? Yeah, they were cool. But the certificates really drew my attention and curiosity. I soon came to understand what this W.C.L. business was all about.

I learned that this particular company had a culture, a culture of professionalism. People who worked on maintenance crews were expected to have their Commercial Pesticide License (yes, including the Insect & Disease Control designation). The company provided the study materials and paid for the tests, encouraging individuals to do their best and solicit help if needed. What really got me

excited was the opportunity to go for my W.C.L. I recall my instructor at South Seattle Community College encouraging those of us soon to graduate that we should definitely go for this as our plant identification skills were still fresh in our minds. That, he said, was the most difficult part of the exams.

I gave it a shot and was successful, asking my boss to sign a letter noting my employment information. I was to officially receive my certificate after one year of working in the industry.

Word got out in the company that the new kid working in the Seattle Division got her W.C.L. Congratulatory gifts started rolling in, a copy of the “Sunset Western Garden Book” along with a new pair of pruners and sheath AND a company tee shirt. What mattered most was that I was noticed. I had joined a club of professionals who had proven their knowledge in the field of horticulture. I remembered how great that was and how proud I was to hang

that W.C.L. certificate on the wall over my desk as I took on a position of greater responsibility. A year later, I returned to my boss, asking him to sign a letter stating that I had worked a year in the industry. Surprised at how swiftly time flies, he gladly signed the letter and noted that “Well, I guess you’re due for a raise.” Bingo! Eventually, I was chosen to head up a new human resources department, something that I never would have imagined as a hort student at South Seattle Community College.

What the heck, I thought; this industry will always be powered by people, lots of them.

In 2001, I was fortunate to join a cadre of professionals as a principle and Human Resource Director at Signature Landscape Services, Inc. I was happy to continue that culture of professionalism at my new company, instilling pride in those who took the challenge to become certified.

Having an opportunity to influence new employees and recruits was empowering.

When I hired students or graduates from programs and people with experience in the industry, I would always say, “Okay, now you’re in the company, let’s talk about what type of certification you want to go after.” As the industry grew, so did the opportunity to acquire multiple certifications, C.P.H., C.L.T. (now known as

Landscape Industry Certified Technician or Manager), I.S.A. and the new ecoPRO designation.

For those with a solid understanding of horticulture and a strong knowledge of plants, I would challenge those recruits to take the Certified Professional Horticulturist exam. I relished the idea of seeing a cohort recognized for their knowledge, knowing that a little bit of their pride would rub off on their colleagues, burnishing that professional culture even more. Some would say that letters behind your name are only as important as all the other letters in the alphabet, really not much. I would suggest to the naysayer to ask anyone with industry certification what that means to them on a personal and professional level. Ask the owner of a company how having staff that is certified helps in promoting professionalism. And, ask a client if they would prefer hiring someone with proven industry knowledge or a nice looking truck. I have a guess what those responses would be.
