[ FROM THE PRESIDENT ]

Monthly Presidential Musings

Tim Gray WSNLA President Pacific Stone Company Everett Water. That’s one singular word that is amongst the most important ‘words’ to human beings and the planet Earth. In so many ways we’re

awash in water, surrounded by it. We’re unhappy when not enough falls from the sky, unhappy when too much of it falls from the sky. Our livelihoods depend on it, as does our very existence and life itself.

Here in the Pacific Northwest we’re blessed, we can see ‘water’ from the snow-capped mountain ranges to the salt waters whose shores we live upon.

I’ve often said the following: I need air. I need food. I need water. Without each of those most essential of needs we couldn’t survive.

4 - The B&B Magazine

I do not know why our portion of the world is changing so drastically, be it global warming or climate change. I won’t say my personal thoughts, because we’re a broad-ranging association of many different beliefs.

What is known is that we’ve been enjoying one of the driest and warmest years in recent memory. It’s been lovely, and certainly very good for our industry.

Like all good things, they can come to an end as there are possible ‘storm clouds’ on the horizon.

The good weather means we don’t have our historic reserves in the mountains, although most water municipalities managed their resources well this past winter. We should be good for a while, and let’s hope we return to a more ‘normal’ weather pattern next winter.

If we don’t our industry will be greatly impacted. Governor Inslee has declared a drought emergency, which sets up potential support of many areas. It also makes it possible that we’ll see restrictions for us and our customers.

Through our WSNLA Lobbyist, Heather Hansen, we’ve got proper representation in Olympia, keeping an eye out for our industry.

At Legislative Day, WSNLA members met with Robert Duff, Senior Policy Advisor for Natural Resources and Environment in the Governor’s office, to discuss

the water issues we may be facing.

WSNLA is working to keep you and our industry on the ‘front lines’ of what may become a battle for the horticultural community. If those ‘storm clouds’ on the horizon don’t come in the form of rain off the Pacific Ocean we’ll be facing potential severe restrictions of water use. If you think it won’t happen here, just look southward to our neighbors in California. Established water rights over a century old are being shut off, and people are living with fairly steep required consumption reductions. Plus skyrocketing water bills.

As an industry we’ve done many good things to manage this valuable resource, even though we live in a historic land of plenty when it comes to water. If or when WSNLA needs your individual voices please be ready to respond.

In the meantime, it’s summer time so get out there and enjoy what living in Washington State is all about. Spending time outside, gathering with family & friends, taking vacations, and of course working too. Summer is my favorite time of the year, no doubt. I love sunshine.

Cheers, Tim Gray

Regulatory Update WSNLA Works To Protect Your Business

Derek Sandison is New WSDA Director Started June 15

WSNLA's Scholarship & Research Charitable Fund

Derek Sandison began his cabinet-level position as director of WSDA on June 15. A senior Ecology manager who has worked extensively with the agriculture community on water access issues, Sandison has been meeting with industry leaders and WSDA staff since Gov. Jay Inslee announced his appointment May 21.

“Our Department of Agriculture helps support a multi-billion industry and works closely with growers, workers, tribes and communities around the state,” Inslee said when the announcement was made.

“Derek has a successful record of leading on incredibly complex and large-scale projects and brings a commitment to innovation, transparency and collaboration that is exactly what we need to maintain and grow Washington’s world-class agriculture industry.”

Most recently, Sandison was director of the Wenatchee-based Office of Columbia River at the Department of Ecology, where he managed water supply projects along the Columbia River Basin. He was also a principal architect of the Yakima River Basin Integrated Water Resource Management Plan and has played a key role in other water supply efforts such as the Odessa Ground Water Replacement Project.

Sandison has also been regional director for the Department of Ecology’s Central Region. Based out of Yakima, this region covers seven counties stretching from the Canadian border to Klickitat and Benton counties.

As WSDA director, Sandison will oversee an agency with a budget of about $158 million and a staff of 750 that can grow by 200 during harvest season. WSDA has a broad range of responsibilities that include protecting plants and livestock from pests and disease, ensuring the movement of agriculture products, managing the use and registration of pesticides, and ensuring the safety of the state’s food supply.

Sandison earned a bachelor’s degree in biological science and a master’s in natural resource management—both from Central Washington University.

Cascade Water Installs Efficient Irrigation Learning Lab at Lake WA Institute of Technology Cascade recently partnered with the Environmental Horticultural program at Lake Washington Institute of Technology (LWIT) in Kirkland to install an irrigation system utilizing some of the best available technology to achieve efficient irrigation, such as weather-based controllers, soil moisture sensors and drip irrigation.

The learning lab will be incorporated into the program to teach students the basics of smart watering techniques as well as irrigation system scheduling and management.

The irrigation hardware was donated by Hunter and Rain Bird, two of the largest irrigation system manufacturers. LWIT students provided the lion’s share of the labor, and Cascade designed the system and oversaw the project. During the installation, students learned the basics of trenching, pipe sizing, cutting, gluing, wiring, valve box construction and sprinkler head installation.

Cascade and school officials are presently planning to develop a draft degree program on sustainable landscaping and irrigation efficiency later this fall.

In addition to the learning and career development opportunities for the Environmental Horticultural students, the agreement between Cascade and LWIT allows Cascade to utilize the irrigation system and facilities at no charge for training landscape and irrigation contractors and other groups, which provides additional value and saves money for Cascade. A video of the project can be viewed at: https://vimeo. com/131227375 “Our students will have a better awareness of the issues related to water and irrigation… they will know the right questions to ask.” – Don Marshall, Program Director. LWIT.

Ed Hume Inducted Into Gold Circle

Honored by National Academy of Television Arts and Sciences, Northwest Chapter.

To achieve your dreams in this professional industry, watch, listen, learn and show respect to others. Then when you get your chance, you should never be afraid to try something new, even if it’s outside your comfort zone.

Gardening personality Ed Hume has been inducted into the ‘Gold Circle’ of the National Academy of Television Arts and Sciences, Northwest Chapter. Hume received the award at the 52nd Annual Northwest Regional Emmy Awards. He is the eighth member of the television industry, in the northwest, to ever receive this most prestigious ‘Emmy award’.

Hume’s plaque reads in part “honoring television’s most prolific gardener to the northwest... and the world. Ed has been pulling weeds and sowing seeds in front of a camera since 1962”.

Ed Hume is a Northwest native, born in Seattle some 83 years ago. He is a Certified Professional Horticulturist, graduating first Master Gardening Class at Washington State University in Seattle in 1971. After serving in the Army, he spent 10 years in managerial positions in the gardening industry before beginning his career in garden communications.

In 1965 his first full-time industry job was as host of GreenUp Time on KIRO, where he also made guest appearances on 8 - The B&B Magazine

JP Patches, the news and other feature programs. It was at this time in his career that he also started writing a gardening column for the Seattle P-I and began a daily program on KIRO radio.

In 1969 he moved his program to KING, changing the name to Gardening with Ed Hume. During his 19 years there he appeared as a regular guest on Seattle Today. He also made guest appearance on the news, Almost Live, The Dick Kinger Show, Evening and many other feature shows. Ed became garden editor of the The Seattle Times and KING radio during this period. And, his show was expanded to the Portland and Spokane markets, where he participated in many local and regional telvision shows.

For 10 years, Ed and his wife Myrna taped Christmas specials titled Deck the Halls. These shows drew upwards of 40,000 pieces of mail. Ed hosted two specials for the late Fran Guidos: The Arboretum Thing and The Olmsted Brothers.

Hume thanked the academy for the distinguished honor of being inducted into the Gold Circle.

He also said ‘it’s been a terrific 50 plus years for us... and, I do mean us, because our entire family has been involved from the beginning.

So the award is to be shared with my wife Myrna and our sons Jeff and James for 50 years of Gardening in America & 10 years of our Christmas show Deck the Halls’.

(Hume’s son James has produced, directed and edited over 4000 segments of the show.)

In 1988, he moved the show to KOMO, first renamed Ed Hume on Gardening, then Gardening in America. In addition to being broadcast on KOMO and its affiliates in Boise, Portland and Spokane, the show was syndicated across the US into approximately 50 million households. For two years the show was broadcast on NHK, Japan’s number one television station, to a viewing audience of 100 million people.

(Ed’s voice was dubbed Japanese.)

Ed’s television program “Gardening in America” celebrates its 50th anniversary this year. Gardening in America is the longest, continuously airing gardening show in America... with Hume as host all 50 years. In fact, it is believed to be the longest continuously on air gardening television show in the world. It also holds the longest regional record, as no other northwest TV program has ever reached 50 years of broadcasting.

Hume is also the author of seven books on gardening and contributed columns to several national gardening and lifestyle publications. He has received numerous accolades and awards throughout his career from a variety of garden-based local and national organizations, including Past President of Washington State Nursery and Landscape Association, WSNLA Educator of the Year, WSNLA Pioneer Award Recipient, and WSNLA’s Harold Young Lifetime Achievement Award.

Ed, who has twice been invited to visit and televise the gardens of the White House, has served on several non profit boards. During his time on World Concern he went to Haiti to advise farmers and staff on farming techniques. He has also supported the Diabetes Association, Northest Kidney Centers and Seattle Chilrdrens’ Hospital.

Ed was instrumental in organizing an educational program for the Monroe Reformatory, which prepared inmates for outside employment once they were released. With Myrna and friends, he formed People Aiding the Homeless, which helped provide funding, food and shelter for the less fortunate. Since the 1980s the Hume family has donated millions of dollars of seed packets to Third World countries, those affected by the 9/11 and Hurricane Katrina tragedies, community projects, foodbanks and other charities.

Gwen K. Stahnke | Walla Walla Community College Nathan E. Stacey & Rita L. Hummel | WSU Puyallup Research and Extension Center Low impact development is an emerging concept for managing urban stormwater. A critical tool in the low impact development approach and one of importance to the green industry is bioretention (Dietz, 2007). Bioretention cells, commonly known as rain gardens, are shallow depressions in the landscape filled with soil media and plants. They can be implemented on various scales from small residential lots to large commercial properties. Rain gardens use the biological, physical, and chemical properties of plants, soil media, and microorganisms to infiltrate water and filter pollutants and are intended to be long-term installations.

Plants are an essential component of rain gardens; they absorb nutrients, transpire water and help maintain favorable soil infiltration and microbiological activity. The moisture status of plants within a rain garden can vary with season and location.

In the Pacific Northwest, plants must tolerate wet winters as well as dry summers, preferably without supplemental irrigation. During wet seasons, rain gardens will have different hydrologic zones, varying from temporarily saturated, oxygendeprived conditions in low areas to dry conditions in upper areas that merge with the existing landscape. For long-term success, identifying plants that will be healthy and viable under these widely varying conditions is crucial.

Most rain garden research has been done in the eastern U.S., which has substantial rainfall in the summer, when evapotranspiration is high. The heavy winter rainfall and summer drought typical of the Northwest provide challenges for survival of rain garden plants, and research is needed to

evaluate the suitability of different plant species for use in different moisture zones within rain gardens. In order to expand the list of plants recommended for rain gardens in the Pacific Northwest, replicated rain garden research to evaluate 30 different plant species and cultivars was initiated in late summer 2010 at the Washington State University Research and Extension Center in Puyallup. In this paper we will report on the growth and survival of the grass species included in our research.

Sixteen research rain gardens were installed as part of a Low Impact Development stormwater research program partly funded by a Washington Department of Ecology grant (www. puyallup.wsu.edu/stormwater/). The rain gardens include 4 replications each of an unplanted control and three different landscape designs: a tree and shrub planting; a mixed landscape planting with trees, shrubs, ornamental grasses, sedges and rushes; and a managed grassland planting of turf-type grasses.

Picture 3 shows the rain gardens in October 2012 and Picture 4 & 5 show June 2015.

Each rain garden cell has approximately 256 sq.ft. of surface area. A bioretention soil mix of 60 percent sand and 40 percent recycled yard-waste compost (by volume) was spread to a depth of 18 inches. The cells have a flat bottom area (approximately 10ft x 10ft) and sloping edges. This creates hydrologic zones of varying soil moisture (the wetter bottom, the dryer top and the sloped zone that transitions between the top and bottom zone).

Managed Grassland. Grasses for the managed grassland were seeded in late summer 2010. Each rain garden was

The four quadrants are: tall fescue, a coarsertextured species typically regarded as more droughttolerant because of its deep fibrous root system; fine fescues (chewings and creeping red), fine textured species considered low-maintenance due to their slow growth; colonial bentgrass, a fine-textured stoloniferous species adapted to the Puget Sound area; and a fine fescue/colonial bentgrass mixture. Seed was manually watered as needed to insure germination.

Ornamental Grasses. Ornamental grasses for the rain gardens were selected based on aesthetic characteristics and their considered potential for survival in the different rain garden hydrozones. The species, container size at transplant, and number of individuals included in the rain gardens as-well-as the hydrologic zone (dryer on the top, wetter in the bottom and transitional on the slopes) where they were planted are listed in Table 1 on page 12. Ornamental grasses were obtained from local nurseries, selected for uniformity and transplanted to the rain gardens in fall 2010. Plants were mulched to a depth of 3.5 to 4 inches with arborists’ wood chips.

All plants were manually irrigated at planting in the fall of 2010 and then relied on natural rainfall until the summer of 2011. Drainage of the rain gardens in this study was excellent and no standing water was observed during the winter months. An overhead sprinkler irrigation system was installed, and from June to September 2011 all rain gardens were irrigated as needed to prevent plant water stress. After September 2011, no supplemental irrigation was applied to the (From Top to Bottom) Pictures 1 & 2 shows rain gardens the first growing season when plants were small and all plants were exposed to full sun.

rain gardens. Table 2 shows the precipitation during the

time of this experiment measured by a WSU AgWeatherNet station (http://weather.wsu.edu/awn.php) located about one-half mile from the rain gardens.

Once established, the managed grassland rain gardens were treated as minimally mowed turf. Maintenance typically consisted of cutting all grasses back to a height of 3 inches two or three times during the growing season. Maintenance of the ornamental grasses was limited to cutting all grasses back in late winter.

Data on survival, growth, and quality of rain garden plants is being collected. A grant from the WSDA Nursery License Surcharge Fund was awarded in fiscal year 2013 to help fund plant data collection. Ornamental grass survival data from spring 2011, spring 2013 and spring 2015 are presented in Table 1. When considering plant growth and survival results it is important to consider how the environment in the rain gardens has changed over time as plants have grown. Figure

2 shows rain gardens the first growing season when plants were small and all plants were exposed to full sun. Figure 3 shows mixed landscape rain gardens after 2 growing seasons (fall 2012) and Figure 5 shows rain gardens in June 2015. In rain gardens with trees and shrubs,

many of the ornamental grasses that were in full sun are now in dense shade.

Figure 6. Percent of cover in the managed grassland rain gardens measured in spring 2015 using digital image analysis.

Each rain garden was divided into quadrants and quadrants were seeded with the turf grasses indicated. Data represents the average of four replications.

Results of visual evaluations the spring following transplant (Spring 2011) indicated survival was 100% for all 4 ornamental grass species. In the summer of 2012, August and September were extremely dry with no rainfall and 0.01 inches, respectively (Table 2), and some plants exhibited water stress symptoms.

Figure 3 shows the ornamental grasses on October 11, 2012, the pictures were taken the day before it started to rain. All ‘Boulder Blue’ oat grass and ‘Little Kitten’ miscanthus were alive and growing in spring 2013 and only 1 of the 8 ‘Skyracer’ moor grass plants in both the transition and wet rain garden zones was dead (88% survival rate). Survival was much lower for ‘Northern Lights’, a variegated tufted hairgrass cultivar with only 17% survival of plants in the transition zone. This cultivar is considered “one of the few ornamental grasses that grows well in shade” (Missouri Botanical Garden) and it did not do well in the full sun environment characteristic of the rain gardens when they were first planted.

cover of the turf-forming grasses in the managed grassland rain gardens was determined in June of 2015 using digital image analysis (Richardson et. al., 2001). To reduce variation, all plots were photographed on one individual morning when light conditions were similar. Images were then analyzed using software that accounts for variation in green tissue. The results are shown in Figure 6. Due to space constraints, not all quadrants collected the same amount of sunlight. Therefore, trends must be carefully interpreted. The data does suggest that certain turfgrass types are more vigorous than others, under these particular conditions.

Table 1. Survival of ornamental grasses under evaluation in the WSU Puyallup LID research rain gardens. Plants were placed in different hydrozones in the rain gardens based on their potential adaptation. All plants were transplanted from containers in fall 2010 and irrigated as needed with overhead sprinkler irrigation during the summer of 2011. Plants were not irrigated after the summer of 2011.

Results after four growing seasons indicate all turf and ornamental grasses except the ‘Northern Lights’ deschampsia grew well in the WSU Puyallup rain gardens. As the trees and shrubs continue to grow, shade will increase and this competition for light will likely influence growth and survival of those grasses that require full sun.

EPA “Waters” Rule Published

By Craig Regelbrugge, AmericanHort

The U.S. Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers have pressed ahead and published their final Waters of the United States rule, rebranded as the Clean Water rule. While EPA and the White House have finetuned and sharpened their messaging, early review of the 300-page rule suggests few changes to the substance. As previously reported by AmericanHort, the rule could subject numerous marginal waters to federal regulation and create confusion and liability for land and business owners. We will provide more detailed analysis after careful review.

Clean Water Rule: Definition of “Waters of the US”

- Pre publication copy of the rule issued on May 27 - The rule will become effective 60 days after it is published in the Federal Register

Why Does the Rule Matter?

Reaction to the release of the final rule, which takes effect 60 days after posting in the Federal Register, was swift and negative. Rep. Collin Peterson (D-MN), the highest ranking Democrat on the House Agriculture Committee, said the following in his official statement:

1. Many additional waters, including roadside, irrigation and storm water ditches, farm ponds and man-altered and man-made water bodies could be subject to Clean Water Act (CWA) Regulations under the proposed rule

“I am disappointed but not surprised that the EPA has decided to move forward with a rule that would increase confusion and red tape. Farmers, ranchers, local communities and businesses all expressed concern with the negative impacts of this rule. Despite that, EPA either wasn’t willing to listen or simply just does not get it.

2. Expanding the number and scope of waters subject to CWA regulation, also subjects those waters to key CWA requirements such as:

“I am committed to working with my colleagues on both sides of the aisle to explore all available options to ensure these arbitrary and subjective regulations never go into effect.”

- CWA Section 404 Wetlands permitting - NPDES permitting - Total Maximum Daily Loads (TMDLs) - Numeric Nutrient Criteria

On May 12, the House passed legislation (H.R. 1732) to require the agencies to withdraw the rule and work with stakeholders to develop a new rule. The Senate Environment and Public Works Committee held a hearing on similar legislation (S. 1140) on May 19. The Senate Small Business and Judiciary Committees are also planning hearings on the regulation. However, even if Congress were to pass legislation to overcome the rule, it may well face a White House veto.

3. The Clean Water Act provides for citizen action lawsuits that can compel EPA or the Corps to take regulatory action

Horticultural Research Institute: Pollinator Research Underway

The Horticultural Research Institute, in collaboration with AmericanHort, established the Horticultural Industry Bee & Pollinator Stewardship Initiative in 2014.

One of the primary goals of the Initiative is to identify and fund research that will help answer key science questions and fill gaps needed to inform, design, and refine an industry stewardship program.

The Initiative’s focus on research is a key component in establishing a clearer understanding of horticulture’s impact on pollinators.

One researcher who received project funding this year is Dr. Richard Cowles, Connecticut Agricultural Experiment Station (Windsor, CT). Dr. Cowles is analyzing pesticide residue in pollen and nectar on neonicotinoid-treated plants. Using plants commonly used in the landscape, Cowles expects to further develop an understanding of systemic insecticide update and potential interactions with nectar and pollen. Why is this important?

Currently, there are significant gaps in data related to the concentration of systemic insecticides. Establishing whether treated plants (when treated properly) are safe to bees and other pollinators will aid in setting stewardship standards for growers and assist in educating retail sellers and consumers about the practices of growers.

16 - The B&B Magazine

To date, Cowles has embarked upon dose-response tests on minute pirate bugs, using neonicotinoid insecticides and their suggested replacements. An early goal for the project is to establish whether the pirate bugs can be utilized in the bioassays (ie: can the team quantify the insecticide residues in the pirate bugs). His team is further investigating the active ingredients, application methods, and application timing relative to flowering as factors that may influence the residues found in nectar and pollen of ornamental plants.

A second project underway is led by Dr. Daniel Potter of the University of Kentucky (Lexington, KY). Dr. Potter and his team are working to identify best management practices by which producers and landscape managers can protect plants from pests while simultaneously mitigating risks to bees.

His research also has the potential to

support planting recommendations for landscapes that sustain bees throughout the growing season, identify plants that warrant particular caution when using systemic insecticides, and highlight plants whose floral characteristics reduce the potential for bees to be impacted by systemic insecticides. Potter’s team has already implemented work to assess the extent and longevity of translocation of soil-applied imidacloprid and dinotefuran into nectar and pollen. Flowers from early-blooming species in the project were collected, bagged, and transported to a lab where anthers with pollen were removed from each flower by forceps. Flowers were spun in centrifuges to remove nectar. Samples are stored until all three plant species in the project have been sampled. From the lab, they will travel to be analyzed in a blind review for insecticide residues.

Potter’s team has also begun work to document bee assemblages (types of bees, bee species richness and diversity) associated with numerous species of flowering woody ornamentals, and to rate/ rank those plants in terms of attractiveness to bees. To achieve this, bees are being sampled from approximately 40 species of common flowering trees and shrubs across multiple sites. Bees are netted, preserved, coiffed in a fan-driven bee drier, pinned, labeled, and identified. Comparisons are being made between native and non-native plants, trees versus shrubs, and plants having particular sets of floral characteristics.

This is one of the most extensive pollinator surveys ever done on woody plants and, when completed, will form the basis for science-based recommendations for beefriendly landscape plants.

IN REMEMBRANCE Cherie J Bouley, (October 11, 1950 -

May 4, 2015), is survived by her partner Richard Crerie, who misses her terribly and her sister Charlotte Bouley. Cherie retired from Blooming Nursery in the fall of 2012 when she was diagnosed with brain cancer. Her previous employments included Etera and Color Spot. Her passions were books – biographies and history mostly fiction; music of all genre – she could have opened a store with her collection; nature- she loved to hike; gardening – she loved her garden and had a thing for growing peppers – sweet and hot. Cherie, who always had a smile on her face at industry events, will be dearly missed by friends and family. Her laugh and her sense of humor will be missed. Details on a memorial service will be shared when available.

My Garden Nursery Opened April 1 at New Location in Bellingham. While their location has

changed, co-owners, Jenny Gunderson and Bill Raynolds will continue to offer exceptional customer relations by delivering top-notch service and in-store experiences.

For example, their fun, colorful, and exciting full-service nursery will include a ping-pong table. If anyone can beat Raynolds in a game, they’ll win a plant, but don’t get your hopes up – Raynolds lost only once to a customer when they operated My Garden Nursery for seven years in Mill Creek.

Other family oriented activities include a train table for young children, a Fairy Festival and a Birthday Club where customers get a discount equivalent to their age for shopping on their birthday. My Garden Nursery also will be active in the community by raising funds for Alzheimer’s and breast cancer research.

“I love that the community loved Bakerview Nursery and that so many are happy there will be a nursery here again,” Gunderson said. To learn more about My Garden Nursery visit www.mygardennursery.com.

Lenora Groesbeck Walters, (March 9, 1919 - May 26, 2015). Although she suffered from polio as a young girl, she had an active childhood; biking around town and the surrounding area and swimming in the Columbia River.

After graduation in 1938, she attended WSC in Pullman, majoring in speech.

It was at WSC that she met the love of her life, Stanley Walters. Moving to Puyallup in 1942, she and Stan began their involvement with the community, volunteering in many capacities, from PTA to church activities. They established and operated a nursery/bulb farm there until their retirement in the late 70s.

Lenora assisted Stan with the nursery while raising their three children, Linda, Mary, and David. She was Secretary/ Treasurer for the WA State Nursery Association for 10 years and wrote a column for the American Association of Nurserymen for many years. She and Stan hosted several Japanese Agricultural Students, received an Honorary Life Membership in WSNA and in 2000, they were the recipients of that organization’s Pioneer Award. A creative artist and eager learner, she was a long time member of the local Arts and Crafts organization and the Naomi Ch. # 13 of Eastern Star. She belonged to the garden club and several study groups, and as an “empty nester,” she completed her book of poetry, Sunlight and Shadows in 1980. In their retirement, Stan and Lenora traveled extensively in Asia and Australia. They never tired of making new friends, often not hearing English spoken by others for weeks. In addition to traveling, they completed the construction of their summer home in Goose Prairie, WA and were proud to be able to create the Walters Family Scholarship through the WSNLA Scholarship & Research Charitable Fund. Lenora will be remembered by all as a warm and caring individual, always eager to learn, and most willing to share her creative abilities whenever she could. She will be greatly missed by all who had the honor and privilege of knowing her.

Certified Professional Horticulturist ”Being a CPH adds credibility to the work you do”

Steve Herbig, CPH

Horticulturist | Metro Parks Tacoma

Q. How long have you been a CPH? Herbig: 10 years, 28 if you count 18 years as a WCN. Q. What is your job title/company name?

Herbig: Horticulturalist/Metro Parks Tacoma Q. What services/products do you provide?

Herbig: I mainly work in the gardens (annual, perennial and shrub beds and 8 specialty gardens: Dahlia trial; Fuchsia, Herb, Iris, Japanese, Native, Rhododendron and Rose) at Point Defiance Park and also along Ruston Way doing full scale grounds maintenance, design and installations.

Q. What does it mean to you to be a Certified Professional Horticulturist?

Herbig: For me, being a CPH is both a personal and professional goal that I have wanted to accomplish. The work and effort I have put in has paid off and I feel successful in my chosen field of employment that at times can be frustrating however always rewarding and enjoyable. Being a CPH adds credibility to the work you do.

Q. What is your overall philosophy for being successful in the horticulture field?

Herbig: Determine what aspect(s) of horticulture you are most passionate about— what really intrigues you and then work to learn all that you can about it. As you do this, you will build a strong foundation which you can then add to and expand upon as you gain knowledge and experience and you will see how different aspects of horticulture tie into each other.

Q. What is the biggest challenge you face in your job?

Herbig: Lack of Time. There just never seems to be enough hours to accomplish all of the work tasks that need to be done with many of the tasks competing against each other to be done at the same time. All of my work happens in a public place, now factor in events like wind or ice storms, vandalism, animals (deer, raccoons, etc.),

18 - The B&B Magazine

equipment and utility failures, labor shifts/shortages, special projects, all take away from that finite amount of time available each day which makes it hard to keep up with everything let alone to get it done at the most appropriate time.

Q. What is an example of a recent success story for your business?

Herbig: In February we started the second phase of a planned renovation in one of the sections of the rose garden in Point Defiance Park. We were expecting to have everything go the same way with this one as we did with the first one we did two years before however this time we had a lot of rain which turned the site into a muddy mess and slowed the project down. The project included lifting, storing and replanting approximately 200 roses, removal of old soil and installation of new, a drainage system and irrigation upgrade. We were able to finish the project and are already seeing positive benefits from the work done. This project also had some benefits outside of the garden---we discovered and repaired a failing drain line, upgraded a catch basin and repaired a waterline.

Q. How has your certification and/or WSNLA helped you professionally?

Herbig: By challenging me in working towards certification, obtaining and then maintaining my certification through continuing education requirements; allowing me to meet industry professionals, and to see different aspects of the horticulture industry which helped me to build my horticulture foundation.

Q. How do you use your certification to promote your business/services?

Herbig: Recently I shared with a new manager my certification, they were intrigued and wanted to know more about the CPH program. I also have over the years shared my thoughts with management that having at least a basic understanding of horticulture would be very beneficial to park (grounds) maintenance workers in that whether you are caring for turf, trees, shrubs, flowers---all of them make a park a park.

Q. What is your most trusted ‘go to’ resource for horticulture questions?

Herbig: For me, my ‘go to resource’ includes all---I have been building a small library of books, articles, papers over the years; I have a number of websites that I use and I consult with friends and coworkers and I occasionally will do some tests/trials to see what works best. I find that by doing this, I continue to build and strength my horticultural foundation---there is always something to learn about to help you do your job.
