New Challenges Everyday

Lucinda McMahan, CPH WSNLA President Lucinda’s Landscapes | Mountlake Terrace As I write, I find myself in the thick of a very busy season. No surprise to anyone reading this. New challenges everyday.

Our Association has its unique challenges everyday, as well. One that comes to mind is the ongoing challenge to communicate the various WSNLA member benefits and activites to members and potential members. The Certified Professional Horticulturist and ecoPRO Certified Sustainable Landscape certification programs have similar challenges.

The ecoPRO Steering Committee is in place to guide program outreach and marketing. However, recently a Certified Professional Horticulturist marketing sub-committee has been formed to address what can be done to elevate the industry and consumer awareness and understanding of the Certified Professional Horticulturist designation. And, to get a broader message out about professional certification.

To help with this effort, a survey was developed and emailed to all Certified Professional Horticulturists in July. If you are a Certified Professional Horticulturist, please take a few minutes to complete the survey.

You will receive various email notifications before the deadline of August 31.

I worked really hard for my certification to distinguish myself as professional with professional credentials.

I know many of you feel the same. If you are a CPH or ecoPRO, I am interested in hearing what your certification means to you. Please share your thoughts with me at lucinda31@comcast.net.

Thank you, Lucinda

[ FROM THE EXECUTIVE DIRECTOR ] As a ready partner, WSU is asking for our voice and input.

Breanne Chavez WSNLA Executive Director Last month I had the pleasure of meeting the new WSU Dean of College of Agriculture, Human & Natural Resource Science Dr. André-Denis Girard Wright, an internationally recognized researcher and director, at a luncheon that included industry and community stakeholders. Dr. Wright shared his professional background and experience with us that included work in Canada, Australia and Arizona. His excitement peaked when giving focus to his experience building programs through partnerships and across industries.

He thoughtfully listened to each stakeholder’s comments on industry challenges and needs.

Why is this important to you? Because Washington State University is a land grant university, and, per Wikipedia, “A land-grant university (also called land-grant college or land-grant institution) is an institution of higher education in the United States designated by a state to receive the benefits of the Morrill Acts of 1862 and 1890.

The Morrill Acts funded educational institutions by granting federally controlled land to the states for them to sell, to raise funds, to establish and endow “land-grant” colleges.

The mission of these institutions as set forth in the 1862 Act is to focus on the teaching of practical agriculture, science, military science and engineering (though “without excluding... classical studies”), as a response to the industrial revolution and changing social class.”

Our industry is an important sector of the Washington agriculture community. Over the last several years, we have lost many WSU research and extension professionals serving our industry to retirement. To date, those positions have not been filled. WSU horticulture programs are struggling with low enrollment – a trend seen across the country. As an industry, we have not given clear voice to the research and education needs that will support advancing horticulture businesses into the future.

At a time WSU is looking forward strategically, they have engaged industry partners, including WSNLA, to be a part of the conversation and planning. The time is now for our industry to speak up with clear and concise needs. If we don’t, there is a chance WSU entomologists, soil scientists, plant pathologists and other specialists will not understand the various and unique intricacies horticulture professionals come across in their business of growing plants, caring for plants and land management.

You may remember that earlier this year WSNLA hosted a Grower Research Summit that set priorities for research. The results of this meeting provide a good foundation, but more information and direction is needed across the industry. Please watch for a survey being sent out in September to all members. This is your opportunity to provide input on issues pertaining to pest and disease, sustainable practices, innovative technologies, water and other research and education needs. The data collected will be shared with WSU and will directly impact the future of their service and relevancy to our industry.

I look forward to hearing your input, as your Association communicates industry needs in support of a stronger relationship between the Washington horticulture industry and Washington State University.

Good News and Bad about Washington State’s finances When the Washington State Economist released the June revenue forecast, it added nearly $600 million to taxes expected to be collected through the 2019-2021 biennium.

Washington’s economy is expanding rapidly. Income, employment, and population growth all exceed national averages. Of course, growth is not happening equally across the state.

There is more good news on the revenue front. Tax revenue may increase even more due to a recent U.S. Supreme Court decision. The court decision grants the authority to require online retailers to collect sales taxes from online sales regardless of whether or not the business has physical presence in the state. It is anticipated that Washington may collect hundreds of millions of dollars a year in extra tax revenue. This also levels the playing field for those who maintain brick and mortar stores and have in state employees.

Despite all this good news from a state budget perspective, demand for more money in the budget is expected to increase even greater than revenue growth.

That problem will be exacerbated by another recent U.S. Supreme Court decision that requires Washington State to replace all culverts that have been deemed to impede fish passage. The ruling forces the state to pay 100 percent of the cost of replacing the culverts under state highways. It does not address culverts owned by the federal government or city and county governments. Washington Department of Transportation estimated it would cost $3.7 billion to fully comply with the 9th Circuit ruling. The ruling covers more than 900 culverts in Western Washington. A group of 21 Western Washington tribes filed the lawsuit.

While we are on the subject of taxes, the House of Representatives created a Tax Structure Work Group to facilitate public discussions throughout the state regarding Washington’s tax structure. Their goal is to collect information on the advantages and disadvantages of the state’s current tax structure and potential options to improve the current structure for the benefit of individuals, families, and businesses in Washington state.

Who believes in young and beginning producers? We do.

Many companies say they support up-and-coming talent. We’ve created an entire loan program precisely for this purpose. AgVision offers less restrictive loan underwriting standards, mentors and educational resources to give young and beginning producers a fighting chance to grow and compete in a challenging industry.

It’s one more way we’re helping agriculture thrive.

ARE NATIVE TREES AND SHRUBS BETTER CHOICES FOR WILDLIFE IN HOME LANDSCAPES? HOME GARDEN SERIES

Dr. Linda Chalker-Scott, Associate Professor and Extension Specialist, Department of Horticulture, Washington State University 10 - The B&B Magazine

FS300E

WSU EXTENSION | ARE NATIVE TREES AND SHRUBS BETTER CHOICES FOR WILDLIFE IN HOME LANDSCAPES?

Overview Many gardeners prefer to use native plants in their landscapes. Part of this preference is the widespread belief that native species are better ecological choices, especially in providing habitat for native wildlife.

Most published research demonstrates that the native status of trees and shrubs has little influence on biodiversity. This publication provides a more practical, science-based approach that will enhance both wildlife biodiversity and the aesthetic appeal of home landscapes.

Introduction Gardeners increasingly seek out native plant species for their gardens and landscapes. Many believe that native plants are better choices because they are adapted to local conditions.

The U.S. Environmental Protection Agency (EPA), among other federal, state, and local agencies, perpetuates this belief by making many unscientific statements about native plant benefits. Among these claims are that native plants are superior to introduced species in their ability to withstand local climate conditions, to resist pests and disease, and to require less water, fertilizer, and other forms of maintenance (EPA 2017). None of these claims have been supported in published research relevant to home gardens and landscapes.

In addition to their preference for native plants, gardeners also welcome beneficial, native wildlife species who serve as pollinators and natural pest controls in the landscape. They believe that native plants provide the greatest benefits to native wildlife, as the populations coevolved with one another. While there is certainly some evidence to support this belief, especially with specialist insects who require a particular food source, the popular belief extends far beyond the documented evidence.

It stands to reason that trees and shrubs with the greatest chance to survive and thrive will provide the greatest benefits to associated native wildlife. Therefore, we need to consider the realities of typical home landscapes and their impacts on plant survival. How closely do urban and suburban areas mirror the environmental conditions that native plants require? For instance, consider these facts about home landscapes:

Figure 1. Urban soils are frequently unprotected, compacted, and eroded, making survival difficult for many native woody species.

Figure 2. Drought stress is commonly seen in urban trees and shrubs that don’t receive supplemental irrigation in the summer.

FS300E | PAGE 2 | PUBS.WSU.EDU Washington State Nursery & Landscape Association - 11

WSU EXTENSION | ARE NATIVE TREES AND SHRUBS BETTER CHOICES FOR WILDLIFE IN HOME LANDSCAPES?

• • • • • •

Soils often consist of abrupt layers of “topsoil” and other materials, creating poor drainage and low oxygen levels.

There is significant soil compaction as a result of foot and vehicular traffic and the lack of protective mulches (Figure 1).

Leaching of lime from concrete can increase soil pH, which may exceed the pH tolerances of native plants.

Improper fertilizer application can result in nutrient imbalances.

Lack of adequate water in summer months can harm species adapted to a forest environment (Figure 2).

Hardscape surfaces reflect both heat and light that can affect survival of trees. and shrubs adapted to cooler, shadier environments.

It is clear that urban and suburban environmental conditions are unlikely to resemble whatever existed prior to development. This means that many native woody species will not thrive in an urban or suburban landscape (Figure 3). With these environmental realities in mind, let’s consider a research question: does the use of nonnative woody species reduce the food and shelter available to beneficial wildlife?

Scientific Analysis In 2015, I published an analysis of the scientific literature which provides the content for this publication (Chalker-Scott 2015). (Readers can access this original article for more information.) Specifically, I wanted to discover whether woody plant nativeness would influence animal biodiversity. I focused on trees and shrubs planted in urban or suburban landscapes. I found over 120 articles from 30 different countries that studied the biodiversity of birds, insects, mammals, and reptiles.

My literature analysis revealed that, with few exceptions, the native status of trees and shrubs had no impact on wildlife biodiversity.

Researchers identified woody plant structure, function, and diversity as the most important characteristics for enhancing wildlife biodiversity. Native woody species can be part of this scenario but may not be a major component. The ability of native trees and shrubs to live in our home landscapes is determined by the environment—not by their genetics.

Figure 3. Arbutus menziesii, the Pacific madrone, thrives in rocky environments and is ill suited for urban soils.

Gardeners should realize that wildlife will adapt to new food and habitat sources as they become available.

WSU EXTENSION | ARE NATIVE TREES AND SHRUBS BETTER CHOICES FOR WILDLIFE IN HOME LANDSCAPES?

The fact that many exotic, invasive plant species are spread by birds, who ingest and release the seeds, demonstrates that resource adaptation occurs. The same phenomenon occurs with most wildlife, with the exception of those with very specific resource requirements.

Site Conditions and Plant Choices As you think about your landscaping choices, consider these research-based suggestions.

•

•

• •

Site considerations should always dictate plant selection. Determine the potential environmental stresses your trees and shrubs may experience.

Native, temperate forest trees and shrubs generally do well in larger landscapes with neutral-to-acidic, well-drained soils.

Instead of using space-loving larger trees in smaller sites, use smaller trees or shrubs that can be arborized (Figure 4).

If your landscape soils are alkaline, poorly drained or otherwise dissimilar to native soils, choose woody species adapted to those conditions regardless of their nativity.

• •

For sites with higher levels of reflected sunlight or heat, choose woody species adapted to hot, dry climates.

Determine the food and nesting habitat needed for your wildlife species of interest.

Figure 4. This arborized rhododendron provides a tree-like function in a limited space landscape.

Action Items for Gardeners Gardeners can enhance wildlife diversity in their home landscapes in a number of science-supported ways: • • • • • • •

Reduce open lawn and replace it with vertically diverse vegetation (Figure 5). Keep lawns where they serve a purpose, such as play space for children or pets.

Remove known invasive woody species and replace with comparable native or noninvasive species. Be sure to do this during the appropriate season, when invasives are not being used for nesting and foraging.

Increase shrub and tree cover, especially if your landscape is distant from forested areas.

Wildlife will seek out protected vertical spaces for food and shelter.

Check state and national invasive species list before purchasing plants. While plants may not yet appear on your state’s list, the national list will show you where they are currently a problem.

Select site-tolerant trees and shrubs to increase plant diversity and aesthetics.

Plant fruit-bearing trees and shrubs, for consumption by you and your wildlife (Figure 6). Be cautious with such plantings in areas of commercial orchard crop production, due to the potential for pest and disease management issues.

Enhance landscape edges by leaving them alone! Don’t mow or apply any pesticides to these biologically rich environments.

• • • •

Retain dead trees (“snags”), stumps, logs, and piles of branches whenever possible. They provide critical habitat for certain beneficial birds and insects (Figure 7). If snags or other woody debris pose a hazard to people or property, they should be removed.

Protect soils with coarse, woody mulch, especially where compaction occurs. The combination of woody mulches and protected soils improves habitat for insects, reptiles and small mammals (Figure 8).

Eliminate the unnecessary use of pesticides. Utilize good Integrated Pest Management (IPM) practices where pesticides are a last resort.

Add a permanent water feature, when feasible, taking into account potential management issues (such as mosquito breeding). Don’t force your garden wildlife to hunt elsewhere for this critical necessity (Figure 9).

Washington Lean Consortium Reports Significant Improvements Lean is a proven method for eliminating waste.

It results in more value to customers, delivered at a lower cost, in a shorter time, with fewer defects and less human effort.

Members of the Washington Nursery Lean Consortium reported significant improvements when they met for final reports at Skagit Farmers Supply in Burlington, Washington last Thursday.

Leaders from Botanical Designs, Skagit Farmers Supply Agronomy Division, Skagit Horticulture, and T&L Nursery have worked together for one year to apply Lean principles in each others’ organizations.

Reports from the year showed gains that exceeded expectations: · 67% productivity increase on a sedum trimming process at Skagit Horticulture, with 75 percent reduction in people travel. · 408% productivity gain for racking plants for installation jobs with Botanical Designs. The company cut lead time 81 percent, reduced people travel 75 percent, and eliminated $4,500 worth of unneeded inventory. · Reduced setup time by 67 percent at Skagit Horticulture’s Riverbend site, with a 26 percent shorter lead time and 23 percent smaller crew size for transplanting product.

This team had an overall productivity gain of 25 percent on the process. · Cut 5.25 seconds per plant at T & L Nursery in the process of pulling, cleaning, labeling and moving product to shipping racks.

· 98% shorter lead time for truck loading at Botanical Designs’ Holiday Warehouse. By developing standard work, the process now deploys less than half the number of people and virtually eliminates errors. · Improved productivity 129 percent on a trimming process at T&L Nursery, reducing lead time by 58 percent. · 43% fewer process steps for managing inventory at Skagit Farmers Supply Agronomy North facility, with less paperwork, fewer errors, and better communication between departments.

“The Washington Lean Consortium quickly became a tight group,” said Corey Hill, Operations Manager for Skagit Horticulture. “Inspiration came from cooperation between the companies.

When you host your customers, suppliers— and even competition—it locks you into thinking Lean and holds you accountable.

It’s awesome to be a part of their improvements, too.”

Lean is a proven method for eliminating waste. It results in more value to customers, delivered at a lower cost, in a shorter time, with fewer defects and less human effort. Deployed effectively, Lean not only reduces waste, but brings a strong message of long-term commitment to employee development and continuous improvement.

“Lean has been an incredible tool for us to evaluate and improve our effectiveness,” said Natasha Blanchette, Botanical Designs Production Manager.

CASE STUDY: Lean’s Impact in the Plant Yard The Washington Lean Consortium came together to improve productivity and flow in the plant yard of Botanical Designs, an innovative commercial landscaping company that provides high-impact interior and exterior business landscapes and professional plant maintenance for customers in Seattle and the greater King County area.

Botanical Designs’ plant yard is composed of plant and tool storage for current landscape projects. The company had moved into this space about three years ago, and had to set up shop immediately. The plant yard had fallen into dysfunction, and therefore people working in the area had a difficult time finding what was needed for the job. When the processes were looked at from a Lean perspective, several opportunities to remove waste were uncovered. For example, two crewmembers took 39 minutes--and walked 434 feet--to select plants for a single rack to take to a job site. There were also several tripping hazards and other safety issues across the yard.

The company wanted to reassess the area for organization and functional use. Specifically, they focused on the racking process (from delivery vehicle to installation crew loading), yard layout (empty racks, plants pending for installation, and emergency plant inventory), and hardgoods/tool organization. In the past they had job positions that focused on the organization and upkeep of the plant yard, but currently did not have anyone in this position. The company wanted to determine 18 - The B&B Magazine

whether or not it was necessary to hire someone, or if a process could be developed to keep the area in order without additional staff.

The Process of Improvement

The Botanical Designs team began by systematically documenting the current state of the process – videotaping, measuring distance people were walking, and timing processes.

Members of the Washington Lean Consortium then came to the site to perform “5S,” a Lean method for organizing the workplace.

5S is an important tool for removing excess materials and/or tools from the workplace and organizing the required items so they are easy to find, use and maintain. 5-S helps create a selfsustaining culture, which promotes a neat, clean, efficient, and safe workplace.

“The Lean 5S event was much more than a “clean-up” project, which we have done numerous times without lasting result,” said Helen Farrington, Botanical Designs Exteriors and Holiday General Manager. “Taking the time beforehand to analyze the current methods was invaluable. We suddenly saw not only the obvious internal issues, but also how the interaction of other departments and even vendors delivering product could benefit with

some simple changes.”

The improvement team started by removing unnecessary items from the area. This is the first “S,” called “Sort.”

Crewmembers assisted the team in eliminating more than two truckloads of items, including non-sellable plants, tools, and hardgoods. The Botanical Designs team was receptive to encouragements to let go of items that were obsolete or not in good working condition, allowing the area to be free of barriers and distractions.

The team swept pavement, removed remaining trash, and used a backpack blower to clean up the plant yard.

Having the area clean and clear of unneeded items allowed the team to envision and lay out the flow of different processes in the area. This is the second and third “S” -- “Set in Order” and “Shine.”

One critical process performed in the area is selecting plants for landscaping jobs. The team put racks in order, which allowed designers to select appropriate material quickly and sequentially to fill racks for transportation to the job site.

They would spend much less time searching for needed product.

Temporary visual controls were put in place to see if the new process flow reduced waste and saved time for

Rick and Elizabeth Peters, The Peters Company, will present Basics of Lean: The Power of Continuous Flow at WSNLA’s Day of Professionalism on November 6 in Woodinville. With experience working with a variety of horticulture businesses, The Peters Company, will deliver concepts and takeaways to help you improve your growing operation, garden center, and landscape or supplier business.

those responsible for plant selection.

Value to Botanical Designs

As team members trialed the process in the new layout, they found that one person could select a shipping rack’s worth of material in less than seven minutes—increasing productivity (units per worker hour) from 71 to 361.

Consortium members were energized to discover the new process improved productivity 408%. With this type of gain, one person could do the work of five people.

- People travel 47 percent less to find what they need.

- Lead time for racking reduced 81 percent - Elimination of all un-installable flats - 408 percent increase in productivity (units per worker hour) on the racking process - Engaged and motivated workforce

The results of the one-day improvement event are significant:

Critical Follow Up for Sustaining the Gains

“The amount accomplished in one day was astounding, and could not have been directed by one person to get that type of result,” said Farrington. “The teams were focused and collaborated with each other. We now have a punchlist of longer-term goals, and are staying on track, testing the new methods and tweaking as needed. Team members are accountable to one another, and we actively look for new places to improve.”

As the team was preparing to leave, members of the crew working in the area expressed their thanks to members of the consortium for helping to make their jobs easier and improving the work environment in the plant yard. Having this new flow and standard work was a big encouragement and motivator for those who deliver value to the customer every day.

The Washington Lean Consortium is a group of companies that come together to apply Lean principles to their businesses. This year, four businesses participated in the consortium: Skagit Horticulture, T&L Nursery, Botanical Designs, and Skagit Farmers Supply.

If you are interested in participating, please contact Elizabeth Peters, 503250-2235 or epeters@petersco.net for information and an application form.

The fourth and fifth S-es are “Standardize” and “Sustain.” This involves setting up – and following -- a consistent process and soft accountability for performing 5S audits and safety inspections to keep the area in order. Visual controls are an important part of maintaining organization and minimizing opportunities for clutter.

If you are looking for efficiencies at your business and an opportunity to cultivate staff and team building and innovative thinking, you should consider attending this session on November 6.

Basics of Lean: The Power of Continuous Flow

Presented by Rick & Elizabeth Peters, The Peters Company Continuous flow is a powerful Lean principle that can transform how you do business. Flow helps companies achieve consistently higher operational results by removing barriers that hinder the movement of product or information through process steps. It is an effective way to shorten lead times to customer delivery. This interactive workshop offers immediate, tangible steps to improve your businesses tomorrow!

A fun, hands-on simulation will clearly demonstrate why continuous flow is superior to traditional batch processing — and that no company can truly be lean without flow.
