Practical Use of Plant Growth Regulators in the Plant Nursery

Room B116

Speaker: Dr. Jozsef Racsko, Technology Manager, Mycorrhizal Applications LLC.
In this technical seminar, attendees will learn about the commercial applicability of plant growth regulator (PGR) products; when and how to apply them, what rates to use, what factors influence their efficacy (weather conditions, water pH, plant health status), and how these products can be integrated into the production practices. The presentation will review results from commercial trials and research experiments and provide guidance to the audience on how to interpret such research information. This will help growers find the right solution tailored to their turf or ornamental crop and growing conditions. The presenter will discuss how growing protocols can be adjusted to specific conditions to take full advantage of PGR products.

Extreme Weather: How it Affects Crop Production With Solutions Offered

Room B116

Speakers: Lloyd Nackley, Professor, Oregon State University and Dr. Drew Zwart, Plant Pathologist / Physiologist, Bartlett Tree Research Laboratories
Extreme weather events are more common than ever. For example, in 2021 the north Willamette Valley had catastrophic ice storms in late winter. The winter melted into a warm spring and exceptionally hot summer that was exemplified by the 113 F “heat dome” in late June. While the average annual temperatures in our region will only increase by a few degrees each decade, these extreme (greater than 10 F above average) hot and low-temperature events have devastating and long-lasting effects on nursery producers. Learn about how climate change and extreme weather are affecting nursery production, and what growers can do about it.

Cultivating Cultivars Seed to Tree: The 30-Year Timeline for Climate Resistant Urban Trees

Room B116

Speaker: Nancy Buley, Communications Director, J. Frank Schmidt & Son Co.
It’s a long and complex journey from seed to city tree. Many hands and a decade or more are needed to grow a tree from start to finish. It takes even longer to develop, select, trial, and introduce new and improved cultivars. Bringing new and improved urban tree cultivars to market is a multi-generational effort that may take 15–30 years or more, via the collaborative efforts of plant breeders, growers, urban foresters, arboreta, and academia. Understanding the timeline and processes of new tree introduction and the how and why of cultivar development will help you plan ahead for choosing, growing, and planting the best trees for the future urban forest.

Soil Moisture: Top Factor for the Survival of Newly Installed Plants

Room B110

Speaker: Wei Zhang, Vice President of Research and Development, TreeDiaper
Urban trees tend to struggle because it is not an ideal growing condition between pavements and buildings. Underwatering and overwatering are the most common causes. Water prescriptions are developed to address this problem, but too much of the water is wasted. The most important factor for tree survival is the soil moisture, not how much water is dumped onto the root ball. New methods of increasing plant available water and stabilizing soil moisture will be discussed.

Measuring for Change—the Lean Way

Room B116

Speakers: Rick Peters, President, The Peters Company | Elizabeth Peters, Vice President, The Peters Company
“In God we trust. All others must bring data.” This quote by W. Edwards Deming refers to the significance of data measurement in doing business. Why? Because measurements drive behavior; what you measure is what you get. How do we choose what to measure? Which metrics give us the best prospect of achieving our goals? How can we use data to manage and motivate labor effectively — and how do we use all this information to improve our business? This seminar looks at measures for different levels of a company. It also offers an approach to implementing metrics and common pitfalls to avoid.

Solving Plant Problems Virtually

Room B110

Speaker: George Grant, GGSPro Technical Specialist, Griffin Greenhouse Supplies
Whether a grower is working internally with their cultivation team or externally with cooperative extension personnel, product vendor representatives or technical specialists often rely on some form of virtual communication (e.g., cellphones, emails, or video conferences). We are all familiar with the saying, “a picture is worth a thousand words,” but knowing what picture to take and what information to gather before reaching out for consultation is important in diagnosing an issue correctly and efficiently. The objective of this presentation will be to build a checklist growers can use for gathering valuable information once they have identified an issue in their production setting.

Stressed Out: How to Diagnose, Treat, and Avoid Environmental Stress in Landscape Plants

Room B116

Speaker: Linda Chalker-Scott, Ph.D, Professor and Extension Specialist in Urban Horticulture, Washington State University

This seminar will present a diagnostic approach to discovering the cause behind landscape failure. Many landscape plants fail to thrive, or even die, because of avoidable errors in selecting, transplanting, and maintaining trees and shrubs. Without understanding the underlying reason behind landscape failure, homeowners and professionals often resort to pesticides and fertilizers in an unsuccessful attempt to fix the problem. An alternative set of suggested best practices will be presented based on recent and on-going research, which ultimately will help landscape managers avoid the unnecessary use of chemicals.

Keynote Address – Katie Tamony

C123-124

Speaker: Katie Tamony , Chief Marketing Officer, Monrovia Nursery Company and Former Editor-in-Chief of Sunset Magazine and Sunset Books FREE to all registered Farwest Participants. Many of us have spent years in our industry, and it’s easy to forget what it’s like not to know what we know. It’s also natural to fall into habits of seeing problems and patterns a certain way. But holding a “beginner’s mindset” can help us solve problems more effectively, adapt to change more easily, and actually create more original ideas. So how do we change our perspective and see things with fresh eyes? Looking at the familiar in an unfamiliar way can help us be better leaders and refresh our teams and our approach to our business. Using examples from throughout a career where she has been forced to be a “beginner” operating at a high level, she will share some techniques and ways of leading and innovating with fresh perspective.

FREE to all registered Farwest Participants.

Above- & Under-ground Partners: What Urban Trees are Missing

Room B119

Speaker: Wei Zhang, Ph.D., Vice President of Research and Development, Zynnovation LLC

Trees in the forests live with their family and friends. Above the ground, young trees are protected by mature trees against extreme weather conditions such as scorching sunlight, damaging wind, and extreme cold. Equally, and maybe more important than the above ground partners, the underground partners; insects, worms, and root and soil microbiome, is critical for the survival and thrive of the baby trees. How can we expect turban trees to survive and thrive with compacted soils, excess stormwater runoff, salt, pollution, insecticides, herbicides, fungicides and more.

Flathead Borers in Nursery and Orchards

Room B113

Speaker: Melissa Scherr, Ph.D., Research Associate, Nursery Crops, Oregon State University Extension

Flathead borers can be serious pests of nursery trees and tree nut and fruit crops in the Pacific Northwest. In particular, two flathead borers in the genus Chrysobothris — C. femorata (flatheaded apple tree borer) and C. mali (Pacific flatheaded borer) — contribute damage in many different deciduous trees and shrubs grown commercially, weakening or even killing trees by girdling the trunk or branches. A third species, C. nixa, attacks cedar and juniper nursery trees. The flatheaded apple tree borer is a common pest in the Eastern and Central United States, while the Pacific flatheaded borer and flatheaded cedar borer are only found west of the Rockies. The Pacific Northwest region is home to all three species.
