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.
