Have you seen trees and shrubs on client's properties that exhibit off-colour, stunted growth or dieback? Do clients ask what could cause the decline with some of our woody landscape plants? Have you ever been asked to do a post-mortem exam for you client's trees, and felt overwhelmed by where to even start? Then this is the seminar for you! Jen and Johl have over 50 years of combined experience in the nursery, landscape and arboriculture industries and they love to teach STRATEGIES for detecting, diagnosing and solving plant health issues. CEUs are available.
