Title: Trees Have Hormones and They Know How To Use Them!

Summary: Hormones help different tree “parts” communicate. This presentation will focus on how the environment triggers changes in tree physiology and ultimately tree anatomy. Clients tend to only think about the tree’s anatomy, so it is up to the arborist to help the client develop objectives, predict the tree’s response, explain limitations, and evangelize our mantra - right tree, right place. How do trees use their hormones in response to such basic arboricultural practices as pruning and fertilizing? The goal of this presentation is to re-examine what we thought we knew about hormones and to learn the latest of how tree hormones mediate the tree’s interactions with its environment.
