Certified Arborist Sean Tait with Leaf on the Wind Arboriculture is Back to Teach About Pruning and the Science of Trees!

We are pleased to present this two-part pruning class as well as 2 free evening lectures led by Certified Arborist Sean Tait.



2-Part Pruning Class



Lecture, March 13: The "Pruning 101" lecture will discuss pruning basics, from theory to technique, for the homeowner. Students will learn about basic tree physiology, how to recognize and fix structural problems through pruning, and the limitations of pruning. Class will focus on ornamental tree pruning.


Hands-On, March 16: Saturday's pruning practice will give students practical experience in making pruning cuts and putting the information covered in the Pruning 101 lecture to use. Sean will also go over some aesthetic and ornamental pruning tips to take your trees and shrubs to the next level!

The Effect of Climate Change on Trees in Yakima



The Effects of Climate Change on Trees in Yakima is intended to bring together the recorded data on how the climate in Yakima has changed so far with the effects this has had on the trees growing in Yakima.


Based on local meteorological data from the NOAA weather station at the Yakima airport, and extensive hands-on field work throughout the county working on thousands of trees on hundreds of properties, the presentation concludes with recommendations for homeowners on how to mitigate the damage caused by climate change, and things that homeowners can do to minimize or even reverse climate change itself.



The Intelligence of Trees



What does it mean to be sentient? Are humans the only species that can "feel"? 


Certified Arborist Sean Tait takes guests on a special trip through current research from around the globe to help us better understand how complex our planet's trees and plants really are. From chemical and audible communication, to being picky about who they choose to mate with, you will see trees and other plants in a whole new light!


This lecture is FREE in honor of our state's Arbor Day, but please be sure to register below so we can prepare for your attendance!
