Caring for our Senior Trees Workshop – Houston

April 19 @ 9:00 am - 4:00 pm


This ISA Texas Chapter Master’s Series will help you understand how trees age and teach the specialized skills required to maintain mature trees.  Mature trees respond differently to available resources and environmental changes than younger trees. Tree health care management must account for the unique processes of mature trees and different arboricultural practices are required to help maintain mature tree health, structural integrity, and growth.   Mature tree physiology and prescriptions for pruning, fertilization, and prevention of injury will be highlighted.
