Inspect your landscape trees and shrubs often- especially after storms. After storms, hazard trees with loosely hanging branches or split trunks need to be removed as soon as possible to avoid any damage to buildings, people, and to other trees or shrubs.
At other times of the year keep a watchful eye for developing decay in trunks and roots, broken and hanging branches, dead branches or trees, an abnormally leaning tree, or anything that may indicate that a tree or part of it could fail and cause damage or injury.
Certified Arborists can offer advice on which plants should be removed, which ones can be saved, and if Plant Health Care (PHC) treatments are necessary. Visit the International Society of Arboriculture (ISA) website to find a Certified Arborist nearest you.
