Continue to water your deciduous and evergreen trees! 🌳 🌲
Fall Watering for Trees
While the above-ground parts of deciduous trees go dormant into the fall, the root systems remain active until the ground freezes and requires moisture for continued growth. Prolonged dry periods, especially when late summer and fall temperatures are high, can result in root damage, stunted growth, early defoliation, branch and tip dieback, and even overall death of sensitive trees and shrubs.
Water when air temperatures are above 40 degrees and there is no snow cover on the ground.
