How to Manage Pests

Pests in Gardens and Landscapes

Wind injury

Strong, persistent wind can cause the bark to split or crack and scaffolds to break. If a strong, dry wind persists during the growth period of the foliage, the leaves in the most exposed areas develop small, dark lesions between the veins, twisting and folding the growing leaf. Many of these leaves drop.

Solutions

Insect pests and disease can render a tree susceptible to wind damage, weakening scaffolds or rotting the structural wood. Proper pruning and training of young trees and controlling insects and disease will help prevent wind damage. Consider wind breaks or planting several trees together to lessen problems in very windy areas.
