Birch Tree Pruning: Avoid Spring, Prune in Fall Dormancy

Prune birch trees only if necessary. Spring pruning causes heavy sap flow, attracting bronze birch borer. In borer-prone areas, avoid spring pruning entirely. Prune in fall during dormancy. Dead limbs can be removed anytime. Cut to branch collar (swelling at base). For large limbs, use three-cut method to prevent bark tearing.

Pruning Rules

• Fall dormancy preferred.
• No spring pruning in borer zones.
• Three-cut method for large branches.
