Birch Recovery After Ice Storm: Sap Flow and Borer Prevention

Unbroken but bent birch limbs leaking sap will recover. Sap flow is normal in spring and decreases with heat. Do not prune live branches May–July—peak bronze birch borer flight. Females are attracted to fresh wounds.

If pruning is needed, do it in fall dormancy. Apply imidacloprid (Bayer Advanced) as a soil drench now to protect against borers while wounds heal. Avoid wound dressings. Limit canopy removal to 25%. The tree should recover fully with protection.
