Globe Willow Bark Peeling and Borers: Water Stress Is Root Cause

Borers Attack Stressed Willows

Bark peeling in patches + borers + fine frass = drought stress. Willows need constant moisture.

Treatment

• Spray trunk with Merit (imidacloprid) for borers.
• Water 1 in. weekly (pan method).
• Mulch 3 in.

Bark peeling stops when borers controlled and tree hydrated. Normal aging bark change is uniform, not patchy.
