Deer Antler Damage on Red Maple: Emergency Response

Complete bark removal around a 20-inch trunk section (girdling) on a 4-6" diameter red maple is likely fatal. The vascular tissue (phloem) that transports sugars from leaves to roots is severed.

Last-Resort Interventions

• Merit (imidacloprid) spray: Prevents borer entry into exposed wood
• Grafting wax: Seals wound against desiccation (some success reports)
• Remove loose bark: Clean edges promote callus formation
• Tree wrap: Prevents further rubbing

Realistic Assessment

• If girdling is truly complete (360°), survival unlikely
• Check for any intact bark bridges—even narrow strips transport sugars
• Bridge grafting (advanced) can reconnect vascular tissue
• Monitor for leaf-out next spring—definitive test

Contact a certified arborist immediately for bridge grafting evaluation. If any bark remains connected, the tree may survive with protection.
