Car Impact on Maple: Bark Stripping Repair and Borer Prevention

Repair Steps

1. Trim loose bark to clean edges.
2. No wound paint—slows healing.
3. Spray Merit (imidacloprid) on wound to deter borers attracted to fresh sap.

Why Merit?

Borers target stressed/wounded trees. A preventive spray on the wound area protects during the vulnerable healing period (spring/summer). Fall/winter wounds are less attractive to borers.

Long-Term

Maples compartmentalize well. Callus will roll in from edges. Monitor for decay fungi (conks) years later, but initial recovery is typically full.
