Maple Bark Peeling: Decay Fungi and Borer Prevention

Peeling bark with dark center indicates decay fungi from old borer wounds. Fungi don't kill living tissue but hollow the trunk over decades. Remove loose bark to aid compartmentalization.

Spray wound area with imidacloprid (Merit) to kill/prevent borers. Fertilize with 10-10-10 at 1 lb/inch trunk diameter now and fall. Tree can live years if canopy stays healthy.
