King Palm Bark Exfoliation: Normal or Cause for Concern?

Peeling Bark on King Palms in Houston

Two established King Palms near a pool show loose, peeling bark at the base that pulls off easily. The owner wonders if this is natural exfoliation or a sign of decline.

Assessment

• If palms are not wilting and foliage looks healthy, peeling bark is likely normal exfoliation—many palms shed old bark as they expand.
• If wilting, discoloration, or stunted growth appears, investigate for Ganoderma butt rot, thielaviopsis trunk rot, or palmetto weevil damage.

Action

Monitor closely. Photograph the trunk monthly. If any signs of decline emerge, consult a palm specialist immediately. For now, maintain even moisture and fertilize with a palm-specific formula (8-2-12 + 4% Mg) in spring and summer.
