String Trimmer Damage on Young Apple Trees: Wound Care and Prevention

Immediate Response

1. Trim loose bark cleanly to sound wood with a sharp knife.
2. Do not apply wound paint—it traps moisture and delays callusing.
3. Mulch 3 inches deep in a 3-foot ring to create a "no-mow" zone.

Why This Works

Apples compartmentalize wounds naturally. Clean edges speed callus formation. Mulch prevents repeat injury and conserves moisture for recovery.

Long-Term Protection

Install tree guards or expand mulch beds to keep equipment away. Young bark is especially vulnerable.
