Lightning Strike on Oak: Assessment and Care

A lightning strike that strips a 30-foot strip of bark from your white oak is alarming, but the tree can survive with proper care.

Immediate Actions

• Trim loose bark: Use a sharp knife to carefully remove any hanging bark or splinters back to where it's firmly attached. This prevents insect entry and promotes callus formation.
• Do not apply wound paint: Research shows it traps moisture and hinders natural healing.
• Water deeply: Provide 600 gallons per week (equivalent to 1.5 inches of rain) over the root zone during dry periods until fall.

Long-Term Monitoring

Much lightning damage is internal and invisible. Watch for signs of decline: early fall color, dieback, fungal conks, or bark separation. If the tree was already stressed, survival odds decrease. Consult a certified arborist (Georgia Arborist Association) for a professional risk assessment.

With good care, many oaks compartmentalize the damage and live for decades.
