Lightning-Struck Pines: Fatal Diagnosis and Professional Assessment

Two large pines trimmed (one had broken dead branch, possible lightning). Now both completely brown. 30 ft apart. Owner asks cause and recovery.

Lightning in Pines

• Resin-rich = explosive steam damage, usually fatal.
• Hardwoods survive better.
• Current travels roots → can kill adjacent trees via root grafts.
• Signs: deep bark slits, spiral scars, root crown cracking.

Secondary Killers

Southern pine beetle rapidly colonizes lightning-weakened pines.

Action

• Trees likely dead (total browning).
• Contact state forestry agency for free forester confirmation.
• Remove promptly to prevent beetle spread.

No recovery from total crown browning in conifers.
