Lightning Strike on Russian Olive: Wound Care and Recovery

Immediate Actions

After a lightning strike removed a 6-inch, 18-foot branch from a 24-foot Russian olive (Elaeagnus angustifolia) in SE Michigan:

Clean the wound: Trim splintered wood smooth.
Do NOT apply paint/sealer. Let the tree compartmentalize naturally.
Insect prevention: Spray exposed wood with a borer insecticide (e.g., permethrin) to deter borers.

Outlook

The tree will gradually callus over the wound. Russian olives are tough and often survive lightning strikes. Monitor for dieback or fungal fruiting bodies.
