Red Oak Bark Splits After Record Rain: Normal Growth Response

A 29-year-old red oak in West Texas has long bark splits on trunk and branches after record rainfall. Crown is healthy.

Assessment

Splits are likely rapid growth cracks from abundant water and prior pruning. No oozing or discoloration = no fungal canker.

None needed. Monitor crown health. If foliage stays green, the tree is fine. Bark will eventually callus over.
