Why do oak trees lose their bark

This disease is common among many types of oak, but usually post oak, water oak, southern red oak, white oak, and blackjack oak are impacted the most.

In fact, hypoxylon canker can attack the bark of just about any hardwood tree. The disease causes bark to slough off the trunk and branches, revealing brownish fungal spores that eventually turn silvery gray and black.

Crown dieback is often an early symptom of the disease. The disease cannot be managed once it spreads to the trunk; infected trees should be removed and burned or otherwise disposed of.

The goldspotted oak borer is a boring insect that produces damaging larvae that feed on woody tissue, causing bark to crack and ooze with sap. Pulling back weakened bark may reveal dense colonies of larvae, dust, excrement and pockets of sap. Holes in the bark, which the adult insects enter and exit the tree from, are primarily located on the lower 10 feet of the trunk, though they may also be on large branches. Diseased trees must be burned or cut down.
