Why is Your Tree Losing Bark?

It is quite normal for a tree to lose bark, especially for some species like silver maple, sycamore, and birch. Shedding large chunks of bark is part of the tree’s allure. Trees like oak, pine maple and ash develop from the inside out, causing older bark to chip away making room for new bark.

When bark peels off a tree, determine whether the tree is going through a normal shedding process or if injury or disease is causing the problem. If you see bark covering the wood after the old bark peels away, the tree is probably undergoing a normal shedding process. If you see bare wood or mats of fungus under the peeling bark, the tree is suffering from environmental damage or disease.

If healthy bark is underneath peeling layers, then your tree is okay, but here are a few signs that may signal a problem with the tree:

  • Bark falls off after a frost. This usually appears on happens on the tree’s the south or southwest side. A sudden drop in temperature can make a tree shed bard and crack under stress.
  • Bark falls off after an excessive heat spell. Like frost damage, the heat strips back down into the wood.
  • Bark falls off an unhealthy tree. Most likely, you will see other signs of stress such as cankers, sap or dead twigs and leaves.

Trees with splits in the bark can live for many years if the damaged area is narrow. Hardwood trees that have peeling bark may be suffering from a fungal disease called Hypoxylon canker. Peeling bark caused by this disease is accompanied by yellowing and wilting leaves and dying branches. Additionally, the wood under the peeling bark is covered with a mat of fungus. As there is no cure for this disease, the tree should be removed, and the wood destroyed to prevent the spread of the fungus. Cut down the tree as soon as possible to prevent damage and injury from falling branches.
