Why is Bark Falling off My Tree (Oak, Pine, Ash, Maple)?

Why is Bark Falling off My Tree (Oak, Pine, Ash, Maple)?

Full canopies, plump fruit, thick bark—all these things describe a healthy tree. But what happens when one is missing?

If your tree is missing chunks of bark, it may not look so hot. But does it mean something’s wrong?

If you spot peeling bark on your tree, help it out by learning about the causes—and solutions—below.

 

 

Why is my tree losing its bark?

Usually, it’s normal for a tree to lose bark. For some species, like sycamore, silver maple, and birch, shedding large chunks of bark is just one of their charms! Other trees, like oak, pine, ash, and maple, develop from the inside out, so the older bark on top chips away to make room for new bark.

As long as there’s healthy bark underneath the peeling layers, your tree is OK. But if you see these other signs, your tree needs a bit more help:

  • Bark falls off after frost, which usually happens on the tree’s south or southwest side. Any sudden swing in temperature can make trees shed bark and crack under stress.
  • Bark falls off after excessive heat, which, like frost damage, strips bark down to the wood.
  • Bark falls off an unhealthy tree, which means you’d see other signs of stress such as cankers, sap, or dead leaves and twigs.

If bark is falling off my tree, is it dying?

Sadly, there’s no easy yes or no to this question. But, if the tree appears overall healthy, there’s a good chance it’s just peeling for growth. If your tree lost bark after an unusual weather incident, you can usually save it with the below steps! The biggest question is if you spot other worrisome signs that point to other bigger problems.

What to Do About Pine, Maple, Oak or Ash Tree Bark Falling Off

If bark is peeling with no other symptoms, it’s likely because of weather stress. Stressed trees love water and mulch! So, hydrate the tree when its soil is dry and apply organic mulch in spring and fall.

If your tree looks unhealthy, give it a closer look. A host of tree pests and diseases can affect your ash, pine, oak or maple. There’s the infamous EAB that burrows underneath ash tree wood and the smooth patch disease, a fungus that attacks the outer layer of oak bark.

If you find any signs of pest or disease—sawdust, oozing cankers, dead leaves, or a fuzzy fungus—have a professional arborist check it out. He’ll let you know if you can treat the problem or if you need to remove it to keep other plants on your property out of harm’s way.

  • Thomas Surlas July 14, 2018 >We have two large maples. One on either side of our parking area seperated by a six foot patch of grass and 35- 40 feet of gravel where we park 3 cars. One looks completely normal, but; the other looks like it is dead because of the dry looking barron branches only on the east side of the tree. To cut off the ugly branches would disfigure it. Any suggestions?

  • Gwen Hammonds May 6, 2018 >My maple and oak trees are dying . I have lost 4 large oak trees, 2 maple tress and now my formosa is bare, no leaves in May 2018 in NC. I did notice some signs of insects, bark peeling and leave appear as if they are burned. Can I treat this or will I loose all my other trees?
  • The Tree Doctor April 30, 2018 >Hi Richard, The heat from the flames likely killed the cambium layer just under the bark. This thin cell layer generates the new tissues that form the new growth ring each spring. The extent of the damage will depend on how wide/long an area of the cambium was damaged. Where the cambium is still alive at the margins of the wound, new wood will be able to form as the tree attempts to seal off the damaged area. The loose bark over the dead area can be carefully trimmed back to live wood to assess the amount of damage caused by the fire and/or to clean up the wound. I suggest you contact a Certified Arborist in your area to take a look at your tree if you do not feel comfortable with trimming back the wood yourself.

  • The Tree Doctor January 25, 2018 >Hi there, Keith. Oak trees will often shed lower branches as they age to manage their energy needs. However, many insect and disease issues can result in branch death, too. It is best to have a certified Arborist evaluate your tree to make the proper diagnosis. Hope this helps, Keith.
