Do you notice unsightly bulges on your tree? What’s the deal with these tumor-like protrusions? These are called tree burls. Arborists know about the biology of burls. We will share with you what we know and whether their presence calls for emergency tree service.
Tree Burls at a Glance
Bark cover the burls just like the rest of the trunk. This may be a sign of disease; the tree produces the burl to isolate the infection. It may also produce the burls in response to physical stressors, such as trauma or frost damage.
The tree’s ability to produce a burl is a good sign that it has the defensive mechanisms to protect itself.
Are Burls a Cause for Concern?
For the most part, a burl or two isn’t a cause for alarm. However, some burls may start at the trunk and extend to the branches. This may cause undue stress, causing branches to break apart. When we remove a tree, we often spot signs of enlarged burls that encapsulate part of the branches.
Should You Remove a Burl?
If a burl appears on a prune-able part of the branch, then you can remove it by pruning the branch. Otherwise, we do not recommend any attempts at removing the burl. Doing so may create an open wound prone to infections.
As mentioned, however, trees produce burls in response to infections. This means your tree may have a serious fungal disease or an intrusion from burrowing insects. You should bring in a tree care expert to look for early onset of disease.
