If you notice a large, knobby lump on your trees, don’t sweat. It’s probably just a harmless growth typically known as a burl. What causes a burl in a tree? Is a burl harmful?
ECO Tree Experts, your go-to tree service in Palm City, explores burls, how they form, trees more likely to grow burls, and more.
What Is a Burl?
A burl refers to a large woody, rounded swelling of callus tissue typically found near the base or trunk of some trees. Burls can grow on any tree species but tree species most likely to develop burls include:
- Walnut
- Elm
- Oak
- Ash
- Cherry
- Maple
What Causes Burls on Trees
While experts have been unable to determine the exact causes of a tree burl, people generally believe that burls form where stress disrupts tree growth hormones, causing abnormal cell development. As a burl grows, it incorporates the tree’s undeveloped buds.
Burls may develop because of environmental injuries, mistletoes, bacteria and fungi growth, and insect infestations.
Are Burls a Danger to Trees?
Contrary to popular belief, you have no reason to remove burls as they don’t harm the tree in any way. In fact, they often help keep the tree alive by forming over injuries. Burl removal could leave the tree with a massive wound that would expose the tree to undue stress and potential death.
If you have an unhealthy burled tree or the burl’s shape has become a hazard, contact a certified arborist to inspect the tree for potential removal.
How to Identify Burls
After knowing what causes a burl in a tree, it helps to know how to identify them. Keep an eye out for the following symptoms of a burl:
- Areas of swelling bark
- Woody, cracking bark irregularities around a tree trunk or branches
- Areas of swelling bark
- Irregular bark patterns
Not sure whether your tree has a burl or something more troublesome? Contact a certified arborist for a consultation and assessment. A seasoned tree care expert will analyze your tree’s health and determine the best course of action.
Applications of Burls
