What Is a Tree Burl?
Burls are tree growth abnormalities that typically form around a tree’s base. Although scientists haven’t uncovered the root cause of tree burls, many believe they develop when trees experience severe stress that disrupts their growth hormones, creating abnormal cell development. The cells generate unusual growths known as burls.
Burls can develop on any tree species but primarily affect:
- Ash trees
- Oak trees
- Cherry trees
- Maple trees
- Walnut trees
- Elm trees
Although most burls develop along a tree’s trunk and limbs, some can grow underground. Experts call these burls lignotubers.
Lignotubers are much larger than traditional burls and can weigh over 500 tons. They can also reach up to 45 feet in diameter.
Can Burls Harm Trees?
When asking, “What are tree burls?” most people want to know if they’re harmful.
Although burls might hinder a tree’s appearance, they won’t impact its health. They often act like tree calluses and develop over wounds to prevent further damage. Although removing them might improve the tree’s visual appeal, it often causes more harm than good and increases the chances of disease and pest infestations.
Many woodworkers seek burlwood due to its unique grain patterns and captivating color formations. Burlwood colors range from dark brown to light chocolate and have unreplicable grains, making burlwood one of the most sought-after woodworking materials.
Burlwood uses range from veneer panels to instrument making. Below are a few things woodworkers create from tree burls:
- Furniture slabs
- Cutting boards
- Barkcloth (a type of fabric)
Understanding the Difference Between Tree Burls and Burr Knots
Many Citrus Heights residents confuse tree burls with burr knots. Although these timber anomalies look similar, they affect trees differently.
Unlike tree burls, burr knots are incredibly harmful to trees. They are relatively large masses of root initials and can significantly weaken a tree’s structure. Burr knots also cause stunted growth and make great entry points for tree pests and diseases.
You must remove burr knots before they adversely affect the tree’s health and structural integrity. However, it’s best to contact a professional arborist to eliminate the burr knot and minimize trauma.
Our team at Ace Tree Service can help you identify burr knots and tree burls and will handle all your tree care needs at a price that won’t break the bank.
