What Is a Tree Burl and its Fascinating Uses?
What Is a Tree Burl?
A tree burl is a rounded outgrowth on a tree, usually woody and deformed, caused by environmental factors such as injuries, fungi, bacteria, mites, viruses, and changes in the weather.
Burls can be small or large, and they are composed of many small fibers growing in different directions, making them very strong.
Common types of trees that develop burls include maples, oaks, elms, and willows.
Burls form around wounds on trees, protecting them from further damage and preventing the spread of diseases and pests.
They are often used in woodworking for their unique grain patterns and are not harmful to trees in most cases.

Did You Know?
1. Tree burls are considered abnormal growths that appear on the trunk or branches of trees. These burls are typically caused by stress or injury to the tree, such as infection or damage from insects or fire.
2. The unique texture and patterns found in tree burls make them highly sought after by woodworkers and artisans. The intricate figure and grain of burls are often prized for their aesthetic value, resulting in the creation of stunning furniture, bowls, and decorative pieces.
3. Burls can occur in various types of trees, but they are particularly common in oak, maple, and redwood trees. The growth of burls can significantly alter the appearance and structure of the tree, leading to a unique and often twisted shape.
4. Some tree burls can grow to massive sizes, with diameters reaching several feet. In extreme cases, burls have even been found that are larger than the tree itself. This makes them a challenge to harvest and work with, but also adds to their intrigue and value.
5. One fascinating aspect of tree burls is that they can contain dormant buds. When separated from the parent tree and provided with the necessary conditions, these buds can sprout into new tree growth. This characteristic has made burls a subject of experimentation in tree propagation and cultivation techniques.
What Is A Tree Burl?
A tree burl is a fascinating natural phenomenon found on various types of trees. It is a rounded outgrowth, typically woody and deformed, that develops near the base or trunk of the tree. Burls can vary in size, ranging from small knots to large, irregular growths. Despite their unconventional appearance, burls are highly valued in woodworking for their unique grain patterns and colors.
Formation And Composition Of Burls
The exact cause of tree burls is not yet fully understood, but they are believed to form as a result of disruptions in a tree’s growth hormones caused by environmental factors and stress. Burls are composed of numerous small fibers that grow in different directions, making them incredibly strong and durable. These fibers form a dense growth within the burl, which helps the tree protect against diseases, pests, and further damage. Within the burl, interconnected tubes called lenticels transport water and nutrients throughout the tree.
Common Types And Causes Of Tree Burls
Several types of trees, such as maples, oaks, elms, and willows, are prone to developing burls. Burls are formed as a response to various stressors, including injuries, fungi, bacteria, mites, viruses, and changes in the weather. When a tree encounters these stressors, it produces a localized growth that surrounds wounds, acting as a protective barrier against the spread of diseases and pests. Insect infestations, bacterial and fungal growth, mistletoes, and environmental injuries can also contribute to the development of burls.
Uses And Benefits Of Tree Burls
Tree burls have a wide range of applications and are highly sought after by woodworkers due to their unique grain patterns and colors. These burls are often used to create exquisite bowls, cutting boards, furniture, and other decorative items. The intricate patterns and textures present in burls provide a visually captivating and natural aesthetic to these woodwork pieces. Additionally, the strong and durable nature of burls makes them ideal for structural purposes in furniture and other woodworking projects.
Furthermore, burls have their benefits for the tree itself. They assist in protecting the tree from diseases, pests, and further injury. Burls also help maintain the health of the tree by facilitating the transportation of water and nutrients throughout its vascular system. In most cases, burls are not harmful to trees, but it is necessary to consult a professional tree care service if removal would cause a large wound and potentially harm the tree.
Tree Burl Vs. Burr Knot: Understanding The Difference
It is important to differentiate between a tree burl and a burr knot. While burls are rounded and woody outgrowths, burr knots are masses of small root initials that form along the trunk or branches of a tree. Unlike burls, burr knots can weaken the tree’s structure, stunt its growth, and provide entry points for insects and pathogens. Therefore, it is crucial to be able to identify the difference between these two formations to determine the best course of action for tree care.

Frequently Asked Questions
What is a tree burl worth?
The value of a tree burl can vary greatly depending on the species, size, and intricacy of its grain. For instance, a Cherry Burl can fetch anywhere between $98.00 to $4,100.00, while an Oak Burl can range from $95.00 to $2,795.00. These estimates demonstrate the potentially high worth of tree burls, making them sought-after items in the market for their unique and beautiful patterns.
What is special about burl wood?
Burl wood is highly sought after due to its exquisite grain patterns found in burl slabs. These patterns are simply mesmerizing, adding a distinct and unique beauty to any piece of wood. The most coveted burl wood typically comes from old-growth trees, which have no sapwood and are much older than younger trees. This adds to the allure of burl wood, making it even more special and prized in the world of woodworking and artisanal crafts.
Why is burl so expensive?
Burl wood commands a higher price tag due to its captivating beauty and inherent scarcity. It is a highly sought-after material as it is formed only when trees develop external burls, making it rarer to come by compared to other wood types. The intricate patterns and unique figuring found in burl wood contribute to its visual appeal, making it a prized choice for luxury furniture and artisanal crafts. The combination of its limited availability and stunning aesthetic qualities make burl wood a desirable and consequently more expensive option.
Is a burl a tree tumor?
No, a burl is not a tree tumor. Although they might share some visual similarities, burls are not harmful or cancerous like tumors. Rather, burls are harmless growths that develop in trees due to various external pressures or environmental factors. These unique formations can manifest on the tree’s trunk, branches, or even roots, adding an intriguing irregularity to the tree’s appearance.
