Burl Max is a specialized horticultural product designed to encourage the development of burls on selected trees. Burls are distinctive, woody outgrowths that appear on tree trunks, branches, or roots, prized by artisans and woodworkers for their unique, convoluted grain pattern. This unusual wood is often used in furniture, decorative items, and veneers.
The Science Behind Burl Max
Burl Max influences the tree’s internal physiological mechanisms, specifically targeting the vascular cambium. Burls typically form as a result of hyperplasia, an abnormal proliferation of xylem production by this growth tissue. The product contains a precise blend of plant growth regulators, like modified auxins and cytokinins, along with non-pathogenic microbial stimulants. These compounds mimic the natural triggers that lead to burl formation, prompting the tree to initiate a controlled, localized growth response.
This intricate interaction disrupts the tree’s normal hormone balance in a specific area, redirecting cellular energy and resources. The microbial component may signal a benign stress response, further encouraging the cambium to produce dense, irregularly patterned wood tissue rather than straight-grained growth. This guides the tree into forming the characteristic interlocked and swirling grain patterns prized in burl wood.
Applying Burl Max
Clean the bark surface thoroughly where burl development is desired, removing any loose debris or algae. Create small, shallow access points into the tree’s cambium layer, drilling holes approximately 1/8 inch in diameter and 1/4 inch deep. Space these points 1 to 2 inches apart in a grid pattern over the intended burl area.
Burl Max can be injected directly into each hole using a fine-tipped applicator or painted onto superficial incisions. A small amount, typically a few drops or a thin coating per point, is sufficient. The optimal time for application is during the tree’s dormant period, either in early spring before bud break or in late fall after leaf drop. Always wear appropriate personal protective equipment, including gloves and eye protection, when handling the product.
Choosing the Right Trees
Certain tree species are more predisposed to developing burls naturally, making them ideal candidates for treatment. These include maples, oaks, elms, walnuts, cherry, ash, and redwood.
Healthy, well-established trees with good vigor respond best. Avoid young, immature trees or those showing signs of stress, disease, or pest infestation, as treatment could further compromise their health. The trunk diameter should be at least 8 to 10 inches to ensure sufficient cambium tissue for burl development without unduly stressing the tree. Consistent soil moisture and protection from extreme conditions also contribute to a favorable response.
Expected Growth and Care
After Burl Max application, visible signs of burl development typically begin within 1 to 2 years, appearing as slight swellings or irregularities on the bark. Burl growth rate varies significantly with tree species, overall health, and environmental conditions. While initial formation may be quick, achieving a substantial size for woodworking can take 5 to 10 years, or even decades for larger burls.
Burls gradually enlarge, developing their characteristic irregular, rounded shapes and distinct bark textures. Post-application care involves maintaining the tree’s health through adequate watering, especially during dry periods, and ensuring proper nutrient availability. Avoid further wounding or unnecessary stress to the treated area. Burls generally do not harm the tree, as they are benign growths the tree compartmentalizes.
