The Perfect Time to Harvest Tree Burls - Techniques and Considerations

Tree burls, or gnarled growths on the trunks and roots of trees, are highly valued for their unique textures and intricate patterns. However, the best time to harvest them can significantly impact the tree's health and the quality of the burl. This article provides comprehensive information on the ideal timing, precautions, and techniques for harvesting tree burls to ensure both the health of the tree and the quality of the burl.

When is the Best Time to Harvest Tree Burls?

The best time to harvest tree burls is during the dormant season, which typically occurs in late autumn or winter. During this period, the tree has shed its leaves and is not actively growing. Harvesting at this time minimizes stress to the tree, reducing the risk of disease or insect infestations. It is crucial to verify local regulations and obtain any necessary permits before proceeding with the harvest to protect tree populations and ecosystems.

Preparation and Techniques

The process of harvesting burls begins by obtaining the necessary permissions. This is especially important to avoid illegal harvesting and to ensure the health of the tree. Once permission is granted, it is advisable to act swiftly, as others may seek to harvest the burls. After harvesting, sealing the cut face promptly with melted paraffin wax is essential. A plastic sandwich wrap can serve as a temporary seal until the paraffin wax can be applied.

Burls grow in a way that causes the wood to develop randomly from rampant bud growth, similar to cancer in animals. Some burls, such as the Amboyna Burl, are particularly valuable and require specialized slow-drying techniques. When dealing with burls, it is important to handle them with care to preserve their intrinsic beauty and integrity.

Harvesting from Dead Trees vs. Living Trees

While burls can be harvested from both dead and living trees, the choice depends on the specific burl and the tree's condition. Harvesting from a dead tree can be beneficial, especially for species like salt cedar, which have natural resistance to decay. However, for most species, it is advisable to harvest from living trees. Cutting a burl off a living tree exposes the tree to decay and increases the risk of introducing diseases or insects to the area. To minimize the risk, it is essential to remove only the burl that is already detached or semi-detached from the tree. This helps maintain the tree's health and integrity.

Post-Harvest Care

After harvesting, it is crucial to seal the cut face with melted paraffin wax to prevent cracking and preserve the burl's integrity. If immediate access to melted paraffin is not available, a plastic sandwich wrap can serve as an interim measure until the wax can be applied. For special care, burls like the Amboyna Burl require slow-drying techniques to prevent cracking and maintain their natural beauty.

Conclusion

The time to harvest tree burls may seem straightforward, but it involves several considerations to ensure the health and longevity of the tree, as well as the quality of the burl itself. By understanding the ideal timing, preparing appropriately, and handling the burls with care, you can harvest them effectively while maintaining the tree's health and the burl's value.
