How is Plant Resin Extracted from Trees?

Traditional Resin Extraction

The classic way to harvest resin involves making deliberate cuts or grooves in the bark of resin-producing trees such as pine or spruce. The wounds encourage the tree to release sticky sap as a protective response, which then slowly gathers at the exposed area. This exuded resin can be collected manually after it has thickened, sometimes using simple tools or collection containers attached beneath the cut.

Modern Tapping Methods

Today, some commercial operations refine this process by using specialised tools that create precise incisions, sometimes combined with removable collection cups or strips to channel the sap efficiently. Care is taken to avoid deep damage to the tree, allowing for repeated harvesting over time while ensuring tree health. Whether for industrial supply or smaller scale projects, methodical tapping and regular collection yield cleaner resin with minimal impact on the tree.

Tips for Responsible Resin Collection

• Select mature, healthy trees and space out the tapping points to minimise injury.
• Use sharp, clean tools to make shallow cuts for sap flow, but never ring the entire trunk.
• Collect resin before it hardens fully, and allow time for the tree to heal between harvests.
