If you want to keep your trees healthy and beautiful, mastering the three step pruning method is essential. This technique, developed by Dr. Alex Shigo, a renowned plant pathologist and the father of modern arboriculture, focuses on making precise cuts that promote healing while minimizing damage to the tree.
Dr. Shigo’s research revealed that effective pruning should prioritize the removal of branch tissue without harming the stem or bark. By doing so, the risk of decay in the stem tissues is significantly reduced. The living cells surrounding the wound can heal quickly, leading to the formation of a protective callus over time. Initially, his findings faced skepticism, but they have since transformed tree care practices across the industry.
To apply the three step pruning method, follow these simple steps:
1. Start by locating the branch collar, a bulge found at the base of the branch, and the branch bark ridge, a ridged line of bark at the tree’s crotch.
2. The first cut should be made on the underside of the branch, just outside the branch collar. Create a shallow notch without cutting all the way through to prevent tearing as the branch falls.
3. Next, make the second cut from the top of the branch, one to two inches outside the first cut. This cut removes the weight of the branch, allowing for a safer final cut.
4. The third cut removes the stub, made just outside the upper branch bark ridge and angled downwards away from the branch collar. This final cut encourages the formation of a protective callus over the wound.
It’s crucial to avoid damaging the branch collar or branch bark ridge during any of these cuts, as this can hinder the tree’s ability to seal the wound, leaving it vulnerable to disease and decay. Always ensure that stubs are removed after the second cut to promote optimal healing.
By mastering the three step pruning method, you can help your trees thrive while enhancing the beauty of your landscape. Remember, proper pruning is not just about cutting; it’s about understanding tree biology and ensuring their long-term health. Happy pruning! 🌿🌼
