How Arborists make pruning cuts on Trees

Making a proper pruning cut is crucial for the health of a tree. It helps avoid damaging the vascular system, which is essential for the tree's nutrient and water transport. Here are the steps to ensure you make the right cuts.

1. Understand the Vascular System

Before pruning, it's important to know where the vascular system is located. The vascular cambium is a thin layer of tissue just beneath the bark. Cutting into this layer can harm the tree's ability to transport nutrients and wound trees from being able to efficiently compartmentalize wounds.

2. Choose the Right Time to Prune

Pruning during the tree's dormant season (late winter to early spring) is ideal and recommend for certain species. This minimizes stress and allows the tree to heal before the growing season.

3. Select the Right Tools

Using sharp and clean tools is essential for making precise cuts. Common tools include:

• hand pruning shears

• electric pruning shears

• hand saws

• chainsaws

4. Use the Three-Cut Method

For larger branches, use the three-cut method to prevent tearing:

1. Make an undercut about 1/3 of the way through the branch.

2. Make a second cut from the top, slightly further out, to remove the branch.

3. Make a final cut just outside the branch collar to allow for proper healing.

5. Cut at the Right Angle

Always make cuts at a slight angle, away from the branch collar. This helps prevent water accumulation and reduces the risk of rot.

6. Monitor and Maintain

After pruning, regularly check the tree for signs of stress or disease. This ensures that the tree remains healthy and can recover from the pruning process.

Conclusion

By following these steps, you can make effective pruning cuts that preserve the vascular system of a tree, promoting its health and longevity.
