What should you avoid when pruning branches with a narrow angle to the trunk?

When pruning branches that have a narrow angle with the trunk, it is crucial to avoid leaving included bark. Included bark occurs when the bark at the branch junction is trapped between the trunk and the branch. This often leads to structural weaknesses in the tree as it can create a point of potential decay and failure. The narrow angle can encourage the development of included bark due to the way the branch and trunk grow together.

By properly managing included bark during pruning, you ensure that the cut promotes better healing and structural integrity. This can also facilitate healthier growth, as it reduces the risk of disease entering through the wound created by the cut. Maintaining the health of the tree and its branches is paramount for longevity and stability, making it essential to avoid leaving included bark during the pruning process.
