What is the purpose of a pruning cut in branch removal?

The purpose of a pruning cut, particularly when removing branches, is designed to minimize damage to the parent stem while ensuring that the overall health of the plant is maintained. In the context of removing one of two branches at a union, the focus is on delicately removing the smaller branch. This approach mitigates the risk of harm to the larger branch and the parent stem, allowing the latter to continue thriving without the internal stress that could arise from an improper or aggressive cut.

By making a careful cut at the junction of the smaller branch, the goal is to preserve the structural integrity of the tree or shrub, encouraging healthy growth while also allowing for better air circulation and light penetration in the affected area. It also helps in redirecting the plant's energy toward the remaining branches, fostering stronger and more balanced growth. This technique exemplifies best practices in horticulture aimed at enhancing the longevity and aesthetics of the plant.
