What technique should be employed to ensure a clean cut on branches when pruning?

To ensure a clean cut on branches when pruning, using sharp and clean tools is essential. Sharp tools make it easier to slice through the wood fibers without tearing or crushing them, which can lead to jagged cuts. A clean cut minimizes damage to the bark and promotes faster healing for the tree, as it helps to prevent disease and pests from entering the wound.

In contrast, cutting through multiple times can create uneven surfaces, increasing the chances of damage and slowing the healing process. Applying pressure to crush the branch before cutting can cause injury to the tree and can lead to an unsightly cut that is more prone to infection. Additionally, making rough cuts may seem efficient in the short term, but this approach can lead to more extensive damage and a higher likelihood of health issues for the tree in the long run. Keeping tools sharp and clean is fundamental in horticultural practices, as it not only improves the quality of the cut but also reflects an understanding of good tree maintenance practices.
