Which method of pruning aims to maintain as many terminal buds as possible?

Directional pruning is a method that focuses on maintaining as many terminal buds as possible, which are essential for the overall health and structure of the tree. By preserving these buds, the tree has a higher chance of producing new growth in the desired direction, supporting a natural and aesthetically pleasing shape. This approach encourages lateral growth while minimizing the risk of stress on the plant, which can occur if too many buds are removed.

In contrast, rough pruning tends to be more aggressive and may remove significant portions of a tree, potentially affecting its health and structural integrity. Thinning pruning, while also beneficial, targets the removal of select branches to improve air circulation and light penetration rather than focusing on preserving terminal buds. Standard pruning is a more general approach that involves removing branches and leaves without a specific strategy to maintain terminal buds.

Through directional pruning, arborists effectively guide tree growth while maintaining the vital buds that contribute to its future development and resilience.
