What type of buds are the primary focus of directional pruning?

The primary focus of directional pruning is on terminal buds due to their importance in influencing the growth and shape of the tree. Terminal buds are located at the tips of stems and branches, and they play a crucial role in determining the direction of new growth. When terminal buds are removed or manipulated during pruning, it encourages growth from lateral buds below, allowing arborists to shape the tree and manage its height and width effectively.

By focusing on the terminal buds, arborists can direct how the tree grows and trains it to develop a structure that is more balanced or better suited for its environment. This method is particularly useful for utility arborists who must manage trees in proximity to power lines or infrastructure, as it helps maintain safety and aesthetic considerations. This approach differs from other types of buds, which either do not contribute significantly to overall growth direction or serve different purposes, such as flowering.
