A person who trims trees for a living must know the effect of apical dominance on the shape of trees?

A person who trims trees for a living must understand apical dominance, which is the phenomenon where the main central stem of a plant grows more vigorously than the side branches. This growth pattern influences the overall shape and structure of trees, as it determines how branches develop and compete for resources. Knowledge of apical dominance allows the trimmer to make informed cuts that promote healthier growth, enhance aesthetics, and maintain balance in the tree's form. Properly managing apical dominance can also help prevent issues like overcrowding and improve light penetration throughout the canopy.
