What is the primary purpose of subordination in tree pruning?

Subordination in tree pruning is primarily focused on reducing the size and growth of a branch in relation to others. This technique is essential for encouraging a well-structured canopy by selectively shortening or trimming back larger branches. By doing so, the growth rate of subordinate branches is increased relative to the dominant branches, which helps to create a balanced crown that allows for better light penetration and air circulation. This process can improve the overall health and vitality of the tree, fostering a more aesthetically pleasing appearance as well.

While enhancing the aesthetic appearance of the tree is a benefit of good pruning practices, it is not the primary purpose of subordination. The main intention revolves around managing branch size and growth dynamics. Additionally, increasing the overall height of the tree or promoting the growth of flowers and fruits are not objectives associated with subordination; these goals may be achieved through other pruning techniques that serve different purposes.
