Pruning

Pruning can be beneficial or very harmful to trees. By using proper pruning techniques, tree structure can be improved, branch breakout can be reduced, and tree life can be extended. Unfortunately, improper pruning can make the tree very susceptible to pests and diseases by reducing the vigor of the tree and opening unnecessary wounds.

Traditionally, heading cuts were used to cut trees back quickly, in the theory that it would reduce the upward growth of the tree. Instead heading a tree actually causes more rapid upright growth of spindly growth. These branches tend to be badly attached and overcrowded. The wounds caused by heading cuts are also generally more susceptible to disease and rot than most other kinds of pruning wounds.

Thinning cuts have become the preferred method for pruning by directing growth rather than trying to restrict growth.
