Pruning is necessary on mature trees to remove dead and dying branches, which is essential for maintaining plant health and safety. This type of pruning is known as “crown” cleaning. Recent research has shown that thinning, the removal of live branches to reduce density, is an effective way to reduce wind resistance and prevent storm damage. However, thinning should only be done on trees with a dense crown. The outer portions of the canopy should be thinned while as many branches as possible should be left on the interior crown.

Sometimes, the crown or individual branches need to be reduced in length to improve the plant’s form and shape, eliminate interference with objects and structures, and compensate for structural weaknesses. Lower branches may require pruning for the same reasons. This process, known as raising, can also be used to increase light for turf grass and ground covers beneath the tree’s crown.

Arborists are trained to assess the condition of your trees and determine the best type of pruning needed to balance your goals and manage plant health and safety.
