Pruning mature trees removes dead and dying branches to maintain plant health and safety
This pruning type is referred to as cleaning. For new plantings, see our page on the structural pruning of young trees.
Thinning and raising are two types of mature tree pruning that should be performed periodically to improve the form and shape of the plant, to eliminate interference with objects and structures, and to compensate for structural weaknesses. Research shows that thinning, the removal of live branches to reduce density, significantly reduces wind resistance and subsequent storm damage. Pruning of lower branches, know as raising, also can be used to increase the amount of light for turf grass and ground covers beneath the crown of a tree. Bartlett arborists are trained to evaluate the condition of your trees and determine the type(s) of pruning required to balance your goals and those of managing plant health and safety.
