Crown Cleaning:
is the removal of dead, moribund, diseased, low
vigor, weakly attached branches and watersprouts
from a tree's crown.
Crown Thinning: is the selective removal of
branches to increase light penetration and air flow
through the crown.
Crown Raising: Removes
low growing branches of a tree to provide clearance
for pedestrians, vehicles, buildings and vistas.
When pruning for view, it is preferable to develop
spaces between branches, or "windows" through the
foliage of the tree, rather than to severely raise
or reduce the crown.
Crown Reduction:
Utilizes thinning cuts to reduce tree height and/or
spread by pruning back leaders to lateral branches.
Properly performed crown reduction can maintain the
structural integrity and natural form of the tree,
delaying the need to re-prune.
