Each tree cut has the potential to change the health and growth of a tree and as such no branch should be removed in the
incorrect manner and without a reason. Common pruning goals are to improve tree structure or
health or accommodate human need such as site line pruning or hazard mitigation.
Proper pruning cuts must be made with a thorough understanding of tree anatomy and of how the tree will respond to the cut.
The amount of live tissue that should be removed depends on the tree size, species, age, and pruning objectives. Each cut,
and depending on the time of year and maturity, can change the growth of a tree. Improper pruning
and timing can cause life-long damage to a tree.
Crown cleaning is the selective removal of dead, dying or diseased, broken or
weakly attached branches from a tree crown. Regular pruning should correct small growth problems
before they develop into large problems.
