Here are some examples of tree pruning projects that I commonly take on...canopy cleaning (the removal of larger diameter dead branches or damaged branches),  canopy lifting (raises the canopy over houses and driveways), and structural pruning  (corrects for architectural defects).  Canopy thinning will aid with light and air flow, improve disease resistance, and may help contain the overall growth.  Properly timed pruning cuts at the appropriate nodes will also improve fruiting and flowering.  Hazard mitigation (cabling and pruning) reduces the failure potential of branches and stems.    There have also been a few cat rescues!
