Crown Cleaning a tree involves pruning the deadwood, diseased, and dying limbs out of the canopy of a tree. This type of pruning is extremely beneficial for the health and promotes longevity for a tree.
Crown Thinning a tree involves lightly pruning the interior limbs of at tree canopy. Generally, this is done to achieve more sunlight on a customer’s lawn, or to prevent storm damage. Lightly thinning the interior allows for wind flow to better flow through the canopy, thus reducing chances of limb failure in a storm. Usually it is recommended to only cut approximately 10-15% of the live growth in the interior, and to avoid lion tailing.
Crown Raising a tree involves elevating or cutting the lower limbs of a tree canopy. This type of pruning is usually done to achieve visibility, or to allow lawn mowers to be able to mow grass underneath without a tree limb in the way, or anything else such as cars and people to be able to pass underneath the trees canopy.
Crown Reducing a tree involves lightly thinning out the top of a trees canopy. Do not mistake this for tree topping. Topping is NOT a recommended pruning method and should be avoided. A proper crown reduction will reduce the overall crown height and canopy, without altering branch integrity. This type of pruning minimized storm damage, and reduces the chances that larger taller trees from falling or uprooting in a storm.
Shaping a trees canopy should really only be done on shrubs and bushes – not trees. Larger trees can be shaped but only by a selective prune with proper cuts – not topping. Small shrubs and bushes like Holly trees, bush hedges, and other shrubs and bushes can be shaped how you like them. Some green should always be left or the plant has been shaped to hard and faces the chance of declining. Hand shears are usually used when shaping is completed.
