How to Prune
A cut when properly made should be done at an angle away from the remaining branch or trunk. The bark around the cut should be intact and should not have any tears. The cut should never run along the tree's trunk. This is called a flush cut and it can promote disease in your tree.
Remaining branches should not be cut flatly across the limb leaving stubs, this is called topping and it will promote undesirable and weak growths with a high potential for becoming projectiles in a storm.
Pruning methods affect the structure of a tree and are directly related to how the tree responds to the winds of a hurricane or a severe storm. All efforts must be made to maintain a tree structural integrity and to prevent for trees to become projectiles.
There are 2 types of pruning methods: those that promote desirable tree growths and those that promote hazardous conditions. Desirable methods include cleaning, thinning, raising, and reducing. Undesirable methods include topping, excessive lifting, and lion-tailing.
