Our method of pruning is recommended by the National Arbor Day Foundation and the International Society of Arboriculture. It is the accepted industry pruning standard. Initially, your trees may look different after pruning. But directional pruning is actually better than other pruning methods for safety and the health of your tree. Here's why:
Directional, or target pruning involves removing only those limbs that will come in contact with energized conductors. It removes branches at a joint, or lateral, of a limb, where the tree would be likely to lose a branch under natural conditions. At this lateral, the tree's natural defenses protect against decay and disease.
Directional pruning reduces the number of times the tree must be pruned, reduces the number of fast-growing and weakly attached sprouts, and by directing growth away from the power lines, allows the tree to achieve its natural height and shape. With less desirable methods of pruning -- round-over or topping -- all tree limbs are cut back to stubs or small branches, eliminating foliage and buds containing next season's growth. This stimulates the production of vigorous, crowded, poorly tapered and weakly attached shoots, also called water-sprouts. The cut stubs are prone to decay and the water-sprouts are susceptible to breakage. Round-over and topping can weaken trees and make them less resistant to pests, while destroying their natural structure and aesthetic value.
