Directional pruning*, also known as the “Shigo Method”*, is a healthy way to ensure the tree does not grow into the power lines. After directional pruning, the tree will be less susceptible to pest and decay issues. Branches will be less likely to drop during a storm, improving safety and reliability. Directional pruning is the accepted industry standard endorsed and promoted by the National Arbor Day Foundation and the International Society of Arboriculture.
