Proper Tree Trimming Style
BrightRidge tree trimming guidelines have been carefully designed to reflect the recommendations of urban foresters and experts from the National Arborist Association and the International Society of Arboriculture. Most utility companies now use the cost saving pruning methods outlined below that comply with ANSI A300 standards.
Crown reduction removes the main leader(s) to a suitable lateral branch. This type of pruning is suited to slow growing trees located directly under the lines. If fast growing trees such as silver maple, poplar, sweet gum, sycamore, and willow are located directly under power lines, they should be considered for removal.
“V” pruning is used for fast growing trees located directly under power lines when removal or crown reduction is not an option. No branches are left hanging over the lines with V pruning.
Side pruning involves pruning the branches growing toward the lines on one side of the tree only. Any tree that has its base located 15 feet or more away from the center line of BrightRidge conductors will be side pruned.
“L” pruning is practiced when tree limbs cannot be pruned to a suitable lateral. This method of pruning involves pruning the branches which grow toward power lines on one side of the tree only.
