Tree Pruning should be performed per the ANSI A300 standards to ensure that your tree maintain its health.
Maintenance pruning is the process in which dead, dying, diseased, crossing branches are removed, depending on the species and health.
Hazard reduction pruning is the process in which larger deadwood is removed for safety.
Vista pruning is performed when there is a view that the tree branches are blocking, this can be performed by selectively removing limbs without injuring the tree.
Crown raising is the process in which the lower branches are removed, most commonly in areas where there is a driveway, walk-way, or parking area.
Crown reduction is pruning less than 1/3 of the tree's crowns or for the purpose of shaping.
Crown Thinning is selectively removing inner branches to increase light penetration, air movement and reduce branch weight.
Pruning cut back branches from structures such as sidewalks, lights, and building.
Fine pruning is most commonly performed on smaller or immature trees that have smaller branches and deadwood.
Pruning cuts should not have dressing or paint to cover the cuts, this was a misconception that is still in practice today.
Proper PPE should be worn at all times during the pruning process.
