Most limbs in the lower 15 to 20 feet of shade trees will be removed eventually. Preventive arboriculture keeps them small by pruning lateral branches from them and shortening them to minimize the wound when they are eventually removed. On some tree types, removing small lateral branches from the base of the limbs causes main limbs to grow more upright, at least for a number of years. This encourages main limbs to grow faster because they have access to plenty of light at the top of the canopy.
