Topping (also called hatracking) does not make a tree smaller. Although it may initially look smaller, a topped tree responds by quickly putting out a LOT of new, weakly attached (unsafe) growth. You'll be trapped in a vicious cycle of having to cut off more and more of your tree every year to try to keep it small - and the tree will push out more growth every year until it runs out of energy and dies. We do not top trees. No reputable tree service uses this outdated and ineffective "pruning" method.
