Abstract
Black cherry trees 4 to 6 inches in diameter at breast height (dbh) with live crown ratios ranging from 73 to 92 percent were pruned to 25, 50, or 75 percent of tree height or were left unpruned. Most trees can be pruned to 50 percent of tree height in one operation. Trees that have large crowns and that are frilly exposed on the southwest side should be pruned less severely. Pruning to 75 percent of tree height caused excessive epicormic branching, poor diameter growth, and serious cambium necrosis.
