|The only way to control a tree's vertical growth is by cutting out the central leader. The central leader on a spruce is the tall single branch at the top of the tree (the part of the Christmas tree you would put a star on). Keep growth in check bypinching out new, light green growth (called "candles") on the ends of the branches in the spring.
