Trim curly ligustrum branches to shape the plant as desired. Many gardeners shape a curly ligustrum like a Christmas tree with the top branches smaller than the bottom branches and others shape it like a shrub. Cut the branches just above the leaf nodes with a pair of sharp garden clippers.
Cut the lower side stems off at the trunk. This style of pruning makes a curly ligustrum appear more like a tree with an exposed trunk rather than a shrub. Use a pair of garden clippers to make clean cuts flush against the trunk.
Prune wayward or misshapen curly ligustrum branches, as desired. Cut the branches just above a leaf node with a pair of garden clippers.
Cut back an overgrown curly ligustrum that is too large for its space. Prune it all the way back so it only stands 2 or 3 feet from the ground, cutting stems back to parent branches or leaf nodes. According to North Carolina State University, a curly ligustrum will recover from a severe pruning like this in two or three years.
