How do you prune an overgrown evergreen shrub?

One method is to prune them back over a 3-year period. Begin by removing one-third of the large, old stems at ground level in late winter/early spring (March or early April). The following year (again in March or early April), prune out one-half of the remaining old stems. Also, thin out some of the new growth.
