10 11 Renewal Pruning a Dogwood Hedge

Renewal pruning is a combination of heavy and light pruning. Most of the spring-flowering shrubs bloom best on young branches that are two to four years old. To promote the best flowering in the shrubs, prune out the branches that are older than four years. Older branches are more susceptible to insects and disease. Removing whole branches at ground level opens the interior of the plant for more air movement and sunlight to reach the inside, which will help prevent disease. Renewal pruning can be used on deciduous shrubs like forsythia, honeysuckle and viburnum and on broad-leafed evergreen shrubs like azaleas, pyracantha and hollies.
