Richard Hentschel continues the pruning series by discussing renewal pruning of shrubs in the home landscape. Renewal pruning allows a portion of the existing branch structure to remain. Start by removing any dead branches and then move on to branches causing structural problems. A portion of the older wood is removed each year over a 3 year period. Older wood is often the taller branches and may contain insect or disease problems too.
