Pruning Evergreen Shrubs
Many evergreen shrubs will require regular pruning or trimming each year. Most can be pruned around mid-June, after some new growth has developed. Check each variety for best timing. Pyramidal junipers will need trimming to maintain the pyramidal form. Spreading junipers may need trimming to prevent them from spreading into other plants. Plants such as Fairview Yews are spreading, but can be shaped into globes or hedges. With an evergreen shrub, you never want to prune into old wood. It is best to trim just a few inches of new growth each year. Don’t wait several years to trim and then, try to reduce the shrub by several feet. Plants will not fill in nicely to cover the old wood.
