I need to prune the following plants, please advise when is the best time/season to prune them:
1. Mt. Laurel
3. Upright and spreading yews.
Also, how far can I cut back the Holly and yews? I need to cut them back as far as possible.
I live in CT, and due to the damaging blizzard last fall I did not trim anything very much. Thank you very much.
