Hi Hal, Bgenerally we prune them in spring as the buds develop so we can see how far they have died back over the winter. You may want to check with your local Extension office for details for your area. please use this website to find the office nearest you. http://extension.psu.edu/Hort.html hope this helps. Sandy
