Answer: You sound like a patient gardener, which is a true boon for your little trees! Actually, you can prune plum trees after they have finished blooming. European plums should be pruned to a central leader or modified central leader, and Japanese plums do better with an open center. It's best to have illustrations/diagrams to follow when pruning. I haven't been able to locate any really helpful diagrams on the internet, but a good fruit tree book will show you the ropes. Go to the library and photocopy the diagrams you need, or contact your county agricultural extension service (ph# 704-792-0439) -- they should have an illustrated bulletin for you. Enjoy!
