Should I prune my gardenia bushes?
I have 3 large gardenia bushes around my deck in the backyard that have grown at least 18" since last spring. They seem to be healthy and I can see a few tiny flower buds forming already this season. These bushes are very tall (about 4') and I'm not sure how big I'm supposed to let them get. Should I prune them back after they bloom in June? If so, how much?
