I have 2 lovely gardenia bushes outdoors and wonder when is the right time to prune them and how much. Last winter was a hard one for us here in Ooltewah, TN (Chattanooga area) and I thought I had completely lost them, they looked really dead this Spring but they came back and have been covered with blooms.
I think I should cut them back but don't know when or how much.
Thank you for any advice you can give me
