My dwarf gardenias were full and beautiful. Last winter it went down to 7 degrees for about 3 days. I live in Georgia and that never happens here. I didn't think the gardenias would make it since all the leaves died so I just left them alone to see what would happen. They have leaves all over them now but they are not full any more and all the tips are dead. I'm slowly trimming that off. Should I cut the bushes way back this fall? I don't know what to do with them now. I would appreciate any help. I attached 2 pics but not sure if they're showing up or not
