I have two gardenia bushes that were probably planted when the house was built, so they may be 14 years or so. They were both huge. One blew over in a storm; I replanted it, and when it was still not doing well, I pruned it back, hard. It has come back but is much smaller than it's huge mate, and so they both look awful. I'm thinking of trying to prune the huge one way back but wonder if it's worth it, and would it even survive a hard pruning. At what point do you decide to just dig up the plants and get new ones? I HAVE to have gardenias, I love them!
