I have a Gardenia growing in a pot on my deck with partial shade. I have been noticing brown spots on the leaves, which are a brilliant green color, and it has only had two blooms and hundreds ob buds. They bloom one at a time after the previous bloom dies. I have not had a plant do this. It also has dropped a few mature ready to open buds. I haven't seen any signs of insects and I try to water without getting the leaves wet. I need some help the blooms smell so wonderful it would be nice to have more than one. Thanks for any help.
