We got a gardenia for Mother's Day, and it looked great. Then I put it outside for a couple of days, and it began looking awful--limp and droopy. Anyway, I figured out how to bring it back to life, and it looks a whole lot better now. The stems seem nice and firm again. However, some of the leaves, even though they're standing up, look crisp, shriveled, and dried. Is it best to just remove these or what? Thanks for any info.
