I have a hibiscus that I have pruned like a topiary tree. We moved it and staked it. It stressed for a while and then looked great with lots of pink blooms. I forget the name but the flowers are double and they look somewhat like a carnation. The leaves keep falling and now the only leaves that are left are just on the tips. It is still flowering, poor thing. I don't know what to do with it. It gets morning sun and then late afternoon sun. It rains a lot here but we have hit a dry period so I water it a couple times a week and I fertilized it a month ago. What am I doing wrong?
