This is my 2nd attempt at growing a hibiscus. The first one I planted outside. It died over the winter. This year I purchased one and decided to keep it in a container so I could bring it in whenever it froze outside. However, I guess I let it get too much sun. After blooming beautifully for several weeks it suddenly started dropping buds and leaves. What leaves were left curled and turned brown. It still has a few buds on it, but they haven't changed size in weeks. I took it out of the direct sunlight. It's now on a sunny porch. I keep watering it, but I'm not sure it's going to come back. How do I know it's too late to save it? If it's not too late, what can I do to help it along? Thanks for the help.
