I got a yellowing white wings hibiscus (they were going to throw it out) about a month ago that I wanted to try and bring back. I re-potted it into a larger pot and watered it, but the leaves kept yellowing and falling off. Ultimately I think I ended up over watering it, and the sticks/branches went brown and dry. I gave it up for lost and left it alone for about 3 weeks on the back porch without water. I went to dig it out today to use the pot for another plant, and discovered the roots still seem to be "damp". The sticks/branches are still dry though; is there any hope that this plant might come back, or is it gone for good?

Thanks!

As summerbreezes mentioned, add perlite to your soil medium. Perlite will easily drain water in seconds. But in the summer months you need to mulch your plant to lock in moisture. If you are using garden soil, your perlite should not be less than 20%. For me this is enough, but for some people they prefer 30% (70% soil medium + 30% perlite).

If your plant does not survive, graft its branches so you can grow it again. Check out Wally Morgan's website on grafting hibiscus.
