Answer: Although hibiscus are sold in the low desert, as a tropical plant they are not ideally suited to our conditions, so our harsh environment can take a toll on them. Hibiscus prefer acid soil conditions, so use a good potting soil, mix in peat moss, and then fertilize with something like Miracid. As for keeping it humid, it's kind of a losing battle here. About the best you can do is group it with other container plants in a location protected from wind and afternoon sun.
