Winter Care for in Ground Hibiscus
I have hibiscus plants in containers that I bring indoors for winter. But I have one in the ground, is it ok to cover it with a garbage bag to protect it from freezing temperature?

If it is a hardy hibiscus, it will not need any protection. If it is a tropical hibiscus, than if you are in an area where the temperature gets below 20F, it will not survive, regardless of the protection you give it.
