question about hibiscus

I live in Houston, Texas. I have several types of hibiscus in the ground. My question is, when it is fixing to freeze, do I need to cover these or just let them go? They are facing the north wind.

This depends on the species of hibiscus you have. Hibiscus are generally divided into hardy and tropical varieties- hardy hibiscus will not mind a freeze, and can be kept outdoors without protection in USDA gardening zones 4 and above.

Tropical hibiscus plants are usually brought indoors in cooler regions, but many varieties can survive in zones 8 and 9 with protection. Parts of Houston are in zones 8b and 9a. Here is some advice on covering plants:
