question about hibiscus

Question

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.

Answer 1

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:
