Grow your hardy hibiscus in the appropriate U.S. Department of Agriculture hardiness zone to ensure that your plant thrives. Hardiness zones are areas that have the proper climate conditions for a particular plant to flourish. The hardy hibiscus can do well in hardiness zones 4 to 10.

Grow hardy hibiscus in the moist soil it prefers. Make sure that the soil is well drained.

Prune the plant back 4 or 5 inches after the first frost.


The hardy hibiscus is one of the last perennials to emerge in the new season. It may not start new growth until late spring.
