  1. 1

    Select a site for your hardy hibiscus plants that give it full sun or a light shade. Grow your plants in nutrient-rich soil for best results.

  2. 2

    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.

  3. 3

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

  4. 4

    Put your hardy hibiscus in a pot rather than in the ground if you prefer. It makes a good container plant. Ensure that you water frequently to keep the soil moist.

  5. 5

    Realise that the hardy hibiscus dies to the ground annually and grows back the next year from the roots. Avoid digging up a live plant before it has a chance to emerge in the new growing season.

  6. 6

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

Tips and warnings

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