Instructions

    • 1

      Fill a small container with tepid water. Keep the hibiscus mutabilis seeds in the water overnight to encourage germination.

    • 2

      Fill the seed pots with a top-quality potting soil or a special seeding mix. Put one or two hibiscus mutabilis seeds in each pot and cover them with a thin layer of soil about 1/4 inch thick.

    • 3

      Place the pots in a location with bright sunlight and a temperature of 70 degrees Fahrenheit or more. Moisten the soil.

    • 4

      Water or mist the soil as needed to maintain moist soil. Watch for the hibiscus mutabilis seedlings to emerge in a week or more.

    • 5

      Thin to one hibiscus mutabilis in each pot when the seedlings reach 3 inches tall. Provide water when the soil dries slightly, but never let them sit in water.

    • 6

      Transplant the hibiscus mutabilis outside in the beginning of summer if you're planting them as annuals. Wait until the next summer to plant hibiscus mutabilis grown as perennials.
