Choose an area with full sun, then amend the soil as needed and add compost. Plant a well-established swamp hibiscus directly in the garden, or start the plant from seed. If sowing the hibiscus from seed, soak the seeds in warm water for an hour, then plant the seeds directly in the soil. If possible, plant swamp hibiscus plants near a water feature, such as a pond or fountain, to ensure the plant has enough water to thrive.
The soil around the plant should be wet during spring and summer to encourage aggressive blooming. Water the plant daily if the soil appears dry.
Add compost to the soil at the beginning of the growing season. Add a thick layer of mulch around the base of plant at the beginning of winter.
