How Do You Take Care of a Giant Hibiscus?

Care for a giant hibiscus by planting it in a good location, watering it properly, fertilizing it and pruning it regularly. This project takes under an hour for each step. You need water, compost, fertilizer and pruning shears.

  1. Plant it in a good location

    Plant the giant hibiscus in a location that receives full sun. It needs well-drained, fertile soil or a boggy area in which to grow. If you need richer soil, add compost or mulch. This plant thrives in soil with a high salinity.

  2. Water the plant thoroughly

    Because the giant hibiscus is native to the wetlands of Florida, it needs plenty of water. If it is not planted in a swampy area, give it at least 2 1/2 inches of water a week.

  3. Prune the plant

    Heavily prune the giant hibiscus in late winter, cutting the branches to within 1 foot of the ground. Leave the trimmed limbs on the ground around the plant, which protects the plant from water rot and frost. Trim off the buds of the plant before they blossom to encourage growth, and remove faded flowers.

  4. Fertilize the hibiscus

    Fertilize the hibiscus every year after the late-winter pruning. Use a fertilizer that is high in phosphorus and low in nitrogen so that only the flowers are stimulated into growth instead of the limbs and leaves.
