Growing hibiscus is not an arduous task. The occasional gardener can grow hardy hibiscus with good success by following a few simple suggestions. The first task for growing hibiscus is to select an appropriate site. The plant site should have adequate sunlight. The sunlight should be fully available for at least 6 to 8 hours a day.
The second growing condition that needs to be addressed is the soil. Hibiscuses are quite adaptable to soil types. Providing a location with highly organic soil will greatly enhance growth and flower production. To increase organic matter, it may be advisable to mix sphagnum peat moss into the planting soil. After planting, the soil needs to be kept moist constantly for the first year or two. When they are fully established, they can accommodate some drought or excessive moisture.
Plant protection in harsh climates, zones 4 through 8, is also an issue for growing hibiscus. Providing mulch during winter is imperative. Pile the mulch up to 12 inches deep to keep the ground from freezing around the root system. In zone 8, the mulch does not need to be as thick as in zone 4.
Hardy hibiscus plants are not as prone to insect or disease problems. They may have occasional outbreaks of spider mites and Japanese beetles. Controls for these pests may be purchased at the local garden center. Growing hibiscus is a task that is very rewarding, especially when the first filmy, light bloom presents itself in your garden.
