Hibiscus Care
The care you provide your hibiscus will vary depending on whether it is a hardy or tropical variety and whether it is grown indoors or outdoors.
Types of Hibiscus
There are hundreds of tropical and hardy hibiscus hybrids and cultivars available. Just a few popular varieties include:
Pruning
Hardy hibiscus benefit from annual winter pruning once they are established. Cutting the plant back after flowering, especially dead, damaged, and diseased branches and old wood growing in the center of the plant can aid air circulation and keep the plant looking tidy. Don't worry if you cut back aggressively; this species can handle it.
Propagating Hibiscus
Most hibiscus propagation is from cuttings. Select a four- to six-inch piece stem from new, vigorous growth. Keep the leaves at the top of the stem but remove all the rest. You might want to dip the cut end in rooting hormone before potting in a well-drained, moist potting soil. It can take a couple of months for the root system to fully develop.

Nutrient-loving potted hibiscus will benefit from being repotted every couple of years in early spring. Avoid deep pots, otherwise the plant will spend a lot of its energy on root development, and you want it to focus on flower production.
Common Pests
Hibiscus are not bothered by many pests or diseases, but red spider mites can be problematic when humidity levels are not high enough. Aphids are sometimes an issue too, but they can be kept at bay with regular cleaning or insecticidal soaps.
