How to grow tropical hibiscus as a houseplant:Hibiscus rosa-sinensis needs fertile soil with very good drainage. Many gardeners suggest using a potting mix specifically for tropical plants and/or hibiscus. They thrive in sunny locations, so placing pots in south- or west-facing windows is ideal. You can also add fluorescent lights to help meet lighting needs. They do not tolerate temperatures below 50˚F. Keep them in a location with a constant temperature between 55 and 70˚F. Water sparingly during winter months—or when the top half-inch of soil feels dry. Make sure to discard any excess water that may have collected in the saucer. Feeding with a slow-release fertilizer may benefit the health of your plants. Pinch the growing tips in late winter and/or early spring to encourage more vigorous growth as well as spur more buds to appear and bloom.
