General Growing Conditions
-
All types of hibiscus require full sun and soil that drains well. Except for the Rose of Sharon, which is frost tolerant, hibiscus plants will die back with the first fall frost. In mild winter areas, you can expect your hibiscus to come back from the roots in spring, but where the soil freezes, you can grow it as an annual that you replant each spring.
Indoor Growing Conditions
-
Plant your hibiscus in standard potting soil in a pot at least 12 inches in diameter. If you keep it on a plant saucer to protect your carpet or furniture, empty it after you water to prevent the roots from rotting. Before you water again, allow the soil to dry. Keep your plant near a sunny window or provide fluorescent light, especially during winter.

Fertilize for Optimum Blooming
-
Give your hibiscus fertilizer every week between March and October. Use a plant food with an N-P-K ratio of 20-5-20 to encourage healthy leaves and prolific blooming. Check the composition of your fertilizer and choose a brand that contains trace elements such as iron and magnesium.
