Hibiscus can be kept indoors in pots through the winter months. Indirect light should be provided until the blooming season begins in early spring. When no danger of frost is anticipated, the potted hibiscus can be brought outdoors. However, abrupt changes in environment could shock the plant and stunt new growth. To ease acclimation, direct exposure to sunlight should be minimal for the first few days and increased in gradual increments over 10 to 14 days. - Hibiscus kept in pots may never get taller than 4 or 5 feet, but in the landscape they can reach heights of 12 feet. Direct sunlight is inevitable with a plant this size, and any partial shade provided by nearby structures or trees can be beneficial. Long summer days of constant direct sunlight may be too much at times, but a healthy landscape plant can rebound nicely after dusk. Regular light watering helps prevent any serious stress.
- Carefully cultivated and pampered hybrids that are accustomed to a climate-controlled environment may never make a successful transition to the landscape. Ribbon-winning show plants and hybrid hibiscus are treated to indirect and sometimes filtered light. The humidity and temperatures are kept at optimum levels for the varieties being grown. Cuttings that are started in a greenhouse can be moved outside in their first few months, anytime from spring to fall.
- Pot-bound hibiscus plants are known to bloom more profusely than landscape plants and can be brought indoors to avoid a frost. Small gardens or patios can be brightly accented or provided with a centerpiece. In warm climates, hibiscus can be used for a hedge or planted at a corner to soften a structure's appearance. Moderate amounts of direct sunlight and regular, light irrigation is rewarded by bright, vivid blooms and a rapid growth rate.
