Hibiscus includes up to 300 species of plants that encompass trees, shrubs, perennials and annuals. The subtropical plant cannot tolerate large fluctuations in temperature and grows best when the thermometer stays between 65 degrees Fahrenheit to 75 degrees F. According to the University of Minnesota extension service, the hibiscus can be grown indoors during the winter months. Temperatures below 55 degrees F. will cause blooms not to open or flower buds not to form. Locations for the indoor winter planting should have full sunlight and be well away from any temperature extremes such as heating radiators.
Mix a hibiscus potting soil that contains two parts potting soil, two parts peat moss and one part perlite or vermiculite. Fill the pot half way full of the soil mixture.
Choose a pot that will cause the hibiscus plant to become root bound. According to the North Dakota Extension service, placing a hibiscus plant in a pot too large will not cause it to bloom, as the plant must be slightly root bound to produce flowers.
Set the hibiscus plant into the pot. Keep the soil equal to within 1 inch below the top lip of the pot. Backfill the potting soil mixture in and around the roots. Gently tamp the soil down with your hands.
Water the hibiscus plant well with water. Allow the water to drain from the pot several times. The repeated watering will remove air from around the roots, and improve the root-to-soil contact.
Fertilize the hibiscus plant with a ½ dilution of the 10-10-10 fertilizer. Follow the label directions. Hibiscus plants do not enjoy over fertilization. Add fertilizer at ½ strength every month during the winter.
