Answer: If your hibiscus is the houseplant type (basically a tropical plant), then they can't be left outdoors all winter long. You can place them, pot and all, outside in a month or so after the last frost date (early May), for the summer and they'll grow fine. Just bring them in this fall. Keep them well watered, fertilized and in a location with at least 4-6 hours of sun a day.
