Can Hibiscus Bushes Or Trees Be Planted In The Garden…
Carol Asked
Can hibiscus bushes or trees be planted in the garden or should they be left in containers to bring in the winter?
The Gardener’s Answer
Hello, Carol in Kentucky: The answer to your question depends on whether you are growing a tropical hibiscus or a hardy one. I am assuming you are referring to a tropical hibiscus, the ones you see in all the garden centers this time of year. They are available in tree form as well as shrubs. If this is the case, the answer is yes, it must come indoors during the winter months. It would not survive the winter temperatures we have here in Kentucky. Bring your plant indoors before the first frost and place it in a bright room with good filtered light. You can cut back on your watering as well as fertilizing at this time. You do not want the hibiscus to completely dry out but the soil should not be sopping wet either. Watering will depend on the temperature and humidity of your home. The light levels are lower during the winter months and the hibiscus will not likely bloom, but can successfully be over-wintered indoors and then taken back outside after the frost-free date passes in May. Hibiscus blooms best in full sun but when you take your tropical back outside after the winter, remember to gradually move it to a sunny location. It will need to be acclimated from being inside all winter long. If you are growing a hardy hibiscus (Hibiscus moscheutos) it can remain in the garden year-round. The main visual difference between a hardy hibiscus and a tropical one is that the hardy have flowers that are dinner plate in size.
