I have had my tropical hibiscus for about 5 years. It lives outside all summer, and I bring it into the basement for the winter and water it sparingly. Once outside for the warm weather it does very well and
flowers continuously. It is getting very big and although we prune it before bringing it inside we wonder if it is too big for its pot (which is quite large). Can the hibiscus be divided/split, will it benefit from this? I don't want to kill the plant as it is quite nice and does well but I am not sure what is the best way to care for it. We don't want to place it in a larger pot. Thanks for any advice!
