Answer: Unfortunately it is very difficult to maintain a rhododendron as a container plant under home conditions. They are very sensitive to drying soil or overly wet soil, as well as to build up of salts in the container. Also, you would need to figure out a way to overwinter it where it could undergo a chilling period -- but without freezing. Based on my experience, I would suggest you let it go. I'm sorry I can't be more encouraging.
