It is surprising it is even alive. It takes weeks for cuttings to root, not days. Usually they are kept in the shade under glass or plastic since they can't take up moisture until they form roots. That fact it is still alive is amazing. I would shade it with something like a cedar shingle for a year before I did anything with it since it sounds like it is living on borrowed time. Rhodies move easily when they are healthy, but when marginally existing, the slightest mishap could be fatal. This winter it will need protection from winter sun and winter wind.
