I purchased this last fall and have gotten it through it's dry period apparently successfully. I don't know when I should repot it so it is in a fresh medium and what it needs in the summer. It is putting out a new growth and there are some indication of some growth on the old canes, maybe flowers? It is in a 2" net pot lined with coconut fiber, I can't determine what it is actually potted in but it doesn't seem good. This is the first I have grown so small a plant and needing a dry spell. I don't know how to treat it to keep it alive, suggestions please.
