Air layering question
I have an 8 ft plumaria that is just too tall to bring in. It was marginal last year. In mid to late July, I attempted to air layer about half way down the trunk. It hasn't rooted yet - I check it every few weeks. Now what? It'll be time to bring them inside in mid-October. Will it continue to try to root inside and while dormant? Should I leave it and continue to mist occasionally all winter? I can put it under lights but it will be so close it might burn. Uncover it and try next spring? Help! Anyone?
