Alas, I cannot possibly grow these plants in either of my greenhouses. They are so jam-packed with plants, there is just no room. I do have two alternatives though.
I build a temporary, 6'x8' greenhouse in my garage just for overwintering plumeria, and there is a west-looking window that is at one end of the greenhouse. I could put a couple of plants in front of the window and keep them lightly watered. There is also the new sunroom that should be finished before fall. I could do the same thing there. The problem is that there is little or no possibility of moths getting into either structure. I would have to hand-pollinate and don't have a clue how to do that/when to do that. I wonder if those moths are around now and will do that job. I have several plants in bloom and more to come. I just don't know when the flowers are pollinated.
