As for the alocasia, here’s a previous how-to from the forums: https://awaytogarden.com/forum/viewtopic.php?f=17&t=272 As for the Allamanda, I don’t have enough light and warmth to keep it happy and active all winter, so I’d cut it back maybe halfway, and withhold water (not letting it dry for weeks, but not watering until dry, either) to force dormancy. No food, occasional watering, just keeping it alive but not active. I don’t know the ideal temperature, but I’d think not too warm, but not extreme cold, either. I’d probably put it in my mudroom or somewhere 50ish. Caveat emptor: haven’t overwintered one in the house here, but that’s what I do with tropical things I cannot keep active and happy…force dormancy or near-dormancy all winter.
