I brought a potted mandevilla into the house, trying to keep it alive through the winter. I think that I'm doing all of the right things, and it has new growth, but many of the leaves are turning yellow and dropping.
Does anyone have any ideas? Maybe it's adjusting to being moved? I realized this morning that there is a heater vent near it, so with the furnace turned on the last few days, I closed that vent so it won't get too warm.
Has anyone else had success with a mandevilla through the winter?
