Hi everyone I haven't been on for a bit so I am a little behind. I have been busy with the kids going back to school and work starting back up for me. But I wanted to answer this because I've had the same Red mandevilla for a few years. I bring it in my heated garage. It stays cooler than the rest of the house and doesn't get dry like in the house. It only gets late morning sun through some square windows on the door. The Mandevilla usually turns yellow and dry and a lot of the leaves fall off, then it seems dormant so don't think it's dead and only water it occasionally. I am pretty sure too much water in the winter will kill it. Mine is in terra cotta which is probably good too. My aunt has also kept one through the winter in her very sunny porch, it is heated as much as her house, but I think it is so sunny it keeps her heat from coming on, on sunny days. However I think they are adaptable but they don't look very pretty in winter so I wouldn't really consider it a house plant. Hers does flower a lot longer than mine after it comes in. In spring when we have days in the high 60's I start bringing t out for a little while to get it used to the sun again.
