Help My Mandevilla Vine Survive The Winter!

I’ve tried to winter over mandevilla vines…and usually they die by mid-January. This year, I had a beautifulone (large red blossoms). I put the plant inside in early October, and cut it back. It dropped all ofits leaves by the end of December, and appeared to go dormant (so far so good). Now, (mid -February) ,it is putting out leaves! What should I do? It is about two months till I can move the plant outside again…I’m afraid I’m going to lose this one too!
What should I do? :rolleyes:
