My Indoor Plumeria Is Going Into Dormancy. May Put It In A Dark Room Until Spring?

Question

I have what I call a sun room, where I put my outdoor plants for the winter.

Answer 1

I bring mine inside once overnight temps get close to 50F and leave it there until overnight lows are above 50F in spring. Stop watering, misting, fertilizing, etc. once it loses all foliage. Resume watering when you see leaf out and place it near a southern facing window. Sun/dark rooms may be fine if temps remain warm or above 40F.
