I'm in Wisconsin and have overwintered my bananas in containers for the last 3 winters. I have a basement I put most of them in, also about 50 - 55 degrees F. I have lights set up on timers that give about 14 hrs. of light. I only water enough to keep them from drying out. The basjoo continues to grow, and some of the others also may put a leaf or two out during the 7 - 8 months they are down there. I have a screen porch with clear panels that I may bring some of them up when I get some warm days, but most are down in the basement the full time. When they do get back outside, they do get some leaf burn and look a little rough for a while, but they come back quickly when the warm days finally hit. I also have palms, and some other tropicals that get the same treatment, and really don't lose too many. I do keep some upstairs in the few sunny windows I have, mostly the smaller plants because they need better care.
