I haven't been here all that long either, but the consensus seems to be either keep the plant actively growing if you have a warm and sunny spot inside, or dig them up, remove most or all of the leaves, and store in a dry, cool (no freezing temperatures), and totally dark place. The roots are very prone to rot, so must be kept just barely alive (I'd personally endorse packing in a large container of peat moss, check occasionally for problems)until the spring. It tends to be a hit or miss thing with most growers, some apparently having hit upon the right combination of variables. If wintering over inside, minimum water is the rule, and watching closely for tag along spider mites, white flies and the like. You have to "think like the plant" and give it what it needs to survive the conditions you create for it when you take it out of the jungle. Not an easy task for many members here, but we tend to be on the ditch side of mainstream, and enjoying pushing the envelope. Lots of luck with your bananas over the winter, whichever method you chose.
