Hi again Chris! Just did a quick re-read, and realized I forgot a couple of comments. Repot if you want, but don't fertilize or water other than to maintain growth as you did last year. If your garage is not heated, you might think about placing your potted banana inside a second, much larger pot, filled with peat moss or similar insulating material to protect the roots and p-stem (primary) from cold and damp. I'm guessing that whatever you did last year can be repeated, since the results were positive.
