Justin, if you ain't moving, then adding on is your only option. I confess, I haven't moved in 25 years, and both kids grew up only knowing this one house. We did add on quite a bit, but the bananas are all outside, even so. I actually admire people spending the time and effort to grow a banana where it shouldn't ought to be. I was introduced to this insanity years ago when I saw a pix of a guy in St Louis with about 20+ banana pseudostems laid out on his lawn (most 8-10 feet tall) after dragging them out of his basement, and getting ready to plant them in the spring. I don't see myself being that devoted.
