Cheryl, I just re-read your post, you are concerned about the bananas reproducing as you won't be able to monitor 100%. One thing about banana trees: once the fruit is cut from the tree, the mother dies and kind of just melts away.
There will be pups, but they could easily be cut/thinned out. And if you decide to transplant pups, plant them about 10 feet away from each other to give them room to grow as their leaves could get quite large. And if you keep transplanting new pups, then you'll have a plantation.
