Bananas prefer a fairly loose soil. Properly grown, they will sucker profusely. The require about 15 months of warm weather to ripen fruit.

Except for some of the smaller types like superdwarf cavendish bananas won't do well in pots. No matter how big the pot. And you'd have to use a decent soil so that would be expensive. Some bananas sucker more than others. The ones in my front yard produce few suckers but the same banana in the backyard suckers like crazy. I think it's wetter in the back, shadier for sure.
Dig up the pups, trade them off, leave them in unlocked cars in parking lots-wait, that's zucchini isn't it?-ah, same principal.
Tally HO!
