Re: How big should my container be?
You haven't mentioned what type of banana you're trying to get to fruit. The dwarf or smaller ( such as a Super Dwarf Cavendish) would be the best choices. I'm trying to get an SDC to flower now in an approximately 25 gallon container that was actually meant to hold ice around a keg of beer that I added some drainage holes around the botton of. It's stronger plastic than the usual trade pot and can be moved easily with a hand truck. In any case the largest container you can manage would be best to allow for the most root development.
