Your banana tree is beautiful. You can buy tiny bananas plants in Germany too, to keep them as a nice tropical accessoir in your house. No chance to grow them outside.This is a stand of banana trees that i keep growing in a large plastic nursery tub, i think it is about a 65-70 gallons. Started from a little pup thst i ordered from a guy in north or south carolina i think. Anyhow....i water and fertilize all summer long, but unfortunately have to cut them back and drag the entire thing into our garage in the Fall to keep them from freezing. A process, just like everything.
