"Musa Basjo " banana tree

I have about 10 Banana trees , which are winter hardy and grown in 5ltr air pots ( not included) .
The pots open up at the side and the tree pops out as a large rootball .
I can also put the tree in a biodegradable bags which can be planted straight as they are into the ground or containers.
The trees do produce fruit but the at Not edible..
The tree can grow up to 2mtrs tall and they also produce side shoots of new plants which can be divided off .
They are 1mtr tall now .
If planting outdoors , the leaves will die back with the first frost.
To protect the tree , cut the main stem about 10cm below where the leaf meets the stem , put a small yoghurt pot up side down to stop rain going down & rotting Then wrap the stem with garden fleece.
In the spring , the plant will start going again from where it was cut .
