I have a banana plant, which I would like advise on how to seperate please?

Hi, this isn't advice from experience it is from a book I have, hope it may be helpful:

"Banana's produce offsets or suckers which can be removed, the offsets should be potted singly and keep at 21oc until established, new plants may need sheltering from wind."

Technique:
1) Cear soil away to expose sucker's point of origin. Use a large sharp knife to cut downwards and detach the sucker with as many roots as possible.

2) Fill in soil around parent plant. Dust cut surface (of sucker) with a fungicide. Remove any lareg or damaged leaves from sucker to prevent water loss. Pot into a container just a little larger than root stock, at the same depth as before. Label, water and grow on in warm shaded place.

Good luck with your Banana.
