John, banana plants tend not to produce when they are potted although I have seen some that have. If you are trying to find a plant that produces edible fruit I wouldn't be looking for seeds, but rather live Tissue cultured plants or divisions.

Banana plants enjoy any type of fertilizer especially those with high N when they are actively growing during summer. I fertilize all my plants with 20-20-20, fish emulsion and lawn fertilizer in the solid pellet form (its cheap). hope this helps

many thanks banana_fun for your informations.

Unfortunally in Greek market I can't found live Tissue cultured plants or divisions or seeds, so I must to import those from Europe.
thanks

John
