Hi , are you a UKOasis member ? if not then consider joining as there are some well informed Musa nuts based in the UK and other parts of Europe. There are UKOasis members here too , it seems that we only join the best forums :-) . Mark Hall in the UK sometimes has Musa for trade or sale.

I cannot help with Musa seed germination as I'm not good at it , but I will buy seedlings at a premium price from anyone with the germination skill ,lol .
Later
