Hello Big Tony,
Thanks for your comment which I understood very well.
I live in a coast side of central Japan by the Pacific ocean, of which climate
zone, I believe is about 9B.
I grow almost all bananas in a 60liter(abt16gal) container, and I give liquid
frtilizer of 5
5 almost every weeks and I see this works well to ther bananas except Calif. Gold.
This, in fact, is the fundamental reason why I started to wonder if this banana
could be unprolific.
