Re: Banana seed germination after 5 cold nights!
also it was a cycle between night and day, near 0°C overnight and so between 20° and 25°C overday. I do remember about germinating Parajubaea torallyi from the Andes from Peru. Musa sikkimensis is a mountain banana from the Himalaya.
Helton has also protected the seed from cold, fortunately no frosts. He also was surprised.
