Re: Musa Dajiao
I am thinking of leaving it outside unprotected.
Last year I lost all my bananas because we had some cold weather from north east Europe in spring that lasted for a week, otherwise all the banana did well in the winter including the small one.
We rarely reach -2 and usually for few nights only.
Instead last spring we had a snow with -1 during the day and -2/-3 during the night for a week, at the 3rd day all nana died because of the water inside freezing and cracking everything. Some were even protected with pluriball.
They were all smaller than this however.
