damaclese;
I forgot to say that my area is not arrid like yours, (just the opposite) as a matter of fact, I have learned to plant on my highest ground or next ditches to promote drainage of standing water. Please know that I'm far from a Banana Guru, only a simple grasshopper. This is my second year of growing Bananas and it has been great. Lots of great folks on this Forum, and very helpful.
My observations have been that my best growth was in Sept. and Oct. as the temps started cooling off.
It could be that Bananas are kinda like us, I don't like the cold or extreme heat, he he.
