Hellow,

I am living in a place of the lowest temperature is about

20F or -5C in February. Under this condition, Musa Sikki-

mensis, Velutina and Chinese Yellow overwintered without

any winter protections. I also have Helen's hybrid, Dwarf

Orinoco, Williams hybrid and they have not overwintered yet. So can anyone tell me from the actual experience how they could overwinter in a Zone like 9A?

I really want to know the experiences, but no theory.

Thanks in advance.
