Jamesdart,
I just finished digging all my banana plants up and potting them [just wish i hadn't waited till dark]. That included 2 red Absynnians [about 3 1/2 feet each], 3 Ice Creams, and 1 dwarf Cavendish. If you want them to be dormant [about 50-65*F] then you should prolly cut most of the leaves off and keep them in the dark. I read that light can cause them to come out of dormancy. I'm gonna leave mine warm [70-80*F] and not cut leaves off. One thing is certain, Absynnians get corm-rot very easy so I def wont water mine cept maybe a tiny bit once a month. Another thing is that Absynnians can get eaten fast by spider mites in the winter. If you think they might have mites, get them treated fast. And never put water or fertilizer directly on the corm. Anyway, it's def not a good idea to water or fertilize in the winter. Good luck and keep us posted on your progress!
