I have two DCs with bunches hanging, both still green. The first bunch appeared in early August. Some of the fruits are starting to crack now, and temperatures here should be relatively cool for the next few months, so I'm afraid they will just go to waste hanging on the plant. I tried covering with a plastic bag, but that only seemed to rot the tips of some of the fingers.

Would I be able to cut this bunch and hang it indoors, or do I need to wait for at least one to turn yellow? The bananas seem to be filled out, but still very hard and green. (Sorry, I'll try to get pictures up later)

Thanks
