Not sure where you are located, or how cold it will get when. When light frost was coming here the first time or two last month, I covered things with a sheet for a night or two to get a little extra ripening time on the vine. But once the weather was inclined to a more serious cold spell, later last month, I harvested every fruit and put them all in a box together in my mud room. They have gradually ripened in the box (I put a couple of apples in, too, to help) and I’ve made them into soup and such. Unless they had really begun showing some orange-red color on the vine, at least a bit, they won’t ripen as nicely or tastily as outdoors, but they are good for cooking.
