I was told by my father-in-law to flip my pumpkins so that they would get even color/shape. When I did this to my largest pumpkin (30-40 lbs) there was no problem until the next morning when I found that it had totally broken off the vine. The rind on the pumpkin is still soft, and I am wondering if there is anything I can do to mature the pumpkin so that I can still use it for Halloween. Or, if there is no way to save it until then, is it edible? Or should I just compost it? Right now I have it sitting on my deck (on a cushioned chair) with the white/flat side facing out so it gets the most sun. Any advice would be helpful!
