will my pumpkins ripen
I have 3 large butternut pumpkins still on the vine and still green. If I cut the stem a meter from pumpkin will they ripen, or do they need to stay attached?
Did you plant these from your own harvested seeds, or did this come from a seed packet? It doesn't look like this particular variety will ever turn any other color, even if left on the vine. It appears to have cross pollinated with another member of the same family. This is common to have something come up that looks nothing like the parent if it were a seed from an openly pollinated plant.
