We have a green pumpkin in our garden. It stopped growing about two months ago. Should we pick it or leave it? Do you think it will turn orange? We also have a small orange pumpkin off the same vine but that one is not ripe. Can a pumpkin cross pollinate with squash? We have scalloped, yellow crooked neck, zucchini. We are confused.
