Ask the Expert: Pumpkin? Last year I threw old pumpkins that were not cut open in my back yard. I think they were just the small kind you use to cook with and they are hard to cut. Anyways now this year there is a big mysterious plant growing close to where the old pumpkins were. In the background you cant see it very well but the pumpkin is still there and has seed there still too.
