There are very few organic controls for the bugs that like pumpkins. Unless you grow the smaller sized varieties, cooking a pumpkin is a chore now that the microwave oven has proven to be the most convenient method. Pumpkins have a short shelf life. To get them to last in fresh condition until the following April or May is just about impossible. Gardeners have bad backs.
Pumpkins make lousy pies.
Look at all the sugar and spice needed for taste. Worse yet, the pies always fall flat after removal from the oven. Butternuts have solid stems and are not attacked by the squash vine borer. Last summer, I harvested 79 butternuts from just two vines. I'm not bragging, but in the same space I could have gotten 4 large pumpkins or 12 small pumpkins.
