Every year we add more pumpkins. They will be ready in late September through October. It is hard to say which the kids enjoy most: the wagon ride to the patch, or the search for the perfect pumpkin to pick.
We try to have some pumpkins up near the store, but they often don't last long. These were snowed on shortly after Halloween.
Some past pumpkins carved by a professional. Of course, you might be able to do better! And yours will certainly be unique.
