Yes! I just set them in the garden. Now there were some tilled areas where I had tried to grow something before, but patchy grassy areas too. Anyway, I did nothing else. Just set them there behind a small little wall.

They were just reclaimed and started growing on their own. I was really surprised because I don't have a lot of luck with growing things. But, maybe that will change. I don't know. I didn't weed or anything. It was really funny to look back there one day and see all of these pumpkins! The kids loved it!
We did start weeding and tending to them once we found them. I even threw some watermelon seeds back there in a different area and they grew too. So I guess those are two things that are easy to grow.
