Growing pumpkins in old leaf pile?

I work at a gravel pit that used to take in leaves from the city but hasnt in about 10 years. The leaf pile is roughly 15 ft T x 80 ft W x 15 ft D. I havent dug into it but Im guessing its turned into some good soil by now. I dont really want to make a mess of the pile so I was wondering if I could plant pumpkins directly into the pile if they would grow? I thought it would be cool to plant the seeds at the top and let the vines run down and produce the pumpkins.

Thank You for any advice.

Yes, and I bet that those pumpkins will be very happy and produce lots of fruit.

Under that pile, the stuff that looks like soil is what is called leaf mold and one of my favorite kinds of amendments.

What a lucky find.

Planting the seed directly into the pile will not hurt the seeds.

I like the idea of planting the seed at the top and letting the vines run down and produce the pumpkins.

Please let the forum know how this works out for you!
