We excavated for a new patio in the spring and have a large berm of
relocated topsoil that's just right for a pumpkin patch next year.

The berm is totally covered in a very common weed here in NC - looks
like bamboo/grass, easy to pull, grows 2ft tall or so. Just mowed it
down, but was wondering if I could kill the weed seeds by covering it
now w/ black plastic until next May.

Have ordered Dills Atlantic Giant pumpkin seeds - anyone have any
experience in nc growing these? Should I ammend soil now in
preparation for next year? thx!
