Does anyone have a suggestion for a Yard that is clay mixed with rock. Or maybe I should say rock mixed with clay. In the past I've used a slit seeder to reseed other yards but in this yard the rocks & yard size (2.5 acres) I think a slit seeder wouldn't work. So I am wondering if there is a seed I can use as a overseed that will take hold & grow in this poor soil. I'm in Jefferson County, Missouri.
