Ok, so this guy had 3 large oaks removed from his front yard. Stumps ground up. Most of the roots removed. But the soil is still very oak chippy. I was told these oak chips are very acidic and you will never get a lawn to grow on top of that. If the yard was regraded, and topsoil put down wouldn't this be sufficient? The home owner wanted a whole half foot of soil removed from his entire stump tree area and start with fresh topsoil. Could the lawn been seeded with out removing a half foot of soil ? Would lime help the oaks acidity? Please Help .... Thanks!
