Joe,
I have that problem with getting grass to grow and so do four other houses on this block. When I first built my house I tried everything to get a good lawn and about the time the grass would get high enough to start thinking about mowing it, it would turn brown and all die. I even had a couple of the nurseries come out and take soil samples. Then I had the whole top 8 inches scraped of and new supposedly good dirt hauled in and spread and it is the same. So I quit trying and just have two yards full of dust now. A couple of the neighbors had gravel hauled in and covered theirs with that.
