Need advice on what to do for my troubled lawn. The ground around our house is basic red clay. On top of that we have spread a layer of brown top soil that was taken from a low spot in a field by the house were hoping for a pond some day if it will finish filling. Anyway, I think this is dirt that has washed down into the low spot over the years. It looks like pretty decent dirt, but the grass hasnt been all that happy with it. We sowed a fairly heavy application of Rebel III fescue late Spring 2004; plug aerated and over-seeded Spring 2005 and have been rewarded with a less than spectacular stand; millions of cuckle-burrs however. I had the cuckle-burrs sprayed last Fall, additionally we spread lime (1 ton / acre) and fertilized with triple 19 from the Co-Op. I had intended to over-seed agasin last Fall, but with the lack of rain decided to wait until early Spring this year. What else would you guys suggest? BTW, the yard is about 4 acres.
