Back in early July I had my soil tested. I tested both sides of my lawn and the front. The right side came back with a PH of 5.7, front was 5.1, and the other side was 4.2. Right after I got the results I put down 100 pounds of lime(my lawn is roughly 1500 square feet). The recommendation was 50/lbs per 1000 square feet. Early in september I had my lawn aerated and I put down another 100 pounds of lime. I wanted to get the lime down into the soil. I then seeded and fertilized(I used Espoma Organic) at the recommended rate. I topdressed with Black Cow Composted manure. The seed germinated within 4-5 days and was doing fine, but now it appears in some sections(mainly the top of the front lawn) the grass growth is stunted. This area does get a lot of sun and it has been consistently in the 80's, but I've been watering a lot. Any idea what it could be. I overseeded with Pennington's Plantation fescue. PS - The soils here are a heavy red clay and I've been told you can't put too much lime down. I also have one of the soil probes and if it's accurate, my PH is around 6.7-6.8. Thanks if advance for your responses.
