Long time reader, first time poster! I'm looking for some advice for when would be the best time to overseed and with what type of seed. I plan to aerate before I overseed, the soil isn't awesome and it's compacted (red clay). I'm in Western Virginia and the lawn was sod (newly constructed house) put down in early Spring. It has some thin sections but is mostly full. Some of the yellow spots in the picture below are from our dogs using the bathroom and I'm not concerned about that unless someone has a magic solution. We've had an extremely dry spring/summer but I've been trying to keep it watered at least once a week since it was put down (more frequent the first couple months).
