As of late I have had more luck raising a great stand of weeds than anything else w/this "go to he%$" drought we're having. It really doesn't matter what pre or post you use because in my mind of one doesn't irrigate you're screwed where fescue is concerned. Could it be that climates have shifted to a point that one would be wasting his time bothering by planting fescue in this climate? I have a pretty big yard and am to the point of inviting zoysia or centipede in my yard. However, I'll never allow wire grass a moments peace.
