When were the seeds planted?

if it's just this summer then it's a bad time to do it since it's too hot during the day. The seeds have to be constantly moist to germinate.

Have you considered buying sod? It rolls out real frast.

Instant lawn.

Summer IS the perfect time to seed Bermuda. If you were trying to seed Rye it is s little early but with enough water would still get a good start. What seed was it?
