Here is an old trick that will help stimulate germination of your grass seed. Place the seed in your freezer for about 4 to 5 days before sowing.

The freezing simulates the wintering over of seed and aids in cracking the hull of the seeds to permit moisture to enter and begin the germination process.

I first learned of this from my grandfather when i was a kid on the farm, but recently I read a report on the Ohio State University Agricultural Extension service that confirms it works.
