Throw seed out over the lawn- 15% germination<br>New lawn, tilled & levelled - 85-90% germ<br>Slit seeding after aeration - 65-75%<br>Basic slit seeding - - 60-65%<br>Seeding after powerraking - 20-25% germ<p>Success with grass seeding is basically seed to soil contact. Seed should ideally be planted 1/32" to 1/16" deep. Powerrake or dethatch doesn't lift up much soil to accept the seed. Aeration alone, then seeding, is better than powerrake and seeding from my experience.<p>----------<br>Jim<br>North central Indiana
