Step 9: Spread the seed
Load the seed into a spreader and apply it. Make sure it doesn't fly into nearby gardens. Turn the broom rake upside down and drag it side-to-side over the furrows until only 10 to 15 percent of the seed remains uncovered. To get good seed-to-soil , compact the soil with a rented sod roller filled halfway with water.

Step 10: Add mulch or grass seed accelerator
Step 11: Water, but not too much
Water the new lawn generously right after the mulch application, but stop as soon as you see puddles forming. One way to get even watering is to place an impact sprinkler in the corner of the lawn and set it to spray in a quarter arc. Then move it to the other corners. Keep the soil moist to a depth of 4 to 6 in. for best germination. Water regularly as the seedlings appear and grow. Gradually reduce the watering over a six-week period. Then switch to your normal watering routine.
'Most people overwater new seed. Just keep the soil damp for the best germination.'
