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.’

Step 12: Cut the grass with TLC
Mow the new lawn once it reaches a height of 3 in. Use a newly sharpened blade?it’s healthiest for the grass because it’ll make sharp, clean-slicing cuts. Cut just 1/2 in. per mowing. Always avoid using a dull blade?it rips the grass, setting up the conditions for disease.
