How to Care for New Grass Seed

By Lauren Wise ; Updated September 21, 2017

Seeding a new lawn takes preparation, care and patience, but the payoff is a luscious, green lawn. The key to remember after seeding a lawn is to protect the grass seed to make it strong enough to grow.

Use a rake to smooth over the grass seed on your lawn after the grass seed has been applied. The rake will help integrate the grass seed into the soil. Sprinkle a blanket of about 1/4 inch of peat moss over the grass seeds.

Use irrigation or a sprinkler to water the newly seeded lawn generously. For the first couple waterings, you want the water to penetrate the first 6 inches of soil. You don't want to create puddles, so you may have to break up the watering into increments. Water the lawn 2 to 3 times a day for the first 3 weeks, once in the morning, afternoon and evening.

Reduce the frequency of the watering gradually once you see the grass seeds sprouting. When your grass is fully grown, water it once a week generously to penetrate to the deep roots, but don't over water it.

Apply fertilizer about 5 to 6 weeks after germination, following the instructions for your type of grass and environment.

Let the grass grow until it is about 3 to 4 inches tall before using a lawn mower as you usually would. This will ensure that the grass is established.
