Rates differ a lot by grass type. Pick your seed and job, and you will get pounds for your actual lawn.

How it works

Lawn area ÷ 1,000 × a typical seeding rate. Overseeding uses about half the new-lawn rate.

Before you order

  • Sow half in one direction and half across it for even coverage.
  • Cool-season grasses usually do best sown in early fall.
  • Keep the top layer of soil moist until seedlings establish.

Common questions

How much grass seed per 1,000 square feet?

About 6 to 8 pounds for tall fescue and 2 to 3 for Kentucky bluegrass on a new lawn.

Can I put down too much seed?

Yes. Crowded seedlings compete and can be more prone to disease.
