Overseeding uses less seed than a new lawn because you are filling gaps. Pick your grass and lawn condition for a realistic amount.
How it works
Lawn area ÷ 1,000 × a typical overseeding rate for your grass, with a higher rate for thin lawns.
Before you order
- Mow short and rake or dethatch first so seed reaches soil.
- Fall suits cool-season grasses best, once the summer heat breaks.
- Keep the top layer of soil moist until seedlings reach mowing height.
Common questions
Can I just throw seed on my lawn?
Seed lying on thatch dries out and rarely takes. Loosen the soil or core aerate first.
How much seed do I need per 1,000 square feet?
Common rates are about 4 to 6 lb for tall fescue and 4 to 8 lb for perennial ryegrass, with Kentucky bluegrass much lighter at about 1 to 2 lb.
