That's 40.0 lbs at 8 lbs / 1,000 sq ft for a new lawn.

  • Best window: cool-season grass in early fall (Aug–Oct), warm-season in late spring (May–Jun).
  • Water 2–3× daily for the first 2 weeks — keep top ¼" of soil moist until germination.
  • Skip mowing until grass hits 3–4" — first mow at 2.5".

Frequently asked questions

How much grass seed do I need per 1,000 sq ft?

Tall fescue: 8 lbs new / 4 lbs overseed. Kentucky bluegrass: 2.5 / 1.25. Perennial rye: 6 / 3. Bermuda and zoysia: 2 / 1. Sun-shade mix: 5 / 2.5.

New lawn vs. overseed — what's the difference?

New (bare soil) seeding uses 2× the seed rate. Overseeding a thin existing lawn uses half. Always match the rate to what you're doing — under-seeding gives weeds a foothold.

Best time to seed a lawn?

Cool-season grasses (fescue, ryegrass, bluegrass): late August to mid-October. Warm-season (Bermuda, zoysia): late spring after soil hits 70°F.

Do I need starter fertilizer?

Yes for new lawns — starter fertilizer is high-phosphorus for root development. Skip nitrogen-heavy fertilizers until 8 weeks after germination.

How long until I can walk on it?

Light foot traffic at 4 weeks. First mow at 3–4 inches tall. Full use around 8–10 weeks. Avoid pets and heavy equipment until then.
