The Short Answer

Grass Seed (Lawn) can be planted based on your local frost dates. Use our homepage tool for dates personalized to your zip code.

How to Grow Grass Seed (Lawn)

Grass seed timing depends entirely on grass type: cool-season grasses (fescue, bluegrass, ryegrass) germinate best in fall when soil is warm and air is cooling; warm-season grasses (Bermuda, zoysia, buffalo) need late spring when soil temperatures reach 65°F+. Fall seeding of cool-season grass is so much more successful than spring seeding that many turf professionals refuse to do spring installations. Soil contact is critical — rake seed into loosened soil, don't just scatter on top. Keep seedbed consistently moist (multiple light waterings daily) until grass is 2 inches tall.

Direct Sowing

Grass Seed (Lawn) can be direct sown 2 weeks before your last frost date. Plant seeds 0.25" deep.

Growing Tips

Cool-season grasses (fescue, bluegrass, rye): plant in early fall or early spring. Warm-season grasses (Bermuda, zoysia): plant in late spring after soil warms to 65°F+.
