Grass Seed

When to Plant Grass Seed

Fall is best for planting cool-season grasses like Kentucky bluegrass, perennial ryegrasses, and tall fescues. Daytime air temperatures should be averaging between 60 and 85 degrees which translates to soil temperatures between 50 to 75 degrees. Spring is the second best option for cool-season grasses. Warm-season grasses, like Bermudagrass, Bahiagrass, Centipede grass, and Zoysia grass have the most successful germination rates in spring and early summer when daytime temperatures average about 80 degrees.

How to Plant Grass Seed

Test to be sure your lawn pH is between 6.0 and 7.4. Prepare the seedbed and broadcast your seed at the recommended rate. Keep it constantly moist by watering 2 to 3 times per day with a mist spray until germination. 

How to Water Grass Seed

Water newly spread seed by lightly spraying 2 to 3 times per day. The goal is to keep the soil moist, but not wet. Once your grass has germinated begin to water heavier, but less often.

When to Overseed?

Late summer into fall and spring are good times to overseed northern yards with cool-season grasses. Southern lawns should be overseeded in the fall with cool-season grass.

How Long for Grass Seed to Germinate

Germination time varies amongst different types of grasses. Even the same seed will germinate at varying rates within different climates. Expect your grass to emerge within 7 to 21 days.
