Grass grows fastest and strongest when your planting season aligns with the seeds' natural periods of active growth. Just as with other kinds of plants in your landscape, lawn grasses vary in their growth cycles and regional climate preferences.
Cool-season grasses like Kentucky bluegrass, ryegrass and tall fescue, grow most vigorously during the cool temperatures of late summer and early fall. These grasses flourish across cooler northern climates like New England.
Several distinct advantages make fall the best time to plant cool-season grass seed. In early autumn, the soil is still warm from months of summer sun. This combination of warm soil, moderate day temperatures and cool evenings encourages fast germination and establishment of newly sown cool-season grass seed.
Cool-season grass seed germinates best when soil temperatures are between 50 and 65 degrees F. This roughly corresponds to daytime air temperatures in the 60 F to 75 F range. As a general rule, plant cool-season grass seed at least 45 days before the estimated date of your first fall frost, before soil and air temperatures drop to less favorable levels. Your grasses will enjoy a full fall season, plus a second cool, growing season come spring.
Newly planted seed needs consistent soil moisture, and fall planting offers benefits on that front, too. Fall typically brings more rain, which lessens the chance that cool-season seeds may dry out, and reduces the need for extra watering on your part.
If you opt to install or repair your lawn using hydroseed or sod, fall is still the optimal time, as hydroseed and sod will also have better success in germinating and establishing root in fall conditions.
