When Should You Plant Grass Seed?

By Staff WriterLast Updated December 10, 2023

When grass seed should be planted depends on the type of grass. Cool-season grasses such as tall fescue and Kentucky bluegrass should be planted in the fall. Warm-season grasses like St. Augustine and Bermuda should be planted in the spring.

Homeowners should choose grass based on the climate in which they live. Cool-season grasses grow in temperatures ranging from 65 to 80 degrees Fahrenheit. They thrive in areas of Northern California, the Upper Midwest, the High Plains and New England.

Warm-season grasses grow best in the southern United States, from Nevada to Florida. They grow best in temperatures ranging from 75 to 90 degrees, and they grow very quickly in the summer months.
