Seed a New Lawn

Seeding a new lawn in Central Washington for best performance starts with the right season, the right variety of grasses, and soil preparation.

A number of lawn care and lawn establishment brochures are available from Washington State University Extension. We list several that will help you with your lawn care. We also have tailored some topics to our specific conditions here in Central Washington. These include when to seed, what seed varieties perform here, and turfgrass maintenance.

Seed in Spring or Fall

The best time of year to seed a new lawn in Central Washington is mid-August to mid-September, followed by April to May. These seasons are cooler so the seed bed is easier to keep moist for the germinating seed. In Central Washington, where irrigation water may be available, homeowners would time their planting to dates after water is turned on for the season, or before it is turned off in the Fall.

Choosing Seed

A blend of two varieties is recommended for Central Washington. The blends will vary depending on whether the lawn is in shade or sun.

For a lawn in a sunny area, we recommend a blend of about 80% Kentucky Blue and about 20% fine fescue. For our area, these varieties are recommended:

Kentucky Blue Creeping Red Fine Fescues
Eclipse- R
Glade- S
Majestic- – R
Midnight- R
Ram I- S
Sydsport- I
Victa- S

Resistance to necrotic ring spot
R= resistant
I= intermediate susceptibility
S= susceptible
