Cool-Season Grass Planting Windows

Cool-season grasses (tall fescue, Kentucky bluegrass, perennial ryegrass) germinate best when the 2-inch soil temperature stays between 50°F and 65°F. The ideal window is early to mid-spring, or early fall when soil cools back into this range. Fall seeding has less weed competition and more consistent moisture.

• Spring: Seed when soil sustains 50°F+ for 3–5 consecutive days.
• Fall: Seed 6–8 weeks before the first hard freeze so roots establish.
• Avoid: Mid-summer seeding when soil exceeds 75°F — germination drops and weed pressure peaks.

Warm-Season Grass Planting Windows

Warm-season grasses (Bermuda, zoysia, St. Augustine, centipede) need soil temperatures of 65°F–70°F or higher for germination. These grasses are best seeded in late spring through early summer when soil has fully warmed.

• Late spring: Seed once soil sustains 65°F+ for 5–7 days.
• Sod: Can be laid slightly earlier since it is already established, but root growth still needs 60°F+ soil.
• Avoid: Fall seeding — warm-season seeds will not germinate before winter dormancy.

How to Check Before You Seed

Use a soil thermometer at 2 inches depth, measured mid-morning after the sun has warmed the surface. Take readings in several spots and average them. One warm day does not mean soil is ready — look for a sustained trend across 3–5 days.
