- 1Prepare the seedbed
Mow low, dethatch or rake, and loosen the top ½ inch of soil about two weeks before seeding.
- 2Sow seed
Based on your USDA zone (county-specific frost data unavailable), sow Kentucky Bluegrass in early fall (and early spring as a backup).
- 3Establish
Keep the seedbed moist through germination (5–21 days depending on species), then transition to deeper, less frequent watering.
Keep the seedbed consistently moist — roughly ¼ inch of water daily, split into shorter cycles if the surface dries out quickly. County-specific soil texture isn’t available here, so adjust to how fast your own soil drains.
