Pick a grass and a goal to get a personalized schedule, tuned to USDA Zone 6B.
- 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.
Silt retains moisture well — keep the seedbed consistently damp with about ¼ inch once daily, easing off if the surface stays wet to avoid damping-off.
County-specific frost normals aren’t available for Effingham County, so this plan uses USDA Zone 6B timing rather than exact local dates. Adjust to your own first and last frost when you know them.
