Reading the Seymour 3NW lawn year
Seymour 3NW's lawn year runs on warmth: the lawn wakes after the last frost around Mar 30, hits full stride in midsummer, and goes dormant with the first frost around Nov 6. The two dates to respect most are the pre-emergent deadline in late winter — southern soil warms early — and the last-nitrogen cutoff 6–8 weeks before frost, which protects the lawn from winter injury.

Frequently asked questions
When should I plant warm-season grass in Seymour 3NW?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Apr 13 – Apr 27 in Seymour 3NW, once soil has warmed well past the last frost. That gives new grass a full growing season to mature before its first winter dormancy.
When do I put down crabgrass preventer in Seymour 3NW?
Aim for Mar 9 – Mar 30 — the estimated stretch when Seymour 3NW soil approaches the ~55°F germination threshold, anchored to the average last frost (Mar 30). It's an estimate: a soil thermometer reading 50–55°F at 2″ depth for several days is the precise trigger, and pre-emergent must go down before crabgrass sprouts, not after.
When should I stop mowing in Seymour 3NW?
Keep mowing as long as the grass grows — in Seymour 3NW that's typically until Oct 23 – Nov 13, around the average first fall frost (Nov 6). Warm-season lawns then go brown-dormant for winter, which is normal.
