Reading the Cullman Nahs lawn year
Cullman Nahs's lawn year runs on warmth: the lawn wakes after the last frost around Apr 7, hits full stride in midsummer, and goes dormant with the first frost around Oct 29. 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.
Grasses that fit Cullman Nahs
Frequently asked questions
When should I plant warm-season grass in Cullman Nahs?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Apr 21 – May 5 in Cullman Nahs, 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 Cullman Nahs?
Aim for Mar 17 – Apr 7 — the estimated stretch when Cullman Nahs soil approaches the ~55°F germination threshold, anchored to the average last frost (Apr 7). 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 Cullman Nahs?
Keep mowing as long as the grass grows — in Cullman Nahs that's typically until Oct 15 – Nov 5, around the average first fall frost (Oct 29). Warm-season lawns then go brown-dormant for winter, which is normal.
