Reading the Baton Rouge lawn year
Baton Rouge's lawn year runs on warmth: the lawn wakes after the last frost around Feb 28, hits full stride in midsummer, and goes dormant with the first frost around Nov 26. 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 Baton Rouge?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Mar 14 – Mar 28 in Baton Rouge, 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 Baton Rouge?
Aim for Feb 7 – Feb 28 — the estimated stretch when Baton Rouge soil approaches the ~55°F germination threshold, anchored to the average last frost (Feb 28). 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 Baton Rouge?
Keep mowing as long as the grass grows — in Baton Rouge that's typically until Nov 12 – Dec 3, around the average first fall frost (Nov 26). Warm-season lawns then go brown-dormant for winter, which is normal.
