Reading the Marrero 9 SSW lawn year
Marrero 9 SSW's lawn year runs on warmth: the lawn wakes after the last frost around Feb 10, hits full stride in midsummer, and goes dormant with the first frost around Dec 12. 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 Marrero 9 SSW?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Feb 24 – Mar 10 in Marrero 9 SSW, 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 Marrero 9 SSW?
Aim for Jan 20 – Feb 10 — the estimated stretch when Marrero 9 SSW soil approaches the ~55°F germination threshold, anchored to the average last frost (Feb 10). 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 Marrero 9 SSW?
Keep mowing as long as the grass grows — in Marrero 9 SSW that's typically until Nov 28 – Dec 19, around the average first fall frost (Dec 12). Warm-season lawns then go brown-dormant for winter, which is normal.
