Reading the St Martinville 3 SW lawn year
St Martinville 3 SW's lawn year runs on warmth: the lawn wakes after the last frost around Feb 21, hits full stride in midsummer, and goes dormant with the first frost around Nov 27. 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 St Martinville 3 SW?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Mar 7 – Mar 21 in St Martinville 3 SW, 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 St Martinville 3 SW?
Aim for Jan 31 – Feb 21 — the estimated stretch when St Martinville 3 SW soil approaches the ~55°F germination threshold, anchored to the average last frost (Feb 21). 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 St Martinville 3 SW?
Keep mowing as long as the grass grows — in St Martinville 3 SW that's typically until Nov 13 – Dec 4, around the average first fall frost (Nov 27). Warm-season lawns then go brown-dormant for winter, which is normal.
