Reading the Hattiesburg 5SW lawn year
Hattiesburg 5SW's lawn year runs on warmth: the lawn wakes after the last frost around Mar 7, hits full stride in midsummer, and goes dormant with the first frost around Nov 23. 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 Hattiesburg 5SW?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Mar 21 – Apr 4 in Hattiesburg 5SW, 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 Hattiesburg 5SW?
Aim for Feb 14 – Mar 7 — the estimated stretch when Hattiesburg 5SW soil approaches the ~55°F germination threshold, anchored to the average last frost (Mar 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 Hattiesburg 5SW?
Keep mowing as long as the grass grows — in Hattiesburg 5SW that's typically until Nov 9 – Nov 30, around the average first fall frost (Nov 23). Warm-season lawns then go brown-dormant for winter, which is normal.
