Reading the Wfo Brownsville lawn year

Wfo Brownsville's lawn year runs on warmth: the lawn wakes after the last frost around Jan 9, hits full stride in midsummer, and goes dormant with the first frost around Jan 4. 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 Wfo Brownsville?

Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Jan 23 – Feb 6 in Wfo Brownsville, 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 Wfo Brownsville?

Aim for Dec 19 – Jan 9 — the estimated stretch when Wfo Brownsville soil approaches the ~55°F germination threshold, anchored to the average last frost (Jan 9). 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 Wfo Brownsville?

Keep mowing as long as the grass grows — in Wfo Brownsville that's typically until Dec 21 – Jan 11, around the average first fall frost (Jan 4). Warm-season lawns then go brown-dormant for winter, which is normal.
