Reading the Weslaco lawn year
Weslaco's lawn year runs on warmth: the lawn wakes after the last frost around Jan 8, hits full stride in midsummer, and goes dormant with the first frost around Dec 31. 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.
Grasses that fit Weslaco
Frequently asked questions
When should I plant warm-season grass in Weslaco?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Jan 22 – Feb 5 in Weslaco, 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 Weslaco?
Aim for Dec 18 – Jan 8 — the estimated stretch when Weslaco soil approaches the ~55°F germination threshold, anchored to the average last frost (Jan 8). 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 Weslaco?
Keep mowing as long as the grass grows — in Weslaco that's typically until Dec 17 – Jan 7, around the average first fall frost (Dec 31). Warm-season lawns then go brown-dormant for winter, which is normal.
