Reading the Richardson lawn year
Richardson'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 21. 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 Richardson
Frequently asked questions
When should I plant warm-season grass in Richardson?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Mar 21 – Apr 4 in Richardson, 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 Richardson?
Aim for Feb 14 – Mar 7 — the estimated stretch when Richardson 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 Richardson?
Keep mowing as long as the grass grows — in Richardson that's typically until Nov 7 – Nov 28, around the average first fall frost (Nov 21). Warm-season lawns then go brown-dormant for winter, which is normal.
