Reading the San Antonio Stinson Airport lawn year

San Antonio Stinson Airport's lawn year runs on warmth: the lawn wakes after the last frost around Feb 20, hits full stride in midsummer, and goes dormant with the first frost around Dec 3. 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 San Antonio Stinson Airport?

Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Mar 6 – Mar 20 in San Antonio Stinson Airport, 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 San Antonio Stinson Airport?

Aim for Jan 30 – Feb 20 — the estimated stretch when San Antonio Stinson Airport soil approaches the ~55°F germination threshold, anchored to the average last frost (Feb 20). 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 San Antonio Stinson Airport?

Keep mowing as long as the grass grows — in San Antonio Stinson Airport that's typically until Nov 19 – Dec 10, around the average first fall frost (Dec 3). Warm-season lawns then go brown-dormant for winter, which is normal.
