Reading the Crystal Springs Exp Stn lawn year

Crystal Springs Exp Stn's lawn year runs on warmth: the lawn wakes after the last frost around Mar 11, hits full stride in midsummer, and goes dormant with the first frost around Nov 16. 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 Crystal Springs Exp Stn?

Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Mar 25 – Apr 8 in Crystal Springs Exp Stn, 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 Crystal Springs Exp Stn?

Aim for Feb 18 – Mar 11 — the estimated stretch when Crystal Springs Exp Stn soil approaches the ~55°F germination threshold, anchored to the average last frost (Mar 11). 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 Crystal Springs Exp Stn?

Keep mowing as long as the grass grows — in Crystal Springs Exp Stn that's typically until Nov 2 – Nov 23, around the average first fall frost (Nov 16). Warm-season lawns then go brown-dormant for winter, which is normal.
