Reading the Charleston International Airport lawn year
Charleston International Airport'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 27. 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 Charleston International Airport?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Mar 21 – Apr 4 in Charleston International 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 Charleston International Airport?
Aim for Feb 14 – Mar 7 — the estimated stretch when Charleston International Airport 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 Charleston International Airport?
Keep mowing as long as the grass grows — in Charleston International Airport that's typically until Nov 13 – Dec 4, around the average first fall frost (Nov 27). Warm-season lawns then go brown-dormant for winter, which is normal.
