Reading the St Petersburg International Airport lawn year

St Petersburg International Airport's lawn year runs on warmth: the lawn wakes after the last frost around Jan 17, hits full stride in midsummer, and goes dormant with the first frost around Jan 14. 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 St Petersburg International Airport?

Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Jan 31 – Feb 14 in St Petersburg 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 St Petersburg International Airport?

Aim for Dec 27 – Jan 17 — the estimated stretch when St Petersburg International Airport soil approaches the ~55°F germination threshold, anchored to the average last frost (Jan 17). 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 St Petersburg International Airport?

Keep mowing as long as the grass grows — in St Petersburg International Airport that's typically until Dec 31 – Jan 21, around the average first fall frost (Jan 14). Warm-season lawns then go brown-dormant for winter, which is normal.
