Reading the Jacksonville Beach lawn year
Jacksonville Beach's lawn year runs on warmth: the lawn wakes after the last frost around Jan 31, hits full stride in midsummer, and goes dormant with the first frost around Jan 10. 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 Jacksonville Beach?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Feb 14 – Feb 28 in Jacksonville Beach, 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 Jacksonville Beach?
Aim for Jan 10 – Jan 31 — the estimated stretch when Jacksonville Beach soil approaches the ~55°F germination threshold, anchored to the average last frost (Jan 31). 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 Jacksonville Beach?
Keep mowing as long as the grass grows — in Jacksonville Beach that's typically until Dec 27 – Jan 17, around the average first fall frost (Jan 10). Warm-season lawns then go brown-dormant for winter, which is normal.
