Crabgrass pre-emergent Jan 12 – Feb 2 Southern soil warms early — don’t be late
Seed / sod / establish Feb 16 – Mar 2 Soil 65–70°F; a full season to mature
First feeding Feb 23 – Mar 16 At full green-up, not before
Aerate / dethatch Mar 2 – Mar 30 Peak growth heals the disturbance fast
Last nitrogen Nov 9 – Nov 23 6–8 weeks before frost — then stop
Growth stops / final mow Dec 21 – Jan 11 Dormancy arrives with first frost

Reading the Fernandina Beach lawn year

Fernandina Beach's lawn year runs on warmth: the lawn wakes after the last frost around Feb 2, hits full stride in midsummer, and goes dormant with the first frost around Jan 4. 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.

Grasses that fit Fernandina Beach

Frequently asked questions

When should I plant warm-season grass in Fernandina Beach?

Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Feb 16 – Mar 2 in Fernandina 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 Fernandina Beach?

Aim for Jan 12 – Feb 2 — the estimated stretch when Fernandina Beach soil approaches the ~55°F germination threshold, anchored to the average last frost (Feb 2). 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 Fernandina Beach?

Keep mowing as long as the grass grows — in Fernandina Beach that's typically until Dec 21 – Jan 11, around the average first fall frost (Jan 4). Warm-season lawns then go brown-dormant for winter, which is normal.
