TaskSavannah windowWhy then
Crabgrass pre-emergent Feb 9 – Mar 2 Southern soil warms early — don’t be late
Seed / sod / establish Mar 16 – Mar 30 Soil 65–70°F; a full season to mature
First feeding Mar 23 – Apr 13 At full green-up, not before
Aerate / dethatch Mar 30 – Apr 27 Peak growth heals the disturbance fast
Last nitrogen Oct 5 – Oct 19 6–8 weeks before frost — then stop
Growth stops / final mow Nov 16 – Dec 7 Dormancy arrives with first frost

Reading the Savannah lawn year

Savannah's lawn year runs on warmth: the lawn wakes after the last frost around Mar 2, hits full stride in midsummer, and goes dormant with the first frost around Nov 30. 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 Savannah

Frequently asked questions

When should I plant warm-season grass in Savannah?

Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Mar 16 – Mar 30 in Savannah, 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 Savannah?

Aim for Feb 9 – Mar 2 — the estimated stretch when Savannah soil approaches the ~55°F germination threshold, anchored to the average last frost (Mar 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 Savannah?

Keep mowing as long as the grass grows — in Savannah that's typically until Nov 16 – Dec 7, around the average first fall frost (Nov 30). Warm-season lawns then go brown-dormant for winter, which is normal.
