Reading the Perrine 4W lawn year
Perrine 4W's lawn year runs on warmth: the lawn wakes after the last frost around Jan 18, hits full stride in midsummer, and goes dormant with the first frost around Jan 13. 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 Perrine 4W
Frequently asked questions
When should I plant warm-season grass in Perrine 4W?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Feb 1 – Feb 15 in Perrine 4W, 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 Perrine 4W?
Aim for Dec 28 – Jan 18 — the estimated stretch when Perrine 4W soil approaches the ~55°F germination threshold, anchored to the average last frost (Jan 18). 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 Perrine 4W?
Keep mowing as long as the grass grows — in Perrine 4W that's typically until Dec 30 – Jan 20, around the average first fall frost (Jan 13). Warm-season lawns then go brown-dormant for winter, which is normal.
