Reading the Harper 3ENE lawn year
Harper 3ENE's lawn year runs on warmth: the lawn wakes after the last frost around Mar 15, hits full stride in midsummer, and goes dormant with the first frost around Nov 15. 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 Harper 3ENE?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Mar 29 – Apr 12 in Harper 3ENE, 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 Harper 3ENE?
Aim for Feb 22 – Mar 15 — the estimated stretch when Harper 3ENE soil approaches the ~55°F germination threshold, anchored to the average last frost (Mar 15). 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 Harper 3ENE?
Keep mowing as long as the grass grows — in Harper 3ENE that's typically until Nov 1 – Nov 22, around the average first fall frost (Nov 15). Warm-season lawns then go brown-dormant for winter, which is normal.
