Reading the Shamrock #2 lawn year
Shamrock #2's lawn year runs on warmth: the lawn wakes after the last frost around Apr 9, hits full stride in midsummer, and goes dormant with the first frost around Oct 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 Shamrock #2
Frequently asked questions
When should I plant warm-season grass in Shamrock #2?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Apr 23 – May 7 in Shamrock #2, 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 Shamrock #2?
Aim for Mar 19 – Apr 9 — the estimated stretch when Shamrock #2 soil approaches the ~55°F germination threshold, anchored to the average last frost (Apr 9). 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 Shamrock #2?
Keep mowing as long as the grass grows — in Shamrock #2 that's typically until Oct 16 – Nov 6, around the average first fall frost (Oct 30). Warm-season lawns then go brown-dormant for winter, which is normal.
