Reading the Oasis Rs lawn year

Oasis Rs'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 16. 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 Oasis Rs

Frequently asked questions

When should I plant warm-season grass in Oasis Rs?

Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Feb 1 – Feb 15 in Oasis Rs, 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 Oasis Rs?

Aim for Dec 28 – Jan 18 — the estimated stretch when Oasis Rs 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 Oasis Rs?

Keep mowing as long as the grass grows — in Oasis Rs that's typically until Jan 2 – Jan 23, around the average first fall frost (Jan 16). Warm-season lawns then go brown-dormant for winter, which is normal.
