Cool-season lawns

TaskAugustine 2E windowWhy then
Crabgrass pre-emergent Apr 28 – May 19 Soil nearing 55°F — must beat germination
Light spring feeding May 19 – Jun 16 After green-up, before summer stress
Aerate + overseed Aug 5 – Aug 20 Fall growth surge; established before cold
Main fall feeding Aug 9 – Sep 6 The year’s most important nitrogen
Winterizer feeding Sep 6 – Sep 20 Root reserves for spring green-up
Final mow Sep 27 – Oct 18 Growth stops around first frost

Warm-season lawns

TaskAugustine 2E windowWhy then
Crabgrass pre-emergent Apr 28 – May 19 Southern soil warms early — don’t be late
Seed / sod / establish Jun 2 – Jun 16 Soil 65–70°F; a full season to mature
First feeding Jun 9 – Jun 30 At full green-up, not before
Aerate / dethatch Jun 16 – Jul 14 Peak growth heals the disturbance fast
Last nitrogen Aug 9 – Aug 23 6–8 weeks before frost — then stop
Growth stops / final mow Sep 20 – Oct 11 Dormancy arrives with first frost

Augustine 2E lawn care, month by month

New Mexico sits in the turf transition zone, so the calendar depends on which grass family you have — they run on opposite schedules. Cool-season lawns (tall fescue, bluegrass) peak in spring and fall; warm-season lawns (Bermuda, Zoysia) do everything in the warm half. Not sure which you have? Start with the grass identification guides.

Reading the Augustine 2E lawn year

Transition-zone timing cuts both ways in Augustine 2E: cool-season lawns get their big renovation in early fall (overseed Aug 5 – Aug 20), while warm-season lawns establish in late spring (Jun 2 – Jun 16) and want their last feeding by Aug 9 – Aug 23. The one shared date is the pre-emergent window in spring — both families need crabgrass stopped before soil crosses 55°F.

Frequently asked questions

When should I overseed my lawn in Augustine 2E?

For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Augustine 2E that means roughly Aug 5 – Aug 20, timed 45–60 days before the average first fall frost (Oct 4) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.

When should I plant warm-season grass in Augustine 2E?

Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Jun 2 – Jun 16 in Augustine 2E, 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 Augustine 2E?

Aim for Apr 28 – May 19 — the estimated stretch when Augustine 2E soil approaches the ~55°F germination threshold, anchored to the average last frost (May 19). 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 Augustine 2E?

Keep mowing as long as the grass grows — in Augustine 2E that's typically until Sep 27 – Oct 18, around the average first fall frost (Oct 4). Take the final cut slightly shorter to discourage snow mold.

What grass grows best in Augustine 2E?

New Mexico is in the turf transition zone, so both families are common: Tall fescue and Kentucky bluegrass alongside Bermuda and Zoysia. Tall fescue is the usual cool-season pick and Bermuda or Zoysia the warm-season ones — they run on opposite calendars, so identify what you have first. See the grass guides linked below for identification and care.
