Cool-season lawns

TaskAngel Fire 1S windowWhy then
Crabgrass pre-emergent May 28 – Jun 18 Soil nearing 55°F — must beat germination
Light spring feeding Jun 18 – Jul 16 After green-up, before summer stress
Aerate + overseed Jul 10 – Jul 25 Fall growth surge; established before cold
Main fall feeding Jul 14 – Aug 11 The year’s most important nitrogen
Winterizer feeding Aug 11 – Aug 25 Root reserves for spring green-up
Final mow Sep 1 – Sep 22 Growth stops around first frost

Warm-season lawns

TaskAngel Fire 1S windowWhy then
Crabgrass pre-emergent May 28 – Jun 18 Southern soil warms early — don’t be late
Seed / sod / establish Jul 2 – Jul 16 Soil 65–70°F; a full season to mature
First feeding Jul 9 – Jul 30 At full green-up, not before
Aerate / dethatch Jul 16 – Aug 13 Peak growth heals the disturbance fast
Last nitrogen Jul 14 – Jul 28 6–8 weeks before frost — then stop
Growth stops / final mow Aug 25 – Sep 15 Dormancy arrives with first frost

Angel Fire 1S 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 Angel Fire 1S lawn year

Transition-zone timing cuts both ways in Angel Fire 1S: cool-season lawns get their big renovation in early fall (overseed Jul 10 – Jul 25), while warm-season lawns establish in late spring (Jul 2 – Jul 16) and want their last feeding by Jul 14 – Jul 28. 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 Angel Fire 1S?

For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Angel Fire 1S that means roughly Jul 10 – Jul 25, timed 45–60 days before the average first fall frost (Sep 8) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.

When should I plant warm-season grass in Angel Fire 1S?

Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Jul 2 – Jul 16 in Angel Fire 1S, 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 Angel Fire 1S?

Aim for May 28 – Jun 18 — the estimated stretch when Angel Fire 1S soil approaches the ~55°F germination threshold, anchored to the average last frost (Jun 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 Angel Fire 1S?

Keep mowing as long as the grass grows — in Angel Fire 1S that's typically until Sep 1 – Sep 22, around the average first fall frost (Sep 8). Take the final cut slightly shorter to discourage snow mold.

What grass grows best in Angel Fire 1S?

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.
