Newton lawn care, month by month
Kansas 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.
| Month | Cool-season lawns | Warm-season lawns |
|---|---|---|
| January | Dormant — keep leaves cleared, stay off frozen turf | Dormant (brown is normal) — no nitrogen, light cleanup only |
| February | Dormant — keep leaves cleared, stay off frozen turf | Dormant (brown is normal) — no nitrogen, light cleanup only |
| March | Apply crabgrass pre-emergent | Apply crabgrass pre-emergent |
| April | Apply crabgrass pre-emergent · Light feeding after green-up | Apply crabgrass pre-emergent · Seed, sod, or plug new grass |
| May | Light feeding after green-up | Seed, sod, or plug new grass · First feeding at full green-up · Aerate / dethatch |
| June | Mow high (3–3.5″); water deeply in dry spells; no feeding in heat | Aerate / dethatch |
| July | Mow high (3–3.5″); water deeply in dry spells; no feeding in heat | Peak growth — regular mowing, about 1″ of water a week |
| August | Aerate + overseed · Main fall feeding | Last nitrogen of the year |
| September | Aerate + overseed · Main fall feeding · Winterizer feeding | Last nitrogen of the year |
| October | Winterizer feeding · Final mow of the year | Growth stops — final mow |
| November | Final mow of the year | Growth stops — final mow |
| December | Dormant — keep leaves cleared, stay off frozen turf | Dormant (brown is normal) — no nitrogen, light cleanup only |
Reading the Newton lawn year
Transition-zone timing cuts both ways in Newton: cool-season lawns get their big renovation in early fall (overseed Aug 26 – Sep 10), while warm-season lawns establish in late spring (Apr 28 – May 12) and want their last feeding by Aug 30 – Sep 13. 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 Newton?
For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Newton that means roughly Aug 26 – Sep 10, timed 45–60 days before the average first fall frost (Oct 25) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.
When should I plant warm-season grass in Newton?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Apr 28 – May 12 in Newton, 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 Newton?
Aim for Mar 24 – Apr 14 — the estimated stretch when Newton soil approaches the ~55°F germination threshold, anchored to the average last frost (Apr 14). 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 Newton?
Keep mowing as long as the grass grows — in Newton that's typically until Oct 18 – Nov 8, around the average first fall frost (Oct 25). Take the final cut slightly shorter to discourage snow mold.
What grass grows best in Newton?
Kansas 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.
