Redlands lawn care, month by month
California 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 | Apply crabgrass pre-emergent · Light feeding after green-up · Final mow of the year | Apply crabgrass pre-emergent |
| February | Light feeding after green-up | Seed, sod, or plug new grass · First feeding at full green-up · Aerate / dethatch |
| March | Mow high (3–3.5″); water deeply in dry spells; no feeding in heat | First feeding at full green-up · Aerate / dethatch |
| April | Mow high (3–3.5″); water deeply in dry spells; no feeding in heat | Peak growth — regular mowing, about 1″ of water a week |
| May | Mow high (3–3.5″); water deeply in dry spells; no feeding in heat | Peak growth — regular mowing, about 1″ of water a week |
| June | Mow high (3–3.5″); water deeply in dry spells; no feeding in heat | Peak growth — regular mowing, about 1″ of water a week |
| 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 | Mow high (3–3.5″); water deeply in dry spells; no feeding in heat | Peak growth — regular mowing, about 1″ of water a week |
| September | Mow high (3–3.5″); water deeply in dry spells; no feeding in heat | Peak growth — regular mowing, about 1″ of water a week |
| October | Aerate + overseed · Main fall feeding | Last nitrogen of the year |
| November | Aerate + overseed · Main fall feeding · Winterizer feeding | Last nitrogen of the year |
| December | Winterizer feeding · Final mow of the year | Growth stops — final mow |
Reading the Redlands lawn year
Transition-zone timing cuts both ways in Redlands: cool-season lawns get their big renovation in early fall (overseed Oct 20 – Nov 4), while warm-season lawns establish in late spring (Feb 10 – Feb 24) and want their last feeding by Oct 24 – Nov 7. 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 Redlands?
For cool-season grass (bluegrass, fescue, ryegrass), overseed in early fall — in Redlands that means roughly Oct 20 – Nov 4, timed 45–60 days before the average first fall frost (Dec 19) so seedlings establish before cold. Spring works as a backup but collides with crabgrass season.
When should I plant warm-season grass in Redlands?
Seed, sod, or plug Bermuda, Zoysia, and other warm-season grasses in late spring — around Feb 10 – Feb 24 in Redlands, 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 Redlands?
Aim for Jan 6 – Jan 27 — the estimated stretch when Redlands soil approaches the ~55°F germination threshold, anchored to the average last frost (Jan 27). 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 Redlands?
Keep mowing as long as the grass grows — in Redlands that's typically until Dec 12 – Jan 2, around the average first fall frost (Dec 19). Take the final cut slightly shorter to discourage snow mold.
What grass grows best in Redlands?
California 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.
