California Lawn Mowing Guide
California is really two lawn regions. The warm, dry south runs Bermuda and St. Augustine; the cooler, wetter north runs tall fescue. What they share is the state’s defining constraint — water restrictions — so the winning move everywhere is to mow a little higher, shade the soil, and never cut a drought-stressed lawn in midday heat.
What grass do you have?
- Bermuda (south) — heat- and drought-tough; cut low.
- St. Augustine (south, coastal) — shade-tolerant; cut high.
- Tall fescue (north) — the cool-season default; deep roots, heat-tolerant with a high cut.
Mowing heights for California grasses
| Grass | Mowing height | Notes |
|---|---|---|
| Bermuda | 1–2 in | South; raise slightly under heat stress |
| St. Augustine | 3.5–4 in | South/coastal; never scalp |
| Tall fescue | 3–4 in | North; keep at 3.5–4 in in summer to conserve moisture |
Mowing higher shades the soil and cuts watering needs — a real lever under drought rules.
California mowing calendar

| May | Peak growth; weekly cuts; check your district’s watering rules. |
| Jun | Heat and dry season begin; raise the deck; water within restrictions. |
| Jul | Peak heat — mow high, early or late in the day, never midday on stressed turf. |
| Aug | Hottest, driest stretch; hold the high cut; deep, infrequent watering. |
