Mowing height & frequency
How high and how often to cut each lawn alternative — most need far less mowing than turf, and several need none at all.
Less mowing, by design
The whole point of a lawn alternative is to cut the mowing — and most do, dramatically. No-mow fine fescue is cut a handful of times a year; clover and microclover are optional; thyme, Sagina, moss and dichondra need no mowing at all. Heights and frequencies below are drawn from our verified species data and university cooperative extension (UMN, Penn State, UMD, NC State & CSU).
By species
| Species | Mowing height | Frequency | Notes |
|---|---|---|---|
| White clover | Mow high, ~3 in (holds 2–4 in) | 0–2× per year (optional) | Optional spring trim; never scalp |
| Microclover | 2–3 in (HOA) / unmown 2–4 in | 0–2× per year (optional) | Never below 1.5 in |
| Fine fescue (no-mow) | Falls to ~4–6 in mounds | 1–4× per year (≥1 fall cut) | Or mow conventionally at 2.5–4 in |
| Creeping thyme | 2–4 in (no-mow) | None; light shear after bloom | Full sun only |
| Chamomile | Low mat | None (Treneague no-mow) | Plug-established |
| Yarrow | Cut spent flower stems | Occasional | ⚠️ ASPCA-toxic to pets |
| Buffalograss | No-mow 4–6 in, or 2–3 in if mown | 0 to ~monthly | Warm-season native |
| Dichondra | 1–6 in (low/no-mow) | None to occasional | Warm climates |
| Irish/Scotch moss | 1–2 in mat | None | Part shade, moist |
| Sedge (Carex) | 2–4 in if mown | 1–3× per year or unmown | Dry-shade specialist |

The one rule that always applies
When you do mow, never remove more than one-third of the height in a single cut (the “one-third rule”). Scalping stresses roots, invites weeds and undoes the low-input advantage. Sharp blades and mowing when dry help too.
“No-mow” means after establishment
A no-mow lawn earns its name once it’s established (often 12–18 months in). During year one you may still mow 2–3 times to control weeds while the planting fills in — calling it no-mow from day one is the most common mistake. Fine-fescue no-mow lawns also benefit from at least one autumn cut to tidy up and reduce snow mould.
