The right mowing height for every grass type
Mowing too short is the most common mistake we see. Here’s the height for your grass and the one rule that matters more than the number.
Every grass type has a height range where it’s thickest and healthiest. Go below it and you invite weeds, heat stress and disease.
| Grass | Mowing height |
|---|---|
| Bermuda | 1–2″ |
| Zoysia | 1–2.5″ |
| St. Augustine | 3–4″ (dwarf types 2–2.5″) |
| Centipede | 1.5–2″ |
| Bahia | 3–4″ |
| Buffalo | 2–3″ |
| Tall Fescue | 3–4″ |
| Kentucky Bluegrass | 2.5–3.5″ |
The rule that matters more
Never cut off more than a third of the blade at once. If your St. Augustine is 6 inches tall, bring it to 4, then to 3.5 a few days later — not straight to 3.
Keep the blade sharp
A dull blade tears grass instead of cutting it, leaving ragged, brown tips. Sharpen it at least once a season.
