How Low Should You Mow
What Mowing Height Should a Lawn Mower Be Set At?
Finding the perfect mowing height isn't guesswork—it’s about knowing your grass and adjusting for the season. At M&D Enterprises, we believe a properly cut lawn is the first step to a lush, healthy yard that thrives here in Oklahoma.

1. Know Your Grass Type & Location
- Cool-Season Grasses
(Bluegrass, Rye, Fescue – common north of St. Louis):
- Spring & Fall:
2″–2½″ for optimal growth
- Summer:
Raise to ~3″ to reduce heat stress
- Warm-Season Grasses
(Bermuda, Zoysia, Bahiagrass – typical in Oklahoma):
- Spring/Fall: 1″–2″—they tolerate shorter heights well
- Summer: Consistent 1″–2″ works for vigorous growth

2. Measure & Adjust Correctly
- Deck height numbers may not match actual cut—test by mowing a small patch and
measuring it.
- Follow the
1/3 Rule:
Never remove more than one-third of the grass blade per mowing.
- Aim for trimming no more than 1″ at a time during peak growth. Multiple sessions per week may be ideal during spring and fall.
3. Caring for New Grass Seed or Sod
- Sod: Wait at least 10 days or until vigorous growth before mowing.
- Seed, Plugs, or Sprigs: Let grass reach 3"-4" tall before the first cut.
4. The Case for Tall Grass
- Taller grass provides shade, retains soil moisture, and
builds deep roots.
- It grows slower, leading to fewer mows—saving you up to 20% of mowing time annually.
- It also reduces weed intrusion—less need for herbicides!
5. Why Cutting Too Short Harms Your Lawn
- Short cuts stress grass and force it to use root reserves, weakening the plant.
- Shallow roots dry out faster and are
less resilient to drought and heat.
- Tall grass = deeper roots, better health, and a
greener lawn.

💡 Final Takeaway
- Identify your grass and
know your zone (warm vs. cool season).
- Aim for 1″–2½″ based on
grass type and season.
- Avoid cutting more than 1/3 of grass at a time.
- Leave new lawns longer until established.
- Choose height that supports depth, strength, and overall lawn health.
