One of the most common questions homeowners ask is: how often should I mow my lawn? The honest answer depends on your grass type, the season, and how fast your specific lawn grows — but there are solid guidelines to work from.
The One-Third Rule
The most important rule in mowing is the one-third rule: never remove more than one-third of the grass blade in a single mowing. Cutting too much at once stresses the plant, exposes the soil to sun, and can brown out your lawn fast.
If your target height is 3 inches, mow when the grass reaches 4.5 inches. Simple.
Warm-Season vs. Cool-Season Grass
Grass type plays a big role in how fast it grows:
- Bermuda & Zoysia (common in Oklahoma) — grow fastest in summer heat. Weekly mowing from May through September is typical, sometimes every 5–6 days during peak growth.
- Fescue & Bluegrass — cool-season grasses that grow faster in spring and fall, slower in summer. Bi-weekly mowing often works during summer.
- St. Augustine — moderate growth rate, generally every 7–10 days during the growing season.
Seasonal Adjustments
In Oklahoma City and surrounding areas, a typical mowing calendar looks like this:
- March–April: Bi-weekly as grass comes out of dormancy
- May–August: Weekly, or every 5–6 days for Bermuda
- September–October: Bi-weekly as growth slows
- November–February: Dormant — little to no mowing needed
Signs You're Mowing Too Infrequently
- Grass looks shaggy or lays over sideways
- Clippings are too thick to break down quickly
- You're cutting off more than a third of the blade
- Weeds are getting ahead of the turf
The Bottom Line
For most Oklahoma lawns, a weekly mowing schedule from late spring through early fall is the sweet spot. Bi-weekly works during shoulder seasons. A professional lawn service will adjust based on what they actually see — and a good provider will never scalp your lawn to buy themselves more time between visits.
