How often to cut grass is one of the most common questions homeowners ask when aiming for a lush, green lawn. The answer isn’t one-size-fits-all it depends on your grass type, season, growth rate, and weather.

This guide breaks down how often to cut grass, ideal mowing heights, and lawn mower tips to help you maintain healthy turf year-round. Whether you're using a manual, gas, or robot lawn mower, sticking to a proper mowing schedule is key to vibrant lawn health.

What Factors Affect Your Lawn Mowing Frequency?

1. What Season Are You In?

Spring and early summer = Fast growth = More mowing
Fall and winter = Dormancy = Less mowing

2. How’s the Weather?

More rain = More growth
Drought = Less mowing, higher grass helps shade soil

3. How Much Foot Traffic Does Your Lawn Get?
High-traffic areas look worn faster and may need more frequent mowing for aesthetics.

4. How Low Are You Cutting?
Cutting lower requires more frequent mowing. Always stick to the one-third rule, which is not to cut 1/3 of the length of the blade at a time./

5. Is Your Lawn Fertilized or Irrigated?
A well-fed, regularly watered lawn will grow quicker and require more attention.

Seasonal Impact on Lawn Mowing Frequency

Season & Growth Rate

Grass grows faster in its peak season (spring for cool-season, summer for warm-season).
Example: Kentucky Bluegrass might need mowing every 5 days in spring but every 10 days in summer.

Weather Conditions

Rain: Boosts growth, so you’ll mow more often.
Drought: Slows growth; mow less and keep grass taller to shield roots.

Lawn Use:

Busy areas may need more frequent cuts to stay tidy.
Mower Blade Height

Follow the one-third rule—never cut more than one-third of the grass height at a time.

Fertilization & Irrigation

Well-fertilized and irrigated lawns grow faster and need more mowing.

Grass Type	Category	Mowing Frequency	Recommended Height
Kentucky Bluegrass	Cool-Season	Every 5-7 days	0.75 - 3.5 inches
Tall Fescue	Cool-Season	Every 7-10 days	1.5 - 4 inches
Perennial Ryegrass	Cool-Season	Every 5-7 days	0.75- 3.5 inches
Fine Fescue	Cool-Season	Every 10-14 days	1.5 - 4 inches
Bermudagrass	Warm-Season	Every 3-7 days	0.5-2.5 inches
Zoysiagrass	Warm-Season	Every 7-10 days	0.5 - 3 inches
St. Augustinegrass	Warm-Season	Every 7-14 days	1 - 3 inches
Centipedegrass	Warm-Season	Every 10-14 days	1 - 2.5 inches
Buffalograss	Warm-Season	Every 10-14 days	1.5- 4 inches

Pro Tip: according to different seasons/temperature/humidity (humidity/temperature sensor + electronic clock), identify different types of grass, intelligent adjustment; you can also adjust according to their preferences

Mowing Best Practices

Keep your lawn thriving with these tips:

Change lawn mowing patterns: Avoid compacting soil and promote even growth.
