  • The best time of day to cut grass is mid-morning between 8 a.m. and 10 a.m. when your lawn is dry and ready to recover.

  • Lawn mowing costs $130 per visit on average, with prices ranging from $50 to $210 depending on your yard size and terrain.

  • Avoid mowing when your grass is wet from morning dew or after dark, as moisture causes torn blades and increases fungal infection risk.

  • Hiring a local lawn care professional keeps your mowing schedule consistent and removes the stress of timing, helping your lawn stay healthy and well-maintained.

Many lawn maintenance enthusiasts face the same question: When is the best time to cut the grass? While there’s some debate on the significance of how you time your trimming, there are seeds of sound logic to consider. Let’s take a look at what plays into the ideal time to mow your lawn.

When to Mow the Grass

The best time to cut the grass is in the middle of the morning between 8 a.m. to 10 a.m. This timing allows the grass sufficient time to let go of the morning’s dew while still being able to recover in time for the intense afternoon sunshine.

If you can’t mow in the morning, the next-best time is late afternoon to early evening. Ideally between 4 p.m. and 6 p.m. It's still warm during this timeframe, but the sun isn't as strong, so there's less risk of burning your grass. Plus, it gives your lawn time to recover before it gets dark.

Factors That Affect the Best Time to Cut Grass

Check out the main factors to consider when determining the best time to cut your grass.

Climate

Periods of heavy rain or flooding are not the best time to cut grass, as the blades will be wet and vulnerable to damage from the lawnmower. Heat waves are another thing to look out for, as these can cause heat stress in plants, including grass. You should skip cutting the grass if the temperature is more than 90 degrees because the grass is already stressed from the heat and mowing can worsen the issue.

Season

The time of year plays some part in the best time to cut grass. During the spring and early summer, when the heat isn’t as intense, you can often mow later in the afternoon without as much concern for the sun stressing and damaging the grass. When mowing in high temperatures, you may need to start cutting the grass closer to 7 a.m. or 8 a.m. rather than waiting until 10 a.m. or later.

Sunlight

Extreme sunlight or heat waves can potentially burn your grass, so you want to keep the blades long to protect the fresh growth closer to the soil. Likewise, overcast days (especially after rainfall) may not be the best time to cut grass. The sun helps dry out the excess moisture from grass so blades may still be wet and not ideal for mowing.  

Personal Schedule

While there is a best time to mow grass based on the time of day, personal schedules are still a major factor in this task. If you have an early workday that makes it difficult to keep up your lawn mowing routine, it’s easy to fall off track. In that case, consider the option to hire a local lawn care service to ensure your grass remains in prime condition without sacrificing your work or personal schedule.

The worst time to cut grass is in the early morning between 5 a.m. to 8 a.m. This timing is potentially bothersome to your neighbors, and it can also be harmful to your grass and your lawn mower. Avoid cutting during this time because grass is wet with morning dew early in the morning, causing wet grass blades to tear and lawn mower blades to dull

Another poor time to cut grass is after sundown. Similar to the early morning, grass often becomes dewy and wet as it gets dark. Plus, lawns are vulnerable to lawn mushrooms and other fungal infections during that time. There’s also very limited visibility, which may cause you to miss spots, run over stray objects, or even get injured. For safety reasons and to keep your lawn looking even and healthy, stick to the mid-morning or early evening hours.

Cost to Mow a Lawn

The average cost to mow a lawn is $130 per visit, although prices generally vary between $50 and $210. For larger yards, costs can range from $50 to $200 per acre. Prices vary based on factors such as the size and shape of the lawn, the time it takes to mow, and the presence of obstacles that the lawn care professional needs to maneuver around.  

DIY vs. Hiring a Pro

Learning how to mow a lawn and keep a regular schedule is an approachable DIY task that can save around $130 per session. However, lawn mowing can quickly become exhausting and monotonous, and it's common to lose track of time between sessions. Consistent care is crucial for the health of your lawn, and hiring a local lawn care professional means you have one less task to worry about in maintaining the health and beauty of your lawn.

Frequently Asked Questions

When spring arrives, it’s best to hold off on mowing until temperatures have consistently reached a temperature of at least 40 degrees Fahrenheit. Attempting to mow grass that hasn't fully thawed from its winter dormancy can harm the delicate blades. Ensure your grass is dry before mowing and aim to mow when the grass is about three to four inches tall, trimming no more than one-third of the grass blade's height at a time. This timing encourages healthy growth and prevents shock to the grass, preparing your lawn for a happy, healthy growing season.

No, it isn’t illegal, but many cities and towns have noise ordinances that it could violate. Either way, it can still cause problems if it bothers your neighbors. For motor-powered lawnmowers, the general consensus for common courtesy is to wait until after 8 a.m. to mow your lawn. However, if you have a push mower, you should be safe to mow at any time of day, provided you don’t make excessive noise in other ways.

Mowing at least once a week during the growing season is a good general rule. However, every lawn is different, and factors like frequent rain and fertilizer use can cause grass to grow faster, potentially requiring mowing as often as every four days. When you mow, always follow the 'one-third rule': never cut more than one-third of the grass blade's height at once, as this can weaken it and prevent it from taking in proper nutrients. For most grass types, the ideal height is around 2 to 3 inches, though some warm-weather grasses do better when kept shorter at about 1.5 to 2 inches.
