The Optimum Season To Begin Lawn Mowing

The best time to start mowing the lawn is in the morning, before the heat of the day sets in. Mowing your lawn may seem like a simple task, but timing is key to ensure a healthy and vibrant lawn. Starting early in the morning allows you to take advantage of cooler temperatures, which are better for both you and your grass. As the day progresses, the sun’s rays become more intense, and mowing during this time can stress and damage your grass. By starting early, you also avoid disturbing your neighbors with the noise of a lawnmower later in the day. Additionally, morning mowing gives your lawn ample time to dry before evening, reducing the risk of fungal growth. So set your alarm clock, grab your trusty lawnmower, and make the most of the cool morning hours to keep your lawn looking its best.

Best Time to Start Mowing the Lawn


Keeping your lawn well-maintained is essential for a beautiful and healthy outdoor space. One of the key aspects of lawn care is mowing, but do you know the best time to start mowing your lawn? In this article, we will explore the various factors that determine the ideal time to begin mowing and provide you with expert advice to achieve a well-groomed lawn. Whether you are a seasoned gardener or a beginner, this guide will help you make informed decisions regarding lawn mowing schedules.

The Impact of Seasonality

The time of year plays a crucial role in determining when to start mowing your lawn. Different seasons bring different growth rates, weather conditions, and maintenance needs. Here is a breakdown of the best time to start mowing during each season:


Spring is a time of renewal and growth, and your lawn is no exception. As the temperatures rise and the grass begins to wake up from its winter dormancy, it’s time to start mowing. Here are a few key considerations for spring mowing:

  • Wait until the soil temperature reaches around 55°F (13°C) consistently for a few days before mowing for the first time.
  • Set your mower blade to a higher setting initially to avoid cutting the grass too short.
  • Mow every 5-7 days to maintain an appropriate height and encourage healthy growth.
  • Ensure your mower blade is sharp to prevent tearing the grass.

Summer brings warm temperatures and increased rainfall, creating optimal conditions for your lawn to flourish. However, it also means more frequent mowing. Here’s what you need to know about mowing during the summer months:

  • Mow when the grass reaches about 3 ½ – 4 inches (9-10 cm) in height to prevent stress on the grass.
  • Consider adjusting your mowing schedule to early morning or late evening to avoid mowing during the hottest part of the day.
  • Don’t remove more than a third of the grass blade length in a single mowing session to avoid shocking the grass.


Fall is a transitional season that requires special attention to prepare your lawn for the upcoming winter months. Here’s what you need to keep in mind when mowing in the fall:

  • Continue regular mowing until the grass growth slows down, usually around the first frost.
  • Gradually lower the mower blade height for the last few mowing sessions to help the grass withstand the winter.
  • Collect fallen leaves before mowing or use a mulching mower to shred and recycle them.


Winter is a time of dormancy for most lawns, and mowing is generally not necessary during this season. However, if you live in an area with mild winters, you may need to occasionally mow to keep the grass at an appropriate height. Only mow when the ground is not frozen and the grass is actively growing.

Factors Affecting Mowing Frequency

Apart from the seasonal considerations, several other factors can influence how often you should mow your lawn. Here are some key factors to keep in mind:

Grass Type

Different grass types have varying growth habits, which will affect how frequently you need to mow. For example:

  • Cool-season grasses such as Kentucky bluegrass and fescue generally require more frequent mowing compared to warm-season grasses.
  • Warm-season grasses like Bermuda grass and zoysia grass tend to grow more slowly and may not require as frequent mowing.
  • Research the specific characteristics of your grass type to determine the recommended mowing frequency.

Growth Rate

The growth rate of your lawn can vary depending on factors such as rainfall, temperature, and soil fertility. Keep an eye on how quickly your grass is growing and adjust your mowing schedule accordingly. Regular mowing promotes a healthier lawn by preventing overgrowth and maintaining a consistent height.

Weather Conditions

Weather conditions also play a significant role in determining when to start mowing your lawn. If it has been raining heavily, it’s best to wait until the grass has dried out to avoid causing damage to the turf.

Mower Maintenance

Maintaining your mower is crucial for achieving clean and precise cuts. Dull mower blades can tear the grass instead of cleanly slicing through it, leading to a ragged appearance and increased susceptibility to diseases. Regularly sharpen the blades and ensure the mower is in good working condition to achieve optimal mowing results.

Knowing the best time to start mowing your lawn can make a significant difference in the overall health and appearance of your outdoor space. By considering seasonal variations, grass type, growth rate, weather conditions, and mower maintenance, you can develop a mowing schedule that keeps your lawn thriving. Remember to adjust your mowing height and frequency as needed to accommodate changing conditions throughout the year. With proper care and attention, you can achieve a vibrant, well-manicured lawn that will be the envy of your neighborhood.

When To Start Mowing Your lawn At The Beginning Of The Season

Frequently Asked Questions

What is the best time to start mowing the lawn?

The best time to start mowing the lawn is in the morning, preferably between 8:00 am and 10:00 am. At this time, the grass is still dry from the morning dew, and the sun is not yet at its peak, which reduces stress on the grass and mower.

Can I mow the lawn in the afternoon?

Yes, you can mow the lawn in the afternoon; however, it is generally recommended to avoid mowing during the hottest hours of the day, typically between 12:00 pm and 3:00 pm. Mowing during these hours can put extra stress on the grass and make it more susceptible to damage.

Is it okay to mow the lawn in the evening?

Mowing the lawn in the evening can be suitable, especially during the summer months when the temperature is cooler. However, ensure that you have enough daylight left to complete the task. Mowing in the evening should be done at least two hours before sunset to allow the grass enough time to recover before nightfall.

Should I consider weather conditions before mowing?

Yes, it is important to consider weather conditions before mowing the lawn. Avoid mowing if the grass is wet from rain or dew, as this can lead to clumping of the cut grass and put extra strain on the mower. Additionally, it’s best to avoid mowing on extremely hot or windy days, as these conditions can stress both the grass and the person doing the mowing.

How often should I mow the lawn?

The frequency of mowing will depend on the growth rate of the grass, which can vary depending on factors such as weather, season, and type of grass. In general, it is recommended to mow the lawn once a week during the peak growing season. However, if the grass is growing rapidly, you may need to mow more frequently to maintain an optimal height.

Final Thoughts

The best time to start mowing the lawn is in the morning or late afternoon when the temperature is cooler. This helps prevent stress on the grass and reduces the risk of dehydration. Mowing during the heat of the day can cause damage to the grass and increase the chances of heat stress. It is also important to avoid mowing wet grass as this can lead to clumping and uneven cutting. By following these guidelines and choosing the best time to start mowing the lawn, you can maintain a healthy and vibrant yard throughout the year.
