When is it Too Cold to Mow Your Lawn in 2023?

Have you ever wondered whether it’s too cold to mow the grass while gazing out the window? Many homeowners ponder this, especially during the cooler months of the year. While some might think it’s always too cold to mow the lawn, others might think it’s fine even if snow is on the ground. So, when is it too chilly to cut the grass, then?

This article provides an answer to that query and useful advice for maintaining your grass during the winter months. However, it is important to discuss why cold should affect mowing.

Although being a homeowner requires regular lawn maintenance, which generally improves healthy growth, at the same time, it can be difficult to know what to do as the seasons change.

Understanding the Effects of Cold Weather on Grass

The grass is a resilient plant that can survive and even thrive in various temperatures. However, it’s important to comprehend how cold weather affects the grass to know when it’s safe to mow your lawn.

Cold temperatures can cause a wide range of significant issues for grass, especially if the temperature drops suddenly or stays cold for an extended period. One of the most significant issues that cold weather can cause is frost.

Frost occurs when the temperature drops below freezing, causing the moisture in the grass to freeze. When this happens, the blades of grass become brittle and can snap easily, causing damage to the grass.

Another issue that cold weather can cause is root damage. Grass roots are essential for the health and growth of the grass, and they are especially vulnerable to injury in cold weather. If the temperature drops suddenly, the grassroots can become damaged, leading to yellow or brown spots in the lawn.

In addition to frost and root damage, cold weather can also slow down the growth of grass. Grass needs warmth and sunlight to grow, and when the temperature drops, the development of the grass slows down.

This can be beneficial in some ways, as it can help the grass conserve energy during winter. However, it can also mean the grass is more vulnerable to damage if mowed during this time.

The Ideal Temperature for Mowing Grass

Mowing the lawn is necessary to maintain a beautiful and healthy yard. However, mowing your lawn at the wrong time or under nonoptimal conditions can lead to damage, stress, and even death of your grass. One important factor to consider before mowing your lawn is the temperature.

The ideal temperature for mowing grass is between 15.6 and 26.7 degrees Celsius. At this temperature range, the grass is growing actively and is strong enough to withstand the stress of mowing. Mowing during this temperature range ensures the grass recovers quickly and stays healthy.

When the temperature is too low, below 10 degrees Celsius, the grass will not grow actively, and mowing can be damaging. Mowing during this time can cause stress on the grass and lead to uneven cuts, leaving the grass susceptible to disease and pests.

On the other hand, mowing during high temperatures above 26.7 degrees Celsius can also be harmful to the grass. Mowing during this time can cause heat stress on the grass, leading to browning and even death. The hot sun and dry air can also make the cut grass dry out quickly, leading to an unsightly appearance and the need for additional watering.

When is it Too Cold to Mow the Lawn?

Mowing the lawn during colder months can be risky and could potentially damage your lawn, especially if you are unaware of the optimal temperatures for lawn mowing.

Mowing the lawn at ideal temperatures can help promote healthy growth and reduce stress on the grass. However, if, upon checking, you see that the temperature is below 10°C, it is best not to mow the lawn at that time.

Grass grows slower in colder temperatures, and mowing can damage the leaves and stunt growth, which could lead to brown patches on the lawn.

Furthermore, it is imperative to note that the soil temperature differs from the air temperature. When determining the temperature for lawn mowing, it is crucial to consider the soil temperature as well.

By mowing the lawn when the soil is too cold, you can damage the roots, making it difficult for the grasses to grow properly.

Another factor you should look into when deciding if it is too cold to mow your lawn is the kind of grass you have. For instance, warm-season grasses such as Bermuda and Zoysia grass prefer warmer temperatures and may require mowing even when the temperature is higher than 26.7°C.

As for cool-season grasses such as Kentucky bluegrass and fescue grow best in cooler temperatures and may require mowing even when the temperature is below 15.6°C.

Tips for Mowing During Cold Weather

If you must mow your lawn during very cold periods, here are some tips you can follow to make the process safer and more effective. You should keep the following in mind:

  1. Warm Up Your Mower: If it has been in cold storage for a while, it’s important to warm it up before using it. This will ensure the engine runs smoothly and the mower effectively cuts grass.
  2. Adjust the Mower Height: During colder months, you may want to adjust the height of your mower blades. This will prevent the grass from being cut too short, damaging it and making it more susceptible to disease.
  3. Use the Right Type of Fuel: During colder months, using the right fuel for your mower is essential.
  4. Check the Tires: Check the air pressure in your mower tires in cold months. Cold weather can cause tires to lose pressure, which can affect the performance of your mower. Check the pressure regularly and inflate the tires as needed.
  5. Dress Appropriately: When mowing during cold weather, it’s essential to dress appropriately. Wear thick clothes that keep you warm, including a hat and gloves, to keep yourself from the cold. You should also wear a face mask to protect yourself from the harsh cold.


Determining when it is too cold to mow the lawn is essential to maintaining a healthy and beautiful lawn. As discussed in the previous sections, mowing the lawn in extremely cold temperatures can cause significant damage, such as browning and yellowing of the grasses, making it more susceptible to diseases and pests.

It is crucial to remember that the ideal temperature for mowing the lawn is between 15.6 and 26.7 degrees Celsius. It is too cold to mow the lawn when the temperature drops below 4.4 degrees Celsius. This is because the grass goes dormant in extremely cold weather, making it harder for the lawn to recover from the stress caused by mowing.

Now that you know this, paying attention to the weather forecast and planning your lawn care in line with this is important. Caring for your lawn during the cold weather requires some knowledge and planning.

By following the guidelines in this article, you can ensure that your lawn remains healthy and beautiful all year round. So, whenever you think about mowing your lawn during winter, remember that waiting until the temperature rises above 4.4 degrees Celsius is safer.
