Mowing the lawn is a chore that many of us do without thinking about the environmental impact. However, the perfect lawn is resource-intensive and can cause a significant amount of pollution. Gas-powered lawnmowers can account for up to 5% of a country's air pollution, and that's not including leaf blowers and edgers. Luckily, there are ways to reduce the environmental impact of mowing, from switching to a scythe to simply mowing less often.

What You'll Learn
- Mowing less often can improve the health of your lawn and reduce water usage
- Mowing after 7 pm gives ozone-forming chemicals a chance to dissipate overnight
- Taller grass means healthier roots, which can make your lawn more drought- and disease-resistant
- Using a scythe instead of a mower can reduce emissions
- Electric mowers are better for the environment than gas-powered mowers
Mowing less often can improve the health of your lawn and reduce water usage
If you can't cut down on how often you mow, you could try switching to an electric mower, or mowing in the evening instead of the morning. Mowing in the morning puts ozone-forming emissions into the air during the "prime time" for ozone to form. If you mow after 7 pm, you give ozone-forming chemicals a chance to dissipate overnight. Evening winds can also disperse ozone and reduce pollution levels for the following morning. If you're feeling adventurous, you could even try mowing with a scythe, which is emissions-free.

Mowing after 7 pm gives ozone-forming chemicals a chance to dissipate overnight
Mowing the lawn is a chore that can be harmful to the environment. Gas-powered lawnmowers can account for up to 5% of the United States' total air pollution. To reduce grass pollution, it is recommended to mow your lawn after 7 pm. This gives ozone-forming chemicals a chance to dissipate overnight. Ground-level ozone is formed when VOCs and NOx combine with sunlight. Mowing your lawn in the morning puts these emissions into the air during the "prime time" for ozone to form. By waiting until after 7 pm, you reduce the amount of ozone that is formed, as there is less daylight and the evening winds can disperse ozone and reduce pollution levels for the following morning.
If you are unable to mow your lawn after 7 pm, there are other ways to reduce grass pollution. One option is to mow your lawn less frequently. Instead of mowing once a week, try mowing once every two weeks. This will improve the health of your lawn by increasing moisture retention in the soil, which will reduce the amount of water needed to maintain your lawn. Another option is to use a scythe instead of a gas-powered lawnmower. Scythes are emissions-free and are suitable for hilly or rocky terrain, as well as for cutting very tall grass.
You can also reduce grass pollution by making your lawn healthier. The taller your grass, the healthier your lawn. There is a direct correlation between the height of the grass and the depth of the roots. By allowing your grass to grow longer, you will have deeper roots that will make your lawn more drought- and disease-resistant, provide natural weed control, and reduce the amount of water needed to keep your lawn healthy.
Finally, if you are using a gas-powered lawnmower, make sure you are using an EPA-approved gas can. Older cans can cause more spillage, and harmful emissions may be escaping from holes or sprouts. By using an approved gas can, you can reduce the amount of harmful emissions released into the air.

Taller grass means healthier roots, which can make your lawn more drought- and disease-resistant
Keeping grass healthy and well-maintained is resource-intensive and requires irrigation, weeding, fertilising, and mowing. Mowing, in particular, can be a major source of pollution, with gas-powered mowers consuming a considerable amount of gasoline and spewing out emissions that account for up to 5% of the United States' total air pollution.
One way to reduce grass pollution from lawn mowing is to mow less frequently. Longer grass blades improve overall moisture retention of the soil, reducing the amount of water needed to maintain the lawn. This means that mowing can be reduced from once a week to once every two weeks, for example.
The height of the grass also has a direct correlation with the depth of the roots. Taller grass means healthier roots, which can make your lawn more drought- and disease-resistant. If you mow your lawn down to two inches, you will have two inches of roots. However, if you mow at four inches, you will have four inches of roots. That added root mass will make your lawn more resilient and reduce the amount of water you need to keep it healthy.
To reduce grass pollution, you can also consider switching to a more environmentally friendly mowing method, such as using a scythe. A scythe is a curved blade attached to a long handle that is suitable for hilly and rocky terrain and can cut very tall grass that isn't suitable for gas or push mowers. It is emissions-free and can be used successfully on sloped landscapes.
Additionally, the time of day you mow your lawn can impact pollution levels. Mowing in the morning puts ozone-forming emissions into the air during the "prime time" for ozone to form. If you mow your lawn after 7 pm, you give these chemicals a chance to dissipate overnight, and reduced daylight makes ozone formation more difficult. Evening winds can also disperse ozone and reduce pollution levels for the following morning.

Using a scythe instead of a mower can reduce emissions
Lawn mowing can be a significant source of pollution, with gas-powered mowers consuming a considerable amount of gasoline and emitting harmful pollutants into the air. To reduce emissions and grass pollution from lawn mowing, one option is to use a scythe instead of a mower.
A scythe is a curved blade attached to a long handle that is used to cut grass, wheat, and other crops. While scythes may seem like a relic of the past, they are experiencing a revival in certain places due to their emissions-free mowing capabilities. By using a scythe, you can avoid the pollution associated with gas-powered mowers, which can account for up to 5% of the United States' total air pollution.
One of the benefits of using a scythe is its suitability for hilly and rocky terrain. Scythes can also cut very tall grass that may not be suitable for gas or push mowers. Additionally, scythes do not require gasoline, eliminating the need for fuel and the associated emissions.
To use a scythe effectively, it is important to keep the blade sharpened and honed with a whetstone. The ideal time to mow with a scythe is early in the morning when the lawn is covered with dew. This helps the scythe glide through the grass more easily.
By switching from a gas-powered mower to a scythe, you can significantly reduce emissions and grass pollution from lawn mowing. This simple change can have a positive impact on the environment and contribute to a more sustainable lawn care routine.

Electric mowers are better for the environment than gas-powered mowers
In contrast, electric mowers are emissions-free. They are also more accessible and can be used on hilly and rocky terrain, as well as on very tall grass that isn't suitable for gas-powered mowers.
If an electric mower is not accessible, there are still ways to reduce pollution from lawn mowing. One way is to mow your lawn less frequently. For example, you could go from mowing once a week to once every two weeks. This will improve the health of your lawn as longer grass blades improve the overall moisture retention of the soil, reducing the amount of water needed. Another way to reduce pollution is to mow your lawn after 7 pm, as this gives ozone-forming chemicals a chance to dissipate overnight.
Overall, electric mowers are a more environmentally-friendly alternative to gas-powered mowers and can help to reduce grass pollution from lawn mowing.
