Mowing the lawn is a highly polluting activity, contributing up to 5% of the United States' total air pollution. This is due to the emissions from gas-powered lawnmowers, as well as leaf blowers and edgers. To reduce grass pollution, people can switch to using a scythe, an emissions-free alternative, or mow their lawn less frequently, allowing the grass to grow longer. Longer grass improves the health of the lawn, as it increases moisture retention in the soil and reduces the need for irrigation. Mowing the lawn after 7 pm can also reduce pollution, as it gives ozone-forming chemicals a chance to dissipate overnight.

What You'll Learn
Mowing less often
If you are using a gas-powered lawnmower, you can reduce the amount of pollution you create by mowing less often. Gas-powered lawnmowers consume a considerable amount of gasoline and spew out emissions that account for up to 5% of the United States' total air pollution. Mowing less often will reduce the amount of gasoline you use and the amount of pollution you create.
If you are unable to switch to an electric lawnmower, you can still make a difference by reducing how often you mow. 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, meaning you will need less water to maintain your lawn. Longer grass also has deeper roots, which will make your lawn more drought- and disease-resistant, provide natural weed control, and further reduce the amount of water you need to keep your lawn healthy.
You can also reduce pollution by mowing at the right time of day. Ground-level ozone is formed when VOCs and NOx combine with sunlight. If you mow your lawn 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 the air quality is bad, skip mowing altogether.
If you are looking for an emissions-free way to mow your lawn, you could try using a scythe. Scythes were used extensively in Europe and North America until the beginning of the 20th century and have been experiencing a revival recently. They are suitable for hilly and rocky terrain and can cut very tall grass that isn't suitable for gas or push mowers.

Mowing in the evening
Mowing the lawn is a chore that can be harmful to the environment. Gas-powered mowers can emit harmful pollutants into the air, contributing to air pollution and climate change.
One way to reduce grass pollution from lawn mowing is to mow in the evening. Mowing after 7 pm gives ozone-forming chemicals a chance to dissipate overnight. As the sun sets, reduced daylight makes ozone formation more difficult. Evening winds can also help disperse ozone and reduce pollution levels for the following morning.
If you usually mow your lawn once a week, consider reducing this to once every two weeks. This will improve the health of your lawn as longer grass blades improve overall moisture retention in the soil, reducing the amount of water needed to maintain your lawn.
If you are unable to mow in the evening, another option is to use a scythe. Scythes are emissions-free and suitable for hilly or rocky terrain. They can also cut very tall grass that may not be suitable for gas or push mowers.

Using a scythe
One way to stop grass pollution from lawn mowing is to use a scythe. A scythe is a curved blade attached to a long handle that is commonly used to cut grass, wheat, and other crops. Scythes were used extensively in Europe and North America until the beginning of the 20th century and have been experiencing a revival recently in certain places.
The ideal time to mow with a scythe is early in the morning when the lawn is covered with dew. The blade needs to be sharpened and then honed with a whetstone. Mowing with a scythe is emissions-free. Scythes are suitable for hilly and rocky terrain, and they can cut very tall grass that isn’t suitable for gas or push mowers.

Using an electric mower
One way to stop grass pollution from lawn mowing is to use an electric mower. Electric mowers are more environmentally friendly than gas-powered mowers, which consume a considerable amount of gasoline and spew out emissions that contribute to air pollution.
If an electric mower is not accessible, there are other ways to reduce grass pollution. 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 moisture retention in the soil, reducing the amount of water needed. You can also mow your lawn after 7 pm, as this gives ozone-forming chemicals a chance to dissipate overnight and makes ozone formation more difficult.
Another option is to use a scythe, a curved blade attached to a long handle, to cut your grass. Scythes are emissions-free and are suitable for hilly and rocky terrain, as well as for cutting very tall grass that isn't suitable for gas or push mowers.

If you can't stop mowing your lawn, there are other ways to reduce grass pollution. One way is to mow your lawn less often. For example, you could go from mowing once a week to once every two weeks. You could also mow your lawn after 7 pm, as this gives ozone-forming chemicals a chance to dissipate overnight.

Frequently asked questions
Mowing the lawn less frequently will reduce the release of pollutants over time. You can also mow your lawn after 7 pm, when it is more difficult for ground-level ozone to form, or use a scythe instead of a gas-powered mower.
You can reduce the frequency of mowing your lawn from once a week to once every two weeks. This will improve the health of your lawn, as long grass blades improve overall moisture retention of the soil, and will thus reduce the amount of water needed to maintain the lawn.
The taller your grass, the healthier your lawn. Mowing your lawn at a higher height will give your grass added root mass, making it more drought- and disease-resistant, providing natural weed control, and reducing the amount of water you need to keep your lawn healthy.
