Home Remedies for Lawn Moss

Updated February 21, 2017

A lush lawn is every homeowner's dream, but sometimes grass is susceptible to lawn moss. Lawn moss takes advantage of bare areas. It does not kill existing grass, but lawn moss is unsightly and should be removed in order for healthy grass to grow in those areas. Using bleach as a home remedy is not recommended. Even though bleach will not hurt the soil, it can cause damage and even kill plants that are close to the lawn moss.

Baking Soda

Baking soda is not harmful to the rest of your lawn and plants, but it will cause lawn moss to turn brown and die within a week. Finding the right amount of baking soda and reapplying may be necessary, especially if the lawn moss has had a chance to establish for a long period of time. Start by sprinkling regular household baking soda directly on the lawn moss, either right out of the container or out of a powdered-sugar shaker. If lawn moss seems stubborn, mix baking soda and a couple of drops of vinegar with water. Pour the mixture into a spray bottle and directly spray onto lawn moss. You can use the same baking soda mixture in a backpack lawn sprayer if you have a large section of a lawn that needs to be treated.


Dethatch or rake out dead moss that has been treated with baking soda. Vigorously dethatch or rake spots that have lawn moss that has not died yet. You can even dig out lawn moss, but it will leave larger spots in the ground that will need to be filled with soil.

Adding Lime

Check pH levels of your lawn frequently. If the pH level gets below 6 to 6.5, your soil becomes acidic and can take away nutrients from grass, causing grass to become weak. Weak grass cannot grow thick and lush, thus causing lawn moss to take over instead. Adjusting soil pH with agricultural or dolomitic lime can improve availability of nutrients and supply calcium, thus helping the grass grow better and thicker. A 10,000 sq. ft. lawn needs about ten forty-pound bags of lime per year. Apply 9.07 to 13.6kg per thousand square feet if lime has not been used for a long time.

Adding Sunlight

Lawn moss is caused by a lack of sunlight falling onto your grass, so the best home remedy is to add more sunlight by cutting off obstructing limbs. Trim the bottoms of your trees and remove any dead limbs or selected branches that could be blocking off sunlight. Concentrate on the area that has the most lawn moss and remove any branches that could be blocking out the sun from that area.

Grass Seeding

Bare areas of your lawn will grow new moss, so it is important to reseed the bare spots. Overseed bare areas with a mixture of turf-type ryegrasses and fescue blend. A mixture of grass types (perennial ryegrass, fescue, bluegrass) is more resistant to weeds and pests. Overseeding will help grow thicker grass that will block lawn moss from forming. Topdress seeds with about l/4 inch of loose weed-free soil, potting mix or sand. Topdressing improves the condition of the soil and it also adds better ground contact for seeds. Seedlings should be watered well and daily, keeping the area moist until new grass is established.
