While moss isn’t actually detrimental to your grass, some homeowners may not want moss to overtake their yard. Getting rid of moss is relatively simple, but takes several steps—and discovering just why it finds your lawn so hospitable is key.
In this guide, you’ll learn what you need to know about getting rid of moss in your lawn and how to prevent moss from coming back.
What is Moss?
Moss is a flowerless, ancient plant that often grows in dense clumps or mats. It doesn’t have true roots and it isn’t actually detrimental to your grass. In fact, some people incorporate moss into their lawns on purpose.
However, the presence of moss could indicate that your lawn is struggling. Common causes for lawn moss include issues like excessive shade or soil problems—it can be compacted, have low soil pH, or poor drainage. While grasses suffer in these conditions, moss thrives. So even though moss won’t kill your grass, the conditions that support its growth can.
Getting Rid of Moss in Your Lawn Naturally
Moss isn’t like other weeds, so traditional weed killers won’t be effective against it. The most common way to get rid of moss naturally is by using dish soap. The best time to kill moss is when it’s actively growing, in late spring to early summer or late summer to early fall.

Getting Rid of Moss in Your Lawn With Chemicals
The two most common ingredients in moss-killing chemicals are iron sulfate and glyphosate. Iron sulfate will start damaging moss in a matter of hours and effectively kill it within two days. This ingredient is commonly found in fertilizers and won’t harm your lawn’s grass.
Glyphosate, on the other hand, is non-selective and will kill both the moss and grass it comes into contact with.
How To Prevent Moss
If you want to prevent moss from taking up residence, make your lawn less hospitable to the weed. The best way to do this is by resolving the issues that may have led to the moss in the first place.
Excessive Shade
The precise amount of sun your lawn needs will depend on your region and grass type. On average, most lawns need about four to six hours of sunlight per day. If branches are casting a shadow over a large area of your lawn, prune them back. You can also switch to growing a grass that tolerates shade better, like tall fescue.
Low Soil pH
Send a sample of your soil to a university or your local cooperative extension. They can test the soil to determine if it has the proper nutrients and whether it’s alkaline enough. In general, a lawn’s pH level should be between 6.0 and 7.0. To make your lawn less acidic, you can apply lime. Soil amendments and regular fertilization are the key to a healthy lawn.
Poor Drainage
Drainage issues welcome moss. The type of soil you have can impact the likelihood of drainage issues—clay soil tends to puddle. However, you can amend the soil to make it easier for moisture to pass through.
Compacted Soil
Excessive foot traffic and thatch can compact your soil, preventing it from retaining a steady flow of nutrients, water, and air. You can rectify this by aerating, using a tool or machine to poke thousands of tiny holes into your lawn to let it breathe. Dethatching, or breaking up the layer of decomposing organic matter between grass blades and the soil, will also alleviate this issue.
