Treating Moss Organically

Posted on by Urban Eden Landscaping

Moss thrives in damp conditions and that is one reason why it is so prevalent in Camas, Washougal, and Vancouver, Washington. However, dampness is not the only condition that can cause moss. Moss can also be caused by infertile or acidic soil, too much shade or too little water. In another article, we will discuss what causes moss to grow. For now, in this article, we will discuss treating moss organically.

Treating Moss on Hardscapes

There are several methods for treating moss on hardscapes, such as walkways, driveways, and patios. These methods will differ slightly from treating moss in lawns, which will be discussed below. First, let’s look at some organic methods for treating moss on hardscapes.

Pressure Washing

Perhaps the simplest method for treating moss on hardscapes is pressure washing. Using a pressure washer to remove moss is incredibly effective, but it does have its downsides. Pressure washing will immediately remove moss and restore the look of your hardscapes. This method is ideal for areas such as concrete driveways. Some downsides to using a pressure washer is that it uses a lot of water and, if you pressure wash paver walkways, you should anticipate replacing the joint sand between the pavers as well.

Baking Soda

As state above, moss grows in acidic conditions, so it makes sense that by increasing alkalinity, you will stave off the growth of moss. One way to remove moss from hardscapes organically is to sprinkle baking soda over the affected areas. Let the baking soda sit overnight and, afterward, use a broom to sweep up moss and baking soda. Spray the area down with a garden hose to remove any residue that may remain.

Boiling Water

As we have noted before in our blogs, using boiling water to kill weeds is a common organic practice. Boiling water can also be used to treat moss. Simply boil a pot of water and pour it onto the affected areas. Please note that, while using boiling water to kill moss or weeds is incredibly effective, it can also harm other desirable plants. Therefore, it is best to use caution when applying boiling water to undesirable plants, ensuring you do not splash or overspray onto desirable ones.


Similar to boiling water, vinegar can be used to kill weeds and moss as well. White vinegar is rated by its acetic acid level, the type typically sold in grocery stores is rated at roughly 5%, whereas the industrial strength will be rated closer to 20%. While both can be used to treat moss, the industrial strength version will be more effective. Please note that the industrial strength version can harm your eyes or lungs, so it is important to wear the proper personal protection equipment (PPE). To treat moss, pour vinegar into a spray bottle and spray directly onto the moss, being sure not to spray desirable plants as the vinegar does not discriminate. Let the vinegar sit for about 30 minutes before sweeping the moss.

Treating Moss in Lawns

As we stated above, treating moss in lawns will be a different process than removing it from hardscapes. Here are a few ways to treat moss in your lawn.


For small amounts of moss growing in your lawn, you can simply use a standard rake. Rake the moss from the lawn and then rake the moss into a pile and remove it from the property. It’s a simple but effective process for a small amount of moss.


As we have mentioned before in our blogs, dethatching has many benefits. One of those benefits is moss removal. Dethatching removes excess thatch from your lawn. Similarly, it also pulls up moss from your yard as well. You can use a manual thatch rake for smaller areas, or you can use a “power rake” (aka dethatcher) for larger areas. A dethatcher is used much in the same way as a lawn mower. Drive the dethatcher throughout your lawn and then rake the thatch and moss into piles, before removing it completely from your lawn areas.

Baking Soda

Baking soda can also be used to remove moss from your lawn. To treat moss with baking soda, mix roughly 8 ounces into a gallon of luke warm water. Pour the mixture into a standard garden sprayer and spray the moss liberally. Allow the mixture to sit on the moss overnight. By the next day, the moss should be discolored and easily raked out of the lawn.

Improving Lawn Conditions

The methods listed above are incredibly effective at treating moss growing in lawns or on hardscapes. However, of the root cause of the problem is not remedied, the moss will eventually return. In a future article we will discuss how to improve these areas so that moss does not return. For now, remember that most mosses do not thrive in sunny conditions, so improving the amount of sunlight these areas receive will drastically diminish the amount of moss in these areas.
