Guide to Get Rid of Moss in Your Lawn

What is Moss?

It’s good to learn about it before you start looking for ways to kill moss in your lawn and surrounding grass.

Because moss isn’t like other weeds, standard weed killers won’t work on it.

It is a prehistoric plant that lacks genuine roots. In reality, it isn’t harmful to your grass, yet it shows your lawn is suffering.

Moss begins to show with excessive shade or soil issues such as compacted soil, low soil pH, or poor drainage.

Lawn moss thrives in these conditions, whereas your grass will suffer.

Water gathers if your lawn has a poor grade and poor drainage, or there are areas where water can pool, and from this, moss can begin to thrive.

Moss will also out-compete grass for nutrients if you don’t feed your lawn to maintain healthy grass that can block out weeds or moss.

Moss grows in the shade, so if your lawn has plenty from surrounding trees, this can keep your lawn damp enough to offer moss the ideal growing conditions.

Moss shows itself in mild climates that receive plenty of rain. Unfortunately, there won’t be too much any gardener can do but try to control moss in such conditions.

How To Prevent Moss

Make your lawn less inviting to moss if you want to keep it from taking up home. The most effective strategy is to address the factors that may have caused moss.

Too Much Shade

The amount of sun your lawn needs varies depending on your location and grass variety. Most lawns need 4-6 hours of sunlight every day on average.

Pruning back branches that create a shadow over a significant section of your lawn is a good idea. You might also cultivate tall fescue, a grass type that does well in the shade.

Soil pH is too low.

You can send a soil sample for testing or purchase a home test kit to see if it contains the nutrients and has the proper alkaline levels.

The pH level of a lawn should be between 6.0 and 7.0. if it is out of this, you can start adding lime to make the lawn less acidic. A healthy lawn requires soil amendments and fertilizer regularly. (Read Does Roundup Kill Moss)

Soil drainage is poor.

Your soil can face drainage issues if it absorbs too much moisture. Conversely, moss thrives in lawns with poor drainage.

The type of soil you have affects whether you will face drainage problems such as clay soil that leads to puddles. Luckily, some lawn care can stop such drainage issues from being too much of an issue.

Soil that has been compacted.

Excessive foot traffic and thatch lead to compacted soil. Soil like this makes it challenging for soil to receive a consistent supply of nutrients, water, and oxygen.

Aerating your lawn is a quick fix for this, and it can also help with soil drainage.

Dethatching your lawn also helps in several areas of lawn care.

Prevent Moss with Treatment

How Do I Prevent Moss?

Use a composite lawn feed that contains nitrogen, phosphate, and potassium to feed your lawn (NPK).

If you prefer to go organic, a handful of bone meal per square yard can be applied in the early fall, a great source of phosphorus.

After every other lawnmower run, apply well-rotted crumbly leaf compost on the lawn. Using either of these approaches, nitrogen is returned to the soil.

Scarify the lawn with a rake or an electric scarifier to remove all dead vegetation, thatch, and moss.

When To Treat Moss in Lawn?

Any treatment for how to get rid of moss on lawn is best done in the late fall, winter, or early spring, as your lawn won’t have any competition.

Here are the complete steps of how to deal with your moss issues.

How to Get Rid of Moss in Lawns

  • Mark lawn in strips
  • Mix iron sulfate using 12 heaped teaspoons per gallon of water.
  • Spray your water mixture along your strips in a windshield wiper pattern.

All the moss sprayed turns black after 20 minutes, making it easy to tell where you missed.

It will stain concrete and asphalt; therefore, consider other chemicals as a remedy to get rid of your moss species close to these areas.

Getting Rid of Moss in Your Lawn with Chemicals

Iron sulfate (seen above) and glyphosate are the two most prevalent components in moss-killing chemicals.

Iron sulfate will harm moss within hours and effectively kill it within two days. This component is ubiquitous in fertilizers and will not hurt the grass on your lawn. (Learn How To Kill A Tree Without Cutting It Down)

Glyphosate is non-selective, meaning it will kill moss and grass.

Before deciding on a strategy for treating moss in paved areas, ask yourself the following questions:

Will moss treatment discharge impact grass, other desired plants, or neighboring trees?

Is the area used by youngsters or pets?

Is it possible to prevent moss from returning by increasing sunlight or reducing moisture?

Dealing with your moss with Chemicals

Moss Killer Spray

Moss on concrete, bricks, and pavers can be killed with commercial moss killers. These are simple to apply as they don’t often need mixing with cold water. They will eliminate moss without staining concrete, damaging surrounding plants, or discoloring wood or paint.


  • Kills moss in hours.
  • Concrete, decks, paint, and siding will not be stained.
  • Will not harm grass or plants in the garden.
  • Once dry, it’s safe to use around children and animals.
  • Connect the bottle to the end of a garden hose and spray the moss. Within 3–5 hours, the moss will turn brown and die.
  • You can sweep up the dead moss with some cold water and a stiff broom.

Note: To remove moss from concrete or bricks, do not use weed killers like Roundup.

Natural Ways to Kill Moss Quickly

If you want to remove moss naturally, here are some of the best natural methods for killing moss that won’t harm garden plants if you take some care in application.


Make a moss-killing solution by mixing 0.5 cups of home bleach with 1-gallon warm water.

The bleach solution is diluted enough to be safe around plants and paved surfaces, but it’s still recommended to be cautious.

In a few hours, pour or spray the bleach solution onto the living moss to kill the moss in a few hours.

Tips for using bleach to kill moss:

  • Concrete, wood, and painted surfaces may be discolored by bleach.
  • Runoff from bleach can harm grass and other vegetation.
  • Once dry, it’s safe to be around people and animals.

Baking Soda to Kill Moss Naturally

Baking Soda

Baking soda is a quick way to deal with moss. However, it isn’t the most effective solution for a lawn with long-term or more moss growing.


  1. Add 2–3 teaspoons of baking soda to 1 quart of water, gently stir until completely dissolved, and pour into a spray bottle
  2. Apply the baking soda solution to the moss liberally on a warm, dry day when rain isn’t expected for a few days. Avoid grass and other plants.
  3. Allow 2–3 days for the moss to dry and turn golden brown.
  4. Remove the moss with a rake or a shovel and dispose of it away from your lawn.


Because it contains acetic acid, vinegar kills moss while being very cost-effective.


  1. Mix 1 gallon of cold water and 1 tablespoon of distilled white vinegar.
  2. Fill a spray bottle halfway with vinegar and water, then spray the solution straight on the moss to soak it.
  3. Continue to apply the vinegar solution every day until the moss dies. If the moss does not die after a few days, add more vinegar to the solution.
  4. Rake or dig up the moss once it has died and dispose of it.

Boiling Water

Boiling water will kill moss. All you have to do is boil some water and pour it over the moss that has grown on your concrete.

It will kill moss in a matter of hours, and the runoff will cause no harm if the boiling water isn’t dumped on any other plants.

It kills moss, yet you can’t use this method to naturally kill moss in your lawn as it has the same effect on your grass.

Dish Soap

You can apply dish soap to kill moss in your lawn safely and effectively.

  1. Combine 2 ounces of dish soap and 1-gallon water in a spray bottle. Use a light liquid dish soap that is natural and nontoxic.
  2. A 500-square-foot lawn will be treated with this amount of dish soap solution.
  3. For killing moss patches, spray the solution up close and keep away from your grass when spraying.
  4. Dig it up or rake it out once the moss has dried and become brown.
  5. Dispose of the Moss away from your lawn to avoid spores returning to their original location.

Once established in your lawn, controlling moss can seem impossible, but effective control to kill lawn moss may be more straightforward than you believe.

It involves dealing with existing lawn moss and fixing conditions that encourage its growth.

Understanding that moss isn’t like other unwanted lawn “weeds” is the first step in dealing with future lawn moss issues.

Mosses are primitive plants that do not use water and nutrients like other advanced plants.

So weed killers won’t kill mosses. Even potent herbicides designed to kill all plant types fail to kill or prevent moss plants. (Read Do Sunflower Seeds Go Bad)

Moss loves shade, acidic soil, and locations with standing water or excess moisture.

When existing moss is actively growing, treat it. This usually occurs during fall, warm winter, and early spring rains.

Lawn moss needs little light or plant to survive, but external and internal moisture need.

Fertilizer for lawn granules blends 10% iron with a nitrogen-rich 20-0-5 lawn fertilizer to quickly treat moss and feed your lawn. Using these moss killer chemicals as prescribed kills moss quickly. The increased plant nutrients also assist in thickening the grass and fighting lawn moss.

Correct the issues that allowed moss to grow on your lawn to maintain it clear of moss.

A soil test determines if the lawn needs lime to lower soil acidity and promote healthy grass growth.

Fix drainage problems and thin neighboring trees or shrubs to enable more light to reach the grass. Aeration reduces moss growth in compacted soil, and regular lawn care keeps grass healthy.

You can swiftly kill moss and preserve thick, green grass by enhancing your lawn’s conditions and treating moss effectively.
