Stop Lawn Fungus From Growing in Your Lawn (4 Easy Steps)

Mushrooms dont look great in a lawn, but they arent usually problematic or dangerous. They are actually a sign of fungi doing their job to provide nutrients to the soil.

Like most things in nature, they exist to help achieve a balance, and if you accept that this is part of your soil achieving that balance, you might start to like them.

As long as you arent worried about pets and kids getting into them, then its okay to leave mushrooms where they are in your yard.

Theyre actually quite harmless and mostly just a sign of good soil health, so long as the grass isnt dying.

Grass dying and turning brown would indicate that the hyphae mat has grown too thick, and you should probably do something.

Reducing The Emergence Of Mushrooms And Toadstools In Your Lawn

Eradicating the fungal structures completely from your lawn is generally not feasible but you can make the lawn an unattractive place for fungi to grow.

Here is a list of hints that will help with your mushroom problems.

1. Decrease shade in problem areas

If you regularly find mushrooms growing in certain areas of your lawn, then check to see if they are overly shady.

Sunshine helps control mushrooms and toadstools, as they much prefer to grow in the shade.

Trim back trees or shrubs that are overhanging the lawn, or thin out the branches to allow more sunlight through, this will also allow more air to circulate in problem areas.

2. Aerate to improve soil drainage

If your lawn often has standing water or remains damp after rain your soil might be compacted.

Compacted soil can cause moisture build-up in your lawn, leading to the damp, sodden conditions that is ideal for mushrooms growth.

Aerating your lawn will improve drainage problems, allow more oxygen to get to the roots of the grass and decrease the moisture that mushrooms thrive in.

Not sure how to go about aerating your lawn, see our article When should I aerate my lawn?

3. Dont overwater

While new lawns need plenty of water to help them get established, older lawns dont need to become sodden and drenched regularly.

Excessive watering can encourage mushroom and toadstool growth, particularly if you water late in the evening and allow the water to sit on the grass all night.

4. Remove grass clippings from your lawn

How To Get Rid Of Mushrooms In Yard Areas With Patience

Mushrooms are harmless but can be frustrating to a homeowner wondering how to get rid of mushrooms in yard areas where he or she has spent time and energy cultivating a beautiful lawn.

  • let your lawn dry out before you water it,
  • ensure that there is adequate drainage and airflow, and
  • remove organic debris and waste that acts as a food source for fungi.

When fungi spores migrate from one spot to another, they can make a bad problem worse. Innocent activities such as mowing or walking across your lawn can spread the spores far and wide, resulting in a fairy ring infestation in your yard.

Be extra careful when handling mushroom. Do not mow them down instead, pluck them out by hand or dig them out using a garden spade. Dispose of mushrooms in a plastic bag as soon as you dig them out.

You should also avoid walking over the fungi as your footsteps can also spread the spores to other parts of the lawn. Cover your shoes with a plastic bag, and remove and dispose of the bag before stepping elsewhere in the garden or surrounding areas.

What Causes Mushrooms To Grow In Lawn

Mushrooms are the reproductive organs of fungi. Fungi need a dark, moist place to grow.

Fungi need water, food and the proper temperature to grow. When these conditions exist, mushrooms will begin to appear in your lawn.

Areas that are shaded and damp are ideal conditions for mushrooms to grow in. Mushrooms can be found in lawns after it rains or when the grass is watered.

Natural Ways How To Get Rid Of Mushrooms In Lawn

The most natural way to get rid of mushrooms in your yard is to allow them to dissipate by seeing out their own life cycle.

Since mushrooms grow in organic matter that is decaying and breaking down, once this process is complete, the mushrooms will naturally die off and disappear. You can help this process along by removing any obvious sources of decaying matter, such as old rotten stumps, tree branches, animal waste, and grass clippings and thatch regularly with a thatching rake.


Another natural way to kill off mushrooms in your yard is to use vinegar. Household vinegar or cooking vinegar is usually far too diluted to do the trick, so you will need to find horticultural vinegar, which tends to be very potent.

Follow the directions on the bottle to dilute the horticultural vinegar to the right strength. You can put it in a spray bottle for ease of use. You will probably want to wear eye protection and gloves because vinegar at this strength can burn skin.

Simply spraying the mushrooms with the vinegar solution will kill them. It may also kill surrounding grass, so spray carefully. You may want to do a test area and leave it for a few days to check the effect.

Baking Soda

For a more gentle approach to removing mushrooms, try baking soda. Baking soda is not a fungicide, however, it will help to mitigate the problem by raising the pH of the soil inhibiting the mushrooms growth. It is not a permanent solution, but it is gentle, safe, and effective.

How To Stop Lawn Fungus

Lawns tend to become infected with fungal diseases when they are weak from improper care or weather conditions. It is more effective to properly care for your lawn all the time than to treat fungal problems after they arise. Irrigation timing, fertilizer and lawn maintenance affect how susceptible lawns are to fungi, although fungicides can also be helpful for certain severe fungus outbreaks. A lawn that is too moist or too dry will be most susceptible to fungus problems.


Water the lawn in the morning rather than during the afternoon or at night. Watering during the middle of day is inefficient because the afternoon sun causes a large percentage of the water to evaporate before it reaches plant roots. Watering at night contributes to fungal diseases, because the lawn stays wet overnight. It is better to water the lawn deeply and relatively infrequently than to water it lightly and frequently.


Mow the lawn when it is dry to prevent fungal spores from spreading across the lawn. Mow the lawn to the recommended height for the specific variety of grass, and do not cut it too short. Different grass species do best at different heights, and grass should be kept longest during summer. For example, most rye grasses and fine fescues should be cut to 2 to 2.5 inches during fall and spring and 2.5 to 3 inches during summer. Fine fescues grow well in urban California landscapes.

Identify Where Mushrooms Might Grow In Your Lawn

How to kill these mushrooms? [Georgia, USA] : lawncare

The first step is to determine the main cause for the mushrooms growing, whether it is in an isolated area of the garden or covering the entire length of lawn. The ideal growing conditions for mushrooms are normally moist, humid and shady.

Mushrooms are actually the fruiting bodies of fungi that produce and spread spores to create new mushrooms, with rooting systems called mycelia which exist underground, with the ability to grow up to half a mile per day. Many believe that the presence of mushrooms in their lawns is a sign of bad health, however it actually means the opposite as they are unable to grow in unhealthy, nutrient deprived soil.

Knowing why mushrooms are growing in a lawn is the key to preventing it.

Fungi grows in criss-cross formations both below the soil and across its surface, consuming decaying organic waste material such as fallen leaves, twigs, old grass cuttings, animal waste, buried wood, tree stumps and dead or dying tree roots. By recycling this organic matter, the fungi releases essential and beneficial nutrients into the soil assisting in other plant growth.

If there is excess moisture in the soil either caused by over-irrigation or poor drainage, especially with areas covered in shade, mushrooms will be able to thrive as these are perfect conditions for them to grow. The more food sources available to the fungi , the larger they will grow.

Natural Remedies For Lawn Fungus

There are many natural remedies for lawn fungus. These include baking soda solutions, neem oil, and compost teas. For the best results, you should use these natural options early in the season as a preventative rather than waiting to treat your lawn after you already have a fungus.

Neem Oil

This is one of the better natural solutions available. Dilute 2 oz of neem oil into 1 gallon of water. Apply 2.5 gallons of the spray solution per 1,000 sq ft. You will typically need to apply this solution two or three times on a 7 14 day interval to ensure effective control.

Baking Soda

Using a weak baking soda solution to treat lawn fungus issues can be effective but you must be cautious. Baking soda is a salt and like all salts, can damage your lawn.

Grass type and environmental conditions such as rainfall, air temperature and lawn stress all affect how your grass reacts to the baking soda, so you run the risk of doing more harm than good.

Compost Tea

While the use of compost teas are generally considered a good way to increase the organic content of your lawn, research on using them as a natural fungicide is limited. When applied in the spring, compost teas will help to boost the overall health of your lawn and can help your lawn to be less susceptible to getting a fungus in late spring or summer.

However, compost teas alone are usually insufficient in preventing turfgrass diseases.

    How To Kill Mushrooms Using Fungicide

    The mushrooms you see in your yard are like the fruit to the body of fungi growing under the soil. Because of this, spraying fungicide onto the mushrooms itself, probably wont kill the mushrooms directly. However, it can be used to kill the fungi growing beneath the soil.


    There are a number of garden fungicides for purchase that can be used to treat your lawn or yard. These should be used with caution on yards where children and pets play. You can purchase sprayer attachments that fit onto your garden hose allowing you to spray the affected areas. Alternatively, you can dilute the product with water and use a backpack sprayer or pump sprayer, and finally, a granular product is also available that you can sprinkle or broadcast across your lawn surface.

    Over time, you should see the mushrooms diminish. This may not be a permanent solution, so you will need to use additional measures to prevent the mushrooms from returning.

    Pick and dispose of any visible mushrooms so they do not spread spores and clean your lawn areas of any decaying matter that could contribute to mushroom growth.

    If the household products do not take care of the problem effectively, you can hire a professional to use more potent products on your lawn.
