Mushrooms in your lawn can be unsightly, and while they usually don't indicate a severe problem with your yard, you may want to get rid of them. It's important to note that the mushrooms themselves are just the flowers, and the majority of the fungus is underground, so killing them may also kill the grass. However, there are natural ways to get rid of mushrooms without resorting to harmful chemicals. These include using natural fungicides like baking soda, horticultural vinegar, or neem oil, improving drainage, removing decaying organic matter, and regular lawn care practices such as mowing, dethatching, and aerating. Additionally, you can pick the mushrooms by hand or use a mild fungicide made from dish soap and water.

What You'll Learn
Use natural fungicides like baking soda, vinegar, or neem oil
Mushrooms in your lawn can be an eyesore and may even be harmful. While they indicate that your soil is rich and of good quality, they can also be dangerous to pets and children. Mushrooms are a part of the fungi family, and their presence means that there is a healthy biological activity in the soil. Fungi play a role in decomposing organic debris and recycling nutrients such as nitrogen, phosphorus, and potassium back into the soil.
To kill lawn mushrooms naturally, you can use natural fungicides like baking soda, vinegar, or neem oil. Here's how you can use these natural fungicides effectively:
Baking Soda
Baking soda can be used to raise the pH of the soil, creating an environment that is less conducive to mushroom growth. To use this method, dissolve 2 tablespoons of baking soda in a gallon of water. Ensure that you aerate the soil well around the mushrooms before applying the solution. Pour the baking soda water around and over the mushrooms, allowing the water to drain freely into the soil. Be cautious when using baking soda, as too much can raise the pH of the soil to a level that is unsuitable for grass growth.
Vinegar
Vinegar is another natural fungicide that can be used to kill lawn mushrooms. Its acetic acid content will effectively kill the mushrooms. To use vinegar, mix one part vinegar with four parts water in a spray bottle. Apply this solution directly to the infected areas, especially as a spot treatment for persistent mushrooms. However, exercise caution when using vinegar, as it will also injure grass and other plants if applied too heavily.
Neem Oil
Neem oil is often used to get rid of bugs and insects in lawns. While there is no direct evidence that it kills mushrooms, some people believe it may help. If you're considering using neem oil, consult a professional or seek advice from online forums dedicated to lawn care or mycology.
While using natural fungicides can be effective, it's important to remember that they may not completely eliminate the mushrooms. The mushrooms you see are just the "flowers," with the majority of the fungus underground. Additionally, some sources suggest that improving drainage, reducing shade, and removing organic matter can help prevent mushrooms from growing in your lawn. Manual removal by hand-picking mushrooms is also an option, but it can be tedious and may not address the underlying fungal issue.

Improve lawn drainage and avoid overwatering
Mushrooms thrive in moist, shaded areas with organic material. They are a sign of rich and fertile soil, which is beneficial for your lawn and garden. However, they can be unsightly and may indicate overwatering.
To prevent and eliminate mushrooms, it is crucial to address the moisture content in your lawn. Here are some detailed steps to improve lawn drainage and avoid overwatering:
Improve Lawn Drainage
- Aerate your lawn: Aeration involves creating small holes in the lawn to allow better air circulation and drainage. You can use a tool like the Yard Butler, which pulls narrow, cylindrical plugs of soil out of the grass every couple of inches.
- Fix poorly draining spots: Identify areas in your yard that tend to retain water and take steps to improve drainage. This may involve levelling the ground, adding drainage pipes, or incorporating sand or other porous materials to enhance water absorption.
- Mow and dethatch regularly: Mowing your lawn more frequently helps keep the grass short, allowing it to dry out more quickly. Dethatching removes the thick layer of thatch, which can retain moisture and provide an ideal environment for mushrooms.
- Remove decaying organic matter: Leaves, grass clippings, and other organic debris can contribute to moisture retention and provide food for mushrooms. Rake and remove this debris to improve drainage and reduce mushroom growth.
Avoid Overwatering
- Optimize your watering schedule: Water your lawn deeply but less frequently. Instead of watering daily, aim for once or twice a week, providing enough water to reach the roots. This promotes deeper root growth and reduces waterlogging.
- Repair watering equipment: Check for any broken sprinkler nozzles or leaky hoses and repair or replace them. This ensures that water is distributed evenly and efficiently, reducing the risk of overwatering in certain areas.
- Avoid watering at night: If you have a history of mushroom problems, avoid watering your lawn at night. Instead, water in the early morning to give the grass time to dry during the day.
By following these steps, you can improve lawn drainage and avoid creating the moist conditions that mushrooms favour. Remember that mushrooms are a natural part of the soil ecosystem, and while they may be unsightly, they often disappear on their own once the soil dries out.

Remove decaying organic matter
Mushrooms are considered unsightly, especially if you are preparing to sell your property. Some mushrooms are edible, while others are toxic, which can be dangerous if young children and pets play on your lawn. Mushrooms thrive in damp, shaded areas, springing up from fungi and feasting on organic matter. They grow in a circle around a decaying source of organic matter, such as a tree stump. The fungi spread out from the food source in circular waves, creating distinctive "fairy rings".
To prevent mushrooms from growing, it is essential to remove decaying organic matter from your lawn. This includes clearing away dead leaves, tree branches, animal waste, bark, and grass clippings. Thatch, a matted layer of dead organic matter, can also provide an ideal environment for mushrooms to flourish. By removing thatch through raking or using specialized tools, you can reduce the areas where mushrooms can grow and improve the aesthetics of your yard.
Additionally, it is crucial to address conditions that favor mushroom growth, such as poor drainage, shady spots, and overgrown trees. Mushrooms thrive in damp conditions, so improving drainage and reducing standing water can help deter their growth. Removing old tree stumps and trimming back bushes and tree limbs will increase sunlight exposure, making the environment less favorable for mushrooms.
While removing decaying organic matter is a crucial step in preventing mushroom growth, it is equally important to be cautious when addressing this issue. Mushrooms play an important role in the ecosystem, and their presence indicates fertile and healthy soil. Therefore, it is recommended to explore natural prevention methods before resorting to more drastic measures.
It is worth noting that some mushrooms may disappear on their own when the soil dries out or when they have exhausted the organic matter they are decomposing. Therefore, it is beneficial to adopt preventative measures, such as maintaining your lawn for healthy grass, rather than solely focusing on removing the mushrooms once they appear.

Pick mushrooms and place them in a tightly sealed plastic bag
Picking mushrooms is a simple yet effective way to keep your lawn clear of these fungi. It is a good idea to wear gloves when picking mushrooms, as some species can be toxic. Place the mushrooms in a plastic bag, seal it tightly, and dispose of it in an outdoor bin. This will prevent the mushrooms from releasing spores, which can spread and cause more mushrooms to grow.
It is important to act quickly when you spot mushrooms in your lawn. The longer you leave them, the more spores they will release, and the harder it will be to control their growth. Regularly scan your lawn for mushrooms, especially after rainy periods, as these fungi thrive in moist environments.
You can also take preventative measures to stop mushrooms from growing in the first place. Mushrooms flourish in damp, shaded areas with rich organic matter, so improving drainage and reducing shade can make your lawn less attractive to them. Aerating your lawn will improve air circulation and drainage, while mowing more regularly will help keep your grass dry, as shorter grass dries out faster than longer grass.
In addition to physical removal, you can also use natural fungicides like horticultural vinegar, baking soda, or neem oil to treat the affected areas. However, these substances should be used with caution, as they can harm surrounding plants. Always follow the manufacturer's instructions and wear protective gear when applying these treatments.
While it may be frustrating to see mushrooms popping up in your lawn, it's important to remember that they are not inherently harmful. In fact, they indicate that your soil is fertile and of good quality. Mushrooms play an important role in the ecosystem, helping to break down organic matter and release nutrients for your grass to absorb. However, if you are concerned about the appearance of your lawn, or if you have children or pets who might be at risk of ingesting toxic mushrooms, it is understandable to want to remove them.

Mow, dethatch, and aerate your lawn regularly
Mushrooms thrive in damp, dark environments, breaking down organic matter in your lawn and yard. They love patches of lawn that are dead, thick with thatch and covered in leaves. They also grow in areas with lots of soggy leaf mould, decaying tree stumps and branches.
Mowing, dethatching, and aerating your lawn regularly can reduce conditions favourable to mushrooms. Mowing more regularly is a good idea, as short grass dries out more quickly than long grass. Dethatching and aerating your lawn will improve drainage, reducing the chances of mushrooms growing.
You can rent or buy a Yard Butler tool, which pulls narrow, cylindrical plugs of soil out of the grass every couple of inches, allowing better air circulation and drainage. You can also adjust your watering schedule to water your lawn less frequently, but more deeply. This will provide moisture to the lawn without creating the damp conditions that mushrooms thrive in.
