What You'll Learn

Pick mushrooms by hand and dispose of them
Mushrooms in your backyard can be unsightly and, more importantly, they can be dangerous if consumed by children or pets. While mushrooms are a sign of a healthy yard, it is understandable that you may want to get rid of them.
One way to do this is to pick mushrooms by hand and dispose of them. This is a natural, chemical-free way to remove mushrooms from your backyard. It is important to wear gloves when picking mushrooms to avoid touching them, as some mushrooms can be poisonous. You should also put the mushrooms you pick into a sealed plastic bag to prevent the spores from becoming airborne. You can then throw the bag into a bin.
To prevent mushrooms from growing back, you can apply a natural fungicide to the area where the mushrooms were growing. One way to make a natural fungicide is to mix 5 tablespoons of vinegar into 1 gallon of water and pour it onto the affected area. Alternatively, you can add a few drops of dish soap to the water instead of vinegar. However, it is important to keep pets and children away from the area when using these methods, as vinegar can kill grass and plants, and you should not let your pets consume dish soap.
Another way to prevent mushrooms from growing is to ensure that your yard is well-lit and free of standing water. Mushrooms thrive in damp, dark places, so improving drainage and reducing shady spots can help deter mushrooms from growing. You can do this by aerating your lawn and trimming trees and bushes.

Mow over them with a lawnmower
Mushrooms in your backyard can be unsightly, and you may worry about curious children or pets consuming them. Mushrooms are the above-ground fruit of fungi, which can be beneficial to your lawn as they break down organic matter and deposit nutrients into the soil. However, if you want to get rid of them, one way is to mow over them with a lawnmower.
Mowing over mushrooms is a quick and easy way to remove them from your lawn. It is safe to simply mow over the mushrooms and mulch them back into the ground, as the underground part of the fungus is good for your yard. Make sure to mow over the entire area where mushrooms are growing to prevent them from releasing spores and growing new mushrooms.
If you choose to mow over mushrooms, it is important to pick up the mushroom pieces immediately and discard them into a plastic bag. Seal the bag tightly before disposing of it in the trash. Do not dispose of the mushrooms with your grass clippings or other lawn waste, as this can provide an ideal environment for fungi to thrive and amplify the problem.
To prevent mushrooms from growing back, you can apply hydrated lime to the affected areas of your yard. This will fill in any areas where spores may mature into fruiting bodies. Additionally, improving drainage and airflow in your lawn by aerating the soil and reducing shady spots can make your yard less attractive to mushrooms.
While mowing over mushrooms is an effective method for removing them, it is important to note that it may not prevent future growth. Mushrooms can be persistent and challenging to eliminate completely. Therefore, combining multiple methods, such as mowing and applying lime, may be necessary for long-term prevention.

Use a commercial fungicide
Mushrooms in your backyard can be a cause for concern, especially if you have children or pets that may accidentally ingest them. While mushrooms are a sign of good soil quality, they can be harmful and are therefore best removed.
One way to get rid of mushrooms is to use a commercial fungicide. However, it is important to note that fungicides only kill the fruiting part of the fungi, so it is more effective to take preventative measures. If you do opt for a fungicide, choose one that is specifically formulated to control mushroom growth. Apply the fungicide to a dry surface after watering your lawn deeply. Follow the manufacturer's instructions carefully, as fungi can develop a tolerance to certain fungicides over time.
Fungicides are not always the best solution, as they can ruin your soil biota and kill your grass. Additionally, some people prefer not to use strong fungicide chemicals. If you are concerned about the potential impact on your soil and grass, there are DIY mixtures you can try, such as those containing soap, water, vinegar, or baking soda.
Before using a commercial fungicide, consider trying some simple methods to prevent and remove mushrooms. For example, you can improve your yard's drainage and sunlight exposure, remove decaying organic matter, or simply pick the mushrooms off the ground and dispose of them in a sealed bag in an outside garbage bin.

Prevent mushrooms by maintaining your lawn
Mushrooms in your backyard can be unsightly and even dangerous, especially if you have pets or children. While mushrooms are a sign of a healthy yard with fertile soil, they can also be poisonous.
Preventing mushrooms from growing in the first place is the best way to keep your lawn mushroom-free. Mushrooms need three things to prosper: warmth, moisture, and organic matter. Therefore, maintaining your lawn all year round for healthy grass is the key to preventing mushrooms from taking over your backyard. Here are some tips to help you maintain your lawn and keep it mushroom-free:
- Improve drainage and air circulation: Aerate your lawn to improve drainage and increase oxygen levels in the soil. This will help reduce the moisture that mushrooms need to thrive.
- Reduce shady spots: Mushrooms prefer shade or darkness, so trim trees and bushes and mow more often to let additional sunlight through.
- Keep your lawn clean: Regularly rake up and remove dead tree roots, old mulch, decaying leaves, grass clippings, wood, and pet waste. These provide the organic matter that mushrooms feed on.
- Improve the soil: If your soil retains too much water, work in some high-quality compost. Compost will help with water absorption and improve soil health.
- Water smarter: Mushrooms thrive in moist environments, so avoid over-watering your lawn.
- Dethatch your lawn: Mushrooms love to grow in thick thatch, so dethatching your yard can help prevent mushrooms from taking hold.
- Use natural deterrents: Sprinkling coffee grounds around the affected area can change the pH of the soil and make it inhospitable for mushrooms.
By following these tips and maintaining a healthy, well-maintained lawn, you can help prevent mushrooms from taking over your backyard.

Improve drainage and reduce shade
Mushrooms thrive in damp, dark environments, so improving drainage and reducing shade can help to prevent their growth.
To improve drainage, aerate your lawn to allow better air circulation and water absorption. You can do this manually with a core aerator tool or by using a Yard Butler tool, which you can buy or rent. This tool pulls narrow, cylindrical plugs of soil out of the grass every couple of inches. You can also harvest rainwater by creating a rain garden, installing rain barrels, or building a French drain for more severe cases of flooding.
Reducing shade in your yard will also help to deter mushrooms. Trim trees and bushes, and mow the lawn more often to let more sunlight through. Remove any dead branches, which can provide the dampness necessary for fungi growth. Thin out denser crowns of trees and shrubs to allow sunlight to reach the ground.
