Mushrooms in your lawn can be unsightly, and some varieties are poisonous, posing a risk to children and pets. However, mushrooms are a sign of healthy soil, so their presence indicates that your lawn is in good condition. If you want to get rid of mushrooms, you can simply mow over them, rake them, or pick them out by hand. To prevent mushrooms from growing, you can improve your lawn's drainage by aerating the soil, reducing the moisture that mushrooms thrive in.

What You'll Learn
Remove mushrooms by hand, with a spade or lawnmower
Mushrooms in your lawn indicate healthy soil, but they can be unsightly and dangerous if consumed by children or pets. While it is challenging to stop mushrooms from growing, there are several ways to remove them by hand, with a spade, or with a lawnmower.
Removing Mushrooms by Hand
To remove mushrooms by hand, it is recommended to wear gloves and place the mushrooms in a plastic bag to prevent spores from spreading. Pull the mushrooms from the base, ensuring you remove as much of the mushroom as possible from the ground. Cutting the mushrooms with a knife can also help to ensure you remove most of the fungus.
Removing Mushrooms with a Spade
Using a spade or shovel, dig out the mushrooms and the surrounding soil to a depth of 12 to 18 inches and about 2 feet outside of the mushroom cluster. This thorough approach ensures that you remove the entire fungus, not just the mushroom head.
Removing Mushrooms with a Lawnmower
Using a lawnmower can be an effective way to remove mushrooms and prevent their growth. First, remove any existing mushrooms by hand to prevent the spread of spores during mowing. Then, mow over the entire area infested with mushrooms. Regular mowing can help deter mushroom growth by reducing the height of the grass, allowing the soil to dry out faster.
While removing mushrooms by hand, with a spade, or with a lawnmower can be effective, it is important to remember that these methods may only provide a temporary solution. To prevent mushrooms from growing in your lawn, you must address the underlying causes, such as improving soil drainage, reducing shade, and limiting organic matter that serves as a food source for the fungi.

Improve drainage with aeration, dethatching, and French drains
Mushrooms thrive in soggy conditions caused by soil compaction or heavy soils that don't drain well. The presence of mushrooms in your lawn usually indicates that the soil underneath your grass is not draining properly.
To prevent mushrooms from growing in your lawn, you can improve drainage through aeration, dethatching, and installing French drains.
Aeration breaks up soil compaction, allowing water to penetrate the soil rather than sitting on top of it. This can be done by using a spade or a machine aerator to create holes in the lawn, which will improve water absorption and reduce soggy conditions that promote mushroom growth.
Dethatching is another effective method to improve drainage. Thatch is a buildup of living and dead grass, roots, and stems on the soil surface that limits air circulation and inhibits water movement into the soil. By scarifying the lawn with a vertical mower or using a power rake to remove the thatch, you can improve drainage and reduce the conditions that favour mushroom growth.
For more severe cases of drainage issues, you may need to consider installing French drains. French drains are professionally installed underground drainage systems that help redirect water away from your lawn, improving drainage and reducing the soggy conditions that mushrooms thrive in.
By combining these drainage improvement techniques with other methods such as removing organic matter and increasing sunlight exposure, you can effectively reduce the conditions that promote mushroom growth in your lawn.

Reduce shade with pruning
Mushrooms thrive in shady, moist conditions with high levels of nitrogen from decaying organic material. To prevent mushrooms from growing in your lawn, you can reduce the shade in problem areas by pruning.
Pruning involves trimming back or thinning out branches on nearby trees or shrubs to let in more sunlight. This helps to decrease the shade that mushrooms favour and encourages evaporation of excess moisture. When pruning, remove any dead branches, as these can provide the damp conditions necessary for fungi growth. You should also thin out denser crowns of trees and shrubs to allow more sunlight to penetrate through to the lawn.
In addition to pruning, you can improve drainage in your lawn by aerating the soil. This can be done by using a manual core aerator tool or a thatch rake to punch tiny holes into the ground, allowing air and water to circulate better. Aeration helps to create a drier environment that is less favourable for mushroom growth.
By reducing the shade and improving drainage through pruning and aeration, you can help to create conditions that are less conducive to mushroom growth in your lawn.

Avoid overwatering and organic mulches
Mushrooms thrive in moist, dark environments. They are a sign of overwatering and can be prevented by improving the drainage of your lawn. To do this, you can aerate your lawn, which creates holes in the soil to allow better air circulation and drainage. This can be done by renting or purchasing a Yard Butler tool or an aerator. Additionally, you can address underlying issues such as clogged gutters, flat yards, impacted soil, or sidewalks that block water drainage.
To prevent mushrooms, it is important to keep your lawn dry and reduce the amount of organic matter present. Avoid mulching, composting, or fertilizing your lawn excessively, as these can provide food sources for fungi. Instead, consider using dry wood chips as a mulch alternative. Keep your grass cut short and trim trees and bushes to increase surface temperatures and UV exposure, creating an environment that is less favourable for mushroom growth.
If you choose to remove existing mushrooms, it is important to do so before they release their spores. You can pull them out by hand, cut them with gardening shears, or mow over them. Ensure that you dispose of the mushrooms securely in a plastic bag to prevent spores from spreading.
By following these steps, you can effectively prevent and manage lawn mushrooms, creating an unfavourable environment for their growth and maintaining a healthy, mushroom-free lawn.

Remove food sources like leaves, twigs, and animal waste
Mushrooms thrive in environments with high moisture and low light. They spread spores into the air and then disappear when the soil dries out or they eat their way through the organic matter they feed on. Mushrooms are considered unsightly and may be dangerous if you have young children or pets playing on your lawn.
To prevent mushrooms from growing, you should remove their food sources, such as fallen leaves, twigs, grass cuttings, and any other waste materials. Rake up leaves, pick up twigs, and remove any animal waste as quickly as possible. If your garden has a thick layer of thatch, you should also consider de-thatching, as this can contribute to mushroom growth.
If the mushrooms are pervasive, it is recommended to remove them by hand, with a spade, or by mowing over the entire area. Put the mushrooms in a plastic bag to prevent spores from spreading.
You can also dig out the soil beyond the affected area to remove any dead tree roots, old mulch, or wood that could be food sources for mushrooms. If you have an area where a tree used to stand, keep it well-raked and aerated to improve drainage, as mushrooms thrive in wet conditions.

Frequently asked questions
Mushrooms thrive in damp, shady, and organic-rich environments. To prevent mushrooms from growing, you should:
- Avoid overwatering your lawn.
- Water early in the day so that the lawn does not remain damp overnight.
- Aerate your lawn to improve drainage.
- Reduce shade by trimming back bushes and tree limbs.
- Rake up leaves, twigs, grass cuttings, and any other organic waste materials.
- Remove any large sources of organic matter, such as fallen tree trunks or roots, and add fresh soil.
Mushrooms spread through spores, so it is important to remove them carefully. To remove mushrooms from your lawn, you can:
- Pull them out by hand, wearing gloves, and place them in a plastic bag.
- Cut them with a knife or spade, ensuring you remove as much of the root as possible.
- Mow over the mushrooms with a lawnmower.
Mushrooms themselves are not harmful to your lawn. In fact, they are a sign of healthy soil as they indicate the presence of organic matter. However, some mushrooms are toxic and can be dangerous if ingested by children or pets. Therefore, it is best to remove mushrooms from your lawn, especially if you have children or pets who may be tempted to put them in their mouths.
