Mushrooms in your yard are a sign of healthy soil, but they can be unsightly and some may be poisonous. Mushrooms are part of the fungus family, and they thrive in damp, dark environments with organic matter. To get rid of mushrooms, you can try improving drainage and sunlight, removing decaying organic matter, using natural fungicides like vinegar or baking soda, mowing over them, or picking them by hand (while wearing gloves). While it may be difficult to completely eliminate mushrooms, these methods can help control their growth and prevent them from becoming a nuisance in your yard.

Using natural fungicides like vinegar
Mushrooms in your yard are a sign of healthy soil. They break down decaying leaves and other organic matter, depositing nutrients in the soil. However, they can be harmful to pets and children, so it is important to get rid of them.
One way to kill mushrooms in your yard is to use natural fungicides like vinegar. The acetic acid in vinegar will kill the mushrooms. Here's how you can do it:
First, put on a pair of gloves. You should always wear gloves when handling mushrooms as some of them can be poisonous. Then, mix a solution of vinegar and water. The solution should be mixed in a ratio of 1:4, i.e., one part vinegar and four parts water. It is important to ensure that the vinegar is diluted sufficiently, as undiluted vinegar can be harmful to your grass.
Next, pour the solution into a spray bottle and spray it directly onto the mushrooms. Be careful where and when you spray, as vinegar will kill anything else it comes into contact with. Alternatively, you can pour the solution directly onto the mushrooms and let it drain into the soil. This method will help ensure that the vinegar reaches the roots of the mushrooms, effectively killing them.
You can also use baking soda as a natural fungicide. Baking soda raises the pH of the soil, creating an environment that is inhospitable to mushrooms. Dissolve two tablespoons of baking soda in a gallon of water and pour it over and around the mushrooms. Make sure to aerate the soil before applying the solution to ensure that the water drains freely into the soil.
It is important to note that using natural fungicides may require multiple applications before you see results. Additionally, these methods will only remove the visible part of the mushroom and will not kill the fungi in the soil. To effectively remove the fungi, you may need to dig up the affected area and remove the fungi manually.

Baking soda to adjust soil pH
Mushrooms in your yard are a sign of healthy soil. While not all mushrooms are poisonous, some are, and they can be harmful to pets and children. Mushrooms thrive in damp, dark environments, and they can be removed by mowing the lawn and raking them away. However, this only removes the 'fruit' part and does not kill the fungi in the soil.
Baking soda is a safe and natural way to kill mushrooms in your yard. It is also known as sodium bicarbonate, a compound that is basic on the pH scale. By dissolving 1-2 tablespoons of baking soda in a gallon of water and pouring it around and over the mushrooms, you can raise the pH of the soil, making it less acidic and creating an unfavourable growing environment for the mushrooms. This method may need to be repeated several times to see results.
While baking soda is effective in killing mushrooms, it is important to use it sparingly as it can cause salt buildup in the soil. This salt buildup can damage foliage and make the soil uninhabitable for plants until it washes away. Baking soda is best used as a spot treatment rather than a long-term solution for adjusting soil pH.
In addition to using baking soda, you can also improve your yard's drainage and airflow by aerating the lawn and removing decaying leaves, wood, and other organic matter that mushrooms feed on. By reducing the moisture and organic matter in your yard, you can make it less inviting for mushrooms to grow.

Removing decaying organic matter
Mushrooms thrive in damp, dark environments, breaking down organic matter in your lawn and yard. They are often found in dead patches of lawn that are thick with thatch and covered in leaves, or areas under trees with lots of soggy leaf mould, decaying tree stumps and branches.
To remove decaying organic matter, you can:
- Remove dead tree roots, old mulch, decaying leaves, wood, and pet waste.
- Rake up grass clippings and dethatch your yard.
- Mow over the mushrooms and pick up the pieces, then throw them away in a sealed bag.
- Dig out the mushrooms with a shovel or spade, removing as much of the fungus as possible.
- Decrease shady spots by trimming trees and bushes and mowing more often to let additional sunlight through.
- Improve drainage by aerating the lawn.
- Water your lawn in the early morning so it has time to dry before dark, and add no more than 1 inch of water per week.
To prevent mushrooms from returning, you can apply a natural fungicide such as vinegar (diluted with 4 parts water to 1 part vinegar) or baking soda (dissolved with 2 tablespoons of baking soda per gallon of water). However, keep in mind that these treatments will also kill other plant life that they come into contact with.

Improving drainage and sunlight
Mushrooms thrive in damp, shaded spots with decaying organic matter to feed off. Therefore, improving drainage and increasing sunlight in your yard can help prevent mushroom growth.
Improving drainage
- Aerate your lawn: Create proper drainage by aerating your lawn, which will allow water to drain and prevent it from sitting on top of your grass and encouraging mushroom growth.
- Fix clogged gutters: Gutters that are not functioning properly can cause flooding in your yard, leading to moist soil that mushrooms thrive in.
- Remove decaying organic matter: Mushrooms feed off decaying organic matter such as dead tree roots, old mulch, decaying leaves, grass clippings, and wood. By removing these, you reduce the food source for mushrooms.
Increasing sunlight
- Prune large trees and bushes: Mushrooms thrive in dark places, so trim your trees and bushes to let more sunlight into your yard.
- Mow more often: Mowing your lawn more frequently will also help to increase sunlight penetration and reduce shady spots where mushrooms can grow.
It is important to note that improving drainage and increasing sunlight alone may not be enough to completely eradicate mushroom growth. For more effective methods, consider using natural fungicides such as vinegar or baking soda, or commercially available fungicides.

Picking and disposing of mushrooms
Mushrooms are a sign of a healthy yard and healthy soil. However, they can be unsightly and may be harmful to pets and children.
Picking Mushrooms
- Wear gloves when picking mushrooms as some may be poisonous.
- Pick mushrooms as soon as you see them.
- You can pull mushrooms up individually by hand, cut them with a knife, or mow over them with a lawnmower.
- If you mow over them, be sure to pick up the pieces and throw them away in a plastic bag.
- Mushrooms thrive in damp, dark environments, so keep your grass cut low, and remove debris such as dead tree roots, old mulch, decaying leaves, wood, and pet waste.
- Rake your lawn to dry it out, and cut tree branches to allow more sunlight in.
- Mushrooms can also be a sign of excess water, so improve drainage and avoid over-watering your lawn.
- Mushrooms are more likely to grow in dead patches of lawn that are thick with thatch and covered in leaves, so remove thatch and leaves.
Disposing of Mushrooms
- Do not dispose of mushrooms in your compost bin, as they will release spores and grow new mushrooms.
- Throw mushrooms into a plastic bag, tie it tightly, and throw it in the trash.
- If you want to kill the mushrooms before disposing of them, spray them with a mixture of vinegar and water. Be aware that vinegar will kill anything it comes into contact with, so spray carefully.
- Another option is to use baking soda, which raises the pH of the soil. Dissolve 2 tablespoons of baking soda in a gallon of water, aerate the soil around the mushrooms, and pour the mixture over them.

Frequently asked questions
Mushrooms thrive in damp, dark places, so it's important to ensure your yard is well-lit and free of standing water. You can do this by improving drainage and avoiding overwatering your garden.
You can use natural fungicides such as vinegar (diluted with water) or baking soda (dissolved in water). Be careful when using vinegar, as it will kill anything it comes into contact with.
Yes, commercial fungicides are available, but they only kill the "fruiting bodies" of the mushrooms. Therefore, prevention and maintaining a healthy lawn are better strategies.
You can mow over the mushrooms, then pick up and dispose of the pieces. You can also dig up the mushrooms and the surrounding soil to remove as much of the fungus as possible.
