What You'll Learn
Horticultural vinegar is the most effective type of vinegar for killing mushrooms
Although mushrooms can be beneficial to the health of your lawn, you may want to get rid of them for various reasons. One way to do this is by using vinegar. Vinegar contains acetic acid, which is effective in killing mushrooms and preventing them from returning. However, not all types of vinegar are suitable for this purpose.
The most effective type of vinegar for killing mushrooms is horticultural vinegar, also known as industrial vinegar. This type of vinegar has a higher concentration of acetic acid and higher pH levels, making it more effective in killing mushrooms and preventing their regrowth. It is important to note that horticultural vinegar is more potent than the typical vinegar used in cooking or salads, and it should be handled with care as it can cause skin irritation and eye damage. When using horticultural vinegar, be sure to wear protective gloves and eye protection.
To use horticultural vinegar for killing mushrooms, it is recommended to dilute it with water before applying it to the affected areas. The suggested ratio is one part vinegar to four parts water. Mix this solution in a spray bottle and apply it directly to the mushrooms, being careful not to spray it on desired plants or grass as it can be harmful to them.
By following these steps and using horticultural vinegar, you can effectively kill mushrooms in your lawn or garden while also preventing their return. It is a natural and effective alternative to chemical fungicides.

How to make an anti-fungal spray with vinegar
Vinegar is an effective ingredient to use when making an anti-fungal spray. It is a natural fungicide and herbicide due to the acetic acid it contains, which kills mushrooms and prevents them from returning.
The most effective type of vinegar to use when making an anti-fungal spray is horticultural vinegar, also known as industrial vinegar. This is because it has higher pH levels and is not heavily diluted. However, it is important to note that vinegar concentrate can cause severe burns to the skin and eyes, so it is recommended that you wear safety gloves and eye protection when handling it.
To make the anti-fungal spray, follow these steps:
- Dilute the vinegar concentrate with water. The ratio should be about 1 part vinegar to 4 parts water.
- Transfer the vinegar solution into a spray bottle. You can use a funnel to make this step easier.
- Stand about 4 to 6 inches away from the affected area and spray a healthy amount of the solution onto it.
- Monitor the areas you have sprayed to see how it has affected the mushrooms and the surrounding area. If there is minimal to no damage to the surrounding plants and grass, continue spraying the remaining mushrooms.
If you are using the anti-fungal spray on your skin, you can follow a similar recipe by combining apple cider vinegar, aloe vera gel, and witch hazel into a glass spray bottle. This spray can be applied to the affected area and allowed to air dry. It can be used 2-3 times daily until symptoms disappear.
It is important to note that vinegar is not always effective against all types of fungi, and it can also kill plants and grass. Therefore, it is recommended to test the spray on a small area before applying it more broadly.

Other household items that can kill mushrooms
While vinegar is a great natural fungicide and herbicide for killing mushrooms, there are other household items that can be used to kill them too.
One such item is baking soda. Mix 2 tablespoons of baking soda with 1 gallon of water and either pour the mixture onto the mushrooms from a bucket or transfer it into a spray bottle.
Another option is dish soap. Combine 2 tablespoons of dish soap with 3 gallons of water and spray the solution directly onto the mushrooms. Alternatively, you can mix 3 tablespoons of dish soap with 2 gallons of water and pour the mixture into the soil to keep the mushrooms away.
Fertilizers are another way to combat mushroom growth. While they don't kill mushrooms, they can help prevent an outbreak by promoting plant growth and increasing the time it takes to decompose organic matter, thereby decaying the mushrooms' food source. Nitrogen-based fertilizers are particularly effective in this regard.
Finally, simply digging up and removing the mushrooms is an effective way to get rid of them. Put on some gloves and use a shovel or spade to dig out the cluster of mushrooms, going at least 12 inches down to remove as much of the fungus as possible. Place the mushrooms in a sealed plastic bag and throw them away in the bin, not with your lawn waste, to prevent further fungal growth.

How to prevent mushrooms from growing in mulch
Mushrooms thrive in mulch because it is rich in decaying matter, creating an acidic substrate that fungi love. While some mushrooms can benefit your lawn's health, they can also be toxic and unsightly. Therefore, it is important to know how to prevent mushrooms from growing in mulch. Here are some methods to stop mushrooms from taking over your mulch:
Use Vinegar
A common household item, vinegar is an effective way to kill mushrooms due to its acetic acid content. To make a simple anti-fungal spray, mix one part vinegar with four parts water and apply it directly to the mushroom-infested mulch. However, be cautious as vinegar can also kill plants and grass. It is recommended to use an industrial type of vinegar called horticultural vinegar, which has higher pH levels.
Improve Air Circulation and Drainage
Mushrooms thrive in damp and dark environments, so ensure your mulch has good air circulation and drainage. Use shredded bark or cedar chips, which generally provide better air circulation and drainage than other types of mulch. Regularly rake your mulch to aerate it, making it less welcoming to mushrooms.
Remove Food Sources
Mushrooms feed on decaying matter, so removing their food sources can help prevent their growth. Keep your lawn and garden free of fallen leaves, grass clippings, compost, and other organic debris. Additionally, avoid over-watering your plants as mushrooms can be a sign of excessive moisture.
Use Fertilizers
Nitrogen-rich fertilizers can help combat mushroom growth in two ways. Firstly, they promote plant growth, reducing the amount of decomposing organic matter available for mushrooms. Secondly, some fertilizers contain properties that prevent fungal growth. However, avoid slow-release fertilizers as they won't have the same effect.
Apply Baking Soda or Lime
Baking soda can be used to raise the alkalinity of the soil, making it less conducive for mushroom growth. Mix one tablespoon of baking soda with one gallon of water and spray it on the affected areas. Lime can also be used, as it changes the pH of the soil, but it may not be as effective as expected and can be harmful to plants. Always consult a gardening expert before using lime.
Use Fungicides
Commercial fungicides can be effective in preventing mushroom growth in mulch. However, they may not be successful in eradicating mushrooms once they have taken root. Always follow the product label instructions and take the necessary safety precautions when using any chemical treatments.
