Vinegar kills mushrooms but not grass/plants
Mushrooms in your lawn can be unsightly and even dangerous, especially if you have children or pets. While vinegar can effectively kill mushrooms, it's important to take precautions to avoid damaging your grass and plants. Here's how vinegar can be used to eliminate mushrooms without harming your greenery:
Vinegar Kills Mushrooms:
The active ingredient in vinegar, acetic acid, is effective at killing garden mushrooms. To make a homemade fungicide, mix one part vinegar with four parts water in a spray bottle. Spray this solution directly onto the mushrooms, ensuring that you saturate both the mushrooms and the surrounding soil. This mixture will desiccate the mushrooms, leading to their demise.
But Be Cautious to Protect Grass and Plants:
While vinegar is a powerful tool against mushrooms, it is crucial to remember that vinegar can also kill plants and grass. When applying the vinegar solution, be careful not to get it on your garden plants or grass. Vinegar is non-selective and will damage any plant material it touches. This means that while you're targeting the mushrooms, you could unintentionally harm your desired vegetation.
Additional Precautions:
To further protect your grass and plants, it is recommended to wear latex gloves when handling mushrooms to prevent the spread of spores. Additionally, properly dispose of the mushrooms by placing them in a plastic bag and discarding it in a trash can or incinerator, rather than tossing them into your compost pile.
Alternative Methods:
If you're concerned about using vinegar due to the risk of harming your grass or plants, there are alternative methods to consider. One option is to use baking soda, which raises the soil pH and halts mushroom growth. Dissolve two tablespoons of baking soda in a gallon of warm water and pour it over the mushrooms and surrounding soil. However, as with vinegar, be cautious not to get baking soda on your desired vegetation. Commercial fungicides are also an option, but be sure to follow the label instructions carefully to avoid overapplication.

How to mix vinegar with water
Mixing vinegar with water can be useful for cleaning and killing garden mushrooms. Here is a step-by-step guide on how to mix vinegar with water:
Firstly, it is important to note that vinegar is a strong acid and should be diluted with water for most applications. The dilution ratio will depend on the intended use. For example, for routine household cleaning, a 1:1 ratio of vinegar to water is often recommended, which can be adjusted based on the toughness of the job or the sensitivity of the surface. For cleaning painted walls and doors, a less concentrated solution of 2-3 tablespoons of vinegar in a gallon of water is suggested. On the other hand, for killing mushrooms, a stronger solution of 1 part vinegar to 4 parts water is recommended.
Next, the type of water used can vary. Distilled water is suggested for mixing with vinegar in a spray bottle, especially if the solution will be used over an extended period. Warm water can also be used, as it helps boost the effectiveness of the mixture and aids in dissolving grease and hard water spots.
Then, optional ingredients can be added to enhance the mixture. For cleaning solutions, essential oils can be added to improve the scent, as vinegar has a strong odour. Additionally, lemon peels or pine twigs can be soaked in the vinegar for a natural disinfectant and a festive fragrance. However, adding fresh ingredients may reduce the shelf life of the solution to only a day or two.
Finally, the mixture should be combined and applied appropriately. For cleaning solutions, the diluted vinegar can be applied with a washcloth, mop, or sprayed directly onto the surface and then wiped clean with a microfiber cloth or sponge. For killing mushrooms, the solution should be sprayed directly onto the fungi, taking care not to spray surrounding plants or grass, as vinegar can be harmful to them.

How to apply vinegar to mushrooms
Vinegar can be an effective way to kill mushrooms, but it is important to be cautious as vinegar can also damage or kill surrounding plants and grass.
First, put on some gloves to protect your hands from potentially poisonous mushroom spores. Then, pull each mushroom cap out of the ground by hand and place them in a plastic bag to prevent the spores from spreading. To kill the mushrooms, mix a solution of four parts water with one part vinegar in a spray bottle. Spray the mushrooms and the surrounding soil with the solution, being careful not to get it on any plants or grass you want to keep.
Alternatively, you can mix two tablespoons of baking soda with a gallon of warm water and pour this mixture over the mushrooms and the surrounding soil. Baking soda raises the soil pH and prevents mushroom growth. However, like vinegar, it can damage grass and plants if applied too heavily.
It is also important to note that simply removing or killing the mushrooms may not be a long-term solution, as they often indicate rich, high-quality soil that can continue to support their growth. To prevent mushrooms from returning, you may need to take additional steps such as aerating the soil, applying a nitrogen fertilizer, or treating the area with a commercial fungicide.

Other ways to kill mushrooms
While vinegar is a good option for killing mushrooms, it is not the only option. Here are some other ways to kill mushrooms:
Soap and Water
Mix 1-3 tablespoons of dish soap with 2-3 gallons of water. Poke holes in the soil around the mushrooms and fill them with the soapy water. This method changes the pH level in the soil, which can be harmful to grass if done too frequently or in too high a concentration.
Mowing or Raking
Mowing or raking over the mushrooms can help remove them, but it may also spread their spores across your lawn, leading to more mushrooms. If you choose this method, be sure to supervise young children and pets to ensure they do not ingest any mushrooms.
Nitrogen Fertilizer
Apply a nitrogen-rich fertilizer to the soil where the mushrooms were growing. This will kill the roots and prevent the mushrooms from returning.
Fungicide or Herbicide
Apply a small amount of fungicide or herbicide to the affected area. These can be found at most home improvement or gardening stores. Be sure to apply during dry weather, as rain can wash away the treatment and prevent it from settling in effectively.
Cornmeal
Some gardeners swear by cornmeal as a natural fungicide. Apply it to the affected area to discourage fungal growth.
It is important to note that mushrooms are a sign of healthy soil, and many of them are beneficial to lawns. However, they can also be a source of concern if you have children or pets, especially if the mushrooms are toxic. Always take precautions when handling mushrooms and supervise young children and pets to ensure they do not ingest them.

Why vinegar kills mushrooms
Mushrooms are a common eyesore in lawns and gardens. They grow from fungi in the soil, which thrive in damp, dark conditions. When the conditions are right, the fungi send up mushrooms to reproduce and spread their genetic material. While mushrooms can be beneficial to lawns as they break down dead material and return nutrients to the soil, they can also be a nuisance, especially if they are toxic.
Vinegar is an effective way to kill mushrooms. It contains acetic acid, which is harmful to mushrooms. To use vinegar to kill mushrooms, mix one part vinegar with four parts water in a spray bottle. Spray the mixture directly onto the mushrooms and the surrounding soil. This will desiccate the mushrooms, killing them. However, it is important to be careful when using vinegar as it can also kill plants and grass. Do not spray the vinegar solution on any garden plants or grass, as it will damage or potentially kill them.
It is also important to remove the mushrooms from the ground as soon as they appear. If left for too long, they will release spores, which will lead to more mushrooms. When removing mushrooms, wear gloves to protect your hands from potentially poisonous spores. Pull the mushrooms out of the ground and put them in a plastic bag. Seal the bag tightly and throw it away in a trash can or incinerator to prevent the mushrooms from spreading their spores.
In addition to vinegar, other methods to kill mushrooms include using baking soda, fungicides, or nitrogen fertilizer. Baking soda can be dissolved in warm water and poured over the mushrooms and surrounding soil. It raises the soil pH, making it unsuitable for mushroom growth. Commercial fungicides can also be effective, but it is important to follow the label instructions carefully to avoid overapplication. Applying a nitrogen fertilizer to the soil can deter mushrooms from growing in organic matter.
