Mushrooms are the visible manifestation of a long-running underground process. They thrive in humid, dark, and nutrient-rich places and can be poisonous. If you want to get rid of mushrooms, baking soda (sodium bicarbonate) is a simple, easy, and effective way to kill them and their spores. It works by elevating the soil's pH level, turning it alkaline, and making it an undesirable place for mushrooms to live. To create a balanced mix, combine two teaspoons of baking soda with a gallon of water and spray it over the affected area. This process can take up to three days or longer, but it's a safe and natural alternative to chemical fungicides.

Baking soda and water solution
Mushrooms are the visible manifestation of a long-running underground process. They thrive in humid, dark, and nutrient-rich places and spring up when three elements come together: moisture, the right amount of light, and the right temperature.
Baking soda (sodium bicarbonate) is a simple and effective compound that can be used to kill mushrooms. It works by elevating the soil's pH level, turning it alkaline, and making it an undesirable place for mushrooms to live.
To make a baking soda and water solution, combine one gallon of water with one or two tablespoons of baking soda in a bucket and mix until the baking soda is completely dissolved. Fill a garden sprayer with the solution and apply it to the mushrooms and surrounding soil. This process may need to be repeated as the effect is not permanent, and mushrooms may return once soil conditions improve.
While baking soda is a safe and natural treatment, it is important to note that it may take up to three days to see results. Additionally, it is crucial to get the right concentration to avoid burning your lawn by killing all fungi at once. To prevent mushrooms from returning, ensure your lawn drains well and doesn't stay wet for too long, as water encourages the growth of fungi spores.

How to apply the solution
Killing mushrooms with baking soda is an effective and safe method, as baking soda does not harm your skin. It is also a cost-effective alternative to chemical fungicides. Here is a step-by-step guide on how to apply the baking soda solution to eliminate unwanted mushrooms:
Prepare the Baking Soda Solution:
Mix one tablespoon or two teaspoons of baking soda with one gallon of water in a bucket or large container. Stir the mixture until the baking soda is completely dissolved and you have a uniform solution. The concentration of baking soda is important—too much can burn your lawn by killing off all fungi at once.
Apply the Solution:
Use a garden pump sprayer or a spray bottle to apply the baking soda solution directly to the mushrooms you want to eliminate. Spray the stems and caps of the mushrooms, ensuring complete coverage. You can also spritz the surrounding soil to make the area less desirable for future mushroom growth.
Alternatively, you can use a spoon or cup to sprinkle baking soda around the affected area. This method may be more suitable if you have a large number of mushrooms or want to cover a wider area. After sprinkling, water the area lightly to help dissolve the baking soda into the soil.
Post-Treatment Care:
It typically takes up to one day for the baking soda solution to kill mushrooms, but in some cases, it can take up to three days or longer. Be patient and monitor the treated area during this period. If you still notice mushroom growth after two days, reapply the baking soda solution.
To prevent future mushroom growth, improve the drainage in your lawn to avoid waterlogged conditions that favour mushrooms. You can also reduce watering to keep your lawn drier, as mushrooms thrive in humid environments.
Additionally, consider creating a barrier between your lawn and the grass outside to prevent the ingress of fungal spores. Remember that baking soda's effect on soil pH is temporary, so mushrooms may return once soil conditions become favourable again.
Always wear gloves when handling and disposing of treated mushrooms to ensure you do not inadvertently spread their spores to other areas.

Why baking soda works
Baking soda, or sodium bicarbonate, is an effective way to kill mushrooms and prevent their growth. Mushrooms are a fleshy, spore-bearing fruiting body of a fungus that grows above ground, on soil, or on its food source. They thrive in humid, dark, and nutrient-rich environments and require moisture to avoid drying out.
Baking soda works by elevating the soil's pH level, turning it alkaline, and thus altering the soil's pH. This makes the soil an undesirable place for mushrooms to live. To create a balanced mix, you can combine one tablespoon or two teaspoons of baking soda with one gallon of water. This solution can then be sprayed over the affected areas, including the mushroom caps and stems, or sprinkled directly over the soil and watered.
Baking soda is a safe and effective alternative to chemical fungicides, as it does not harm your skin upon direct contact. It is a simple and inexpensive way to inhibit mushroom growth and prevent the need for chemical solutions. However, it's important to get the right concentration to avoid burning your lawn by killing all fungi at once.
In addition to baking soda, other natural treatments for mushrooms include dish soap and water, vinegar, and commercial fungicides. Preventative measures, such as proper lawn drainage and creating a barrier between your lawn and outside grass, can also help discourage mushroom growth by depriving them of moisture and preventing spore colonization.

Natural alternatives to baking soda
While baking soda is a natural and effective fungicide for killing mushrooms, it may not be a long-lasting solution. Mushrooms thrive in acidic environments, and baking soda raises the pH of the soil, making it more alkaline. However, once the baking soda is washed away, the soil will return to its normal pH, and mushrooms could return. Here are some natural alternatives to using baking soda to kill mushrooms:
Vinegar
Like baking soda, vinegar is a natural fungicide that kills mushrooms without damaging your lawn. It contains acetic acid, which prevents mushrooms from returning. It is important to note that most household vinegar has a lower pH than is required to effectively kill mushrooms, so it is recommended to use industrial-grade vinegar. Always wear safety gloves when mixing vinegar with water.
Dish Soap and Water
A dish soap-water mixture is a safe way to eliminate lawn mushrooms without killing the grass. However, it is important to use the proper concentration on the affected areas.
Nitrogen-Rich Fertilizers
Nitrogen-rich fertilizers can be used to hasten the decomposition of organic matter that mushrooms feed on. By breaking down this organic matter, you can deprive the mushrooms of their food source and inhibit their growth.
Lawn Maintenance
Proper lawn maintenance is key to preventing mushroom infestations. Ensure your lawn has well-drained soil and introduce proper drainage if necessary. Remove any decaying elements, provide good aeration, and trim the surrounding tree branches. These measures will make your lawn less favourable for mushroom growth.

Preventative measures
To prevent mushrooms from growing in your lawn, it is important to understand the conditions that facilitate their growth. Mushrooms are the visible manifestation of a long-running underground process. This fungus grows and feeds on decaying organic matter in the soil, aided by poor drainage, lack of sunlight, and moisture retention.
- Ensure your lawn drains well and doesn't stay wet for too long. Install a French drain if necessary to facilitate faster water runoff.
- Create a barrier between your lawn and the grass outside to prevent fungal spores from colonizing your soil.
- Keep your lawn dry by watering it less frequently and addressing any moss or green specks immediately.
- Remove mushrooms' favourite places to grow, such as rotted stumps, tree branches, and grass clippings, using a thatching rake.
- Maintain your lawn all year round to promote healthy grass and reduce the chances of mushroom growth.

Frequently asked questions
Yes, baking soda kills mushrooms. It contains sodium bicarbonate, a chemical compound that has been used to remove harmful fungi for several decades.
Baking soda works by killing off the fungus when they come into contact with it and absorb its nutrients through their cell membranes. It also elevates the soil's pH level, turning it alkaline, thus altering the soil's pH and making it an undesirable place for mushrooms to live.
Mix one tablespoon or two teaspoons of baking soda with one gallon of water. Put the mixture in a spray bottle and spray it over the mushrooms and the surrounding soil. You can also sprinkle baking soda directly over the soil and then water it.
It typically takes up to a day for the baking soda solution to kill mushrooms. However, in some cases, it can take up to three days or longer.
