Pull out the mushrooms and apply a mixture of vinegar and water to the affected areas
While mushrooms can be beneficial to lawns, helping to break down dead material and returning nutrients to the soil, they can also be a nuisance, especially if you have children or pets and the mushrooms are toxic. If you want to get rid of mushrooms, it's important to act quickly once you see the caps appear, as they will release spores if left too long, leading to more mushrooms.
One effective method for killing mushrooms is to pull them out of the ground and apply a mixture of vinegar and water to the affected areas. Here's a step-by-step guide:
- As soon as you see mushroom caps appearing, pull them out of the ground. Be careful when removing them, as mushroom spores spread easily. Simply plucking the mushrooms may not kill them, as they often have a larger structure beneath the surface of the soil.
- To kill the mushrooms and prevent them from growing back, create a mixture of vinegar and water. For this mixture, use horticultural vinegar, which is stronger than the vinegar typically found in kitchen cabinets. Mix one part vinegar with four parts water in a spray bottle.
- Mist the soil where the base of each mushroom was with the vinegar and water mixture. Do this daily for five days to ensure that the mushrooms don't grow back.
- Alternatively, you can apply a nitrogen fertilizer to the affected areas. The fertilizer will quicken the decomposition of organic matter, leaving the mushrooms with nothing to feed off of. For every 1,000 square feet of lawn, use 1 pound (453.59 grams) of nitrogen. You can also add some phosphorous and potassium to the fertilizer.
- In addition to the vinegar and water mixture, you can mix dish soap and water to help kill off the mushrooms. Combine 2 to 3 tablespoons (29.6 to 44.4 ml) of dish soap with 2 gallons (7.57 liters) of water. Poke holes into the soil around the mushrooms and pour the soapy water mixture into these holes.
- To further deter mushroom growth, maintain a clean yard. Mushrooms thrive in areas with decomposing leaves, grass clippings, and other organic matter, so regular yard clean-up can help prevent their growth.
By following these steps, you can effectively kill orange mushrooms and prevent them from returning. Just be cautious when handling mushrooms, especially if you're unsure about their toxicity, and always prioritize safety when working with vinegar, wearing long pants, sleeves, and eye protection.

Mix baking soda with water and spray it on the mushrooms and the surrounding soil
If you have orange mushrooms in your yard, it could be a species of stinkhorn mushrooms, which are known to emit an odour resembling decaying flesh. These mushrooms, along with other types, can be harmful to both humans and animals, so it's important to address the issue.
One effective method to kill mushrooms is to mix baking soda with water and spray it on the mushrooms and the surrounding soil. Baking soda is a natural fungicide that helps raise the pH level of the soil, creating an unfavourable environment for mushrooms. Here are some detailed steps to follow:
- Prepare the baking soda solution: Mix equal parts baking soda and water in a spray bottle. Ensure the baking soda is fully dissolved in the water by shaking the bottle gently. Label the bottle clearly to avoid any confusion.
- Protect yourself: While baking soda is generally safe, it's a good idea to wear gloves, long pants, and sleeves, especially if you have sensitive skin. Eye protection is also recommended to prevent any accidental spray from getting into your eyes.
- Remove mushroom caps: Before spraying, it's important to remove any visible mushroom caps by pulling them out of the ground. Be careful not to mow or rake the area, as this can spread the spores. Place the removed caps in a plastic bag and discard them properly to prevent further spore dispersal.
- Spray the affected area: Thoroughly spray the baking soda solution on the mushrooms and the surrounding soil. Ensure that you cover the entire area, including the base of the mushrooms. Pay extra attention to any shaded, damp areas, as mushrooms thrive in such conditions.
- Repeat the process: For best results, you may need to treat the area with baking soda multiple times. Mushrooms can be persistent, and it may take a few applications to effectively kill them. Allow some time between each treatment and observe the area for any new mushroom growth.
- Clean up and maintenance: Regular yard clean-up is essential to prevent mushroom spores from spreading. Remove damp leaves, debris, and any organic matter that mushrooms can feed on. Improving drainage in the area can also help reduce the moisture that mushrooms need to grow.
While this method is effective, keep in mind that baking soda can harm grass and other plants in the area. Always test the solution on a small area first and monitor the grass's reaction. Additionally, combining this approach with other natural methods, such as using vinegar or neem oil, can create a more comprehensive defence against mushroom growth.

Use dish soap by agitating 1-2 tablespoons into 3 gallons of water and pour it over the mushrooms
To kill orange mushrooms using dish soap, start by mixing 1-2 tablespoons of dish soap with 3 gallons of water. It's important to note that while dish soap counteracts the hyphae (elongated filamentous branches found in fungi), using high soap concentrations can affect the soil's pH balance and impact grass growth. Therefore, it is recommended to test the pH of your soil before applying the soap mixture.
Once you have prepared the mixture, aerate the soil around the mushrooms to ensure proper drainage. Then, pour the soapy solution over and around the mushrooms. Within 24 hours, the dish soap mixture will start working to kill off the unwanted fungi. For larger colonies of mushrooms, you may need to repeat this process.
Alternatively, you can poke holes into the soil around the mushrooms using a shovel, trowel, or screwdriver, and fill these holes with the soapy water mixture. This method ensures that the soap reaches the roots of the mushrooms.
In addition to using dish soap, there are other methods to kill mushrooms. Natural fungicides like baking soda, vinegar, and neem oil are environmentally friendly options. Applying a nitrogen fertilizer can also deter mushroom growth by quickening the decomposition of organic matter, leaving the mushrooms with nothing to feed off of.

Mow over the mushrooms, but be aware that this will increase the chances of spores spreading
Mushrooms are a common occurrence in lawns and gardens, and while some may find them harmless, others may want to get rid of them, especially if they are toxic or harmful to children and pets. Mushrooms are the above-ground symptoms of existing beneficial fungal growth, and they can break down organic material, return nutrients to the soil, and help soil retain water. However, if you want to get rid of them, one option is to mow over the mushrooms.
Mowing over the mushrooms is a quick and easy way to remove them from your lawn or garden. However, it is important to note that this method can increase the chances of spores spreading across your lawn. Mushrooms spread through spores, and when you mow over them, the force of the mower can cause these spores to be released and dispersed across your lawn. These spores can then find a new place to grow and establish themselves, leading to more mushrooms. Therefore, if you choose to mow over the mushrooms, it is essential to take precautions to minimize spore spread.
To reduce the chances of spore spread, it is recommended to mow over the mushrooms as soon as they appear, before they have had a chance to release their spores. Additionally, you should avoid mowing when the grass is wet, as moisture can contribute to spore spread. Make sure to set your mower to the highest setting to minimize direct contact with the mushrooms. After mowing, properly dispose of the mushroom remnants by collecting them in a plastic bag and discarding them in the trash.
While mowing can be effective in removing the visible mushrooms, it is important to note that it does not address the underlying fungal growth. To completely eradicate mushrooms, you must target the fungus beneath the soil. This can be done by reducing the food source for the fungi, such as removing decomposing organic matter like grass clippings, leaves, and branches. Additionally, improving drainage and aerating your lawn can help deter fungal growth. In some cases, you may need to dig out the affected soil to remove the fungal mat below the surface.
In summary, mowing over the mushrooms can be a quick solution, but it may not be the most effective long-term strategy. It is important to combine mowing with other methods, such as proper yard maintenance and targeting the underlying fungal growth, to successfully kill the mushrooms and prevent their recurrence.
