Mushrooms in your lawn can be unsightly, and some varieties are toxic, which can be dangerous for pets and children. While mushrooms are a sign of healthy soil, they can be an eyesore and a cause for concern. There are several methods to kill mushrooms, but it's important to note that most of these methods will only remove the 'fruit' part and not the fungi in the soil. One popular method is to use a natural fungicide, such as vinegar, diluted with water and sprayed directly onto the mushrooms. However, this will also kill anything else it comes into contact with. Another approach is to use baking soda or dish soap, which changes the pH level of the soil, making it inhospitable for mushrooms. Applying a high-nitrogen fertiliser can also help strengthen grass and ward off mushrooms. While some people recommend simply picking the mushrooms by hand, this can spread spores, so it's important to wear gloves and be cautious.

What You'll Learn
Pick mushrooms by hand to avoid spores spreading
Mushrooms are the fruits of the fungus world. They are spore-holders for reproduction and spread spores to new areas by wind, animals, and water. Simply plucking mushrooms is not enough to kill them, as they are often much larger beneath the surface of the soil. However, picking mushrooms by hand is an effective way to avoid spores from spreading.
When picking mushrooms, it is important to wear gardening gloves and remove the entire mushroom by the root. You can twist and pull the mushroom from the mycelium, or use scissors or a knife to cut the stem at its base, as close to the gills as possible. It is also important to carry the mushrooms with the gills facing down to prevent spores from spreading. Collecting mushrooms in a basket or porous cloth bag allows spores to disperse as you move.
To prevent mushrooms from growing back, you can apply a nitrogen fertilizer to deter mushrooms from growing in organic matter. Another option is to mix four parts water with one part horticultural vinegar in a spray bottle and mist the soil where the base of each mushroom was. Alternatively, you can create your own fungicide by combining vinegar and water and spraying it directly on the mushrooms.
It is important to note that most mushrooms are harmless and can even be beneficial to your lawn's health. However, some mushrooms can be toxic, especially if you have children or pets who may nibble on them. Therefore, it is crucial to properly identify the mushrooms before picking them and dispose of them in a plastic bag to prevent spores from spreading.
By following these steps, you can effectively pick mushrooms by hand and avoid the spread of spores.

Use dish soap and water to change the pH level in the soil
Mushrooms are a sign of rich and good-quality soil. However, they can be an eyesore and may be harmful. They thrive in damp, dark environments, breaking down organic matter in your lawn. To prevent mushrooms, keep your soil dry by mowing regularly and removing organic debris like grass clippings and fallen leaves.
If you want to kill mushrooms, you can use dish soap and water to change the pH level in the soil. Here's how:
First, locate the mushrooms you want to get rid of. Mix 1-2 tablespoons of dish soap with 3 gallons of water. Poke holes in the soil around the mushrooms with a screwdriver. Pour the soapy water over the mushrooms and into the holes to disrupt the fungi's life cycle below the soil surface. Make sure to aerate the area around the mushrooms first so that the water drains well. This process changes the pH level in the soil, creating an inhospitable environment for the mushrooms.
Repeat this process several times a day for a week for the best results. While this method is effective, it may not address the underlying causes of mushroom growth. It is also important to note that high soap concentrations can affect the soil's pH balance and impact grass growth, so it is recommended to test the mixture on a small area first.
Additionally, combining vinegar with water and spraying it on the mushrooms is another way to change the pH of the environment, killing spores. Baking soda can also be used to raise the soil's pH, but it may need to be repeated regularly to see results.

Apply a high-nitrogen fertiliser to strengthen grass and prevent mushrooms
Mushrooms are a common occurrence in lawns, especially after rainy seasons. They can be a nuisance, especially if you have children or pets, but they are usually harmless and can even be beneficial to your lawn's health.
If you want to get rid of mushrooms, one effective method is to apply a high-nitrogen fertiliser to your lawn. Mushrooms feed on organic matter, and high-nitrogen fertiliser speeds up the decomposition of this matter, leaving the mushrooms with nothing to eat. Nitrogen also boosts grass growth, which can crowd out mushroom colonies.
To effectively use a high-nitrogen fertiliser to prevent mushrooms, follow these steps:
- Choose the right type of fertiliser: Select a nitrogen-rich, slow-release fertiliser. Avoid using a water-soluble nitrogen fertiliser as it can be less effective in deterring mushrooms. You can find fertilisers specifically designed for grass that have a high nitrogen content.
- Determine the amount of fertiliser: The amount of nitrogen fertiliser you need depends on the size of your lawn. A general guideline is to use 1 pound (453.59 grams) of nitrogen for every 1,000 square feet of lawn.
- Prepare the lawn: Before applying the fertiliser, aerate your lawn by making small holes in the grass using an aerator or a gardening tool. This step helps the fertiliser and water reach the roots of the grass more easily.
- Apply the fertiliser: Spread the high-nitrogen fertiliser evenly across your lawn, following the instructions on the packaging for the appropriate application rate. It is best to apply fertiliser just before a day of light, steady rain so that the grass can absorb the nutrients effectively.
- Maintain lawn care: In addition to applying fertiliser, proper lawn care practices can help prevent mushrooms. This includes mowing your grass at the recommended height, adjusting your watering practices, and clearing your lawn of organic matter that can serve as food for mushrooms.
By following these steps and applying a high-nitrogen fertiliser correctly, you can strengthen your grass and create an environment that is less conducive to mushroom growth.

Rake mushrooms away after mowing the lawn
Mushrooms are a common occurrence in lawns, particularly in locations with high moisture and low light. They are usually harmless and can even be beneficial, as they break down organic material, deposit nutrients into the soil, and help soil retain water. However, they may be problematic if you have children or pets who might eat them, as it can be difficult to distinguish the non-toxic from the poisonous types.
If you want to get rid of mushrooms in your lawn, one option is to mow over them and then rake them away. Mowing over mushrooms quickly removes any visible fruiting bodies, improving the appearance of your yard. However, if the mushroom pieces are left on the lawn, they can spread spores, leading to more mushrooms. Therefore, it is important to rake and bag the clippings immediately after mowing and dispose of them in the trash. Additionally, be sure to clean your mower deck to avoid reintroducing the fungus.
To further prevent mushroom growth, you can improve drainage by aerating your lawn. This will help break up soil compaction, allowing water to percolate into the soil instead of sitting on top and creating a waterlogged environment conducive to fungal growth. You can also reduce shady spots on the lawn by trimming back bushes and tree limbs, as most fungi thrive in dark environments.
If you want to get rid of mushrooms without mowing, you can also try hand-picking them, ensuring you remove the entire mushroom by the root and wearing gardening gloves. You can then put the mushroom caps in a plastic bag and discard them to prevent the spread of spores.

Use baking soda dissolved in water to raise the pH of the soil
Baking soda, or sodium bicarbonate, is an effective agent for killing mushrooms. It is a popular method among homeowners as it is non-toxic, inexpensive, and readily available in most kitchens. Baking soda helps raise the pH level of the soil, making it more alkaline and creating an unfavourable environment for mushrooms, thus impeding their growth.
To use baking soda to kill mushrooms, start by mixing two tablespoons of baking soda with one gallon (approximately three litres) of water. Stir the solution until the baking soda is completely dissolved. You can then use a sprayer to apply the solution directly to the mushrooms and the surrounding soil. Alternatively, you can pour the solution over the mushrooms and the aerated soil, allowing it to drain freely.
When using this method, it is important to note that while baking soda is effective in disrupting mushroom growth, it may not be a permanent solution. Fungi will stop growing in alkaline conditions, but they could return once the soil conditions improve. Additionally, significant changes to the soil's pH level may inhibit the growth of other plants in the immediate area. Therefore, it is recommended to exercise caution and test the solution on a small area before applying it more extensively.
Combining baking soda with other methods can enhance its effectiveness in killing mushrooms. For example, alternating between using baking soda sprays and vinegar sprays can help keep the pH of the soil neutral. However, it is important to be cautious when using vinegar as it could increase the acidity of the yard, potentially harming the grass. Additionally, while commercial fungicides can be effective in killing mushrooms, they may introduce new poisons into the yard, posing risks to pets and children. Therefore, natural alternatives like baking soda are often preferred.
