What You'll Learn
Pick mushrooms by hand
Picking mushrooms by hand is an effective way to get rid of a small colony of mushrooms. It is also a natural alternative to using chemicals, which can be harmful to pets and people.
When picking mushrooms by hand, it is important to wear gloves to protect your hands from potentially poisonous spores. You should also try to remove as much of the cap and stalk as possible at the base of the mushroom. This is easiest to do when the mushrooms are still young and before the spores are released. If the mushrooms have roots that reach down into the soil, use a small spade or garden trowel to dig around the base and remove as much of the root structure as you can. Dispose of the mushrooms in a sealed plastic bag to prevent the spread of spores.
It is worth noting that simply plucking mushrooms does not kill them, as the mushroom is often much larger beneath the surface of the soil. Mushrooms will continue to produce more mushrooms for the duration of the fruiting season, even if you pick every single one by hand. Therefore, it is important to combine hand-picking with other methods, such as spraying the affected area with a mixture of vinegar and water or dish soap and water.

Use a commercial fungicide
If you're looking to kill mushrooms, you may want to consider using a commercial fungicide. While mushrooms can be a sign of rich, good-quality soil, they may also be harmful or simply an eyesore. Mushrooms are a fungus, and they thrive in damp, dark environments, breaking down organic matter in your lawn or yard.
Fungicides are an effective way to kill mushrooms as they target the fungus that started the mushroom growth. You can purchase a commercial fungicide to treat and kill the mushrooms in your lawn. It is important to note that fungicides will only kill the fruiting part of the fungi, so it is more effective to take preventative measures to stop mushrooms from growing in the first place. Maintain your lawn all year round to encourage healthy grass and reduce the chances of mushrooms taking hold.
When using a commercial fungicide, be sure to apply it when dry weather is predicted. Applying fungicide just before a rainstorm can prevent it from settling in effectively and may wash it off your lawn and into local ecosystems. You may need several applications, especially if you have a heavy infestation, as a large crop of mushrooms can leave many spores in the soil.
Some natural alternatives to commercial fungicides include compost teas obtained from different agronomical wastes and essential oils from aromatic plants. Compost teas take advantage of the intensive activity of the microbial community inhabiting these broths to control fungal diseases. Certain essential oils, such as oregano and geranium oil, have shown strong antifungal activity and are considered non-toxic and biodegradable. However, when using any substance to kill mushrooms, it is important to consider the potential impact on the surrounding ecosystem, especially if you have pets or children.

Reduce moisture and shade
Mushrooms thrive in moist, shady environments, so it is important to reduce moisture and increase sun exposure to prevent their growth. Here are some ways to do this:
Firstly, address any issues with drainage. You can do this by extending your home's downspout, drawing up a drainage plan, constructing a creek bed or French drainage system, or adding an underground drainage pipe. By improving drainage, you will reduce the moisture that mushrooms need to grow.
Next, trim any trees or bushes that are creating excessive shade. By trimming back these plants, you can increase sunlight and raise soil temperatures, making the environment less favourable for mushrooms.
Additionally, adjust your watering habits. Water your lawn in the mornings or keep a strict watering schedule to prevent overwatering. You can also aerate your lawn, which will help reduce moisture retention.
If you are dealing with indoor mushrooms, you can improve ventilation and sunlight exposure in the affected area. Also, ensure that any leaks or sources of moisture are eliminated.
Finally, removing visible mushrooms is crucial. You can do this by hand, with gardening shears, or by mowing the lawn. While this doesn't directly reduce moisture or shade, it helps prevent the spread of spores and can reduce the likelihood of future mushroom growth.

Baking soda to adjust soil pH
Mushrooms are a sign of rich and high-quality soil, but they can be unsightly and even dangerous. They thrive in damp, dark, and acidic environments, breaking down organic matter in the soil. While there are various methods to kill mushrooms, such as fungicides, vinegar, or picking them by hand, one popular method is to use baking soda to adjust the soil's pH level.
Baking soda, or sodium bicarbonate, is a common household item that can be used to effectively kill mushrooms. It is inexpensive, safe for children and pets, and non-toxic to the environment. By raising the pH level of the soil, baking soda creates an alkaline environment that is inhospitable to mushrooms. Mushrooms typically die within one to three days of exposure to an alkaline environment.
To use baking soda to kill mushrooms, you can create a solution by mixing three to four tablespoons of baking soda with one gallon 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 affected areas of your lawn. Alternatively, you can sprinkle baking soda directly over the soil and then water it to dissolve the baking soda.
When using baking soda to adjust the soil's pH, it is important to be cautious. Excessively high levels of baking soda can cause a buildup of salts in the soil, which can be toxic to plants and lead to wilting, stunted growth, and eventually, plant death. It is also important to examine your soil's pH before applying baking soda, as using too high of a concentration can kill your lawn. Additionally, the effects of baking soda are not permanent, and mushrooms may reappear once the soil conditions improve.
By following these instructions and being mindful of the potential risks, you can effectively use baking soda to adjust your soil's pH and kill unwanted mushrooms in your lawn.

Dig up decomposing wood
Mushrooms are nature's decomposers, and they play a vital role in the ecosystem by breaking down dead organic matter and returning nutrients to the soil. However, they can be a nuisance in gardens and lawns, especially if you have children or pets who might accidentally ingest them. If you notice mushrooms sprouting in your garden, it is essential to take action to prevent their spread.
One effective way to get rid of mushrooms is to remove their food source. Mushrooms often feed on decomposing wood, so by digging up and disposing of any decaying wood, stumps, or roots in your garden, you can eliminate their primary food source and discourage their growth. This method may be labour-intensive, especially if you have a large garden with multiple mushroom clusters. Still, it is a natural and environmentally friendly approach that does not involve the use of chemicals.
When removing decomposing wood, it is important to wear gloves and a mask to protect yourself from any potential spores or allergens. Use a shovel or garden fork to carefully dig around the affected area, ensuring you remove all traces of decaying wood. It is also crucial to improve the air circulation in the area, as mushrooms thrive in stale, moist environments. You can achieve this by aerating the soil with an aerator or garden fork to allow more air to reach the roots and prevent moisture buildup.
Additionally, you can add nitrogen-rich fertiliser to the soil, which will accelerate the decomposition of organic matter, leaving the mushrooms without a food source. Follow the instructions on the fertiliser package for proper application methods and safety precautions. It is recommended to apply one pound of nitrogen for every 1,000 square feet of lawn annually.
By combining these methods—digging up decomposing wood, improving air circulation, and using nitrogen fertiliser—you can effectively kill mushrooms and prevent their recurrence in your garden or lawn. Remember to be vigilant and act quickly when you spot new mushroom growth to maintain a healthy and fungus-free outdoor space.
