Destroying Mushrooms: Effective Ways To Kill Them Off

how to kill a mushroom

Mushrooms can be a nuisance, especially when they start to invade your lawn or garden. While some mushrooms are edible, others are toxic and can be dangerous if ingested by children or pets. If you're looking to get rid of unwanted mushrooms, there are several methods you can try. Firstly, you can pull them out by hand, wearing gloves to protect yourself. However, simply plucking the mushrooms may not kill them, as they have a large network of threads underground. To prevent further growth, you can try changing the pH level of the soil using baking soda or dish soap. Another method is to use a natural fungicide, such as vinegar, which will kill the mushrooms but may also affect surrounding plants. Alternatively, you can use a nitrogen fertilizer to deter mushrooms by depriving them of their food source. For mushrooms growing in your bathroom or on rocks, you can try physical removal or use products like kalk paste or frank's f-aiptasia.

Use vinegar

Mushrooms are a type of fungi that thrive in moist conditions. While they are beneficial to your lawn, helping break down dead material and returning nutrients to the soil, they can be a nuisance, especially if they are toxic. Simply plucking mushrooms is not enough to kill them, as they are much larger beneath the surface of the soil. To kill mushrooms, you can use vinegar, an effective natural fungicide.

The first step is to put on gloves to keep potentially poisonous spores off your hands. Then, pull each mushroom out of the ground by hand, ensuring you get the entire mushroom by the root. Put the mushrooms in a plastic bag and discard it to prevent the mushroom spores from spreading.

Next, create your own fungicide by combining vinegar and water in a spray bottle. Mix 1 part vinegar with 4 parts water. Mist the soil where the base of each mushroom was sticking out of the ground. Continue doing this for 5 days to ensure that the mushrooms don’t grow back. Be careful not to spray the vinegar solution on your plants or grass, as vinegar can kill them.

Alternatively, you can mix 2 tablespoons of baking soda with 2 cups of water and spray this solution directly onto the mulch where mushrooms are growing. Baking soda will eat away at the mushrooms and change the pH of your soil, making it harder for mushrooms to live.

Mow or rake them

Mowing or raking mushrooms is a quick way to remove them from your lawn. However, it is important to note that this method can increase the chances of spores spreading across your lawn, leading to more mushrooms. Therefore, it is recommended to mow or rake mushrooms as soon as they appear, before they have a chance to release their spores.

When using a lawnmower to remove mushrooms, it is best to collect or rake the grass clippings afterward to prevent thatch buildup. Thatch is a layer of living and dead grass on the soil surface that inhibits water movement and air circulation, providing an ideal environment for mushrooms to grow. By removing the grass clippings, you reduce the organic matter that mushrooms feed on and make the conditions less favourable for their growth.

Raking is another effective way to remove mushrooms from your lawn. It is important to use a power rake for this purpose, which can be rented from hardware or home improvement stores. Once you have finished power raking, use a regular rake to sweep up the debris and prevent it from becoming a food source for mushrooms.

To reduce the chances of spreading spores while raking or mowing, it is recommended to wear gloves and place the mushrooms in a plastic bag for disposal. This prevents spores from sticking to your hands and spreading to other parts of the lawn. Additionally, it is crucial to dispose of the mushrooms properly by tying the bag tightly and throwing it into a trash can or incinerator.

While mowing and raking can be effective in removing mushrooms, they may not completely eliminate the problem. Mushrooms will continue to appear as long as there is organic matter in the soil for them to feed on. Therefore, it is essential to address the underlying cause by improving drainage, removing decaying matter, and creating drier conditions to make your lawn less favourable for mushroom growth.

Apply nitrogen fertiliser

Mushrooms are typically a sign of healthy soil, but they can be a nuisance when they pop up in your lawn or garden. While it may seem counterintuitive, applying nitrogen fertiliser can be an effective way to get rid of mushrooms without killing your grass or plants.

Nitrogen fertiliser speeds up the growth of mushrooms, causing them to move through their lifespan quicker and disappear faster than they would naturally. It also accelerates the breakdown of organic matter, reducing the food source for mushrooms. This strategy is particularly useful if you have a fairy ring mushroom infestation. This type of mushroom grows in circles on your lawn and creates a thick fungal mat, which can cause drought stress for the grass and make it more susceptible to diseases.

To effectively use nitrogen fertiliser to kill mushrooms, follow these steps:

  • Identify the type of nitrogen fertiliser to use: Choose a quick-release, inorganic nitrogen fertiliser. Avoid slow-release or water-soluble nitrogen fertilisers as these will not have the desired effect.
  • Determine the correct amount of nitrogen fertiliser to apply: For every 1,000 square feet of lawn, you will need approximately 1 pound (453.59 grams) of nitrogen. You can also use a rate of 1/2 to 3/4 pound of actual nitrogen per 1,000 square feet, depending on the nitrogen content of the fertiliser.
  • Apply the nitrogen fertiliser to your lawn or garden soil: Spread the nitrogen fertiliser evenly across the affected area, following the product's instructions for the best results.
  • Repeat annually: Plan to apply nitrogen fertiliser once a year to deter mushroom growth.

Additionally, consider adding some phosphorous and potassium to enhance the effectiveness of the nitrogen fertiliser. A good ratio to follow is 3 parts nitrogen, 1 part phosphorous, and 2 parts potassium.

By applying nitrogen fertiliser, you can effectively kill mushrooms and restore your lawn or garden to its former glory.

Use baking soda

Baking soda, or sodium bicarbonate, is an effective agent for killing mushrooms. It is a safe, natural, and non-toxic remedy that is readily available in most kitchens. Baking soda works by changing the pH of the soil to alkaline, creating an unfavourable environment for mushrooms, thus impeding their growth.

To use baking soda to kill mushrooms, create a mixture of two tablespoons of baking soda and one gallon of water. Stir the solution until the baking soda is completely dissolved. This mixture can be sprayed or poured over the mushrooms and the surrounding soil. Ensure the soil is well-aerated to allow for proper drainage.

It is important to note that while baking soda is effective in killing mushrooms, it may not provide a lasting solution. The soil conditions may improve, and the mushrooms could return. Therefore, repeated applications may be necessary to control mushroom growth effectively.

Additionally, when using baking soda, be cautious not to overuse it, as too much can raise the pH of the soil to a level that is unfavourable for grass growth. It is recommended to alternate between baking soda and vinegar sprays to keep the pH of the soil neutral.

Baking soda is a preferred method for many homeowners as it is easily accessible, safe, and effective in disrupting mushroom growth without causing harm to humans, pets, or the surrounding environment.

Pluck and dispose of them

Mushrooms can be a nuisance, especially if you have children or pets, and they can be a source of concern if they are toxic. Simply plucking mushrooms does not kill them, but it is an effective way to control them.

Firstly, put on some gloves to protect yourself, as some mushrooms are poisonous. Then, as soon as you see the caps appear, remove the mushrooms from the ground. If you leave them for too long, they will release spores, which will lead to more mushrooms. When you see mushrooms appear, simply pull them out of the ground. You can also try mowing or raking over the mushrooms, but this will increase the chances of them spreading spores across your lawn.

Dispose of the mushrooms properly. Do not toss them into your compost pile. Instead, keep a plastic bag with you, and put them into the bag as soon as you pull them out of the ground. Put the mushroom caps in a plastic bag and discard them to keep the mushroom spores from spreading.

Although it is difficult to get rid of mushrooms entirely, this method will reduce future mushroom reproduction.
