Remove mushrooms from the ground by pulling them out or digging them up
Mushrooms in your lawn can be an eyesore, and may be harmful if they are poisonous. Most of the mushrooms we see in our yards and gardens are harmless, but it is important to identify the mushrooms growing in your yard and remove any toxic ones. Mushrooms often grow in shady, damp spots with poor drainage, so it is important to address these issues to prevent mushroom growth.
To remove mushrooms from the ground, it is best to act quickly as soon as you see the caps appear. If you leave them for too long, they will release spores, which will lead to more mushrooms. You can pull them out of the ground by hand, or use a spade or shovel to dig them out. Put the mushrooms in a plastic bag as soon as you pull them out, and tie the bag tightly before disposing of it in a trash can or incinerator. This will prevent the mushrooms from spreading spores across your lawn.
You can also mow or rake over the mushrooms, but this may increase the chances of them spreading spores. If you use your hands to remove mushrooms, wear gloves to protect yourself in case the mushrooms are poisonous. You can also dig out mushroom clumps using a shovel or garden trowel.
While removing mushrooms from the ground will cut down on future mushroom reproduction, it will not solve the problem entirely, as the mycelium, or underground network of fungus threads, will remain. To completely get rid of mushrooms, you will need to address the underlying growing conditions.

Dispose of removed mushrooms in a plastic bag to prevent spores from spreading
Mushrooms are the fruits of the fungus world. They help break down organic material in the lawn, deposit nutrients into the soil, and improve water retention. However, they can be dangerous if consumed by children or pets, so it is important to know how to get rid of them.
To prevent the spreading of mushroom spores, it is recommended to dispose of removed mushrooms in a plastic bag. Put on a pair of gloves and pull the mushrooms out of the ground by hand or use a spade to dig them out. Ensure you remove the entire mushroom, not just the head, as this will prevent further growth. Place the removed mushrooms directly into a plastic bag to prevent the movement of spores. Seal the bag tightly to avoid any spores becoming airborne and dispose of it in a bin.
It is important not to toss the mushrooms into a compost pile, as this will encourage further growth. Instead, discard the mushrooms in a trash can or incinerator. Additionally, you can pour water and a few drops of dish soap into the holes where the mushrooms were removed to prevent further growth.
To prevent mushroom growth, you can improve the drainage in your yard, clean up decaying organic matter, and increase sunlight exposure.

Improve soil drainage and sunlight to make conditions less favourable for mushrooms
Mushrooms thrive in environments with poor soil drainage and low sunlight. Improving soil drainage and increasing sunlight exposure can make conditions less favourable for mushrooms.
Improving Soil Drainage
Soil with poor drainage is characterised by smaller pores that retain water for longer periods. This can negatively impact root health as excess water displaces oxygen. To improve soil drainage, you can:
- Avoid soil compaction by reducing foot traffic and refraining from working on wet soil.
- Use techniques like tilling, spading, trenching, or aeration to break up hardpans or impermeable layers.
- Incorporate organic matter, such as compost, to improve soil structure and increase soil aggregation, creating more pore space for water and air.
- Utilise cover crops, especially in vegetable gardens, as their roots can help break apart compacted soils and increase organic matter content.
Increasing Sunlight Exposure
While mushrooms are typically associated with shady spots, light plays a crucial role in their development. Increasing sunlight exposure can deter mushrooms by disrupting their preferred growing conditions. However, it is important to note that different mushroom species have varying light requirements, and some prefer low light or even complete darkness.
For areas where mushrooms are undesirable, consider ways to increase natural light exposure, such as trimming branches or shrubs that create excessive shade. If artificial lighting is an option, LED lights or fluorescent tubes can be used to provide controlled and consistent illumination.

Apply nitrogen fertiliser to the soil to deter mushrooms from growing
Mushrooms are a type of fungi that can grow in a variety of environments, including lawns. While they are generally not harmful and can be beneficial to the health of your lawn, there are several ways to prevent or deter mushrooms from growing, including the application of nitrogen fertiliser to the soil.
Nitrogen fertilisers can be effective in deterring mushrooms from growing because mushrooms require nitrogen to thrive. By applying nitrogen fertiliser, you can speed up the decomposition of organic matter in the soil, leaving the mushrooms with nothing to feed off of. It is important to note that simply adding nitrogen to the soil may not be enough to deter mushrooms, as they can also thrive in high-nutrient soils. Therefore, it is recommended to combine nitrogen fertiliser with other methods, such as improving drainage and airflow, to effectively deter mushrooms.
When applying nitrogen fertiliser to deter mushrooms, it is essential to use the correct type and amount. It is recommended to use a quick-release, inorganic nitrogen fertiliser. Avoid using slow-release or water-soluble nitrogen fertilisers, as these may not be effective in deterring mushrooms. The amount of nitrogen fertiliser to use will depend on the size of your lawn. As a general guideline, you can use 1 pound (453.59 grams) of nitrogen for every 1,000 square feet of lawn. Additionally, consider adding some phosphorous and potassium to your fertiliser mix. A ratio of 3 parts nitrogen, 1 part phosphorous, and 2 parts potassium is recommended by the Missouri Botanical Garden.
It is important to be cautious when applying nitrogen fertiliser to your lawn, as over-fertilisation can negatively affect the health of your grass. Make sure to follow the fertiliser package directions and apply the fertiliser according to the recommended schedule for your area. Additionally, be mindful of the placement of the fertiliser, ensuring that it does not come into contact with desired plants or grass, as it could damage or kill them.
While applying nitrogen fertiliser can help deter mushrooms, it may not completely prevent their growth. Mushrooms can spread through spores, which can be blown by the wind from other areas. Therefore, it is essential to combine nitrogen fertiliser application with other preventative measures, such as improving drainage, reducing shade, and removing organic debris, to create an environment that is less favourable for mushroom growth.

Use natural fungicides like horticultural vinegar or a mixture of soap and water
Horticultural vinegar can be used to kill mushrooms in your yard. However, it is important to note that this method can harm surrounding plants, so it should be applied with precision. You will need to use a horticultural vinegar that is more concentrated (usually 30-50%). Follow the manufacturer's instructions for dilution, and be sure to wear gloves and eye protection as concentrated vinegar can burn your skin. After applying the vinegar, leave the mushroom to die, or dig it up and respray the spot for extra prevention.
Another natural alternative to fungicides is a mixture of soap and water. This can be used to kill and prevent the regrowth of mushrooms. Mix 2 to 3 tablespoons (29.6 to 44.4 ml) of dish soap with 2 to 3 gallons (7.57 litres) of water. Poke holes into the soil around the mushrooms using a shovel, trowel, or screwdriver, and pour the mixture into the soil. It is recommended to aerate the soil around the mushrooms before applying the liquid to ensure proper drainage. Within 24 hours, the mixture will start working to kill off the unwanted fungi. For a large colony of mushrooms, you may need to repeat the process.
In addition to these natural fungicides, you can also prevent mushroom growth by improving drainage in your yard and removing decaying organic matter. Mushrooms thrive in dark, damp, and poorly drained spots with high levels of nitrogen from decaying organic material. By eliminating standing water and improving aeration, you can quickly get rid of mushrooms.
