Mushrooms in your lawn can be unsightly and even dangerous, especially if you have children or pets. While mushrooms indicate that your soil is healthy, they can be a nuisance and a hazard. To kill mushrooms in your lawn, you can try several methods, including physical removal, changing environmental conditions, and using natural or commercial fungicides. Mushrooms thrive in damp, shady conditions, so improving drainage, sunlight exposure, and airflow can help prevent their growth. Additionally, natural remedies such as vinegar, baking soda, and coffee grounds can alter the pH of the soil and make it less hospitable for mushrooms. However, it is important to exercise caution when using any substance, as some can be harmful to your lawn and the environment.

What You'll Learn
Pick mushrooms by hand and dispose of them properly
Mushrooms in your lawn are a sign of healthy soil, but they can be unsightly and may be toxic to children and pets. If you're concerned about mushrooms in your lawn, the simplest way to remove them is to pick them by hand.
When picking mushrooms, it's important to wear sanitized gardening gloves to prevent the spread of spores. Pick the mushrooms when they are young, before their caps have opened. If you're unsure, pick up any mulched leftovers. Place the picked mushrooms directly into a plastic bag and seal it tightly before disposing of it in the trash. Do not put the mushrooms in your compost, as they may continue to spread spores.
To discourage further growth, you can add a few drops of dish soap and water to the stems of the mushrooms before discarding them. You can also mix one to two tablespoons of baking soda into one litre of water and pour this solution over the areas where mushrooms have been removed. Another option is to mix one part vinegar with four parts water and spray this solution onto the mushrooms.
While it is possible to remove mushrooms by hand, this method will not solve the underlying problem, as the mycelium, or underground network of fungus threads, will remain. To prevent mushrooms from growing in the first place, you should address issues with drainage, sunlight, and organic matter in your lawn.

Mow over mushrooms and rake them away
Mushrooms in your lawn can be unsightly and even dangerous, especially if you have children or pets. While they are a sign of healthy soil, you may want to get rid of them.
Mowing over mushrooms is one way to deal with them. This method will not remove the entire fungus, but it will help to get rid of the fruiting part. Be sure to mow over the entire area where mushrooms are growing and then pick up and discard the mushroom pieces immediately. You can also rake over the area to remove any remaining mushroom spores and prevent them from spreading. However, raking may not be enough to stop mushrooms from growing back, as the main body of the fungus lives underground.
To effectively remove mushrooms from your lawn, you will need to dig out the entire fungus, which can be labour-intensive. Use a shovel or spade to dig out the cluster of mushrooms, digging at least 12 inches down to remove as much of the fungus as possible. You can also pull mushrooms out individually by hand or cut them with a knife.
To prevent mushrooms from growing in the first place, you should improve drainage and avoid overwatering your lawn. Mushrooms thrive in damp, dark environments, so increasing sunlight and improving air circulation can also help deter them. Remove any decomposing matter, such as wood chips, branches, and pet waste, that mushrooms could feed off. Finally, keep your grass healthy by maintaining your lawn all year round.

Use a natural fungicide, like vinegar
Mushrooms in your lawn can be an eyesore and may even be harmful, especially if you have pets or young children. While they indicate that your soil is rich and of good quality, you may want to get rid of them.
A natural fungicide, such as vinegar, can be used to kill mushrooms in your lawn. The acetic acid in vinegar is incredibly fast-acting and will kill the mushrooms within a few hours. However, it will also kill anything else it comes into contact with, so exercise caution when using this method.
To make a vinegar-based fungicide, mix one part vinegar with four parts water in a spray bottle. Apply the solution directly to the mushrooms. It is best to spray early in the morning or late in the evening so that less water evaporates and the solution has more time to act on the mushrooms. Repeat the application every few days until you notice a reduction in mushroom growth.
In addition to using a natural fungicide like vinegar, you can also take preventative measures to stop mushrooms from growing in the first place. Mushrooms thrive in damp, dark environments with dead organic matter, such as patches of lawn covered in leaves or areas under trees with soggy leaf mould. They also require shade to grow, so trimming back branches on nearby trees or shrubs can help reduce their growth.
By combining the use of a natural fungicide with preventative measures, you can effectively kill and prevent mushrooms from growing in your lawn.

Avoid overwatering and improve drainage
Mushrooms thrive in damp, dark environments, so it's important to avoid overwatering your lawn and improve its drainage to prevent them from growing.
To avoid overwatering, it's recommended to water your lawn in a way that's suited to its needs. This means watering deeply and infrequently to create a drier environment that is less conducive to mushroom growth. If you have an area where a tree used to stand, even if the stump is gone, the dead roots underground may encourage mushroom growth. Therefore, it's important to keep the area well-raked and aerated to improve drainage. Aeration can be achieved by using a tool called an aerator, which creates holes in the soil to improve air circulation and drainage.
Additionally, you can solve underlying issues such as poor drainage or lack of sunlight. For example, you can extend your home's downspout, draw a drainage plan, construct a creek bed or a French drainage system, or build a rain garden with plants that thrive in intense moisture. These measures will not only help with drainage but also make your lawn less attractive to mushrooms.
It's worth noting that prevention is key when it comes to controlling mushrooms in your lawn. By adjusting the watering and improving drainage, you can create an environment that is less favourable for mushroom growth and reduce their occurrence in the long run.

Decrease shade by trimming branches
Mushrooms in your lawn can be a cause for concern, especially if you have pets and children. While mushrooms themselves are not a problem, they indicate the presence of fungi that thrive in damp, dark environments. These fungi break down organic matter in your lawn, such as dead leaves, tree branches, animal waste, bark, and grass clippings.
To address this issue, one effective strategy is to decrease the shade in your lawn by trimming back branches on nearby trees and shrubs. Mushrooms favour shaded areas, so increasing sunlight can help reduce moisture levels, creating an environment less conducive to mushroom growth. This simple step can make a significant difference in managing mushroom proliferation.
When trimming branches, focus on areas with dense tree and shrub overgrowth, as these areas are more likely to provide the necessary shade and dampness for fungi to flourish. By thinning out the crowns of trees and shrubs, you can allow more sunlight to penetrate, making it less inviting for mushrooms to take hold.
Additionally, removing decaying organic material from your lawn is crucial. This includes clearing away dead leaves, grass clippings, and any other debris that can serve as a food source for the fungi. By depriving the fungi of their sustenance, you further reduce the likelihood of mushroom growth.
While decreasing shade through branch trimming is a recommended strategy, it is important to recognise that prevention is the key to effectively controlling mushrooms. This may include improving drainage, reducing standing water, and adjusting your watering schedule to allow your lawn to dry out during the day. By making these changes, you can create an environment that discourages mushroom growth and fosters a healthier lawn.
