How To Get Rid Of Mushrooms In The Yard

Jump to Section

Mushrooms are fungi that usually grow in moist, shaded areas. They can be found growing on all types of organic matter, including grass and leaves. Mushrooms can be detrimental to lawns because they create patches where the grass cannot grow due to a lack of sunlight.

In this article, we describe the different types of lawn mushrooms and how to get rid of them. Let's get started.

Types of Lawn Mushrooms

Lawn mushrooms are classified based on the conditions they need to grow. These conditions can be broken down into five main categories – moisture, sunlight, temperature, pH level, and nutrients. The most common types of lawn mushrooms belong to the “saprobe” category.

Saprobes require low light and thrive in moist areas with rich soil content to survive. They usually start appearing during spring or after a significant rainfall event. With that said, there are also other types of mushrooms that can grow in your yard. These are some of them, typically found in North America:

  • White mushroom (Agaricus bisporus)
  • Meadow mushroom (Agaricus campestris)
  • Pinkgill (Entoloma roseum)
  • Chanterelle (Cantharellus cibarius)
  • Shaggy mane (Coprinus comatus)

How to get rid of mushrooms in the yard

There are many ways to get rid of lawn mushrooms. All the methods can be done at home without spending too much money. Let's look at these methods in more detail.

Method 1: Removing Lawn Mushrooms with a Shovel

Removing lawn mushrooms using a shovel is easy and cheap. This method is best used for small patches of mushroom growths in the yard, especially if they are near the edges or boundaries of your property. This way you can keep the rest of the yard free from mushrooms without too much effort.

Use a spade to dig up mushrooms from their base. Make sure you remove all parts of the mushrooms from underneath the soil including their roots and underground stems (rhizomorphs). The more thorough you are, the better because these rhizomorphs will spread to other areas unless removed thoroughly. They can grow even larger than mushrooms visible at surface level. If you don't want to dig, use a spade and carefully remove the mushroom instead.

Keep track of where you have dug up because it will be easier for you to notice new mushrooms as they grow. If you don't know where the new growths are during your next maintenance session, just check all-around and start digging up those possible roots. 

Method 2: Removing Lawn Mushrooms with Fungicide

Removing lawn mushrooms using fungicide is also easy but this method can cost a little more money because most commonly used fungicides are not cheap. Fungicides containing myclobutanil or propiconazole work best against lawn mushrooms by preventing them from growing in that specific area. You need to spray these chemicals around the growths and on the ground slightly beyond their visible area to get rid of mushrooms. If possible, spray fungicide in dry conditions when there is no rain or irrigation expected for at least two days.

Method 3: Removing Lawn Mushrooms with Salt

Removing lawn mushrooms using salt can be used as an alternative if you do not want to use chemicals for whatever reason. To remove these fungi without spending too much money, just sprinkle salt all around the mushroom growths until they are fully covered by it. Do not dig up these mushrooms because this method does not require doing so – instead, just leave them there and wait for a couple of days until they rot away completely. This method only works if your type contains high levels of potassium in its cells.

However, do not sprinkle salt on chanterelles because they are very sensitive to the salt content in the soil. If you happen to have these kinds of lawn mushrooms sprouting around your property, just remove them carefully using a shovel instead without applying any chemicals or salt.

Fertilize your lawn to promote healthy grass growth and discourage fungi  ​growth

Fungi will thrive in moist, shady areas with rich soil content to survive. Lawns that are fertilized regularly tend to have better growth rates and overall health because they can withstand fungal infestations better compared to lawns without any fertilizer. Fertilizers also contain chemicals like iron and phosphorus which make the grass stronger and more resistant to fungus damage. The application of organic compost is also effective in discouraging mushroom growth in yards because it promotes healthy soil structure by encouraging plant-microbe activity below ground level. Regular application of nitrogen-rich fertilizers like blood meal will also help discourage fungi from growing around your property.

All these methods can be done at home without spending too much money, but if you want the fastest and easiest method to get rid of mushrooms on the lawn, you should hire a garden service that specializes in removing fungi. Gardeners who do this for a living can efficiently remove these fungi from your yard quickly and without too much effort.

If there is nothing wrong with the rest of your lawn and you just want to get rid of mushrooms, then it will be easier to use one of the cutting methods we explained above because they don't require using chemicals or salt before discarding them.

Eliminating debris from the lawn

Removing debris from lawns is also a necessity to remove fungi because it can cause the soil beneath the grass to become moist, which in turn allows more fungus growth. Remove leaves or any other organic debris you find on your lawn regularly so they won't pile up and create new areas for fungi. Do this by raking leaves off your grass properly after windy days so they don't get crushed underneath the weight of whatever falls on top of them.

Mowing Lawn Properly

Taking care of your lawnmower will help it work efficiently while cutting down your grass because clippings that are too long will only decompose quickly in your yard after falling at different heights. This will result in uneven cuttings that can lead to fungus growth because there are parts that are too wet or dry, depending on the type of grass you have.

Just like how having a clean and sharp lawnmower blade can help your mowed grass look cleaner and more evenly cut, it also has the same effect on fungi. Cutting down these fungal structures at their base will eventually lead to them dying completely after several weeks without any moisture from rain or irrigation.

This can be done by using either a lawnmower or weed whacker. However, there is a huge chance it will damage your yard's blades of grass if the fungi are located too close to them.

Growing other garden items in your yard

Once you've gotten rid of mushrooms, you can grow other things in your yard. For example, if you want to grow cosmos in your yard in place of the mushrooms you removed, you can do so easily. Cosmos will grow well in places with moist soil because they are also not too fond of dry environments. Plant cosmos seeds right after removing all the fungi from your yard and water them by hand or with a garden hose to give them a good head start before letting nature take its course.

Growing morning glories is also a good idea if you want to discourage mushrooms from growing in your yard. Morning glories are flowers that are perennials that have deep roots, which means they are great for removing excess water from the soil. This can be very important for encouraging fungus growth because excessive moisture encourages plagues of fungi rather than healthy plant growth.

You just need to buy morning glory seeds or saplings and put them on a sunny area of your lawn with no shade so these plants have enough sunlight exposure during the day. The best time to do this is in early autumn so you won't have to worry about these flowers dying once winter comes around again.

What are the most commonly used fungi fungicides for getting rid of mushrooms in the yard?

Several fungicides can be used for this purpose. You can use any product containing Dimethomorph, Difenoconazole, Fludioxonil, or Propiconazole. Apply it using a sprayer before you see the first sign of mushrooms to keep them away.

What is the best time to get rid of mushrooms in the yard?

Early in the morning is the best time for that. All these fungicides are active during humid conditions only so it is better to get rid of mushrooms before it starts to get sunny or after it gets completely dry.

How do I use a fungicide to get rid of mushrooms in the yard?

Do not spray the fungi fungicide directly on your plants. You should dilute it with water before applying. Don't apply it more than once every 7 days so that the pests won't become resistant to it.

It is better to avoid spraying in windy conditions so that you don't damage other plants around your garden. Before using any chemical always read the instruction for getting information concerning storage, application, and personal protective equipment required. 

Keep in mind the following:

  • Always store it properly and away from pets or kids' reach. If you are not sure about what type of product you need or how to use then ask professionals for help.
  • Always wear a mask, goggles and clothes which fully cover your body and spray only when necessary. If you use a garden hose to apply the fungicide then always protect your skin from direct exposure to it by wearing gloves or special clothes that cover your arms and legs at least.
  • Always follow the instructions on the label if you're using a chemical for this purpose.

Final thoughts on How to get rid of mushrooms in the yard

In conclusion, there are many ways to get rid of mushrooms in the yard. The best way is to use a fungicide along with gardening techniques to prevent further growth of mushrooms. Another great idea is to plant grass seed if the mushroom remnants are located on bare ground.

If you still cannot figure out how to get rid of mushrooms in your yard or garden after trying all these methods, it may be time to call an exterminator and let them take care of it for you.
