Are mushrooms bad for your lawn? Mushrooms growing in your yard are a sign that your property has many organic materials that the mushrooms break down to make your soil more productive.

Keep reading to learn why mushrooms are growing on your lawn and the best ways to get rid of them and keep them from growing again. 

Should you remove mushrooms from your lawn?

Mushrooms growing on your lawn is not a bad sign necessarily. It can be an indicator that your yard has productive soil and can hold moisture well. However, mushrooms are more of an above-ground representation of beneficial fungi growing in your yard’s soil. Getting rid of them is a temporary fix that has more aesthetic benefits than anything else. 

Why are you getting mushrooms on your lawn? 

Two key factors result in mushrooms growing on your lawn: moisture and organic matter. There can be more severe problems underlying why mushrooms are growing, but it is not very common. 

Moisture

Moisture can build up because of poor drainage, too much shade, or excessive rainfall. Don’t be surprised if you find mushrooms popping up on your lawn after a rainfall. After a few days, they should go away on their own if no rain and enough sunlight is hitting your yard.

Organic matter

Organic matter can come from leaving grass clipping on your lawn after mowing or a large number of leaves falling from trees on your property. Removing dried leaves and grass clippings can not only keep mushrooms from growing up but will also keep your lawn clear enough that you can easily spot any mushrooms starting to grow and get rid of them. 

Do mushrooms destroy grass?

Mushrooms will not destroy your grass but have the opposite effect. Mushrooms break down organic material on your lawn, providing a food source for your grass, making it healthier. However, it can take a few years for the mushrooms to impact the growth of your lawn correctly, so there is no immediate benefit nor detriment. 

How to get rid of mushrooms on your lawn

While having mushrooms on your lawn is not bad for your yard, you may decide that you want to get rid of the mushrooms and keep them away. Here are some quick steps to take to free your lawn of mushrooms without damaging your grass.

Remove existing mushrooms

It’s best to start will a clean slate. The most efficient way of getting rid of mushrooms that have already grown and without spreading spores around your yard that could develop into new ones is to pick them by hand and put them in a sealed bag. It’s essential to have them in a sealed bag to ensure further that no spores get out.

Nitrogen fertilizer

Nitrogen fertilizer helps organic material decay faster, which takes away the mushrooms’ food source. Add 1 pound of fertilizer per 1,000 square feet of your lawn. 

Remove mushrooms clusters and debris

Mushrooms will cluster where there is the most food for them to thrive. Digging up those clusters will enable you to find the source that encourages mushrooms to grow and remove them. This source will likely be something like decaying wood which provides carbon and moisture. 

Soup and water

Pouring soapy water into small holes around the mushrooms will kill the mushrooms at the roots. You can mix a tablespoon of dish soap with about a gallon of warm water. Using a screwdriver, punch holes into the soil, then pour the water in. Soapy water can also be a great pet-friendly way to get rid of mushrooms since the diluted soup doesn’t have harsh chemicals like fungicides. 

Adding drains

Most of the time, the reason mushrooms are growing on your lawn is because there is too much moisture. If you find that rainwater is sitting on your property for at least a day after the rain has stopped, then you should consider adding drainage to help redirect the water out of your yard.

Remove organic materials

Leaving grass clippings from mowing your grass and dried leaves from nearby trees on your lawn will add to the organic material the mushrooms are feeding on. Raking and mowing your lawn regularly will take away that food source and keep mushrooms from reappearing. 

Waiting

It might not be the most efficient way of getting rid of mushrooms, but they will go away with time as long as there isn’t anything for them to break down. Mushrooms won’t do any harm to your lawn, so as long as you don’t mind having a few for a little while, they will eventually go away on their own. 

Are mushrooms bad for pets?

For pet owners, getting rid of mushrooms in your lawn could be a matter of looking for a way to keep your furry friend safe. While most mushrooms are harmless, there are some poisonous mushrooms that you don’t want to leave in your yard. Keeping all mushrooms away is the best way to ensure they are safe. 

Are mushrooms bad for children?

Generally, mushrooms that grow in lawns are harmless and poisonous varieties rarely grow. However, there is always a chance that there could be harmful types growing without you being aware. If you have children, it’s probably best to remove any mushrooms from your lawn and do what you can to prevent them from growing again. 

Should you use a fungicide?

Fungicides are primarily for instances where there is a severe fungus infection causing brown patches on your lawn. In most cases, growing mushrooms up is not a sign of severe disease, so using a fungicide is not necessary. 

However, if you suspect that the mushrooms are there as a sign of underlying fungi issues, you might want to investigate further and consider the best course of action for your lawn.
