What Causes Mushrooms in Your Yard?

What Causes Mushrooms in Your Yard

Good environmental conditions are the reason why there are mushrooms in your yard. This is an indication that you have fungi-rich soil and a wet ground condition.

Furthermore, mushrooms usually flourish in dark and damp environments with plenty of decaying matter, such as:

  • Tree stumps
  • Grass clippings
  • Dog or cat poop
  • Tree roots
  • Fallen leaves
  • Decaying twigs, mulch, and more.

However, it’s very important not to confuse lawn mushrooms with edible mushroom species as most of them are poisonous.

How Do Mushrooms Spread?

Mushrooms spread through spores. Spores are the diminutive reproductive cells released by the mushroom and transmitted by the wind. 

Once they land, they begin new colonies of mushrooms. According to a UCLA researcher, mushrooms ‘make’ their own wind. They do so by letting their moisture evaporate, creating water vapor and cool wind around them.

The air and water vapor around them gives spores enough lift to spread out. As a result, the natural wind mushrooms created can bring them four inches up until they land at their destination.

How Do I Prevent Mushrooms From Growing on My Lawn?

How Do I Prevent Mushrooms From Growing on My Lawn

The best way to stop mushrooms from growing on the lawn is by monitoring and controlling your garden condition. To do this, you can do the following:

  • For those mushrooms that just started to grow, you can pull them out. This hinders the spores’ ability to scatter via wind and eliminates the risk of poisoning pets and animals that eat them.
  • As mentioned above, mushrooms feed on organic matters that surround them. Thus, it would be helpful to remove these organic matters that serve as their foods.
  • If your lawn has a thick thatch layer, consider dethatching them to prevent the growth of mushrooms. In addition, mow your lawn regularly and limit the water application to the soil. That way, you won’t be creating ideal environmental conditions for mushrooms to thrive unknowingly. Moreover, make sure to rake away any mushroom remnants to hinder spores from spreading during mowing. 
  • Aeration is also ideal in helping improve drainage and airflow, keeping the soil and grass dry.
  • Cut back also any overhanging limbs as mushrooms love to spout in shaded, damp areas.

How Do I Naturally Get Rid of Mushrooms in My Yard?

To get rid of mushrooms naturally, consider the following:

Organic Waste Removal

You need to remove the decaying matters that serve as their food. This may include:

  • Grass clippings
  • Animal wastes
  • Rotten stumps
  • Decomposing tree branches.

It will also help if you thatch your yard with a thatching rake in removing these organic matters.


Vinegar is a great home ingredient that contains acetic acid, an active ingredient known for its exceptional ability to kill garden mushrooms. To use vinegar:

Step 1: Get a clean spray bottle.

Step 2: Pour four parts of water and one part of white vinegar or horticultural vinegar.

Step 3: Once done, spray it only on the mushrooms to avoid killing your grass and plants.

Baking Soda

Another home ingredient you can use to kill lawn mushrooms naturally is baking soda. Although this item isn’t a fungicide, it can raise the soil’s pH, preventing mushrooms’ growth. 

To apply:

Step 1: Get a gallon of water and mix it with two tablespoons of baking soda. 

Step 2: Make sure the solution is well-dissolved and put the mix in a clean spray bottle. 

Step 3: After that, spray the mixture into the mushrooms and the surrounding soil. This will decrease the growth chances of mushrooms and kill them eventually.

On the other hand, you may sprinkle the baking soda directly into the mushrooms and the soil around them.

How to Prevent Mushrooms From Growing?

To prevent mushrooms from growing, you can use the following methods:

Nitrogen-Based Soil

You can use nitrogen-based soil. This increases the speed of mushroom decay, allowing them to die early than their usual life cycle.

Lawn Aeration

Aerating your lawn is an effective method of preventing mushrooms from growing in less severe cases. This allows water and nutrients to penetrate your soil rather than sit on top of your grass. 

Lawn aeration will keep your grass and soil dry enough not to encourage mushrooms’ growth.

Clean Your Surroundings

Another way to prevent mushrooms’ growth in your yard is to clean your surroundings. Since mushrooms feed on organic matters like rotten stumps, branches, and grass clippings, it’s vital to clean your area from these things.

That way, you can eliminate and control the growth of mushrooms in your yard.

Encourage Sunlight in Your Yard

As stated in this article, mushrooms love to thrive in dark, damp areas. Thus, if you have overhanging tree limbs, pruning them would be ideal. 

If you have large trees, make sure to hire tree care professionals to do the job for you.


In general, mushrooms are harmless. However, there are wild mushrooms that can grow in your yard that could be toxic. 

Aside from that, mushrooms can make your lawn unsightly, so it’s best to pull them out. You can also use the listed methods above to get rid of the mushrooms and restore the pristine look of your garden.
