How To Get Rid Of Mushrooms In My Lawn

In this post, I will be answering your question of how to get rid of mushrooms in my lawn?

Lawn mushrooms are one of the most common landscaping problems. Discovering mushrooms on the lawn can be frustrating for many people who pride themselves on having lush grass. That is problematic because young children will be playing on your lawn. Pets can also become sick as a result of eating poisonous mushrooms. Some mushrooms even stink badly. The most notorious example is “stinkhorns.” 

If mushrooms are left unchecked, the consequence of all of these problems may be multiplied. Moreover, while mushrooms usually will not harm your lawn, their presence can signal potential problems for your grass in the future, and you do not want that. 

But no problem comes without a solution. The issue of mushrooms growing on the lawn can be easily fixed if you know-how.  

The first and most basic thing to understand is what causes mushrooms to grow on a lawn. Mushrooms seem to grow up out of the blue. But this is not the case. What you see is just the visible result of a process going on underground for some time. Lawn mushrooms are a type of fungus. The fungus has the job to help break down decaying organic material. If you look around in an average yard, there are plenty of sources of decaying organic material. Animal waste, old mulch, and grass clippings can not only spread but also feed lawn mushrooms.

Lawn mushrooms are most possibly to be found in damp, shaded and organic waste rich environments. Is it also quite possible that a drainage problem is contributing to the mushroom growth? The organic waste that didn’t get to be removed can also be the cause of mushroom swamp. Maybe some places in your yard are too shady.

It might sound unreal, but mushrooms are helpful to a lawn in most cases. The fungus feeds on its decaying organic matter. It breaks this matter down and makes valuable nutrients available to your grass. But, what might bother you is the unsightliness, toxicity, or smell from mushrooms. There are steps you can take to get rid of them successfully.

This method will not solve the problem. The underground fungus will live on, but it will stunt the mushroom reproduction, at least. Timing is the most important factor here. If you are one day too late, the spores may already have become airborne and grown.

There are further three steps we need to take. These steps have to do more with performing landscape maintenance tasks. They will monitor your lawn to ensure that it is not becoming overly shaded or that its soil is not draining properly. These three steps are the ones most likely to solve the problem you are facing. They consist simply of addressing the three main reasons for mushroom problems:

  • Poor drainage of water
  • The presence of decaying organic matter
  • Too much shade in the yard

To improve the drainage in a lawn that drains poorly, there are two common solutions:

Treating your lawn to aeration can work if you are facing less severe cases. You can rent the equipment from a rental centre. You don’t have to buy the equipment because you won’t need to aerate enough throughout the year to own the equipment.

If the situation is grave, you may need to install a French drain. Facing the decaying organic matter in the yard is largely a matter of cleanliness. For people who consider themselves a “neat freak”, this step is right up their alley. Nobody can ever remove all of the decaying organic matter in their lawn’s soil (nor would they want to), but an honest effort to keep the lawn clean can make a difference in the long run; for example:

Doing spring cleaning in the yard should be your priority every year.

After mowing, leave a small amount of finely shredded grass clippings on the lawn. It is generally a healthy practice for your lawn. You should consider bagging or raking them up if you are wishful of keeping mushrooms from sprouting up.

  • Rake the fallen leaves off the lawn in autumn or remove them with a leaf blower.
  • Try to keep your lawn dethatched.
  • Remove old tree stumps completely as soon as possible.

If large trees surround you, letting more sunlight into your lawn area may not be a good idea. In less extreme cases, this solution is worth trying. You, yourself, may be able to prune small trees. That can make enough difference. For larger trees, you better hire professionals.  

You can also treat your lawn with a fungicide. But it’s not reliable. If you do not address the issues that cause mushrooms to grow in your lawn, there might be the chances that the mushrooms will just come back again.

While mushrooms in the lawn may look unsightly, they can be very beneficial to the lawn. Mushrooms have an extensive root system. It helps the soil retain water. Lawn mushrooms also help to break down organic materials, which further help add nutrients to the lawn. You can eat some types of mushrooms as well. But for that, you will have to seek a piece of professional advice on which kinds of mushrooms are edible.

Once you can answer the question of why are mushrooms growing on my lawn, you can decide whether or not to get rid of mushrooms on the lawn.

What kills mushrooms in your lawn?

First of all, mix 1 part white vinegar with four parts water in a spray bottle. When you are spraying the homemade fungicide, make sure you’re only spraying it on the mushrooms. Vinegar can kill plants and grass as well. 

Why are there mushrooms on my lawn?

It sounds strange, but those mushrooms popping up on your property are most likely fertilizing your lawn. Because fungi break down wood and other dead plant material into nutrients (decomposition) that other plants can use. So, mushrooms or toadstools are a gesture that soil building is going on in your lawn. That is not a bad thing.

Are mushrooms a sign of overwatering?

Rain can provide ideal growing conditions for mushrooms. In addition to all of the rain, overwatering or watering a lawn at night can also be a significant factor in mushrooms growing in your lawn.  Mushrooms are an indication that the soil below your turf is rich in nutrients.

How do mushrooms suddenly appear?

Mushrooms only grow when environmental conditions are as per their demand, such as prolonged periods of wet and humid weather. They cause fungi to set up fruiting structures. Fungi disperse around to new areas via windblown spores. Once the weather dries out, the mushrooms will go away on their own. 


There are a few steps you have to take to make sure you stop the growth of mushrooms. First of all, rake your grass clippings. Secondly, dethatch your lawn or probably replace the old mulch. It will also help reduce the decaying organic material that encourages mushrooms to grow in the lawn
