Mushrooms are a sign of a healthy lawn, but you can prevent them from growing in your grass
Lawn mushrooms thrive on moisture, decaying wood, and dead plant material, so areas with poor drainage or buried stumps encourage their growth in your grass.
Mushrooms benefit your lawn by breaking down tough organic matter, helping plants absorb nutrients and water, and signaling healthy soil conditions in your yard.
You can prevent mushrooms by improving drainage through aeration, removing stumps and dead roots, dethatching your lawn, and trimming trees to reduce shade and moisture.
Hiring a local lawn care professional provides expert help with aeration, dethatching, and stump removal, keeping your lawn healthy and mushroom growth under control.
Wondering why there are mushrooms growing in your grass? In areas with poor drainage, fallen branches, or stumps, mushrooms will tend to flourish. For the most part, mushrooms are friendly and a good sign that your soil and plants are healthy.
But if you don’t like their appearance, you can improve your lawn’s drainage and remove dead wood to keep them to a minimum. Here are the reasons you might find mushrooms in your grass and when to hire a local lawn care pro or tackle mushroom control yourself.
Yard mushrooms can sprout anywhere with decaying or dead wood, plant material, and moisture. These locations can include your lawn, especially if you have areas with poor drainage, empty space from a previous stump, shrubs, or fallen branches. These elements can feed mushrooms the wood material they need to thrive. Since mushrooms are spread by their spores, they can be introduced by wind or tracked in on shoes or paws.
Besides being a sign of good soil health, mushrooms and other fungus can help plants survive stress, including drought and disease. Fungi can intermingle with plant roots and help plants communicate through the dissemination of chemical and electrical signals, plus help plants absorb water and nutrients from the soil. Mushrooms can also break down tough materials like stems, sticks, and dead tree roots that can cause thatch on your lawn and create tough growing conditions for future plantings.
Since mushrooms thrive in environments with lots of moisture, shade, and decaying plant material, preventing them is as simple as limiting these elements in your lawn. If you need help with your chosen mushroom removal method, don’t hesitate to hire a local lawn care professional for assistance.
You can improve drainage in your yard in a few different ways. You can aerate your lawn to allow water to absorb more quickly into the soil, with the help of a professional lawn aeration service. Another option is to add gravel to the edges of your lawn where rainwater might collect. For more time- and labor-intensive projects, you can consider methods like regrading your lawn.
Trimming trees and shrubs that shade a particularly moist area of your lawn can help discourage mushroom growth. Since sunlight will help to dry out a damp patch, this method can be a win-win for mushroom mitigation.
Removing the leftover stumps from dead trees or shrubs and the dead roots will limit the food sources for mushrooms in your grass. If you have an area of particular concern where mushrooms repeatedly grow, it’s likely that there’s some decaying wood under the soil.
Removing dead plant material like stems and grass clippings from your lawn will reduce food sources for mushrooms. Dethatching your lawn can also improve drainage in your soil, limiting the moisture available to mushroom spores on the lawn’s surface.
Wood chips used as mulch can sometimes feed mushrooms and contribute to their growth. Limiting wood chips and especially keeping them clear of damp areas can help keep mushroom growth at bay.
Since the tops of mushrooms are only the reproductive parts of the fungus containing the spores, you likely won’t kill off mushrooms by plucking them. However, the part that lives above ground is the obtrusive part for a grass lawn, so it tends to be the most important part to get rid of. Follow these methods for removing mushrooms from your lawn.
You can remove mushroom tops by mowing over them. If you need to mow the lawn anyway, this method will work great, and it will take several months for new mushrooms to grow. Using a robotic mower can nip off the mushrooms before they get big enough to cause a problem.
Allowing mushrooms to shrivel in the sun or even encouraging some drainage after they sprout to dry them out can help kill them. Allowing sunlight to flood the area is a great natural way to get rid of mushrooms growing in your grass.
Picking mushrooms when you see them is sufficient to control mushrooms sprouting on your lawn after a rainstorm. Since mushroom spores spread by wind, there’s no way to eliminate them, but snapping off the tops will keep them under control.
Wonderful. I am going to have them remove and replace my driveway in the spring.
All Star Paving and SealingWe were having 2”x 2” tile installed . There was a small installation error and the new additional replacement tile was from a different lot and the colors didn’t match. Joe assured us that he would rectify everything , which he did without hesitation. We decided to go with the 18” x 36” tile...
CarifaTileWe had a 20+ year old landscape lighting system that needed replacement. Midwest Lightscapes worked with us to design a much improved lighting system, lighting the exterior of the house and the back yard. Installation of the 45 light system took one and one-half days, and went very smoothly....

They show up and they did take us on as a client which seems to be a problem with other lawn care providers. We have multiple properties and this one was located close to downtown and no one really wants to mess with it.
The worker came out when he was supposed to come. He informed me he would honor the Angie's List deal, but would not do any more work for me since my son in law owns lawn care company as well, even though they do not do the same type of work. He said he did not feel comfortable giving me...
Bello Giardino LLCE & L Lawn Care was super. They were very responsive before and after service. They were efficient and were able to complete the job within 1 day. I have had concern about one section of sod - the owner was pro-active and did a visit to evaluate. I have no doubt they will stand behind...
