Reasons Why Mushrooms Are Growing in Your Yard
Healthy Soil
Mushrooms thrive in rich organics that decompose, indicating abundant fungal life.
Over-Decaying Matter
Over-fertilization with compost or manure can lead to overpopulation, disrupting the ecosystem.
Damp or Over-Watered Lawn
Inadequate drainage and excessive water collection can attract mushrooms. Heavy watering can also trigger mushroom growth.
Increased Humidity and Temperatures
Higher humidity and temperature levels can trigger mushroom outbreaks in the hot summer months. Ideal conditions for fungal growth are damp, warm areas with abundant organic matter.
Mushroom Removal Before Mowing
Mushrooms reproduce by releasing spores, which can be removed naturally.
Too Much Shade
Mushrooms thrive in dark or semi-dark conditions, indicating shady conditions may be a potential breeding ground for mushrooms.
Airborne Spores
As they mature, spores disperse in the air, landing in the yard. These spores lay dormant until conditions are right, proliferating and repeating the cycle.
Common Misconceptions About Lawn Mushrooms
- All mushrooms are poisonous to the touch. This is not true. Other than rare skin allergies, toxic mushrooms are only harmful if ingested.
- You can control mushrooms by spraying the soil with lime. This is not true. Applying it can increase soil pH, making it more alkaline. However, mushrooms are indifferent to soil pH and can grow as readily in alkaline soil as neutral or acidic ones.
- Fungicides don’t eliminate mushrooms themselves, just the fungal diseases that exist on the leaves and stems.

How to Get Rid of Mushrooms on Your Lawn
There are many methods to help minimize mushroom growth on your lawn.
Nitrogen Fertilizer
Apply nitrogen fertilizer to your lawn. Nitrogen speeds up their growth and shortens their lifespan, so they’ll disappear quicker.
Don’t Over-Water
To minimize fungal growth, ensure proper soil drainage, reduce thatch, and aerate the lawn.
More Sunlight
Soak the area in sunlight when possible and remove decomposing plant material to cut off the mushrooms’ food source.
![Dethatch and Aerate](https://gogreenlawnservices.com/wp-content/uploads/2024/06/Dethatch-and-Aerate-1024x493.jpg)
Dethatch and Aerate
Scarify or dethatch your lawn to reduce thatch. Aerate your lawn to loosen soil compaction and improve water and air movement into the ground.
Clean Up
Pick up leaves, tree trunks, twigs, and animal waste to reduce the decaying matter that mushrooms thrive on.
Mow or Rake
Collect grass clippings when you mow or rake them afterward.
Dig Them Up
Dig the mushroom clumps out using a garden spade or shovel.
