Due to the recent rain and warm weather, we are receiving more inquiries regarding mushrooms in lawns. It's a good thing you have them, despite their appearance. Mushrooms indicate healthy soil in your yard.

Mushrooms are the reproductive organs of fungi. Mushrooms are fungi, but not like mildew or other fungi. Mold, yeast, and rust are among the 144,000 recognized species. Some mushrooms are edible and safe to eat, while others, including those that grow in your yard, are toxic if eaten or touched.

Mushrooms, as scary as they sound, are a healthy lawn sign. That being said, let's examine the benefits of mushrooms in lawns.

How Do Mushrooms Form?

Mushrooms frequently appear after heavy rains and when the weather is hot and humid. They grow above ground, on soil or food sources, but don't last long. They'll spread their spores and then vanish as the sun shines and the soil dries. They vanish as quickly as they appear.

What Causes Mushrooms to Grow on Lawns?

Mushrooms only grow on lawns with rotting wood. Get rid of the decaying woody material to get rid of the mushrooms.

To reduce lawn mushrooms, add more green material (grass clippings and vegetable leaves vs. tree leaves) to the soil. Mulching grass clippings into the soil works well. Bacteria-rich soils have more leafy than woody food. Soils with fungi are rich in lignin-based foods like tree leaves and rotting wood. Mushrooms are less common in soils with a neutral mix of bacteria and fungi.

Mushrooms often appear after periods of excessive moisture, which can stimulate beneficial microbial activity. No, mushrooms aren't bad for your lawn; they're usually a good sign! They are a clear sign of healthy soil, which promotes healthy lawns and trees. The mushrooms usually vanish almost as quickly as they appear.

If you have mushrooms in your lawn, they are decomposing woody organic matter in the soil.

Why Mushrooms On Your Lawn Are A Good Thing

Soil microbial activity is beneficial to mushrooms in your lawn. Many soil reactions and functions rely on microbial activity.

Composting of organic materials, including

  • Formation of humus
  • Cycling nutrients
  • Aggregate formation
  • Stabilization

Decomposing organic matter requires them to function properly.

How to Get Rid of Mushrooms in Your Yard

If mushrooms keep appearing in your lawn or you want to get rid of them, treat them like a pest, starting with integrated management. Dethatching and adjusting water schedules can help prevent big outbreaks. You can also remove the yard mushrooms.

Reduce the water and shade on your lawn.

To make your lawn less attractive to fungi, first improve drainage with the help of a lawn aerator. Trim and/or thin nearby tree branches so that more light can reach the lawn, thus making the environment less agreeable for mushroom growth.

Clear out some organic material.

Fungi feed on decomposing organic matter, from dead tree roots to grass clippings. Periodically dethatch your lawn in the areas where you see mushrooms. If the fungi are feeding on organic material submerged in the soil, you'll need to dig that out too. Once the fungi have devoured all of that submerged organic material, the mushrooms should disappear.

Remove each mushroom at its base.

You can pull mushrooms individually by hand, cut each with a knife, or simply mow over the entire area with the lawnmower. If pervasive, be sure to remove yard mushrooms as soon as you see them sprout. Don't dispose of them in your compost; instead, throw them into a plastic bag and tie it tightly before discarding it in the trash. A DIY remedy: 5 tablespoons of vinegar per gallon of water mixed and poured into a sprayer.

FAQ About Getting Rid of Mushrooms

Are mushrooms a sign of a healthy lawn?

Yes! If you see fairy rings and poor lawn health, mushrooms could be a sign of overwatering or watering too much at night. Mushrooms are an excellent sign of healthy soil since they reproduce fungi.

How do I stop mushrooms from growing on my lawn?

Overwatering grass to prevent mushroom growth is avoided. You can also water early in the day to avoid a soggy lawn in the evening. If mushrooms are dense, consider manual removal. If possible, avoid using fungicides.

Is it necessary to remove mushrooms from my lawn?

Although few mushrooms are poisonous, pets and children should not be exposed. White mushrooms may appeal to kids due to their familiarity. Remember that toadstools only appear under certain conditions. Don't panic and spray your lawn with fungicides. They can harm beneficial fungi.

How do I get rid of mushrooms in my lawn without killing the grass?

Hand-picking the mushrooms, which merely spread fungal spores, is the best approach to avoid lawn damage. Healthy fungi, which are underground essential parts of soil health, are crucial to a healthy lawn.

Fairy rings and fungi-infested areas can kill grass, although nitrogen fertilizer can hide symptoms and deep soil improves grass health.

Is lawn mushroom edible?

Some lawn mushrooms are edible, but check a foraging field guide or your local cooperative extension office before eating any yard fungus. If the mushrooms are harmful, they can develop symptoms days later. These symptoms can range from moderate stomach irritation to organ damage.


Instead of fearing lawn mushrooms, befriend them. If you don't like the way they look on your lush green lawn, rake or pick them up. But don't use chemicals to solve the issue.

Adjust lawn watering as needed, or just relax and wait for the weather to change to get rid of the mushrooms. Accept these capped fungi "seeds" as beneficial to your lawn's health.
