How to Get Rid of Mushrooms in Your Yard

Mushrooms might be delicious on the grill, but those aren’t the ones growing on your lawn. (Seriously, please don’t eat mushrooms from your lawn.) If you have toadstools sprouting in your yard or at the base of your trees, you’re probably eager to get rid of them. 

Here’s how to rid your space of these likely poisonous fungi and how to stop them from returning once and for all.

How to Get Rid of Mushrooms

If you have a colony growing on a stump or brush piles, it’s important to get rid of it ASAP, as mushrooms can be toxic to people and pets. Whether you are looking for natural ways to get rid of mushrooms or prefer something stronger, there’s a remedy to match. 

Here are some ways to say “see ya” to those pesky shrooms.

1. Dig Them Out

Dig out any visible mushrooms in the ground. Wear gloves to bag up the debris. You might have to remove some soil to get rid of the mushrooms. Be careful to contain the area as much as you can—you don’t want to spread the spores.

2. Dry Them Out

Mushrooms thrive in damp, shaded areas, so you can kill mushrooms by drying them out. Keep in mind that this method can kill grass as well since you can’t water as often or mow to encourage strong roots.

Here’s how: 

• Prune the branches on the tree or bush that’s giving them shade.

• Improve the drainage in that area and stop watering that part of your yard. 

• Clean up the damp leaves and debris. 

• Don’t mow the area until the mushrooms are gone. Mowing can spread the spores far and wide.

3. Sprinkle on Baking Soda

Baking soda can be a treatment for controlling mushrooms. Sprinkle it right on the ground or mix with water and spray it in the area. Baking soda helps raise the pH level of the soil, something mushrooms don’t like. But don’t expect immediate results, and you might need to treat the area with baking soda a few times for it to work.

You’ll also want to consider that baking soda can harm and even kill grass before going with this mushroom-eradicating method.

4. Level Up With Lime

Hydrated lime will also raise the pH level of the ground and help kill mushrooms. Pick up a bag at hardware stores and sprinkle or spray it on the area as directed on the package. Make sure to protect yourself with gloves and goggles when you work, and keep kids and pets out of the treated area for a few days.

5. Step It Up With Vinegar

If baking soda or lime didn’t do the trick, take things up a notch with a spray of vinegar. But don’t just use whatever you have in the kitchen; ask for weed-killing vinegar at your local hardware store.

Protect yourself with long pants and sleeves and eye protection when using vinegar or any weed killer. Also, know that this can kill your grass and any plants in the area.

6. Use a Fungicide

You can find a mushroom fungicide that you spray on with a hose, or powders you sprinkle on the area. Fungicides are meant to kill the mushroom at the root rather than the ones that have already popped their caps out of the ground.

Make sure to follow the instructions on the label and wear protective gloves. Keep children and pets away from the treated area. Contact a lawn treatment company in your area for help if you need it.

Why Mushrooms Grow in Lawns

All types of yard mushrooms love damp, shaded spots with decaying organic matter to feed off. An ideal spot for them is that soggy pile of brush and leaves back by the shed. 

Here are the most common reasons mushrooms grow in yards:

• Excess shade in your yard: Mushrooms thrive in dark, moist areas.

• Compacted soil: Compacted soil doesn’t drain well, which creates the perfect conditions for moisture-loving mushrooms.

• Pet waste: If you leave pet waste in your yard too long, mushrooms can grow. 

• Tree stumps: If you have spots in your yard where a tree once stood (whether there’s a stump or not), the dead roots may encourage mushroom growth.

How to Stop Mushrooms From Growing

Now that you know how to get rid of mushroom clusters in your yard, let’s focus on prevention. The following tips will help prevent wild mushrooms from coming back. 

• Rake leaves: Bag leaves up after raking and compost them rather than leaving a pile in your yard. 

• Scoop pet waste: Mushrooms thrive on pet waste, so get out there with the pooper scooper regularly.

• Get rid of tree stumps: Hire a local tree removal company to remove old tree stumps to discourage mushroom growth.

• Fix clogged gutters: Gutter issues can cause flooding in your yard, and mushrooms thrive in moist soil. 

• Aerate your lawn: When you create proper drainage, water can’t sit on top of your grass and encourage mushroom growth. If you need help, call a local lawn aeration company. 

• Prune large trees and bushes: Mushrooms love dark places, so trim your trees and let the sunlight into your yard. 

If you need help maintaining your lawn, hire a local lawn care service to discourage mushroom growth by trimming grass and raking leaves. You can also ask them to remove mushrooms if they pop up.

Common Types of Mushrooms That Grow in Lawns

The fungi kingdom produces some of the planet's most widespread organisms, so it’s no surprise to see a few shrooms in your yard. Here are the mushroom species you’re most likely to encounter on your property.

Meadow Mushroom (Agaricus campestris)

These white fungi have a quintessential mushroom shape: a bell-like cap with a round stem. They pop up in mid-summer, usually following an area’s rainy season, and last through early fall. While meadow mushrooms are edible, be careful before digging in because many toxic mushrooms look very similar. 

Mower’s Mushroom (Panaeolus foenisecii)

You’ve likely come across these small brown mushrooms before, as they’re one of the most common varieties in North America, particularly in the damp Pacific Northwest. They can be toxic—but not deadly—if ingested in large doses, so most parents and pet owners will want to remove them.

Puffball (Lycoperdon perlatum)

Puffball mushrooms come in all shapes and sizes. Some are less than a half-inch in diameter and look like golf balls hiding in your yard, while others can reach 25 inches in diameter. Aside from their globular form, puffballs are easy to spot because they commonly grow in clusters.

Fairy Ring Mushrooms (Marasmius oreades)

If you see tan umbrella-shaped mushrooms growing in a circle, there’s a good chance they’re fairy rings. Expect to see them spring up in grassy areas from May to September. Keep in mind that fairy ring mushrooms become larger every year if you let them stick around. Like meadow mushrooms, this species has many non-edible lookalikes, so don’t judge them as safe based only on the circle pattern.

Common Stinkhorn (Phallus impudicus)

It would be nice if “stinkhorn” was a misnomer, but unfortunately, these mushrooms emit an odor widely described as smelling like decaying flesh. The long, cylindrical fungi come in various colors, including white, tan, and orange.

Lawyer’s Wig (Coprinus comatus)

This distinctive mushroom is common throughout North America and Europe. Their ruffled caps lead to other popular names, like “shaggy mane” and “shaggy ink cap” mushrooms.

Milky Conecap (Conocybe apala)

There are a few Conocybe species likely to appear in your yard, namely the milky conecap and the common conecap. The former are usually white in color, while the latter are brown. These mushrooms have a hood-shaped cap and long, thin stems.
