Why do I have mushrooms growing in my yard?

The first step in getting rid of mushrooms is understanding why they’re there in the first place. Mushrooms are the result of a fungus that exists in your lawn’s soil. The fungus thrives in moist, low-light conditions where there are plenty of decaying organic materials. For this reason, the presence of mushrooms in your yard could be a result of:

  • Excessive rain or watering
  • Unaddressed dead plants, grass clippings, or thatch buildup
  • An overly shaded yard
  • Abandoned tree stumps or woodpiles

While mushrooms aren’t usually harmful to your lawn or garden, some varieties are toxic to humans and animals. If you have curious children or pets, it’s a good idea to rid your yard of those pesky mushrooms.

How to get rid of mushrooms in yards

Mushrooms are invasive because they release spores that act as seeds. If these spores remain in any area of your lawn, more mushrooms will eventually pop up. To get rid of mushrooms, there are a few phases of the process you’ll have to carefully move through.

Handpick any visible mushrooms

Step 1: First, you’ll need to manually remove all of the mushrooms in your yard. This should be done by hand and not with the use of a lawn mower or rake. Handpicking the mushrooms will ensure the spores released during removal are kept to a minimum.

Step 2: Be sure to have a plastic bag with you as you move around your yard picking mushrooms. Don’t simply throw them into a pile, as this will encourage the release of spores.

Step 3: Once you’ve picked all the mushrooms, tightly close the bag and either burn it or throw it in the trash.

Step 4: Don’t use mushrooms in your compost bin — this is a sure way to spread spores and encourage mushroom growth.

Fertilizing lawn

Treat your lawn with fertilizer

One surefire way of killing mushrooms is to cut off their food source. This is a particularly useful method if you’ve got a significant mushroom invasion on your hands. A nitrogen-rich fertilizer will go a long way in eradicating a mushroom problem once and for all. This is because nitrogen speeds up the decaying process of the organic matter in your soil, which is what mushrooms feed on, and gets rid of it.

How do I get rid of mushrooms in my yard naturally?

If you’re not comfortable using fertilizer on your lawn, some people have success using vinegar. It’s best to use a concentrated, industrial-strength vinegar that has a high pH level. Vinegar is highly acidic, so it has natural anti-fungal properties. To use vinegar instead of fertilizer for mushroom eradication, you’ll have to be a bit more diligent with the process.

Step 1: Dilute the vinegar and spray it directly onto the mushrooms. This will kill the active mushrooms and prevent them from releasing spores.

Step 2: Examine your lawn daily for any new mushroom growth and repeat the process.

How do I stop mushrooms growing on my lawn?

One important task in the mushroom-removal process is ensuring that they don’t continue to grow back. The best way to stop mushrooms from growing in your grass is to make your lawn as undesirable as possible for fungal growth. We talked about how mushrooms thrive in environments that are moist, have limited light, and contain a lot of decaying organic matter. It makes sense, then, to ensure your lawn doesn’t have these qualities.

Trimming trees

Trim trees and bushes

You probably notice those pesky mushroom caps in areas that are shaded. To let more light onto the soil in those spots and discourage mushroom growth, trim back tree branches, bushes, and large plantsto create less shade.

Remove organic material that will decay

You’ll have to be diligent about cleaning up your yard for a while after killing mushrooms. In order to cut off their food supply and discourage growth, make sure to quickly remove:

  • Grass clippings
  • Fallen branches
  • Pulled weeds
  • Thatch
  • Dog poop
  • Leaves
  • Pine needles and pine cones
  • Dead pieces of wood

Adjust your watering schedule

Since mushrooms love moist soil, it’s possible that you’re watering too often.

Step 1: If you’re watering your grass with a garden hose or sprinklers, reduce your watering sessions for a while and only water when the soil gets dry.

Step 2: If it’s simply a heavy rain season, there’s not much you’ll be able to do to limit watering. However, trimming branches to let more light in will help dry out the soil faster.

Mushrooms aren’t always harmful, but they are invasive and can make your lawn look less aesthetically pleasing. If you’re tired of seeing those pesky little caps in your grass, there’s plenty you can do to eradicate mushrooms for good. Treating your lawn, whether with fertilizer or a natural solution, and creating an environment where mushrooms won’t thrive will go a long way in keeping your lawn green, pristine, and mushroom-free.
