Wild mushrooms can flourish in a yard, easily taking over spaces of moist, shaded dirt within days, particularly during wet seasons. This best way to get rid of mushrooms in your yard is to manually remove them before they reproduce from spores. It is necessary to completely remove the mushroom, not just the cap, to ensure the fungus spores are gone from the surrounding soil.
Remove the mushroom cap and stem from the ground with your hands. Dig under the area of the mushroom with the trowel at least six inches down into the soil. Dig up and discard this dirt, roots or mulch. This is important because the fungus can still spread if it touched these areas. Replace the missing soil with new potting soil.
Remove any thatch if necessary, because this can encourage wild mushroom growth. Getting rid of it with the rake will allow more sunlight and circulation to get in the dirt, which discourages mushroom growth.
Remove rotting wood, compost, grass clippings and other similar materials from the area where you are having problems controlling wild mushroom growth. These can all contribute to mushroom problems.
Consider switching up your yard's watering plan, especially if you live in a wet environment. If you decrease the amount of water your yard gets, it will help decrease mushroom growth.
