Good lawn-care practices like dethatching and changes to timing or amount of water can prevent large outbreaks. If mushrooms continue to crop up in your lawn or you want to be rid of them, tackle the issue like you would address a pest problem, beginning with integrated management. Mushrooms can signal overwatering of the lawn, which means wasting water, too.Continued fungi growth above the soil can damage localized areas of grass.A few lawn mushroom species are toxic, and kids or dogs might eat them, leading to (sometimes severe) stomach upset.The puffs and mushrooms can look unsightly in an otherwise pristine lawn.Their presence might signal some problem as well: The patterns might be followed by half-circles of white mushrooms or puffy balls the circles often are called “fairy rings.” Potential Drawbacks of Lawn MushroomsĪlthough mostly harmless, there are a few drawbacks to having mushrooms in the lawn. Appearance of mushrooms can signal excess moisture (from overwatering, for example), Cusick adds.īrowning grass in dark circles or bands might appear before mushrooms, and is a natural part of the soil process. Since the mushrooms crop up from fungi, the good news is that fungi are working beneath the surface. “Mushrooms are actually a good sign that your lawn’s soil is healthy,” says David Cusick, executive editor of House Method. The fungi return the favor by helping turn the clippings and leaves into soil nutrients. So, in the lawn ecosystem, leaves or grass clippings fall on the yard, and offer carbon and other nutrients to fungi.

Soils already contain plenty of fungi, and the fungi help cause organic matter to decompose.
