Lawn mushrooms, including bright red toadstools, jelly fungus, and puffballs, indicate healthy soil. They help lawns grow by breaking down organic matter, making soil nutrients more accessible to plant roots.
Causes of Mushrooms in Lawns:
Shady, Moist Areas: Mushrooms thrive in shady spots with overhanging trees.
Heavy Rainfall: Excessive moisture from rainfall or overwatering promotes mushroom growth.
Warm Temperatures: Warm, humid conditions (65-75°F) are ideal for mushrooms.
Nutrient-Rich Soil: Soils rich in organic matter and decaying wood feed mushrooms.
New Soil/Compost: Mushroom spores can be introduced through new soil or compost.
Benefits of Mushrooms in Lawns:
Waste Removal: Mushrooms decompose plant material, insects, and debris, recycling nutrients.
Improving Soil Structure: Mushroom filaments bind soil, enhancing structure, drainage, and moisture retention.
Boosting Plant Health: Mushrooms improve nutrient availability, promoting better grass growth and disease resistance.
Supporting Biodiversity: Mushrooms support beneficial soil microbes and provide food for wildlife.
Should You Remove Lawn Mushrooms?
Removing mushrooms isn’t always necessary, as they benefit plants and often disappear on their own. To discourage mushroom growth:
Prune branches to increase sunlight and improve drainage.
Aerate soil, reduce fertilizer, dethatch grass, and remove lawn clippings/woody debris.
Handpick poisonous mushrooms if children or pets are present.
Mowing or using fungicides is not recommended.
