Mushrooms in the Lawn?
Rings or clumps of mushrooms poking through lawns are common problems in western Washington. They result from fungal presence underground; the mushroom is the “fruit” of the fungus infestation. Get rid of mushrooms by raking them off the grass. Support the lawn with proper fertilization and watering when needed. No chemicals are registered for dealing with lawn mushrooms, thus no chemical treatments can be done. It’s also possible to drench the affected area with detergent and water, in early spring. Poke holes about 6 inches deep, about a foot apart, through the surface, and drench the area daily for a month. Use 1 to 2 quarts of water per square foot, with 1 to 2 tablespoons of liquid detergent per 3 gallons of water.
