Things You'll Need:
- Garden rake
- Drainage system
- Aerator
- Fertilizer
-
Step 1
Break the mushrooms off using a garden rake. Pull them out as close to the ground as you can and throw them away immediately. Do not leave them lying on your lawn or put them in your compost bin or pile, as they may release spores and cause even more mushrooms to grow in your grass or garden.
-
Step 2
Reduce the amount of irrigation you are giving your lawn. A great deal of mushrooms are linked to excess standing water and a lack of drainage. Allow your yard to dry out, find ways to provide drainage if you live in an area that gets lots of rain, and cut back the irrigation. One inch of water each week is sufficient for your lawn to thrive.
-
Step 3
Rake your lawn regularly and remove grass clippings as soon as you mow. This provides better air movement and allows your lawn to dry more quickly, causing many types of mushrooms to die. It also provides less dead organic matter, which is what mushrooms use for food. Aerating the lawn helps in the same manner.
-
Step 4
Apply fertilizer to your lawn four or five times each year. Fertilizer helps hasten the breakdown of dead organic matter, such as dead leaves or tree roots under the ground. Perform a soil test, which you can buy at most garden centers, to determine the best fertilizer for your grass.
-
Step 5
Clean up your yard. If there is any organic matter in your yard that might be feeding the mushrooms, such as pet waste, rotten mulch or an old, dead tree or stump, remove these objects promptly to eliminate this food source and help control the mushrooms in your lawn.
