How to Kill Fungus & Mushrooms

There are many varieties of mushrooms and fungi in gardens and lawns.

Mushrooms and fungi reproduce by sending spores into the air. Simply cutting mushrooms is not enough. First, the act of cutting them can release additional spores and you will have more mushrooms in the same location in a matter of days. Also, mushrooms have large root systems and will simply sprout again after cutting. While mushrooms and other fungi can be unattractive in your lawn or garden, in smaller quantities they are not harmful to your yard as long as they do not take over the area completely. Many times you can correct the problem without resorting to harsh chemicals.

Things You'll Need

• Rake
• Garden tools
• Pruning shears
• Garbage bags

Instructions

1. Check the drainage situation in your lawn. Mushrooms and fungi thrive in damp, shaded areas. If your lawn develops puddles or marshy areas, these are likely the spots that mushrooms and fungi will inhabit. Correct any drainage issues to create a less hospitable environment.

2. Clean up lawn clippings, old mulch and other yard waste. Mushrooms and fungi feed on and break down decaying organic matter. This can be a good thing for your lawn, but if the mushrooms are taking over you need to take away their food source. Use a rake and other garden tools to clean up any yard waste and consider using a mulching lawn mower if you do not want to bag up your lawn clippings when you mow.

3. Thin out branches, leaves or plants in overly shady areas of your yard. Mushrooms and fungi are fond of dark areas, and if you expose these areas to more sunlight the area will dry out and the mushrooms will as well. Use pruning shears on heavier branches and bag up the yard waste in garbage bags.

4. Treat your lawn with a commercial fungicide if you still cannot rid your lawn of the mushrooms and fungi. Follow all package instructions completely. You may need to apply more than one treatment, depending on the amount and type of mushrooms and fungi in your yard.
