If you want to know how to get rid of mushrooms in your yard, you've come to the right place. Of course, a couple of mushrooms may not be anything to worry about, but if your lawn is looking unsightly because there are too many, there are easy steps you can take to remove them.
Think of the process as part of your autumn lawn care, and it won't even take up much of your time.
What causes mushrooms to grow in your yard?
But first, why do mushrooms grow in your yard in the first place? Emilly Barbosa Fernandes, Small Space Gardener and consultant at House Grail (opens in new tab), explains that 'There are two necessary and sufficient conditions for mushrooms to grow in your yard: the presence of fungal threads and healthy soil. Fungal threads (fungal mycelia) are located 3-4 inches below the soil surface and can exist there for decades. In fall, there is enough rain for fungal mycelia to start fruiting. As a result, you see the mushrooms popping up in your yard.'
The big question is whether mushrooms cause a problem in the first place. Ethan Howell, Co-Owner of Florida Environmental (opens in new tab), points out that 'on lawns with enough organic materials, this organic debris feeds your grass.' Ethan's recommendation is that 'if you simply have a few mushrooms in your yard, you don't need to do anything about them. They don't harm your yard.'
How to get rid of mushrooms in your yard
If you do feel that there is a problem with too many mushrooms, Emily says that 'you can just pick them off or remove them with a rake.' She cautions against 'using any chemical or synthetic substance to remove the mushrooms. The chemicals may cause a reaction with the humus layers, and kill your lawn and everything else in your soil.'
One thing to know about mushrooms is that they like compacted soil, so, according to Emily, 'to minimize mushroom growth, you should trim your trees and bushes, remove yard tents or any other sources of shade. To prevent compacted soil, you should avoid regularly aerate the lawn.' Learning how to aerate a lawn is well worth doing for many reasons, not just mushroom removal.
Ethan also explains that a major source of mushroom growth in gardens is tree stumps, 'because fungi feed on decomposing organic substances. Removing tree stumps or decaying logs from your yard reduces the amount of decomposing matter available to mushrooms.' With a few tried-and-tested method, it can be easier to learn how to remove a tree stump than you might think too.
Another mushroom growth trigger people sometimes forget about is pet waste. Ethan points out that it 'contains nutrients that allow mushrooms to flourish. On occasion, old dog droppings sprout mushrooms. Removing this trash can help prevent mushroom growth.'
Removing mushrooms from your backyard isn't difficult, and may not even be necessary unless you have a pet that might eat them. If you do have a bit of a problem, just picking or raking them off is the best and safest solution.
