Can I stop mushrooms coming up in the garden?
Mushrooms and other larger fungi may appear in the garden anywhere there is organic matter for the fungi to feed on They can establish in the garden from spores spread by wind and water or can be brought into the garden living in organic landscape mulches, such as wood mulches.
When the fruiting body of the fungus appears it can be removed and disposed of before it releases its spores. Always wear gloves when removing fungi by hand. The earth or organic matter that the fungal fruiting body emerged from can also be disposed of in an effort to remove the hidden thread-like mycelium.
