Why do mushrooms or fungus develop?

  • Mushrooms are the fruiting bodies of fungi living in the soil and thatch of the yard or landscape.
  • Plant or organic material (roots, stems, leaves, grass blades, thatch, old tree roots) are constantly trying to break down in the soil naturally.
  • Wet conditions speed up the decay of organic matter.
  • Fungi live on decaying organic matter in the soil.
  • As organic matter decays, nutrients (predominantly nitrogen) become available for the inoculation of fungus spores.
