What Do Mushrooms Need to Grow?

Fungi break down dead organic material, playing a pivotal role in the decay and return of such materials to the soil for future use by other plants. Some fungi produce mushrooms when the correct environmental conditions exist.

  1. Growing Site

    • Mushrooms must grow in some type of organic substance, such as ground wood chips, hay, compost or leaves. Mushrooms also grow on fallen logs and living trees. Different varieties of mushrooms prefer certain substrates to others.

    Climate

    • Mushrooms need mild weather with a stable temperature. Ideal temperatures vary depending on the mushroom species, but those between 55 and 70 degrees Fahrenheit produce the best results.

    Moisture

    • Mushrooms thrive in moist environments. In the wild, mushrooms are often seen sprouting approximately a week to 10 days after a rainy period.

    Light

    • Unlike most plants gardeners show interest in growing, mushrooms develop in dark, heavily shaded areas. Forests provide just such an environment, providing a haven for mushroom growth when other conditions remain favorable.
