What Causes White Mushrooms To Grow in Your Yard?

Why Are White Mushrooms Growing in My Yard?

One thing to know about mushrooms is that they can stay dormant for years. Underground, the fungi stay hidden and feed off the organic matter from the soil.

It is only when the right conditions cause the mushrooms to begin to blossom overnight. If you find random mushrooms in your yard, then some of these factors could be responsible.

Organic Matter

Mushrooms survive on organic matter. While they live under our footsteps, they leech off the nutrients from the ground.

Dead leaves, mulch, animal waste, and other rotting matter feed the fungi. The bigger the presence, the bigger the mushroom patch.

Damp/Humid Areas

If you live in places with frequent rain and humidity, there’s a higher chance of getting mushrooms in your yard.

Mushrooms thrive in moist environments and areas with lots of rain. The fungi absorb the necessary moisture through the soil and fuel their spontaneous growth.

The humidity in the air acts as the appropriate temperature level for these mushrooms to emerge over time.


Mushrooms don’t grow well under direct sunlight. You can expect to find them around shaded areas in the corner of your eye.

In the shade, mushrooms can stay sheltered from heavy winds and brutal heat waves. Shady spots also compile more organic matter for the fungi to feed.
