Why Are Mushrooms Growing in My Plant?

The most common reason mushrooms appear in potted plants is due to the presence of excess moisture and organic matter in the soil. Mushrooms thrive in damp environments, and when the soil remains consistently moist, it creates an ideal habitat for their growth. Organic matter such as decaying leaves, wood chips, or compost can also provide nourishment for mushroom spores, leading to their emergence.

How to Avoid Mushrooms Growing

To prevent mushrooms from sprouting in your plant, follow these tips:

  • Allow the soil to dry out slightly between waterings. Mushrooms thrive in consistently moist environments, so adjusting your watering routine can help deter their growth.

  • Improve drainage by using well-draining soil and ensuring that your plant's container has adequate drainage holes. Proper drainage helps prevent waterlogged soil, reducing the likelihood of mushroom growth.

  • Avoid overwatering your plant. Only water when the top inch of soil feels dry to the touch, and be mindful not to let excess water accumulate in the saucer or tray beneath the pot.

Organic Ways to Prevent Mushrooms

Preventing mushrooms is the best way to keep your plants healthy. However, using toxic substances to kill the fungus can cause your plants to die. Here are some organic methods to prevent mushrooms from taking over your plant:

  • Adjust the watering schedule to provide moisture only when necessary. This helps maintain a drier environment that is less favorable for mushroom growth.

  • Remove any decaying organic matter from the soil surface. This includes fallen leaves, dead plant material, or excessive mulch. By eliminating potential food sources, you discourage mushroom development.

  • Increase airflow around the plant by positioning it in a well-ventilated area. Good air circulation helps to reduce humidity levels, making the environment less suitable for mushrooms.

  • Consider using a layer of coarse sand or fine gravel as a top dressing for your plant's soil. This can discourage mushroom growth by creating a less hospitable surface for spores to take root.


While the presence of mushrooms in your plant may be unexpected, understanding the reasons behind their appearance can help you take proactive measures. By addressing excess moisture, improving drainage, and implementing organic prevention methods, you can discourage mushrooms from growing in your plant. Remember to adjust your watering habits, remove decaying organic matter, increase airflow, and consider using a top dressing. With these steps, you'll be well on your way to maintaining a healthy and mushroom-free plant environment.
