Mushrooms Growing from Houseplants: A Sign of Trouble or Something Beneficial?

“When the root is deep, there is no need to fear the wind.”


Discovering mushrooms growing from your houseplants can be a peculiar and unexpected sight. While they may look fascinating at first glance, their presence is often a sign of underlying issues with your plant's health or the growing environment. Mushrooms are fungi that thrive in moist, organic environments, making the soil of houseplants a suitable habitat for them to establish. However, their appearance indicates that the growing conditions are too humid or that organic matter is decomposing in the soil.

What Causes Mushrooms to Grow from Houseplants?

  1. Overwatering: Excessive watering is a common cause of mushroom growth. When the soil remains consistently moist, it creates an ideal environment for fungal spores to germinate.

  2. Poor Drainage: Insufficient drainage in the pot or planter can lead to waterlogged soil, providing favorable conditions for mushrooms to develop.

  3. Organic Matter Decomposition: The presence of decaying organic matter in the soil, such as dead leaves or plant debris, can attract fungi.

  4. High Humidity: High humidity levels in the surrounding environment promote the growth of mushrooms.

  5. Plant Stress: When houseplants are stressed due to factors like overwatering, poor lighting, or nutrient deficiency, they become more susceptible to fungal infections.


Are Mushrooms Harmful to Houseplants?

The presence of mushrooms is usually a symptom of an underlying problem rather than a direct cause of harm to your houseplant. However, some mushrooms can release spores that irritate the respiratory system of humans and pets. In rare cases, certain types of mushrooms can also produce toxins that may be harmful if ingested.

How to Manage Mushrooms Growing from Houseplants

  • Adjust Watering:

-Reduce the frequency of watering to once or twice a week, depending on the plant's needs.

-Water deeply each time to encourage deep root growth and prevent shallow roots from sitting in waterlogged soil.

-Allow the top inch of soil to dry out completely before watering again.

-Avoid misting or overhead watering, as this can increase humidity and create a favorable environment for mushrooms to thrive.

  • Improve Drainage:

-Choose pots or planters with adequate drainage holes.

-Add a layer of gravel or pebbles to the bottom of the pot to improve drainage.

-If the pot is sitting in a saucer, empty the saucer after watering to prevent water from collecting around the roots.

  • Remove Organic Matter:

-Gently remove any dead leaves or plant debris from the soil.

-This helps prevent the buildup of organic matter, which can trap moisture and create a favorable environment for mushrooms.

  • Reduce Humidity:

-If the surrounding environment is too humid, consider using a dehumidifier to lower the humidity levels.

-You can also move the plant to a less humid location, such as a sunnier spot in the room or a room with better air circulation.

  • Repot the Plant:

-If the mushroom issue persists, consider repotting the plant in fresh, well-draining soil.

-Gently remove the plant from the old pot, shake off the old soil, and inspect the roots for any signs of rot or disease.

-Prune away any damaged roots and repot the plant in a clean pot with fresh potting mix.

  • Use Fungicides:

-In severe cases, you may need to apply a fungicide to control the growth of mushrooms.

-Consult with a gardening expert to choose the appropriate fungicide for your plant and follow the instructions on the product label carefully.

-Apply the fungicide according to the label's instructions and be sure to wear protective clothing and gloves when handling the product.


Mushrooms growing from houseplants can be a sign of imbalances in the growing environment. By addressing the underlying causes, such as overwatering, poor drainage, and high humidity, you can resolve the issue and help your plant thrive. If the mushroom problem persists or you have concerns about potential health risks, it's best to consult with a plant care professional for guidance.
