Mushrooms are the fruit of a fungus that has entered your potting soil either before you purchased it (contaminated potting mix from the store) or through airborne spores. They are not plants and only the fruit is visible to us. Mushrooms are not harmful to plants and can even be beneficial. They aid in the exchange of nutrients and water from the soil to the plant. However, they can indicate that something is not right with your care routine. Mushrooms thrive in moist, humid, and nutrient-rich environments with low light exposure and poor drainage. If left untreated, the fungus can take over, rot the roots, and cause your plant to die.

What You'll Learn
Mushrooms can indicate poor plant care
While mushrooms themselves are not directly harmful to plants, their presence can indicate that something is amiss with your care routine. Mushrooms thrive in moist, humid, and nutrient-rich environments with poor drainage and low light exposure. If left untreated, the fungi can take over, causing root rot and eventually killing the plant. Therefore, it is important to address the underlying issues that led to their growth and remove the mushrooms to maintain optimal plant health.
Mushrooms are the fruit of a fungus that has entered your potting soil either through contaminated store-bought soil or airborne spores. They reproduce by expelling spores, which become new mushrooms. Mushrooms need water to grow and expand their cells, so they are often a sign that your plants are being overwatered. While organic soil is beneficial for plants, too much moisture combined with organic matter can encourage mushroom growth.
To prevent mushrooms from taking over your garden, create an unfavourable environment for them. Ensure that the soil is not extremely damp or wet and improve airflow and light exposure. Consider repotting with fresh soil and adjust your watering schedule to allow the soil to dry out between waterings. You can also try methods of watering that keep the top layer of soil dry, such as watering the tray of the plant container instead of the soil directly.
While mushrooms are not harmful to plants, they can be toxic if ingested by humans or pets. Additionally, their presence may indicate that your plant is already dying or decaying, as fungi typically go for organic material that is beginning to decay. For example, if shelf fungus forms on a tree, it is likely that the tree is already in poor health. Therefore, it is important to address the underlying issues that led to mushroom growth and remove the mushrooms to ensure the health of your plants and loved ones.

Mushrooms can be harmful to humans and pets
Mushrooms are a complicated food group. While many mushrooms are edible and safe, they are fungi, not plants, and many contain toxins that can result in mild to severe illness and even death in both humans and pets. The toxins can be broken down into four general categories: gastrointestinal (GI) toxins, neurotoxic toxins, cytotoxic toxins, and unknown toxins. The severity of mushroom-induced illness depends on the type and number of mushrooms ingested.
In pets, mild gastrointestinal upset, including vomiting and/or diarrhea, may resolve at home. In more severe cases, pets may become extremely sick and require hospitalization, and some pets die despite therapy. The onset of illness can be rapid, with signs occurring within 30 minutes to 6 hours. Signs of neurotoxicity include weakness, lack of coordination, tremors, hallucinations, vocalizations, disorientation, agitation, altered mentation, drooling, vomiting, and seizures. Body temperature may rise, and these toxins can also affect the kidneys and liver.
In humans, mushroom poisoning can be fatal. The symptoms of mushroom poisoning depend on the species of mushroom. Certain mushroom species contain different toxins, which affect humans and animals differently. Visual identification of poisonous mushrooms can be difficult, even for experts, and the appearance of mushrooms can be distorted by mastication, gastric secretions, or orally administered treatments. In cases of human poisoning, PCR assays have been used to identify ingested mushrooms when visual identification is inconclusive.
It is important to note that mushrooms sold in large and chain grocery stores may be generally safe for humans and pets. However, it is generally safer to avoid feeding dishes with mushrooms to pets, as they do not need mushrooms in their diet.

Mushrooms can indicate root rot
Armillaria root rot is particularly harmful to smaller trees and plants, which can be debilitated and killed quickly. However, even large trees can eventually succumb as the fungus spreads and kills off more roots, leaving the tree susceptible to windthrow or windsnap. Infected plants may not show symptoms for months or even years, but once the disease takes hold, it can result in the sudden death of part or all of the plant.
The presence of certain types of mushrooms can be a tell-tale sign of root rot. Short-lived yellow to brown mushrooms that grow in clusters near trees or shrubs are likely indicative of Armillaria root rot. However, it's important to note that the absence of mushrooms does not rule out the possibility of infection. To confirm the presence of root rot, one should look for white mycelial growth under the bark of the affected plant.
Preventing and managing root rot involves keeping landscapes free of infected trees, shrubs, and plants to slow the spread of the fungus. Maintaining optimal conditions for plant health is also crucial, as stressed trees are more vulnerable to infection. When removing infected plants, it is essential to get rid of as much of the root mass as possible and replace the surrounding soil before replanting.

Mushrooms can indicate poor drainage
Mushrooms are fungi, not plants. They grow in moist, humid environments with low light and poor ventilation. Mushrooms can be a symptom of poor drainage, which can lead to standing water or consistently soggy soil—the perfect breeding ground for mushrooms.
Mushrooms are attracted to potting soil, indicating that the soil may be too moist for plants. Proper drainage in containers is essential. Mushrooms grow as fast as water can be absorbed into their cells, and they need water to keep from drying out. However, too much water can kill a mushroom, as it also needs oxygen.
To prevent mushroom growth, keep the soil drier. Allow the surface of the soil to dry out between waterings and ensure proper drainage. Try methods that keep the top inch or two of the soil dry, such as watering the tray of the plant container and letting the potting soil absorb the water. You can also use a watering bulb that is stuck into the soil.
While mushrooms are not dangerous or bad for plants, they can be a safety concern in high-traffic areas or for children and pets who may ingest them. Some mushrooms are poisonous, and even non-toxic mushrooms can indicate the presence of mould and mildew, which can cause allergic reactions or respiratory issues. Therefore, it is crucial to remove mushrooms promptly and address underlying moisture problems to prevent health risks and further fungal growth.

Mushrooms can be beneficial to plants
While mushrooms growing in your garden or houseplants can be unsettling, they are typically not harmful to plants and can even be beneficial. Mushrooms are the fruit of a fungus that has entered your potting soil either before you purchased it or through airborne spores. They thrive in moist, humid, and nutrient-rich environments, so their presence often indicates overwatering or poor drainage. However, rather than being detrimental, mushrooms can improve the quality of your potting soil.
Firstly, mushrooms are important decomposers, breaking down organic materials and returning nutrients to the soil, which can then be used by plants. This compost increases the nutrient content of the soil, benefiting the plants growing in it. Additionally, mushrooms aid in the exchange of nutrients and water from the soil to the plant. They trade phosphates, an organic compound vital to plants, for sugars, fostering a symbiotic relationship.
Mushrooms also assist in communication between the root systems of plants, helping them defend against diseases and pests. Their presence can indicate that your plants are part of a thriving ecosystem. Furthermore, some view mushrooms growing in their gardens as a sign of good luck.
However, it is important to note that mushrooms can be toxic if ingested by humans or pets, and their presence may sometimes indicate underlying issues with plant health. For example, shelf fungi growing on a tree may signify that the tree is already decaying. Therefore, while mushrooms can be beneficial to plants, it is advisable to maintain optimal plant health by adjusting watering routines, improving airflow, and providing adequate light exposure to prevent excessive moisture, which can lead to root problems.
