What You'll Learn

Mushrooms can be a sign of healthy soil
Mushrooms in your garden are not necessarily a cause for concern. They are a sign of healthy soil and can be beneficial to your garden. 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 produce spores instead of seeds, and the origin of the mushroom spores is the gill area underneath the mushroom's cap. Mushrooms do not grow just about anywhere; they need the right conditions. Some mushrooms prefer cool, moist conditions, while others thrive in warm, stagnant, and moist environments.
Mushrooms are not plants; they are fungi. The only visible part of the mushroom is its fruit—the rest of the mushroom is microscopic. A mushroom has the same number of cells when it is microscopic and after it has become a visible mushroom. Unlike animals, which create more cells to grow bigger, the mushroom expands its cells with water. This is why mushrooms grow as fast as water can be absorbed into the cells.
Mushrooms are decomposers that break down dead and decaying organic matter such as stumps, old roots, or leaves. They help compost the soil, turning organic wastes into usable compost for your plants. They increase potting soil quality and are beneficial to plants. They can also help process toxins, assist vascular plants in taking up soil water and nutrients, and aid in the decomposition process that converts decaying material nutrients into forms that your garden plants can use and thrive upon.
However, it is important to note that not all mushrooms are beneficial. Some can be toxic or poisonous, and it is dangerous to consume them. It is also challenging to identify mushrooms, and even those that are purportedly edible can make some people very ill. Therefore, it is best to avoid eating wild mushrooms unless you are absolutely certain of their edibility.

They can help process toxins and aid decomposition
Mushrooms are the fruit of a fungus that has entered your potting soil. They produce spores instead of seeds, and the origin of the mushroom spores is the gill area underneath the mushroom's cap. Mushrooms do not take nutrients away from the potting soil. In fact, they increase potting soil quality and are beneficial to plants. They help compost the soil, turning organic wastes into usable compost for your plants. They help break down nutrients to feed your plants.
Mushrooms also help in processing toxins and aiding decomposition. They feed on decaying matter, such as rabbit poop, mulch, or compost. They are a good sign for your garden beds and help keep the soil healthy. They quickly decompose and turn back into soil nutrients. As they are growing, they are helping to process toxins, assisting vascular plants in taking up soil water and nutrients. They aid in the decomposition process that converts decaying material nutrients into forms that your garden plants can use and thrive upon.
If you are unwilling to wait for mushrooms to go away on their own, you can remove them by hand or with a lawnmower. However, removing the mushrooms themselves does nothing to affect the fungi in the soil, and it will only reduce the number of spores released into the environment.

They can indicate a problem, like a diseased tree
While mushrooms in your garden are generally harmless and can even be beneficial, they can sometimes indicate a problem. For example, if you notice shelf fungus forming on a tree, it is likely that the tree is diseased and needs to be checked by an arborist. Shelf fungi feed on the wood of trees, and by the time you see the fruiting bodies, the fungus may have already consumed a significant portion of the tree.
Mushrooms are the fruiting bodies of fungi, and their presence can indicate the presence of organic matter in your garden. This could include decaying material such as leaves, stumps, old roots, or compost. While mushrooms themselves do not pose a direct threat to your garden, the underlying cause of their growth, such as excessive organic matter or a diseased tree, may need to be addressed.
It is important to note that not all mushrooms are harmless. Some mushrooms can be toxic or poisonous, and it is difficult for untrained individuals to identify edible mushrooms accurately. Therefore, it is generally advised not to consume mushrooms from your garden unless you are absolutely certain of their edibility.
Additionally, while mushrooms can be a sign of healthy soil, an overabundance of mushrooms could indicate overly fertile soil or overwatering. Mushrooms thrive in moist and humid conditions, so if you notice an excessive number of mushrooms, it may be a sign that your garden is not draining properly or that you are overwatering your plants.
In summary, while mushrooms in your garden typically do not cause harm, their presence can sometimes indicate an underlying problem, such as a diseased tree or excessive organic matter. It is important to identify the cause of mushroom growth and take appropriate action to maintain the health of your garden.

They can be poisonous to humans and pets
Mushrooms can be a concern for gardeners, especially when it comes to the safety of humans and pets. While most mushrooms that appear in your garden are likely to be non-toxic, it is important to remember that some can be poisonous and pose a risk to people and animals. The risk of poisoning is a serious issue and it is important to be able to identify any toxic varieties that may spring up in your garden. Some mushrooms contain toxins that can cause severe illness or even death if consumed, and this risk extends to pets as well. Cats and dogs, for example, can be curious and may ingest mushrooms while exploring the garden. It is crucial to keep an eye on your pets when they are outdoors and monitor their behavior and health after they have been in the garden.
Symptom-wise, poisoning can cause a range of issues, including gastrointestinal problems, hallucinations, and in some cases, organ failure and death. It is important to seek immediate medical attention if you suspect that you or your pet has ingested a poisonous mushroom. Keep a close eye on your pet and watch for any unusual behavior or symptoms such as drooling, vomiting, diarrhea, seizures, or an abnormal heartbeat. If you notice any of these symptoms, contact your veterinarian right away. To prevent poisoning, it is important to remove any mushrooms that you suspect may be toxic.
Wear gloves when handling mushrooms, and dispose of them in a sealed bag in the trash. Be thorough in your removal, ensuring that you get the entire mushroom, including the roots. Another preventative measure is to deny mushrooms the environment they need to grow. Mushrooms thrive in damp, shady conditions, so improving sunlight and airflow in your garden can help prevent their growth. Ensuring your garden has good drainage will also help to reduce the damp conditions that mushrooms favor.
Additionally, you can use mulch or landscaping fabric to create a barrier that will help prevent mushrooms from growing in your garden beds. This barrier will block the sunlight and provide a physical obstacle to mushroom growth. While most mushrooms are not harmful, it is always better to be safe than sorry. If you are unsure about the identity of a mushroom, it is best to err on the side of caution and remove it. By taking these precautions, you can help keep your garden, yourself, and your pets safe from the potential dangers of poisonous mushrooms.

Overwatering can cause mushrooms to grow
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. Mushrooms produce spores instead of seeds, and the origin of the mushroom spores is the gill area underneath the mushroom's cap. Mushrooms thrive in moist and humid conditions. The best way to keep mushroom growth under control in your garden is to watch your watering. Overwatering your garden can cause mushrooms to grow. Mushrooms need water to grow and to keep from drying out. They can only survive in moist and humid conditions.
If your potting soil is infected, it will be challenging to rid it of mushroom spores. To control the mushrooms, you can remove the mushroom caps as soon as they appear. Mature mushrooms release more spores. You can also use fungicide in your garden. If your air is stagnant, employ a small fan to circulate the air. Do not overwater! Keep the soil drier without drying out your plants. Try methods of watering that will keep the first inch or 2 of the soil dry, such as watering the tray of the plant container and allowing the potting soil to soak up the water.
Mushrooms are not necessarily harmful to your garden. They can be a sign of healthy soil. They feed on decaying matter and help keep the soil healthy. They also help compost the soil, turning organic wastes into usable compost for your plants. Mushrooms increase potting soil quality and are beneficial to plants. They should not be dangerous to humans unless a poisonous variety is eaten. Although a few people can be allergic to mushrooms, most people will not be affected if they touch a mushroom directly.
If you do not want mushrooms in your garden, you can remove them by pulling them out by hand, cutting them with gardening shears, or mowing the lawn.
