Mushrooms in your lawn can be unsightly and may indicate that you've been overwatering your grass. Mushrooms thrive in damp and dark conditions, so their presence could mean that your lawn has been overwatered or is draining poorly. However, the relationship between mushrooms and lawn moisture is complex, and other factors such as thatch buildup, buried wood, and poor drainage also contribute to mushroom growth. While mushrooms themselves are mostly harmless, a few species are toxic, and their presence may indicate underlying lawn issues such as fungal diseases like fairy ring. To prevent mushrooms from taking over your lawn, it's essential to address overwatering, improve drainage, and reduce moisture retention by aerating and dethatching your lawn.

What You'll Learn
Mushrooms indicate overwatering and poor drainage
Mushrooms in your lawn are often a sign of overwatering. While they can indicate that your soil is healthy, they can also signal poor drainage. Mushrooms thrive in damp and dark conditions, so if you see them popping up across your lawn, it's likely that you've been overwatering.
Mushrooms are the reproductive part of fungi that live under the soil. They feed on organic matter like decaying leaves, wood, grass clippings, and even thatch, breaking down complex organic materials into simpler substances that plants can use for nutrients. While they can be beneficial, helping to decompose organic matter and release nutrients into the soil, they also indicate that your lawn is too wet.
If you see mushrooms in your lawn, it's important to address the underlying issue of overwatering and poor drainage. This can be done by adjusting your watering schedule and improving drainage through aeration. Watering deeply and infrequently will create a drier environment that is less favourable for mushroom growth.
Aerating your lawn will also help to improve drainage and air circulation. This can be achieved with a tool called an aerator, which creates holes in the soil to alleviate compaction. Removing organic matter that serves as a food source for fungi, such as decomposing leaves and buried wood, can also help to reduce mushroom growth.
In addition to overwatering and poor drainage, other factors such as thatch buildup and excessive nitrogen fertilizer can contribute to mushroom growth. Monitoring your lawn for signs of overwatering and catching problems early can help prevent mushroom blooms. While mushrooms themselves are usually harmless, a few species are toxic, so it's important to identify and remove them safely if you have children or pets.

Mushrooms are a sign of fairy rings
Mushrooms in your lawn can be a sign of overwatering. They thrive in conditions of high moisture, shade, and rich, organic material in the soil. However, the presence of mushrooms can also indicate the existence of fairy rings, which are naturally occurring rings or arcs of mushrooms.
Also known as elf circles, pixie rings, or hexenringe ("witches' rings"), fairy rings are detectable by their distinct patterns of sporocarps (fungal spore pods) and their impact on the surrounding grass, creating a necrotic zone or ring of dark green grass. These rings can grow to impressive diameters, with some of the largest known fairy rings reaching hundreds of meters in size.
The formation of fairy rings is a fascinating process. One theory suggests that fairy rings originate from a spore of the sporocarpus fungus, which grows underground and can cause variations in grass colour or growth above it. Another theory, proposed by Japanese scientists, suggests that fairy rings are formed by neighbouring oval genets of Tricholoma matsutake mushrooms connecting and growing in an arc or ring pattern.
Fairy rings have been the subject of folklore and myth worldwide, particularly in Western Europe. They are associated with supernatural origins and are believed to be portals to another world or signs of underground fairy villages. Some cultures consider them hazardous or linked to witches or the Devil, while others view them as a symbol of good fortune.
To distinguish between overwatering and fairy rings as the cause of mushrooms in your lawn, consider the pattern of growth. If the mushrooms form distinct rings or arcs, it is likely a fairy ring. Additionally, fairy rings are often accompanied by a necrotic zone of dead grass or a ring of dark green grass.

Mushrooms can be removed by hand
Mushrooms in your lawn can be a sign of overwatering, which can waste water and money and pose risks to children and pets. Mushrooms can be removed by hand, along with other methods such as mowing the lawn, using gardening shears, or pulling them out individually. However, it is important to wear gloves when handling mushrooms as their spores can be poisonous. After removing the mushrooms, place them in a plastic bag and discard them to prevent the spores from spreading.
To prevent mushrooms from growing back, you can improve drainage and aerate your lawn using a tool like an aerator, which creates holes in the soil to improve air circulation and drainage. You should also remove any decomposing matter, such as wood chips, small branches, and pet waste, as mushrooms feed off these materials.
Additionally, you should address the underlying cause of the mushrooms, which is often excess moisture. This can be done by adjusting your watering schedule and ensuring your lawn has proper drainage. By following these steps, you can effectively remove mushrooms from your lawn and prevent them from returning.
It is worth noting that while most lawn mushrooms are harmless, some species are toxic and can cause stomach upset in children and pets. Therefore, it is recommended to remove mushrooms from your lawn and avoid taking a chance with potential toxins. Proper lawn care and maintenance can help create an environment less favourable for mushroom growth.

Mushrooms are the reproductive part of fungi
Mushrooms in your lawn are a sign of overwatering. They are the reproductive part of fungi that lives under the soil. Fungi reproduce by forming and releasing spores, which are usually single cells. These spores are produced either directly by asexual methods or indirectly by sexual reproduction. Asexual reproduction is simpler and more direct, with a single individual giving rise to a genetic duplicate of the progenitor without a genetic contribution from another individual. One method of asexual reproduction is budding, which occurs in most yeasts and some filamentous fungi. In this process, a bud develops on the surface of the yeast cell, and the nucleus of the parent cell divides, with one of the daughter nuclei migrating into the bud and the other remaining in the parent cell.
Some yeasts, which are single-celled fungi, reproduce by simple cell division or fission, where one cell undergoes nuclear division and splits into two daughter cells. After some growth, these cells divide, and a population of cells forms. In filamentous fungi, the mycelium may fragment into several segments, each capable of growing into a new individual.
Sexual reproduction is an important source of genetic variability, allowing the fungus to adapt to new environments. It involves the fusion of two nuclei brought together when two sex cells unite. In fungi, the nuclear membrane remains intact throughout the process, although some species exhibit gaps in membrane integrity. The nucleus becomes pinched at its midpoint, and the diploid chromosomes are pulled apart by spindle fibres formed within the intact nucleus.

Mushrooms are a sign of healthy soil
Mushrooms in your lawn can be a sign of overwatering, but they are also a sign of healthy soil.
Mushrooms are the reproductive structures of fungi and indicate that the soil is healthy. Fungi and bacteria play an integral role in the earth. They break down complex organic compounds of proteins, carbohydrates, and fats into their most basic elements that can be used by other generations of organisms. Plants rely on soil fungi and bacteria to digest nutrients for them and, in return, feed soil organisms with sugars they make through photosynthesis.
The fungi that produce mushrooms live in your soil year-round in the form of mycelium: a maze of root-like filaments called hyphae. These hyphae are incredibly helpful. They help break down organic matter into nutrients that plants can use, connect with plant roots to help them access water, and improve soil structure. They even help plants communicate with each other. A healthy fungi population is essential for healthy soil.
Most mushrooms are harmless, but some can be harmful or even deadly if eaten. If you are worried about mushrooms in your yard, you can remove them by raking and burying them in a compost pile. However, they will likely sprout again in a day or so. Using fungicides to get rid of mushrooms is not recommended as it can harm your plants, and the mushrooms will likely return as the fungus mycelium may be several feet below the soil surface.
Overall, while mushrooms in your lawn may indicate overwatering, they are also a sign of healthy soil and can be beneficial to your garden.
