Here at Lawn & Weed Expert, we are often asked by both our clients and homeowners why mushrooms sometimes grow on their lawn. We understand that as a homeowner who may not have any knowledge of mushrooms, a sudden outbreak may be cause for concern, however, the professionals at Lawn & Weed Expert are here to tell you it is not! To learn more about mushroom and why they grow on your lawn, read on.   

Why Are There Mushrooms on My Lawn

Mushrooms in your lawn 

Mushrooms, also known as toadstools, are naturally occurring and can sprout up on your lawn given the weather and ground conditions are suitable. They are commonly found in turfed areas as well as pastures, woods and most places where you're likely to find dead plant material. As we mentioned in our opening paragraph, mushrooms shouldn't be a cause for concern and are in fact a sign of a healthy lawn and a part of the growing environment in the form of fungi.

What are fungi?

Fungi are living organisms, neither plant nor animal, but a class of their own. Currently, there are millions of different species of fungi in the world, all with varying characteristics and features. Some are very easy to spot, whereas some are completely invisible and difficult to identify, however, each one is very important and has a big role to play. Fungi exist to help break down organic waste and transform it into plant food, meaning they are recyclers! 

Some fungi have been known to partner with certain plants and attach themselves onto roots, physically feeding the plant with the nutrients they have produced. In return, the plant provides the fungi with sugars it creates from sunlight. 

Why do mushrooms grow on turf?

The soil in your lawn is brimming with fungi and their spores. You can't see them and they won't hurt you, but they are there. They only start to appear when the soil and weather conditions allow them to do so. Mushrooms thrive when the soil is damp and carbon-rich, so often start to sprout after an extended period of rain and cool weather with decaying organic matter in the soil such as leaves, bark and grass clippings. 

Although mushrooms may look unsightly, they are actually beneficial to your lawn. The extensive root system of mushrooms helps the soil to retain water and break down organic materials, which in turn helps to add nutrients back into your lawn. 

The science of mushrooms

Underneath the soil, mushrooms contain many blades which are referred to as 'gills'. Within these gills, there are millions of spores and it is these spores which are responsible for the reproduction of the fungus that you see above the ground. The spores are carried in the air and when they have reached a suitable destination, they begin to germinate and send out long, thin strands or filaments, also known as Hyphae. Single Hyphae are often invisible to the naked eye but can sometimes be seen in particularly dark soil or damp, decomposing bark.

Reducing mushrooms from your lawn

Mushrooms and toadstools can be removed from your lawn by picking them away by hand (wearing gloves as a precaution) or by brushing them off. Alternatively, they can be mown off with a special box on the lawnmower to collect them. There are usually two ways of reducing the development of mushrooms on your lawn:

  1. Decreasing the amount of thatch by scarifying your lawn and then reducing the amount of fertiliser applied to your lawn
  2. Looking for buried debris under your lawn and removing it, preventing mushrooms from growing out of it

It is not possible to completely remove mushroom growth in your lawn as long as there is something decaying in your soil. Besides, removing decomposing materials could actually be more detrimental than helpful.
