Toadstools In Your Lawn

14th Jan 2015

Toadstools and mushrooms can occur naturally and may appear on any area of a lawn, if certain weather and ground conditions are present.

From time to time, toadstools or mushrooms may be present in a lawn. They only live for a short amount of time and are not too problematic. They are part of the growing environment, and are generally a sign of a healthy, fertile lawn and soil.

The fungi that produce toadstools can recycle dead plant material and will grow very fine threads called mycelium. Upon close inspection, you can sometimes see the mycelium on the leaves of turf. It will look like cotton and disappear as it dries.

Toadstools or mushrooms most commonly appear when the weather is warm and humid, and will usually disappear within a few weeks or when weather conditions change.

Whilst some toadstools are poisonous, the type usually seen on new lawns are harmless, however, humans or animals should not eat them.

Why do toadstools grow in my lawn?

Toadstools appearing in established turf can be due to the soil environment in which they live in, and common causes can include the existence of organic debris under the lawn or active spores waiting for the right conditions. See Scarification for removing debris from your lawn.

How do we treat mushrooms and toadstools?

To identify whether mushrooms and toadstools are going to appear in a lawn, a knife can be used to check under the buried debris of the lawn for infected areas.

To reduce the chances of mushrooms appearing, the lawn can be scarified. This removes thatch and debris underneath, which are the main causes of mushroom and toadstool growth.

Toadstools can be removed by hand or by brushing them off. Alternatively, they can be cut with a lawn mower which has a grass box attached to collect them. Rotary mowers are usually better for this task.

Ask your local Lawn Master outlet to apply a fungicide for the control of mycelium in your lawn. Although we have no specific product for outright control, some fungicides are excellent at removing the problem.

We recently tested a sample of a new product that has been used to treat fairy ring mycellium fungi with good feedback. You can read about the product n our lawn care blog.
