Fairy Ring
- Do you see rings or arcs of dark green in your turf?
- Do you see rings or arcs of mushrooms?
- Have the rings or arcs been there for a number of years?
If the answer to these questions is yes, then you could have fairy rings in your turf.
What are Fairy Rings?
Fairy rings are a group of diseases in turf caused by beneficial fungi that breakdown dead and decaying plant material. Thatch is a mat of dead plant material; and the fairy ring fungi can live and grow in it. They decompose dead plant material, but generally they do not attack living turf.
General description of a Fairy Ring
The most common type of fairy ring can be recognised in turf because it causes the turf to grow dark green in colour, in a ring or arc. They measure between 75-200mm wide as an arc and up to a metre in diameter as a ring, gradually expanding across the turf. Crops of brown toadstools may appear at certain times of the year.
Why has it affected my turf?
A Fairy ring begins when a fungus starts growing in your turf. While the causes are not clear, grass that has a thatch layer and is growing on natural soils that receive ample moisture will develop fairy rings.
What can you do about Fairy Rings?
You can reduce the possibility of having a fairy ring by purchasing a good quality turf and preparing your soil properly before installing turf or seed.
When you have a fairy ring in your turf you can fertilise your grass to reduce the appearance of the fairy ring, aerate your grass to allow water to reach the grass roots in the fairy ring or you can dig out and replace the soil to a depth of 300mm, but this is difficult and is not recommended.
Can I control it chemically?
No fungicides are available which provide a consistent result.
