Fairy Rings can be a common problem in many lawns at some point. They can vary in size from being very small in diameter, to being many metres in diameter.
There are different types of Fairy Rings, which can be categorised as follows:
Type 1 – These types of Fairy Ring are generally classed as the most damaging, as they actually kill the grass that they attack. The dead grass becomes more noticeable, as the grass surrounding it both inside and outside the ring remains unaffected.
Type 2 – This type of ring causes stimulated plant growth by releasing excess nitrogen. The fungi do not kill the grass, but gives it a dark green appearance as a result of the nitrogen
release. These rings are still unsightly but typically do not look as bad visually as the Type 1 fairy ring.
Type 3 – This Fairy Ring type is the most noticeable as it produces mushrooms and toadstools on the surface of the lawn. There are over 60 species of fungi which can cause this type of
Fairy Ring, and it can be surprising how quickly the mushrooms and toadstools appear and spread.
The main problem with Fairy Rings is that they are very difficult to control, due to the nature of the disease. The mycelium creates a waterproof layer in the soil, which means that when chemicals are applied, they usually prove to be ineffective against the disease.
Fairy Rings tend to appear and then disappear from time to time. Overall they do not cause a big problem for most lawns and the problems are usually temporary.
