Fairy rings are circles of dead grass or circles of toadstools that spread out across the lawn usually in late summer and autumn. They are caused by colonies of the fungus Marasmius oeades, which lives in the roots of the turf.
Other types of fungi can cause fairy rings, but doesn’t have an effect on turf, and has been known to encourage growth of the grass! Symptoms vary depending upon the type of fungi that you have, however you may see the following symptoms within your lawn:
An irregular ring of dead grass that gradually expands across the lawn.
Directly across from the dead grass, the grass might be greener
Crops of brown toadstools at various times of the year.
Control of Fairy Rings
These toadstools produce vast quantities of spores so there is no point in trying to remove them. In principle you can dig them out going at least 1ft beyond the ring, then reseed or returf.
This is best treated with a professional fungicide, Greengrass operative will advise you on this.
With any of the above problems the best treatment is always to prevent them in the first place. Greengrass offer a complete Lawn Service that will help maintain your lawn in peak condition throughout the year, including treatments and regular cutting. Please call for details.
