Post category: Fairy rings


Fairy rings on a lawn are caused by a soil fungus feeding off the roots of the lawn grasses. A ring of vigorous green grass may surround a broken ring of bare spots. The rings expand slowly outwards, occasionally producing a few pale brown, small mushrooms.

Fairy rings occur most frequently on good lawns, and can be very disfiguring. Toadstools or inkcap mushrooms are not lawn diseases as such – these are fungi feeding on dead roots, bits of timber or other organic material in the soil – and can be removed by brushing away.

Control of a fairy ring is difficult to achieve. The grass over the rest of the lawn should be well fed to disguise the ring.
