How do fairy rings get started?
Fairy rings begin when a fungus starts growing in your turf. What causes a fungus to start growing in turf is not clear to scientists, but often grass that has a thatch layer and is growing on natural soils that receive ample moisture, will develop fairy rings. Fairy rings will grow in finely manicured turfs, sports turfs, golf greens, and unmown swards. In general, they grow at a rate of about 75-150mm per year.
