Learn how to get rid of fairy rings in lawns without using toxic chemical drenches.
for Fairy Rings
Fairy rings are caused by a diverse family of soil-inhabiting fungi called basidiomycetes. They typically appear as dark green circles in the lawn ranging in size from a few inches to 200 feet or more in diameter. Lush rings of turf are formed by the release of nutrients, in particular nitrogen, from the activity of the fungus living on organic matter in the soil. A circle of mushrooms usually develops around the edge of the infected area.
Fairy rings grow outward at the rate of 6 to 24 inches annually depending on grass, soil and weather conditions. They are most common on sandy soils that are low in water and fertility. Thick thatch layers also contribute to this problem.
Besides being unsightly, fairy rings can cause serious damage to lawns. Often the disease will produce a thick fungal mat that prevents water from reaching the grass roots below. Once the soil becomes dry it is very difficult to wet and the grass roots eventually die. The fungus may also deplete soil nutrients and, in some cases, will release a toxic by-product that can directly kill the turf within a ring.
Note: The name “fairy ring” comes from an old folk-tale. People once believed that the mushrooms appeared where fairies had danced the night before.
