Fairy Rings???? Are you out of your mind??? My yard is not Ferngully!! Sorry for the early '90's cartoon movie reference.
Fairy Rings...They can be serious. Are you prepeared? Fairy rings are caused by dozens of different fungi, including mushrooms and puffballs. These fungi grow
through the thatch and soil, consuming organic matter. They do not affect the turf directly, but they can alter the soil environment, making it unfavorable to turfgrass.
Fairy ring fungi start in the soil or thatch and grow outward, like a patch of mold growing as an expanding circle on a piece of rotten fruit or old bread. When two
or more fairy rings meet, they do not grow together. This leads to a wavy pattern. Large fairy rings can expand several feet per year. The fungi accumulate nutrients as they grow through the soil, then when it is time to reproduce, they send up the mushrooms or puffballs to produce spores. So, every mushroom or puffball you see in the ring is all part of the same fairy ring organism.
Your solution!!!
Fairy rings in taller-cut turf usually do not cause severe damage. If the mushrooms are a nuisance, they can be removed by mowing or raking. Some mushrooms are poisonous, so if children or pets are around removal is a
good idea. If the green rings are a concern, a light application of nitrogen or iron could help mask the symptoms. Do not go over fertilize. Always keep in mind the best fertility practices for the species of turf at the site. If the fairy ring
becomes severe (Type 1), core aerification and watering can help move water to the hydrophobic areas around the roots. Affected areas can be physically removed by trenching out the affected areas, but this is time-consuming.
And if all else fails, a good fungicide from Home Depot will do the trick.
