Fairy Ring in the lawn

Fairy Rings are a common lawn issue that many homeowners encounter, characterized by dark green borders of grass that form circles or semi-circles. These rings are caused by a type of fungus that lives in the affected areas. As the fungal growth spreads, it can lead to the death of the grass within these rings, creating larger bare spots that may attract weeds, which can thrive in both healthy and unhealthy soil conditions.

These mushroom rings are particularly prevalent during the hot summer months. Unfortunately, effective control of Fairy Rings can be challenging. There is currently no known cure, and efforts to remove the affected soil are often futile, as the fungus can penetrate as deep as two feet. Even a small amount of infected soil can lead to the spread of the problem to new areas. While some gardeners attempt heavy fertilization to mask the symptoms, this approach does not eliminate the disease itself.

For those looking for a more effective solution, a more intensive method involves removing the top 24 inches of affected soil and replacing it with high-quality topsoil. After this process, it’s recommended to compact the new soil and reseed or lay fresh sod to restore the lawn. If you spot a Fairy Ring in your yard, taking photographs and consulting an Idaho Certified Nurseryman at The Home & Garden Store can provide you with targeted advice and assistance. Additionally, be mindful of your watering practices, particularly avoiding overwatering at night, as this can exacerbate the issue.
