Fairy rings are a common problem for homeowners and landscapers, causing circular patches of dead or discolored grass in lawns. These rings are typically caused by fungi, and they can be challenging to eliminate. In this article, we will explore the different types of fairy rings, their causes, and the most effective methods for controlling them, including what to spray and how to apply it.
Understanding Fairy Rings
Fairy rings are circular or arc-shaped areas of grass that are either dead or discolored, often with a ring of lush, green growth around the outside. They can range in size from a few inches to several feet in diameter and can be found in lawns, meadows, and other grassy areas. There are several types of fairy rings, including:
Types of Fairy Rings
Fairy rings can be classified into three main types: type 1, type 2, and type 3. Type 1 fairy rings are the most common and are characterized by a ring of dead or discolored grass, with a ring of lush, green growth around the outside. Type 2 fairy rings are similar to type 1, but they have a ring of mushrooms or other fungi growing in the center. Type 3 fairy rings are the least common and are characterized by a ring of dead or discolored grass, with no ring of lush, green growth around the outside.
Causes of Fairy Rings
Fairy rings are typically caused by fungi, such as mushrooms or other types of fungi. These fungi can grow in the soil and feed on the nutrients in the grass, causing it to die or become discolored.
