How to Prevent and Control Fairy Ring

Fairy ring disease causes discolored patches of grass that grow in circles. These patches can be as large as 10 feet wide and can cause significant damage to your lawn if left unchecked. Fairy rings are caused by soil fungi that produce a discolored patch of grass in circles.

Fairy ring disease is one of the most common diseases of lawns and occurs when fungi grow on your lawn. When this occurs, the fungus causes mushrooms to grow on your lawn resulting in fairy-ring disease. The disease is caused by the fungus “Dactylis glomerata.” It attacks several different species of plants, including fescue, winter ryegrass, and pampas grass. It can be controlled and prevented with the right lawn care and maintenance practices.

Here are some things you can do to prevent and control fairy-rings.

1. Remove the Grass

To control , start by removing the grass from the fairy-ring. Cut a one-foot-wide circle around the discolored area and remove the grass. You’ll want to remove about an inch of soil from the center of this circle as well. The fungus will spread underground and will continue to produce a discolored ring if you don’t remove all of it.

2. Reduce Thatch by Mowing the Grass

Excessive thatch can be the cause of fairy-ring disease. You’ll have to mow the grass more often to reduce the amount of thatch in your lawn. Mowing your grass about once a week will keep it low enough for sunlight to reach the roots. This allows healthy grass to grow strong while reducing disease by improving soil conditions.

3. Fertilize Your Lawn

Fertilizing your lawn will allow a larger root system to grow and help prevent fairy-ring disease. This will also help prevent the formation of thatch by improving the soil conditions. A good rule of thumb is to fertilize a lawn at a rate of 1 pound of nitrogen (or other fertilizer) per 1000 square feet of lawn. This will help prevent thatch and also improve the overall health and appearance of your lawn.

4. Aerate Your Lawn

Aerating your lawn is an effective strategy to enhance soil conditions and minimize thatch accumulation, both essential in preventing fairy-ring disease. This process allows sunlight and air to penetrate deeper into the soil, reaching the roots of your grass more effectively. You can use two main types of aerators: power aerators and manual lawn aerators. Power aerators are typically employed for more intensive soil conditioning, as they can deeply puncture the soil, facilitating better water, nutrient, and air flow. On the other hand, manual lawn aerators are more suitable for gently loosening the soil and preventing the formation of thatch over time. Choosing the right type of aerator depends on the specific needs of your lawn. Regular aeration, by whichever means, is a key practice in maintaining a healthy lawn and effectively warding off issues like fairy-ring disease.


Preventing fairy-ring disease is essential in effectively managing this lawn issue. It’s crucial to use lawn treatments, like fungicides or fertilizers, with great care and always in accordance with the instructions provided on the product label. It’s important to note that not all products are suitable for every type of lawn; some may even harm or kill the grass if used improperly. The correct application of these treatments plays a pivotal role in controlling fairy-ring disease. Meticulous attention to product specifications, dosages, and application methods is a key aspect of lawn care that ensures not only the control of fairy-ring but also the overall health and aesthetics of your lawn. You can maintain a lush, healthy, and disease-free lawn by adhering to these guidelines.
