Ever notice those green and brown rings on the turf at a gold course or in your back yard? Those are Fairy Rings. Have no clue what Fairy Rings are? I didn’t either until I did some research.
What are Fairy Rings? Fairy Rings are a type of fungi. There are nearly sixty different species of basidiomycete fungi have been implicated in fairy ring occurrence
Identifying Fairy Rings
-Fairy Rings are those green or brown rings that are often spotted on golf courses and lawns
-Fairy Rings mostly occur during the spring and summer months
-Fairy Rings symptoms may include a ring of mushrooms
- Fairy Rings work by preventing water from reaching the roots. When water doesn’t reach the roots the plant goes into a drought stress.
- Fairy Rings are capable of releasing spores into the wind
- The fungus feeds on organic mater
- Fertilization may mask dark green fairy rings by stimulating growth in the rest of the grass
- Mushrooms may or may not develop after a period of heavy rainfall or irrigation
- Fairy Rings have been deemed the reason why for local dry spots on golf courses
- Fairy Rings can cause the wilting and death of many plants
- Fairy rings are hard to control with fungicides because the soil in the infected area is almost resistant to water
- Fertilizing the land a lot will help to mask the appearance of the dark green growth
- Mowing regularly helps remove mushrooms and other signs of Fairy Rings
- vertical mowing and topdressing to reduce thatch and removal of tree stumps and roots ()
- Aeration and drenching the soil with a wetting agent
- Core aerification with the rotation of multiple fungicides may also help
- Remove the sod infected and replace with new
