What is a fairy ring in grass?
Three types of fairy ring symptoms are observed in turfgrasses: Type I, Type II, and Type III. A Type I fairy ring causes the soil and thatch to become hydrophobic (water-repellant), killing the turf in patches, rings, or arcs. In areas affected by a Type I fairy ring, the thatch and soil are extremely dry and repel water.
What causes fairy rings in the ground?
Fungi is the common culprit behind every fairy ring. 鈥淲hen you see a mushroom fairy ring, it鈥檚 usually by old stumps or wood decaying in soil,鈥?says Lemcke. The fungi (in this case, mushrooms) feed on that decaying matter. Accelerated growth fairy rings result from fungi in the soil that produce a substance that speeds up the growth.
How does a fairy ring plant grow?
The fungi in a Type 1 Fairy ring coats the soil particles with a waxy layer that repels water. The roots of the grass plant are then starved of moisture.
Do fairy rings in lawns cause turf death?
Fairy rings in home lawns do not typically cause turf death and thus are primarily cosmetic problems. They often disappear naturally following a change in environmental conditions. Therefore, waiting for fairy rings to naturally disappear is often the simplest option for management.
