What is a Menehune Ring?  In other cultures, these fungi are called fairy rings and there are steeped in myth and lore but have a very interesting science behind them.

Mycelium grows underground and the mushroom is like the fruit of it. When the mycelium takes over a large area, it sucks all the nutrients from the soil in circular patterns that “fruit” on the edges leaving a ring of mushrooms. As the rings grows, it secretes chemicals in the ground and these chemicals break down the organic matter, releasing nutrients so that the mycelium will have food when it reaches this area.

For a short time, the grass at the outer edge of the ring benefits from the nutrients sent out and the extra nutrients make the grass darker green, taller, and thicker than the rest of the lawn. Sadly, this lush grass will die when the mycelium under it, grows and robs the nutrients.

As pretty as they are to look at, these rings are always a sign of lawn problems and decaying matter that isn’t allowed to be used by the grass that needs it.  Contact us if you see one of these rings on your property, and let us help!
