Weird circles in yard..?

Question

About 3 years ago (in my dad's yard) a green circle appeared about a foot in diameter. Now it has grown to about 6 feet in diameter. The edge of the circle is what keeps growing and is darker green in color. The grass inside the circle and out are the same color. It is just a weird ring that my dad thought was from too much fertilizer at one time, but ruled that out once it started growing how it is. Any ideas??

Answer 4

fairy ring also know as necrotic ring is a fungi that seem to show up in yards with unbalanced nitrogen level. One of the best curatives is a fertilization program that may, depending on your region, be 5 to 7 fertilizings a year. This combined with regular mowings will help grow the fungi(mycelium) out

Answer 5

Drunk ground moles

Answer 7

Two thoughts.  One you may have a leaking sprinkler or this is where your sump water is going.

Or that patch may have a different type of grass.  Kentucky Blue or something of the like and it is seeding and taking over.

I know when I have patched grass in my yard with seed, different grass seeds produce different colored grasses.

Answer 8

Answer 14

Unless I miss my guess, you are now faced with Faerie Rings. This fungus causes dark green circles where it is breaking down the nutrients in the soil, resulting in lush growth of the grass immediately over the area of the most current fungus growth. If I am not mistaken, the area immediately behind the green appears to be dead or dying. Which is due to the fact that all the nutrients have been ripped from the ground by the fungus and the rapid grass growth.

Each ring that you see is one single fungus plant and some of these rings can become enormous. Rings 20 and 30 feet across are not unheard of.

Sadly, this fungus is not easy to control. There are a tremendous number of home remedies that have varying degrees of effectiveness. I have heard of everything from pooring bleach on them (Not recommended) to using an Ivory soap solution (uncertain on that one). There are products available that will kill it, but they are by no means cheap.

About the only thing I have seen that works 95% of the time is simply digging the thing out. To do that, you have to dig out the lush growth of lawn PLUS four inches to either side of it. Fill in the hole with soil and reseed or lay sod to cover the bare spot created by the mushrooms removal.
