Have you ever noticed an eerily uniform ring of mushrooms in your yard? Or maybe a patch of dead grass that is so perfectly circular that it looks like it could have come out of a scene from the movie Signs? If so, you probably have a fungal disease in your soil called Fairy Ring.
Fairy Ring Folklore
The name Fairy Ring comes from a long trail of European folklore. Some say that the rings come up where the fairies danced the night before. Other cultures believe that they are witches circles and humans are not meant to step into them, lest they be punished. There are many variations of the mythical nature of Fairy Rings but science seems to disprove anything s u p e r n a t u r a l going on here.
The Science Behind Fairy Ring
Fairy Ring is a severe fungal disease that can surely disrupt the American dream of having the best and brightest yard on the block. It starts with a spore that is underground - think of the mold that forms on old bread or food. The tiny individual strands are called hyphae and a colony of those silky tubular structures make up what is called the mycelium. As the mycelium grows outward in a circular structure in search of more nutrients, it depletes the soil in its path. This results in a hydrophobic environment meaning that the soil is unable to retain water. Anything that tries to grow there will eventually die due to lack of hydration and nutrients.
The dead grass indicates the hydrophobic environment that is left after the Fairy Ring has taken it’s course.
Different Signs of Fairy Ring
Since mycelium is an integral part of the soil food web, Fairy Ring is likely to occur almost anywhere, in the right conditions. Some research has said that this phenomenon is stemmed from decaying wood matter of any kind i.e. tree roots, stumps, construction lumber buried underground. Other research states that it is a result from thatch buildup on the surface of the ground. Either way, not all mycelium creates Fairy Ring but all Fairy Rings stem from mycelium.
So what’s the cure, Doc?
From our experience we have found no successful cure for this, unfortunately. Since the issue stems from the mycelium, the only true way to eradicate it would be to dig it completely out of the ground. It is nearly impossible to know if you have successfully gotten every tiny bit of this fungus or not.
Most people do not seek guidance or solutions until their grass starts dying; so, if you have mushrooms or dark green circles, I wouldn’t fret just yet. If/when it does occur, our recommendations are always geared towards practical solutions. Since resodding and pesticide products can be extremely expensive, the most efficient solution would be to install a large bed where the Fairy Ring is. Depending on your style and aesthetic preferences, there are many different routes you can go in terms of what to put in the beds. We would recommend to stay away from planting much in them though because it is possible that they will also be affected by the Fairy Ring. Perennials may be a good choice since they will die off with the changes of the season.
The mushrooms are the fruiting bodies of the mycelium fungi underground.

It’s chinch bug season and truthfully, there is nothing to be excited about here. With the abnormally warm winter we had, it is likely that these pests are larger in number than usual. If these little guys get free reign they can devastate a yard within days. While chinch bugs most commonly affect St. Augustine lawns, they have been known to cause destruction in Bermuda and Zoysia yards as well.
What are chinch bugs?
Appearance: Chinch bugs are very small insects with six legs that only grow to about one-fifth of an inch long. When matured, they have black bodies that are covered with frosty white wings folded over their backs.
Up close picture of the lifecycle of chinch bugs.
The name chinch bug is derived from the Spanish word chinche. This word has come to mean “pest” and is used in many phrases such as tener de chinches la sangre, meaning tiresome or troublesome.
Lifecycle: In early spring, once temperatures reach 70° F, chinch bugs mate. Females lay up to 500 eggs on grass leaves, stems, roots or in other protected crevices over a period of two to three weeks. Each year we can experience up to four generations of chinch bugs.
Damage: In a short amount of time, chinch bugs can destroy large swaths of your lawn. They damage lawns by inserting their beaklike mouth into leaf blades and sucking out the moisture and nutrients, while also adding toxins back into plants. Grass leaf blades will turn yellow on the edges and then brown out in large patches. Chinch bugs love the heat so they tend to start by damaging the parts of lawns closer to hardscape such as driveways, curbs, sidewalks or along the foundation … anywhere it’s very warm.
Identification: Due to their diminutive size, you may not even know you have an infestation until the damage is already done. The best place to look for these insects are on the stems of your grass, near the soil surface. After you sit and watch closely, you’ll be able to spot them crawling around.

Beware of irrigation problems! Since we haven't gotten much rain in the last two weeks and the temperatures have been on a consistant rise, it is definitely time to set the sprinkler system to twice a week. If you are watering consitantly and don't see any signs of chinch bugs, do an irrigation audit to make sure that every part of the lawn is getting proper coverage.
As with any pest prevention practice, a healthy, robust lawn grown in nutrient rich soil is your best defense against most pests and diseases. Insects are opportunistic and will cull weak plants first. Because chinch bugs thrive on excess moisture, be careful not to overwater your lawn. Regular fertilization and soil feedings will help to keep soil biology healthy and beneficial predatory insect populations active.
It’s a bird, it’s a plane…IT’S TAKE-ALL. The cool temperatures and extra rainfall during the spring months might be great for our plants, but they can also create perfect conditions for certain fungal diseases. While a vigorous lawn and healthy soil can deter pests and diseases, even well-cared for lawns can succumb to aggressive diseases, more specifically Take-All Root Rot (TARR).
What is Take-All Root Rot?
TARR is an aggressive fungal disease that is infecting lawns all across North Texas. The disease is in the soil, not the turf. Therefore, TARR can not be eradicated, only controlled. If TARR is left unchecked, it is liable to cause devastating loss to your turf. While St. Augustine is the most susceptible; Bermudagrass, Zoysiagrass and Centipedegrass can all fall victim to the disease as well.
TARR appears irregularly throughout the lawn.
Symptoms of TARR:
- Your grass is slow to emerge in the spring or not greening up at all. There has been significant loss this year in turf that was previously infected with TARR. Check out our recent blog post about the freeze damage.
- Young leaf blades often turn chlorotic (yellow or very pale green). These symptoms are often mistaken for general chlorosis (a nutrient deficiency) or chinch bug damage.
- Biggest difference between TARR and general chlorosis: TARR will cause yellowing in your lawn in much less uniform patches.
- Chlorotic blades quickly fade to brown.
- Large patches up to several feet across will die off in an irregular pattern (as opposed to defined or circular patches).
- The roots will also be dark brown as they begin to rot away.
Our Success Story
Over the past 10 years, trial and error has resulted in a successful, fully organic “kitchen sink” approach at controlling Take-All. Since TARR is a soil-borne fungus, it cannot be eradicated, only controlled. Regular amendments coupled with our Liquid Compost applications really do wonders for managing this disease. It is an ongoing battle that most homeowners are not able to tackle on their own. Don’t be afraid to seek help!
If you notice any of the symptoms listed above, please contact a professional lawn care maintenance team to properly diagnose and offer a treatment plan. TARR can be difficult to treat. The best prevention is good lawn care practices year-round including proper watering, fertilizing and mowing.
