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.

For years St. Augustine has been a highly suggested turf variety by professionals in our industry. It is known for its shade tolerance and if healthy, its ability to choke out invasive weeds. When St. Augustine is planted via plugs and in the right growing conditions, it can fill in to near completion in just one growing season. Its leaf blades range from deep to lighter green and its appearance is thick and lush. It seems like there is a lot to love about this turf variety so, is it really all it’s cracked up to be or are we living in the past?
The evolution of St. Augustine in Texas
While St. Augustine is not native to Texas, we have been propagating and planting it here since the 1920’s starting with the Texas Common variety. In the early 1970’s, Florida Texas A&M designed a St. Augustine variety called Floratam that was supposedly SAD (St. Augustine Decline) and chinch bug resistant. This was very appealing because SAD and chinch bugs can cause rapid devastation in lawns and as you may know, replacing your lawn is not cheap and is quite troublesome. In the 1980’s, Floratam was brought to Texas and was planted in mass amounts in the up and coming North Dallas area.
Landscapers and turf businesses soon realized that planting Floratam here was disastrous.This variety was somewhat suitable for the coastal parts of Texas due to its milder climate but was not well suited for North Texas because of it’s lack of cold tolerance. Also considering that Floratam required 2 + more hours of sunlight than the Texas Common variety, it soon became apparent that it was not working as well in shaded areas.
Fast forward 30 years. Since Floratam has been out of the picture, Raleigh and Palmetto St. Augustine grass are on the main stage in North Texas. Raleigh is not known to be chinch bug resistant nor is it as cold tolerant as Palmetto. Therefore, Palmetto is the most recommended here in North Texas. Another attribute of Palmetto is its deep setting root system. Once established, this is beneficial in times of drought and water restrictions.
So what is really SO bad about St. Augustine?
Since the mid 2000’s we have been seeing a steady decline in St. Augustine's performance. We believe that the adaption of insects and diseases to pesticides has played a key role in the decline in St. Augustine along with the 2nd worse fungal issue in our industry- Take All Root Rot (TARR).
TARR before and after Soils Alive treatments
TARR is absolutely devastating to St. Augustine lawns. While it can affect other turfgrasses, St. Augustine is hit the hardest, by and large. Since TARR cannot be eradicated from the soil, it has to be controlled. Industry wide it is recommended to apply pete moss in conjunction with a fungicide to combat this disease. We have found that approach to be ineffective and over the years we have perfected a completely organic “kitchen sink” protocol to control TARR.
While TARR is the most prevalent disease affecting St. Augustine now, there are many others: Chinch bugs, Rhizoctonia aka Brown Patch, SAD, and Grey Leaf spot to name a few.

What turf variety do we recommend?
Zoysia! Zoysia! Zoysia!
Zoysia has many great qualities. One being its unlikeliness to be affected by most pest and diseases. Please know that it can contract diseases although it is not nearly as susceptible as St. Augustine. There are quite a few different varieties of Zoysia and on average it requires about 5 hours of direct sunlight. If looking to plant Zoysia in shade, we recommend one of the thicker bladed varieties like Palisade.
While Zoysia is pretty slow growing, it has a vigorous root system that comes in handy in times of drought. A plus to it being slow growing is that you don’t have to mow as often. All my guys out there say “HEY!”
Lush Zoysia Turf!
Your opinion matters!
As a friendly reminder, this is just our opinion. Some of you may think that St. Augustine is the 8th wonder of the world and if so, stick with it! Everyone has an opinion and preference when it comes to their landscape. Do what makes you happy! And don’t forget … there is no turf that will thrive in dense shade. If you are looking to grow turf in an area that gets little to no sunlight, it is recommended to modify your landscape to accommodate that environment. Otherwise you are fighting a very expensive losing battle.
Finally, it’s warm! YAY! But in true Texan form, we will all be complaining in 3 weeks about how hot it is. Isn’t that an oddity? It never fails, e v e r y s i n g l e y e a r we have something to say about our weather and how we CAN’T BELIEVE that it’s this hot! Didn’t Albert Einstein once say that doing the same thing over and over again and expecting a different result is the definition of insanity? We must be….
Anyway, now that the temperatures are rising what can you be doing to ride the wave of weather change?
Water! Water! Water!
Water is life. Without water we perish, along with any other living organism on this earth. Proper watering practices not only bring life to plants but sustain their health. It can alleviate compaction, nutrient deficiencies and also prevent certain diseases. It is extremely imperative to maintain a balanced watering regimen if you are concerned about the health of your plants. Maintaining this balance will also help reduce the overuse of water and if you are on our Soil Building Program, will allow you to get the most benefit from our treatments.
Over Watering Vs. Under Watering - Is one better than the other?
In regards to turf, it all depends on your variety.
Bermuda responds much better to over watering than under. St. Augustine on the other hand is quite the opposite. Over watering St. Augustine can dig you into a hole that is much harder to get out of than it was to get in. In St. Augustine lawns, overwatering can cause a dreaded fungal disease called Rhizoctonia - AKA Brown Patch. While Brown Patch does not kill the grass, it leaves it leaves an unsightly appearance and the affected areas are slower to green up in the spring.
It is crucial to maintain proper watering practices while still considering what mother nature brings to the table. This can get hard, right? Some of you may never be able to tell if you’re watering enough or too much. Don’t fret! We’ve got a perfect guide that is black and white when it comes to watering your lawn.
Our watering guide is universal for all turf varieties
Weed Alert! Our Summertime Nuisances!
Crabgrass is a thorn in a lot of homeowners’ side come summertime. It usually appears in May and sticks around throughout the end of the year. Crabgrass grows in a clumping manner and the runners branch out much like the legs on a crab. If you prefer to steer clear of chemicals, the best natural way to get rid of crabgrass is to cut it off at the crown (flush with the ground). This kills the weed and leaves the root intact to decompose and feed the soil. Win Win!
Clumps of Crabgrass
Nutsedge made an earlier appearance than normal this year. It usually shows up around May but started popping up in March this year. The blades appear to be long, skinny and dark green. Some may consider nutsedge to be a weed while others respect it as a natural addition to the polyculture that your landscape is intended to be. If you want this weed gone, whatever you do, DO NOT PULL IT. Nutsedge germinates through agitation.
If you are on our program and notice you have nutsedge, give us a call. Nutsedge requires an additional charge to treat but we can eradicate it.
If you see this weed, don't pull it!
Less Is More in Texas Landscapes!
In this day and age we are all about finding ways to make our lives easier. Naturally, that is the reason why most of you hire someone to do your lawn care maintenance for you. If you are one who has a hard time keeping up their end of the lawn care maintenace deal (i.e. watering), try planting Native Texas Plants. Any native varieties require little to no maintenance and are a beautiful addition to any landscape. Some of my favorites are: Texas Sage, Bird of Paradise and Vitex. Hardscapes also call for less maintenance which means spending less money! Plus, weeds and diseases are most of the time non-existent so you can still have the prettiest lawn on the block!
