What Is Saint Augustine Grass


Information About St. Augustine Grass

Bonnie L. Grant, Certified Urban Agriculturist, contributed to this article. St. Augustine grass is a salt-tolerant turf that grows well in subtropical and humid climates, such as Florida. It is commonly cultivated in Florida and other warm-season locations, including California. If the soil is well drained, St. Augustine grass lawns are a compact blue-green color that grows well on a variety of soil types, including clay and sand. St Augustine grass is the most extensively utilized warm-season turf grass in the southern United States, accounting for more than half of all warm-season turf grasses.

Planting St Augustine Grass

Because of its salt tolerance, St. Augustine grass lawns are commonly seen in coastal locations. In addition to being recognized as carpetgrass, St. Augustine produces a smooth, uniform turf that is resistant to extremely high temperatures and low moisture levels. When exposed to chilly temperatures, it preserves its color for a longer period of time than other warm-season grasses and requires less frequent mowing. The most common method of propagating St. Augustine grass is by vegetative means, such as stolens, plugs, and sod.

Augustine grass seed have been ineffective, but new techniques have made sowing a feasible alternative.

  • Augustine grass seed after a lawn has been prepared.
  • m.) once the lawn has been prepared.
  • Augustine grass seed, it is important to keep the soil wet.
  • Plugs should be spaced 6 to 12 inches (15-31 cm) apart on a lawn that has been prepared.

How To Care For St. Augustine Grass

St. Augustine grass is a low-maintenance sod that may function admirably with only a minimal amount of additional care. Following planting, it will require frequent watering, at least three times per day for the first seven to ten days after planting. One the roots have grown, once per day watering at a pace of 14 to 12 inch (6 mm to 1 cm) is adequate to keep the plant healthy. Reduce the frequency of watering gradually until the St. Augustine grass lawn has become well established. After two weeks, cut the grass down to 1 to 3 inches (2.5-8 cm) in height.

During the spring through fall seasons, fertilize with 1 pound of nitrogen every 30 to 60 days.

Common St. Augustine Grass Problems

Grubs and sod worms are the most prevalent pests, and they may be managed with pesticide sprays applied twice a year, once in the spring and once in the fall, depending on the season. Turf diseases caused by fungi, such as brown patch and gray leaf spot, cause the sod to become weak and deteriorate in appearance. Fungicides used early in the growing season may typically capture these diseases before they become a severe problem. Weeds are just a small issue in St.

Augustine. Weeds are crowded out by a healthy grass, and pre-emergence herbicides can be employed in areas where broadleaf weeds provide a continuous danger. In order to avoid difficulties with St. Augustine, it is important to maintain proper cultural management and prevent stress in the turf.

St. Augustine Varieties

There are more than 11 popular St. Augustine variants, as well as numerous freshly released cultivars, to choose between. Some of the most often encountered are as follows: Each variety is developed for improved color and texture, as well as reduced cold sensitivity, pest and disease resistance, and improved flavor and texture. Some dwarf plants, such as Amerishade and Delmar, require less frequent mowing since they are smaller in stature. Classic and Delta Shade are two varieties of St. Augustine grass that have been produced for shade application.

When & How to Plant & Grow St. Augustine Grass

Planting plugs of existing grass is a simple method to get a St. Augustine lawn up and running. It takes time for the plugs, which are rooted pieces of sod, to fill up the spaces between them and create a lush, attractive lawn. St. Augustine sod may be purchased, although it is more costly than other types of sod.

When to Plant St. Augustine Grass

During the warm months of spring and summer, when high temperatures are often 80-100 degrees Fahrenheit, St. Augustine grass thrives at its optimum. Plant St. Augustine grass plugs or sod in full sun at least 90 days before the first expected autumn frost in your location to ensure that the grass has enough time to establish itself and become established.

How to Plant St. Augustine Grass

  1. Calculate the Size of Your Lawn Determine the precise measurements of the area you’ll be planting in order to guarantee that you get enough St. Augustine grass plugs for your needs. It will take around 32 square feet of plugs to cover a tray of 18 plugs. Prepare the Workspace You may rent a sod cutter to remove the old sod and plants from an existing lawn if you are replacing it. In the following step, spray a non-selective herbicide to eliminate weeds 2 weeks before planting
  2. Make sure you choose a product that doesn’t leave a residual that might affect the freshly planted Saint Augustine grass. If you simply have a few weeds here and there, you may hand-pull them
  3. However, make sure to get the entire root system out of the way. In any other case, they will crop up again while your plugs are establishing themselves. Apply EZ PatchTM Lawn Repair to the lawn. Apply Scotts® EZ PatchTM Lawn Repair for St. Augustine Lawns evenly across the planting area, making sure that no bare ground is apparent in the finished product. Scotts® EZ PatchTM contains fertilizer as well as a mulch that may absorb up to six times its weight in water, allowing St. Augustine grass plugs to fill in more quickly. Ensure that the ground is well hydrated. Before you start planting, make sure the area is completely watered. Watering makes the earth more pliable and provides instant moisture to the roots of the St. Augustine grass plugs that have been planted. The water you apply should soak into the soil rather than remaining on the surface. Allow for several minutes’ worth of watering until the EZ PatchTM is totally saturated and no more water is absorbed
  4. This might take several minutes. Start DiggingNow comes the exciting part. Prepare the holes in a diagonal planting pattern, such that each set of four holes makes a diamond shape. The holes themselves should be 12 inches apart from one another (so holes across the center of each diamond will be 15 inches apart). Each hole should be slightly bigger in diameter than the plug’s root ball, but the same depth as the plug’s root ball. A grass plugging tool can also be purchased or rented at a local hardware shop or from an internet retailer. This tool creates perfectly-sized plug-sized holes with a lot less effort on your side than other tools. Put Your Plugs in the Proper Places One plug should be securely inserted into each hole, with each plug being level with the surrounding ground. Alternatively, if your holes wind up being too deep, you may fill in the gaps with a little amount of nutrient-rich soil. Continue to water the plants. Water the plugs once a day or as often as necessary until they are well planted and have begun to spread. It will generally take 7-14 days for the roots to become established in this manner. Following that, water your grass once a week unless you have had a lot of rain. Keep an eye out for bugs and diseases. Lawns of St. Augustine grass that have just been planted require care while they are establishing themselves. Both the roots and the grass are vulnerable to pests and diseases. Keep a tight eye on your grass. If you notice any brown spots or mildew beginning to grow on your plants, contact your local extension service for treatment recommendations.

Maintaining Your New St. Augustine Grass Lawn

As soon as your new St. Augustine grass lawn begins to fill in and the grass blades have reached an appropriate height for mowing, use a mower set to one of the highest settings to trim the grass (3-4 inches). When the leaf blades begin to fold and become bluish-green in color, it is time to water your lawn. Feed your lawn with Scotts® Turf Builder® Southern Lawn Food six to eight weeks after planting. Continue to feed the lawn every 6-8 weeks until the grass has completely filled in on the surface.

Stenotaphrum secundatum, also known asbuffalo turf in Australia and buffalo grass in South Africa, is a warm-seasonlawngrass that is popular for cultivation in tropical and subtropical climates. It is also known as buffalo turf in Australia and buffalo grass in South Africa. It is a medium-to-high-maintenance grass that grows in thick, carpet-like mats, squeezing out most weeds and other grasses in its path of growth.


St. Augustine is a dark green grass with broad, flat blades that grows in the southern United States. It spreads through aboveground stolons, often called as “runners,” and develops a dense coating on the ground. Grass may be found on both sides of the Atlantic Ocean, in areas as diverse as the southeastern United States, Texas, Mexico, Central and South America, and the Caribbean. It has evaded cultivation in California, Hawaii, a number of Pacific islands, South Africa, and New Zealand, among other places.

Augustine grass may be found throughout much of the Caribbean and Mediterranean regions.

It may be found in large numbers in lagoons and marshes, along shorelines, and everywhere there is a lot of water to be found.

Planting and propagation

Because economically useful and viable seed for St. Augustine has just recently been accessible, the plant has traditionally been propagated through plugs, sprigs, or sod instead.

Once the grass has been planted, it will be able to reproduce on its own. St. Augustine can thrive in a broad variety of soil types with pH values ranging from 5.0 to 8.5. It typically blooms throughout the spring and summer months.


St. Augustine grass is a kind of grass that is typically seen in pastures and on ranches. It is a common lawn grass that competes with Bermudagrass in terms of popularity, albeit St. Augustine is somewhat less drought resistant.


A variety of cultivars have been created, including:

  • ‘Captiva’ was a film that was released in 2007. ‘Floratam’ was developed by the University of Florida for its resistance to the southern chinch bug and its dwarf profile, which requires less mowing. It was first introduced in 1973 and has since gained widespread popularity. A cooperation between the University of Florida and Texas A & M University resulted in the development of this product. St. Augustine declines as a result of the viral infection (SAD). ‘Floratine’, which was introduced in 1959, is less cold- and shade-tolerant. It has a deeper hue and a finer texture than the original. It can withstand lower temperatures and requires less mowing. ‘Palmetto’ was a film that was released in the mid-1990s. ‘Raleigh’ is a smaller, lighter green grass that was introduced in 1980. ‘Sapphire’ is a cold-tolerant plant that is also prone to insects and illness. It was first introduced in 2004. It was selected from Australia for its dark blue-green foliage, purple stolons, and quick lateral development, and it was published in 1980 under the name “Seville.” ‘Sir Walter’ is a finer-textured version of ‘Floratam’, which was first released in 1996 and is similar to it. ‘Variegatum’ – in 1993, the Royal Horticultural Society awarded it the prestigious Award of Garden Merit for its ability to thrive in Australian conditions, including heat and drought tolerance
  • ‘Texas Common’ – the most closely related to the natural species, it has fallen out of favor due to its susceptibility to the incurable SAD virus
  • ‘Variegatum’ – in 1993, the Royal Horticultural Society awarded it the prestigious Award of Garden Merit for its It is a spreading evergreen grass with white leaves that have been removed

Facts About St. Augustine Grass

St. Augustine grass may be found throughout the eastern coast of the United States, from the Carolinas to Florida, and along the western coast, from the Gulf Coast to Texas, as well as in Southern and Central California, as well as in the Caribbean and the Caribbean Islands.

It is just the stolons of this perennial turfgrass that are visible above ground, not the rhizomes. In California and other southern parts of the United States, it is commonly known to as “Carpet Grass.” Find out more about the differences between stolons and rhizomes by visiting this page.

St. Augustine Characteristics and Traits

With a very thick grass blade that rounds at the top and becomes more compacted as it gets closer to the soil, St. Augustine grass has a coarse texture and a coarse texture. It has a dark green hue and broad, flat blades that may be arranged in a thick layer to make a dense covering of grass. It does not contain rhizomes, in contrast to bermuda grass, which is its main competitor in the warmer temperatures and tropics of the United States. St. Augustine is a stoloniferous species that takes root at the nodes of the stems and branches.

  • In cooler conditions, it may not perform as well. Those who are less likely to withstand a lengthy drought Unlike other warm-season grasses, it does not tolerate heavy traffic as well. Pests and illnesses are a threat to this crop. Because of over-fertilization, it produces thatch.
St. Augustine Establishment

St. Augustine, like other warm-season turfgrass types, is introduced by the use of sod, plugs, sod pods, or stolons, just like other warm-season turfgrass variations. According to the information previously provided, St. Augustine seed is not a feasible option for lawns. It is not possible to commercialize St. Augustine grasses because they do not generate enough viable seed. Consequently, grass propagation seeds are not manufactured and are thus not accessible for purchase at your local garden shop or other retail establishments.

General Maintenance for St. Augustine

The care of St. Augustine grass varies depending on the season of the year; nevertheless, it should normally be mowed at a height of two to four inches in height. Because you will be mowing less frequently in the autumn and winter months, you should leave your St. Augustine grass a little taller than usual at this time. It will promote deeper root development in preparation for the winter. This may be accomplished by raising the mower height settings by one notch. In addition, your St. Augustine will require around one inch of water each week, including rainfall.

St. Augustine Fertilization

It is critical to fertilize your established St. Augustine grass in order to ensure that your lawn receives the nutrients it requires. If your soil is somewhat acidic, make sure to use a fertilizer that contains iron as well as other micronutrients. Lawnifi’s Fertilizer Program, which includes seasonal boxes for the spring, summer, and fall, is recommended by Sod Solutions.

To accommodate customers who prefer conventional fertilizers, Lawnifi now provides a granular formulation called Lawnifi Foundation. You may find out more about Lawnifi by reading our article entitled Why Use Lawnifi Fertilizer?

St. Augustine Insect and Disease Control

If you see insect damage in St. Augustine, make careful to apply a broad-spectrum pesticide like as Bifen L/P to protect your plants from future infestations. Keep a look out for white grub worms as well. You should be prepared to treat your St. Augustine lawn with a systemic fungicide if you have had a fungal or disease outbreak in the past. This is especially important in the spring and autumn when soil temperatures begin to shift, as this will help avoid repeat outbreaks. St. Augustine grass is a grass that tolerates shade a bit better than other warm-season turfgrasses, although it is not tolerant of full sun.

What to know about St. Augustine grass

Photo courtesy of ILOVETURF.com A homeowner doesn’t pay much care to the turf that makes up their lawn unless it is causing them trouble. However, as a lawn care professional, you are well aware that turfgrass and its many varieties have several intricacies. St. Augustine grass is a warm-season grass that thrives in temperatures between 75 and 90 degrees Fahrenheit. It is a member of the grass family known as the Poa annuas. It is a dark green grass with broad, flat blades that grows in a dense mat.

  • According to the University of Florida, this specific species is particularly popular along the Gulf Coast and is the most often utilized grass in the state of Florida.
  • It also thrives in sandy soil, so those are the conditions in which it thrives.
  • “It will grow in any type of cultural environment you can imagine, with the exception of black shadow, such as on the north side of a home where the sun never shines.” A broad variety of soil types may be used to grow it, and the soil’s pH ranges from 5.0 to 8.5.
  • Augustine grass can only be acquired as sod or plugs, so anyone interested in installing it should look elsewhere.

It is not possible to sell St. Augustine grass seeds commercially since it does not generate enough viable seed. Do not allow your customers to be duped by deceptive sales offers of St. Augustine seeds.

Maintenance needs

When it comes to the sort of maintenance that St. Augustine grass requires, this warm-season grass prefers moisture and should be watered thoroughly. If the leaf blades begin to wilt or become a blue-gray hue, or if footprints are still visible after walking across the grass, the lawn is in desperate need of watering. “Make sure it’s damp,” Orr advises. “People become frugal with their water, especially when there is widespread concern about a water scarcity or a drought, and they will reduce their consumption of water.” St.

Common problems to watch for

In the case of St. Augustine grass, according to Orr, while fungal infections are frequent, they are sublethal to the turf, which means they are mostly aesthetic issues. “Brown patch is the one that I have the most trouble with,” Orr adds. “It generates these big crop circles in the lawn, but it does not destroy the grass; instead, it only knocks off the top leaves, which are immediately replaced by new leaves, and the lawn recovers. However, when it is present, it is really unsightly.” In addition to dollar spot and gray leaf spot, St.

Common mistakes to avoid

Saint Augustine is not the turfgrass to recommend to your clients if they are looking for a warm-season grass that has excellent wear tolerance and drought tolerance. It is not durable enough to withstand regular foot usage. “It’s just not possible to play croquet on a St. Augustine grass,” adds Orr. “That is not what it is intended for.” He claims that the most common error he sees lawn care workers do is something he refers to as “grass leveling.” This is when a lawn care operator looks at the shortest grass on the lawn, sets his mower deck just below that height, and then mows the entire lawn at that height in an attempt to make it seem attractive, as opposed to cutting it shorter.

“It’s difficult to identify when the mow person did it since it takes months, if not a year, for the lawn to die as a result of this low mowing.” “Trying to persuade others is one of the most difficult things in the world.” They believe that a grass must be at least half an inch tall in order to be considered a lawn.

Augustine will die within a year if you mow it down to less than 3 inches in height.” Another concern arises when personnel use string trimmers to bevel the edges of the grass in close proximity to hardscaped surfaces such as sidewalks or roads.

“A lot of it might be resolved by weed eating at the same height as the mower, or at a height that corresponds to the mower height,” says the author.

Advantages & Disadvantages of St. Augustine Grass

St. Augustine grass (Stenotaphrum secundatum) is not the best turfgrass for every situation, and this is true of all turfgrasses. For pastures and lawns in warm coastal settings, this hardy perennial grass provides a dense carpet of coarse, textured grass blades that may be used to cover the ground even in shaded conditions. However, much like any other turfgrass, St. Augustine grass has several disadvantages. Consider the pros and downsides of this grass before investing time and money in a garden or lawn care.

St. Augustine Grass

St. Augustine grass is widely popular across the United States, particularly along the Gulf Coast and in Hawaii. It is also widely grown in Mexico, the Caribbean, South America, Africa, and Australia, among other places. In warm areas, the wide, coarse-textured grass blades offer a beautiful blue-green tint, which contrasts nicely with the surrounding foliage. This turfgrass does not have a preference for soil type and will grow in virtually all well-draining soil types.

Plant hardiness zones 8 through 10 (U.S. Department of Agriculture plant hardiness zones 8 through 10) are suitable for growing it since it can withstand intense summer heat and retain its color.

Advantages of St. Augustine Grass

It is possible that St. Augustine grass will be the best choice for a shaded region that you intend to transform into a lawn. It will perform as well as or better than other warm season grasses when grown in mild shade. It is also extremely salt tolerant, and as a result, it is commonly found growing by the seaside. When properly planted and managed, this warm-season grass may grow into a dense carpet of green. It grows closely enough to allow for moderate quantities of foot movement while also competing well with weeds in the landscape.

Disadvantages of St. Augustine Grass

The only thing that St. Augustine grass can withstand is typical lawn traffic. As a result, it has a low wear tolerance and will not survive in an area where there is a lot of foot traffic. The grass, which is famed for its beautiful blue-green tint, turns brown in the winter when temperatures drop below freezing. Until spring arrives, the turf remains brown or brownish in color. Although St. Augustine grass may withstand moderate shade, it will not grow as thick and lovely as it can in direct sunlight or deep shadow.

Cultivars of St. Augustine Grass

There are various varieties of St. Augustine grass available for purchase in the marketplace. When researching the characteristics of each variety before making a decision, keep in mind that they all have varying degrees of tolerance to environmental pressures and sensitivity to pests and diseases. ‘Floratam’ is a cultivar of St. Augustine grass that has been enhanced and is commonly used in Florida. Although it has low cold and shadow tolerance compared to other cultivars, it does well in locations with at least six hours of direct sunlight each day.

Keep in mind that the dwarf St.

Examine the dwarf cultivar ‘Captiva,’ which not only tolerates chinch bugs better than other varieties, but also produces more fruit.

In comparison to other standard cultivars, ‘DeltaShade’ has a higher shade tolerance than other standard cultivars, but a lower shade tolerance than dwarf cultivars.

It is also said to be able to withstand colder temperatures better than other cultivars of the same species. ‘Palmetto’ is a typical cultivar with a shorter growth habit that thrives in full sun or light shade, but not in deep shadow. It is a good choice for container gardening.

The Different Types of St. Augustine Grass

While living in Florida, St. Augustine grass is considered to be a part of the landscape. It is shorter, broader, and rougher in texture than the grasses found further north in the United States. The individual blades of St. Augustine grass are also sharper than those found in other types of grass, making it difficult to walk on on bare feet in some situations. Despite the fact that St. Augustine grass is quite abundant in Florida, there are several different forms of it. It is critical to understand what sort of grass you have on your lawn since the variety will determine the amount of care you must do to maintain it looking its best.

Augustine grass and how they differ from one another.

Seville St. Augustine Grass

Compared to the usual St. Augustine grass, this grass is regarded to be a dwarf variant. When compared to other types, it has a very fine texture. It has a blue-green hue to it, and it stays this color throughout the year. Even within the St. Augustine family, the Seville species thrives in shadow and drought conditions more than other forms of grass. In the case of a heavily shaded yard, this is an excellent option for you if you are thinking about putting down fresh sod.

It grows well in soils that range from acidic to alkaline in pH, making it suitable for growing in both coastal and inland environments. Due to the fact that this grass requires very little water to survive, it is ideal for individuals who do not want a lawn that takes a great deal of maintenance.

Palmetto St. Augustine Grass

In 1988, a sod gardener discovered Palmetto, a relatively new species of St. Augustine grass that had previously been unknown. It wasn’t until 1994 that the grass was officially released for sale to the general public after extensive research showed that it was safe for lawns of average homeowners to grow on. It is a semi-dwarf grass with a velvety look that grows in clumps. It has less thatch than other types of St. Augustine grass, even when exposed to direct sunlight for extended periods of time.

  • Augustine grasses, this one has a medium-width blade.
  • Walking on Palmetto St.
  • It also retains its green color for the greatest amount of time when compared to any other kind of St.
  • This variety of plant will become dormant if there are multiple frosts in a row, but it will remain green if temperatures are below freezing for only one or two frosts.
  • Shade and drought resistance are second only to Seville St.
  • Seville is able to withstand greater shade and dryness for longer periods of time, although Palmetto is not far behind in this regard.

Floratam St. Augustine Grass

This particular strain of St. Augustine grass was produced in 1972 to combat the St. Augustine Decline (SAD) grass virus that was sweeping over Florida at the time of development. It also had a supplementary role in the development process by proving to be resistant to chinch insect infestations. It thrives in a wide range of climates and has long, thick blades that are easy to cut. The blades of this particular St. Augustine kind are the longest and thickest of any other variety. When seen as a whole, the blades appear coarse and unappealing, yet when examined individually, the lawn appears lush and healthy.

  1. It is also utilized for grazing grass in rural regions when it is available.
  2. Augustine, unlike its cousins in Seville and Palmetto, need a lot of sun and a lot of it.
  3. It should be kept to a maximum height of three inches in order to maintain optimal health.
  4. Augustine grass, is extremely drought tolerant and only requires watering when the grass is visibly withering.
  5. If Floratam begins to lose its color as a result of dryness or freezing temperatures, it will recover fast.

As a result, Florotam thrives in hot and humid climates, making it an excellent choice for lawns in South and Central Florida.

Several of our clients expressed a preference for St. Augustine grass, which is primarily recognized for its lush green appearance and lush green appearance. Unfortunately, more than a quarter of the consumers who purchased it contacted back within the first year to complain about technical difficulties.

Augustine grass is prone to a variety of illnesses and pests, and problems such as the widespread chinch bugs were taking over their lawns and preventing them from enjoying it.

With St Augustine, we began to realize that we would be unable to match our clients’ expectations.

Augustine is a wonderful answer for certain locations, it is not the best option for the communities we serve in Georgia, South Carolina, and North Carolina, which are all in the Southeast.

St. Augustine: The Basics

Let’s start at the beginning and look at some of the advantages and disadvantages of St. Augustine grass: Advantages:

  • Low degrees of upkeep and mowing are required. Creates a thick, carpet-like covering that is effective in competing against weeds and other grasses. It grows well in full sun, although it also tolerates some shade. Tolerates high temperatures and high humidity — making it an excellent choice for Florida, Texas, and other southern regions with subtropical to tropical climates. Because of its saltwater tolerance, it is an excellent choice for coastal locations.


  • Because it is not resilient to cold temperatures, it is only found in climates with moderate winters. Being drought-prone, it is necessary to supplement watering with other sources. Extra fertilizing is required throughout the first three months of growth – this is not your normal “put it and forget it” sort of sod. Are you interested in playing football with the kids? Because St. Augustine does not handle high traffic as well as some other sod kinds, you should reconsider your decision. The plant has a high vulnerability to disease and pests.

Now, let’s talk about the most significant drawback of St. Augustine: it is extremely susceptible to disease and pests. Here are a few illustrations:

Take-All: An Aptly Named Root Fungus

A new disease termed “Take-All Root Rot” (TARR) became significantly more frequent 10 years ago. One of its preferred prey is? St. Augustine grass is a kind of grass native to the United States. Take-All is a fungus that is extremely destructive and produces root rot. While the fungus originates naturally below ground, excessive rains and stressed turfgrass caused by inadequate lawn upkeep stimulate the illness and then the symptoms begin to manifest above-ground. First you will see uneven yellow leaves or light-green areas followed by fading and dying grass.

  1. To our regret, there are currently no effective chemical controls for Take-All Root Rot in residential lawns.
  2. The other important reason is severe rain which cannot be managed.
  3. Augustine lawns and the absence of treatment.

Winter Kill

In addition, St. Augustine is not highly tolerant to low temperatures, making it vulnerable to the blight known as Winter Kill. Winter Kill is caused by a multitude of climatic factors, including cold temperatures, ice and snow on the grass, wind, and moisture levels. Lawns that are unable to green up in the spring are the consequence of a mixture of these factors occurring seldom. Remember the ice and snow storm that hit Atlanta in 2014, which was dubbed “Snowpocalypse”? There were severe winter storm conditions over most of the South that year, and many warm-season lawns did not recover in time for the spring growing season in 2014.

St. Augustine, which is not known for being very winter-hardy, was particularly hard affected. After suffering from Winter Kill in 2014, this St. Augustine grass failed to recover and green up.

St. Augustine grass Decline (SAD)

It is a virus that attacks St. Augustine grass and causes it to become brown. Initially, you will see mottling of the grass blades, which will then be followed by a general yellowing of your lawn. For a few of years, grass may show only modest indications of disease, but as the disease continues, the grass may weaken and become overrun by weeds. Mowers and other lawn equipment have the potential to propagate the SAD virus. Despite the fact that some types of St. Augustine are resistant to the illness, there is now no chemical treatment available.

Chinch bugs

Chinch bugs are little insects that may do significant harm to your grass. And they are quite little, measuring only 1/5″ in length. Chinch bugs actually suffocate your grass to death, and St. Augustine is their favorite place to live!. They eat by inserting their mouth parts into the blades of grass and sucking off the liquids. The poison released by the bugs into the blade causes it to turn yellow and wilt long after the bugs have gone away. Symptoms of chinch bug damage might be mistaken for those of drought or other grass diseases, such as Brown Patch (see below).

As the quantity of insects increases, these islands of dead grass tend to develop and ultimately merge together.

There are also photographs of the insects available on this website.) In most cases, the threshold for treating your lawn is 20 or more chinch bugs per square foot of grass.

The good news is that there are a variety of chemical treatments available for controlling chinch bugs.

Brown Patch

Brown Patch is another another extremely damaging fungus that affects all varieties of grass, including St. Augustine, and is particularly devastating. A summer ailment brought on by high humidity and warm temperatures causes brown, circular patches of grass to appear on the lawn that start off tiny and eventually grow into the form of a doughnut. Then it spreads at a breakneck pace. The use of preventative measures such as avoiding watering your lawn late in the day and not over feeding your lawn with excessive amounts of nitrogen are recommended.

If Brown Patch does appear in your lawn, you can treat it using fungicide sprays that are curative in nature.

Augustine grass has been transformed into a vast stretch of Brown Patch.

Gray Leaf Spot

Gray Leaf Spot is a disease that develops on St. Augustine when the plant is kept moist for an extended period of time – one of the reasons that watering in the early morning is the ideal practice. Find oval/round tan patches on the blades that are encircled by a brown border if you are growing kale.

These areas grow gray and fuzzy as a result of the spores. In their blog article on Gray Leaf Spot in Turf, the North Carolina State Extension provides a full explanation of the problem. On a blade of grass, there are gray leaf spot lesions.

Lethal Viral Necrosis

This new disease first surfaced in Florida, and we learned through the website landscapemanagement.net that it is the result of two viruses combining to form a new sickness. Because the paper didn’t give it a name, merely referred to it as “lethal viral necrosis,” we’re going to stick with that for the time being. Lawns become yellow in the fall and deteriorate over the winter, dying totally in 3 to 5 years. So yet, it has only been discovered in Florida. Because there are currently no known therapies for the disease, it is advised that people take precautions such as cleaning their mowers before entering a new yard to help keep the disease at bay.

There are several more names for St. Augustine. In California, as well as in the Southeastern part of the United States, it is referred to as “Carpet Grass. ”

  • Argentines refer to it as “Gramillion,” which means “million.” “Buffalo Grass” is the name given to this plant throughout Australia and the South Pacific. Crabgrass is the name given to it in the West Indies and Bermuda. It is referred to as “Wire Grass” in St. Helena.

This type of grass does well with a variety of soil types except anything that is waterlogged or is prone to drought conditions. Ideally, though, St. Augustine Grass does best with moist and fairly fertile soils.

In fact, this type of grass does not tolerate cold weather well at all, making it a better choice for places where there aren’t many cold winter days during the year.

St. Augustine cannot make it very far inland, where it’s dry, without irrigation.

However, while this may make it seem similar to Bermuda Grass, it is important to remember that St. Augustine Grass does not contain rhizomes. Compression commonly occurs in the form of compressed stolons or stems, as well as the overlapping leaf sheaths. The real leaf blades are folded at the base, rounded at the tip, and rounded at the tip again at the tip. St. Augustine is a hardy perennial grass that is well-suited for use in pastures and yards. It has a gritty texture and grows in clumps.

Augustine is also a plant that tolerates a lot of shade.

Growing St.

The pH range that works well for this species of grass is 5.0 to 8.5.

Keep in mind, however, that if the pH of the soil is higher than 7.5, this grass is more likely to develop a chlorotic look. Despite the fact that it is not tolerant of soggy or compacted soil, it is extremely tolerant of saline in the soil.

  • When compared to other warm-season grasses, St. Augustine Grass does not tolerate heavy traffic as well as other warm-season grasses. This makes it acceptable for a yard, but not for something more demanding such as a sports field
  • It also works well against weeds and other grasses, and is only affected by a few of the more dangerous pests
  • And it is drought tolerant.

If the climate is drier with 30 inches or less of annual rainfall, it can stillsurvive and provide good grass with proper irrigation. If more maintenance isinvested, the lawn can maintain a dark green, thick, and lush appearance.

Developed by the Florida Agricultural Experiment Station, this particular variety of St. Augustine Grass was introduced onto the market in 1959. There are various characteristics of this grass that distinguish it from the original species. For starters, it has a finer texture and is a darker shade of green than the original. This variety also has a tendency to retain its vibrant color far into the fall and performs better when mowed at a closer distance.

Bitter Blue

Although this particular strain of St. Augustine grass existed before Floratine, it quickly became the preferred kind for lawns until Floratine was developed.


This variety, which was also introduced in 1980 by the North Carolina Experiment Station, was also released in 1980. The distinction is that this particular variety was intended to be a cold-tolerant strain that was also resistant to SAD and other diseases. It has a finer texture than Floratam and grows into a denser grass as it matures. This strain also performs better in the shade, but it does not have the necessary tolerance to chinch bugs.

Texas Common

Since 1920, this kind has been commercially manufactured in the state of Texas.


Seville was designed as a means of coping with SAD and tolerating chinch bugs, among other things. The O.M. Scott and Sons Company published it in 1980, and it has since become a classic. It has a finer texture and is not able to withstand lower temperatures.


The Florida and Texas Agricultural Experiment Stations published this cultivar in 1972, and it has since become widely available. This strand was also engineered to be less sensitive to chinch bugs and the SAD virus, among other things. The blades of this variety of St. Augustine Grass are broader than those of ordinary St. Augustine grass. This species of grass is most widely utilized for pasture grass in South Florida, where it thrives mostly on muck soils. Also, Floratam is not as resistant to cold as the kind found in Texas, therefore it is best suited for growing in locations like as Southern Florida and other coastal zones in the South.

Augustine Grass possess, which is a disadvantage.

Every grass type has pros and cons. Some of how you view them just depends on where you live.For example, one grass may not do well at all in cold weather, like St. Augustine Grass. However, if you live in Florida, this isn’t a concern for you.

  • The Florida and Texas Agricultural Experiment Stations produced this cultivar in 1972, and it quickly became popular. It was also designed to be less sensitive to chinch bugs and the SAD virus than the previous strand. In comparison to regular St. Augustine Grass, the leaf blades of this kind are broader. When it comes to pasture grass in South Florida, this kind is most typically seen on muck soils. Also, Floratam is not as resistant to cold as the kind found in Texas, therefore it is best suited for growing in locations like as southern Florida and other coastal zones in the South. In contrast to several other options for St. Augustine Grass, Floratam does not tolerate the shadow as well as some of the other options do.


  • Frost-sensitive, St. Augustine Grass is not a good choice for growing in the winter. Moreover, it is not drought resistant and would necessitate the use of additional irrigation in arid inland locations. Because of this, it does not tolerate high traffic as well as some of the other warm season grasses available. During the first three months after planting, St. Augustine Grass requires fertilizing
  • Beyond that, it is self-sufficient.
  • It is possible to establish St. Augustine using sod, plugs, or stolons. For the time being, seeding is not a viable choice for establishing a lawn. However, employing stolons expedites the spread of the plant
  • You will need to nourish the plant throughout the establishing stage, which is normally the first three months
  • And you will need to fertilize the plant on a regular basis after that.

The continued success of your St. Augustine lawn depends on its proper management.So for anyone who wants a more maintenance-free lawn, this is not the ideal match.However, if you are situated in a coastal area that gets plenty of rainfall (but not too much or with adequate drainage), you will not need to invest as much care.

During the late fall and early winter, regular mowing is reduced to once or twice a month at most. When it comes to this species of grass, iron deficiency is a regular concern. Drought and cold tolerance of St. Augustine grass have both been shown to be improved by the addition of potassium to their soil. Many pests affect St. Augustine grass, but the chinch bug, which is the most abundant, is the most dangerous. However, in warm regions such as Florida, thesebugs are active all year round and represent a significant hazard.
