ST. AUGUSTINE SOD GRASS

St. Augustine sod grass (Stenotaphrum secundatum), also known as buffalo turf in Australia and buffalo grass in South Africa, is a species of grass in the family Poaceae. It is a warm-season lawn grass famous for cultivation in tropical and subtropical regions. It is a medium- to high-maintenance grass that forms a thick, carpet-like sod, crowding out most weeds and other grasses.

St. Augustine sod grass is a dark green grass with broad, flat blades. It spreads through aboveground stolons, commonly known as “runners,” and forms a dense layer.

St. Augustine sod grass occurs on both sides of the Atlantic Ocean, including much of the southeastern United States, Texas, Mexico, and Central and South America. It has escaped cultivation in California, Hawaii, many Pacific islands, South Africa, and New Zealand.

St. Augustine sod grass occurs in most Caribbean and Mediterranean areas. It grows best in tropical climates. It is often seen in lagoons and marshes, on shorelines, and wherever there is a good amount of moisture.

Once St. Augustine sod grass is cultivated, it can propagate on its own.

St. Augustine sod grass can grow in a wide range of soil types with a pH between 5.0 and 8.5. It usually blooms in the spring and summer.

St. Augustine sodgrass is commonly used in pastures and on ranches. It is a popular lawn grass, rivaling Bermuda grass, though St. Augustine is less drought-tolerant.

FAQ: ST. AUGUSTINE SOD GRASS

St. Augustine grass spreads quickly by a creeping root-like system (stolons) above and below ground. St. Augustine grass can be established from sod plugs or stolons that are planted 1–2 feet apart. Plugs or stolons can cover that area in one growing season. Fertilizing will speed up the spreading of St. Augustine grass. 

No more than 1/3 of the height of the grass blades should be removed with any single mowing. Mowing height should be higher during periods of moisture stress or if the grass grows in shade. St. Augustine dwarf varieties have a lower growth habit and should be between 2 and 2.5 inches.

St. Augustine grass grows best in well-draining, sandy, acidic soil with pHs of 5.0 and 8.5. When installing the St. Augustine, use a fertilizer high in phosphorous but low or no nitrogen to help establish the roots. Later, fertilizer with nitrogen was used to improve the St. Augustine growth rate.

St. Augustine grass produces a dense green to blue-green turf that adapts well to most soils and climatic regions in Florida. It tolerates a relatively wide range of soil pH, has relatively good salt tolerance, and certain varieties have better shade tolerance than other warm-season grass species.

St. Augustine grass usually dorms in the winter, even in Florida, but you may still need to water it when it’s warm, dry, and windy. If the average temperature is cool enough to keep the grass dormant for long, you can reduce watering to once or twice a month. You can also raise your mowing height by one inch compared to the summer. 

  • St. Augustine grass is not cold or hardy and can go dormant in the winter, turning brown or tan until spring. It’s best suited for areas with mild winters.
  • St. Augustine grass doesn’t tolerate repeated foot, vehicle traffic, or warm-season grasses.
  • St. Augustine grass is vulnerable to drought and needs extra water, especially during hot weather.
  • St. Augustine grass needs extra fertilizer during its first three months, but too much can lead to thatch buildup and other pest problems.
  • St. Augustine grass is susceptible to pests and diseases, especially chinch bugs. High moisture can also favor disease.
  • St. Augustine grass requires regular mowing and fertilization, and some people don’t like its coarse leaf texture.
  • St. Augustine grass can spread into flower beds and gardens. 

St. Augustine grass requires water to remain green and healthy and may require supplemental irrigation during extended dry periods. It has poor wear tolerance and does not withstand repeated foot or vehicular traffic. In parts of the state, it goes into winter dormancy and turns brown or tan until springtime.

Yes. Turf grasses such as St. Augustine are best-aerated mid-spring through summer. Aerating the St. Augustine turf allows it to grow a dense root system that helps nourish the grass through Florida’s long, hot summers.

They both have pros and cons. Zoysia performs better in shaded conditions compared to St Augustine. Zoysia grass typically requires less mowing and watering, making it a more low-maintenance option for busy homeowners.

During the summer, St. Augustine grass should be watered 2 to 3 times a week, with 0.5 to 0.75 inches of water on each watering. Healthy St. Augustine can only go 1 to 5 days between irrigation events during the summer months, based on the heat index (Myers & Horn, 1969). St. Augustine grass needs even more water. During the winter, St. Augustine grass requires less water once it’s dormant. The best time to water St. Augustine grass is early morning (1:00 am to 3:00 am), before the dew.
