St. Augustine is the most shade-tolerant of the warm-season grasses so if shade is an issue in your project, this might be the variety to choose. It is most commonly used as a lawn grass. Although St. Augustine can be grown in most of Texas, you might have to use supplemental irrigation in Central and West Texas. It may also be killed during a period of severe cold in the northern third of the State. Maintenance requirements are usually low.

Raleigh St. Augustine Turfgrass Sod

Raleigh St. Augustine grass, which is a cold-hardy St. Augustine grass cultivar, was first discovered on a lawn in Raleigh North Carolina and released to the public by North Carolina State University in 1980.  It has a medium green color with a coarse texture. The most common installation method of sodding or plugs; seeds are very difficult to obtain if not impossible.  Compared to finer textured grasses like bermudas, St. Augustine has large flat stems and broad coarse leaves.  It has an attractive blue-green color and forms a deep, fairly dense turf.  It spreads by long above-ground runners or stolons.  While it is aggressive it is easily controlled around borders (www.american-lawns.com)

Potential disease problems are gray leaf spot in the summer and brown patch in the fall; both of these diseases are enhanced by overwatering and after fertilization.  Potential insect problems include chinch bugs.  This insect becomes active during hot dry periods.  They are first detected by brown patches in the lawn that do not recover after watering.  A variety of liquid and granular insecticides are available to control chinch bugs.  Make an application to the entire lawn and water thoroughly to eliminate the problem.  SEE TIPSHEET FOR ADDITIONAL CARE INSTRUCTIONS.

 

Palmetto St. Augustine Turfgrass Sod

Palmetto St. Augustine has a finer textured leaf and stolon when compared to Raleigh.  This tighter leaf spacing gives it a thicker look.  St. Augustine grasses in general are known for their shade tolerance, and Palmetto has exceptional shade tolerance, even when compared to the most shade tolerant varieties of St. Augustine.  In fact, this is the primary reason why palmetto was initially developed in both field shade tests under trees and laboratory testing under canopies of mesh.  When several other varieties of St. Augustine gradually declined, Palmetto sod thickness decreased only slightly and maintained a pleasing overall appearance with consistent color among areas exposed varying amounts of light. Palmetto St. Augustine grass can perform well in shaded areas but must be established and maintained properly.  Please note that like all turfgrass Palmetto is a living plant, not a miracle grass. 

Palmetto will remain green longer than any other variety of St. Augustine, and will stay green much longer than Bermuda grass. Palmetto also greens up very early in the spring. Palmetto has demonstrated very good drought tolerance in field tests (www.american-lawns.com).

Floratam St. Augustine Turfgrass Sod

Floratam St. Augustine grass was released in the early 1970s by the Florida and Texas agricultural experiment stations as a chinch bug resistant turfgrass (hence the name FLORidaand TexasAM).  Floratam is a vigorous, coarse textured St. Augustine grass variety.  Stolons of Floratam are large, purplish-red in color with internodes averaging 3 inches in length.  Leaf blades are wider and longer than common St. Augustine grass.  Floratam is not as cold tolerant as common St. Augustine and may suffer freeze damage when temperatures fall below freezing for extended periods.  According to James Beard, TAEX turf researcher, tests at A&M concluded it is the most drought tolerant of all St. Augustine grasses (www.american-lawns.com).  In recent drought studies it has shown a drought tolerance comparable to Buffalo grass.
