St. Augustine grass is one of the few grass varieties that can withstand both elevated alkaline and acid levels. Scientifically termed as Stenotaphrum secundatum, it is a coarse, perennial grass, commonly grown in lawns.

Ideal Conditions

St. Augustine is best suited for slightly warmer conditions. It can even survive the highly-damaging ocean saltwater. St. Augustine grass can survive in high sunshine areas too, along with excessive shading. This makes it one of the most durable grasses. However, it is quite sensitive to extreme cold conditions.


St. Augustine grass seeds have been introduced only recently. In the past, the grass could only be planted via sod patches and plugs.

This grass is known to react negatively to waterlogged or highly-compacted soil conditions. However, its high tolerance for soil salinity has made it a famous choice in hotter, tropical climates where not many kinds of grass can survive.

With average levels of soil fertility and drainage, St. Augustine grass does not require too much added nourishment. However, those who want to have thicker-looking blades to their patch of grass can buy specialized St. Augustine grass fertilizers that are now available.

In terms of susceptibility to insect pests, the Southern Lawn Chinch bug is regarded as this grass’s biggest threat.
