Bermuda Grass Vs. St. Augustine (Key Differences)

Bermuda grass vs. St. Augustine grass are both excellent warm-season lawn grasses that you can use to add an aura of beauty to your lawn and landscapes.

You’d choose them if you live in a hot climate and want a fantastic lawn. Some people choose to seed or sod with only one of the turf grasses, while others blend the two. But what are the differences between Bermuda grass and St. Augustine grass?

One of their most notable differences is in their leaves. Bermuda grass has small flat leaves and large flat stems, whereas St. Augustine has enormous flat stems and broad, coarse leaves.

What is Bermuda Grass?

Bermuda grass, wiregrass, and scutch grass are all names for Cynodon dactylon, a grass that may be found worldwide.

Europe, Africa, Australia, and much of Asia are all home to this species. It has made its way to the Americas. It is a common invasive species in Bermuda, even though it is not native to the island. It was dubbed “crabgrass” in Bermuda.

The blades are grey-green in color and have rough edges. They are usually 2–15 cm (0.79–5.91 in) long. The erect stems can reach a height of 1–30 cm (0.39–11.81 in). The stems are slightly flattened and often purple-tinged.

The seed heads appear as a cluster of two to six spikes at the top of the stem, each measuring 2–5 cm in length.

Bermuda Grass Identification

The coarse texture of Bermuda grass, as well as its invasive above-ground roots known as stolons, helps to identify it.

The leaf blade joins the leaf sheath; it also has tiny hairs. Its seed head, which resembles a bird’s foot, is its most distinctive feature.

What Is St. Augustine Grass?

Augustine grass (Stenotaphrum secundatum), often known as buffalo turf in Australia and buffalo grass in South Africa, is a tropical and subtropical lawn grass suitable for cultivation.

It’s a low-maintenance grass that grows into a thick, carpet-like sod that crowds out most weeds and other grasses.

Most Caribbean and Mediterranean areas have St. Augustine grass. Tropical climates are ideal for growing it. It’s common in lagoons and marshes, along shorelines, and everywhere there’s a lot of wetness.

Bermuda Grass Vs. St. Augustine

St. Augustine grass has broad, flat blades and is dark green in color. It creates a dense layer by spreading aboveground stolons, often known as “runners.”

Developing and thriving requires at least 5 hours of direct sunlight per day.Bermuda grass grows best in broad sunlight throughout the day. Its growth will be slowed by a reduction in photosynthesis due to less sunshine.
St. Augustine grass is a fertilizer-hungry grass that needs to be fertilized every two months or every ten weeks using a slow-release nitrogen fertilizer.It is recommended that you fertilize Bermuda grass that has been overseeded twice a year, in December and February.
Doesn’t do well in high-traffic areas.Highly resistant to stress and foot traffic.


Like I mentioned earlier, Bermuda grass has small flat leaves and large flat stems, whereas St. Augustine has enormous flat stems and broad, coarse leaves.

The spikelets, which are borne in 4 or 5 slender spikes at the terminals of the erect stems, are used to identify Bermuda grass.

Weed Tolerance

Weed tolerance is high in both St. Augustine and Bermuda grass. They spread quickly and make a dense, complete lawn.

As a result, they can crowd out and destroy weeds on their own, reducing the need for lawn weed treatments.

Frequently Asked Questions
