St .Augustine vs. Bermuda Grass: A Detailed Comparison
What is St. Augustine Grass?
St. Augustine grass, scientifically known as Stenotaphrum secundatum, is a warm-season grass that is native to the Gulf of Mexico and the Caribbean. It is widely used for lawns in tropical and subtropical regions due to its ability to thrive in hot and humid conditions. St. Augustine grass is known for its broad, flat blades and lush, dense growth.
What is Bermuda Grass?
Bermuda grass, also referred to as Cynodon dactylon, is another warm-season grass that is native to Africa. It has become popular in many parts of the world, including the United States, due to its excellent tolerance to heat, drought, and heavy foot traffic. Bermuda grass is known for its fine texture and aggressive growth.
Climate and Adaptability
St. Augustine Grass
St. Augustine grass excels in warm, coastal regions with high humidity and mild winters. It thrives in USDA hardiness zones 8 through 10, where temperatures rarely drop below freezing. This grass variety struggles in colder climates and is not recommended for areas with harsh winters.
Bermuda grass is more versatile and can adapt to a wider range of climates compared to St. Augustine grass. It is commonly found in USDA hardiness zones 7 through 10, tolerating both hot and cold temperatures. Bermuda grass is particularly resilient in drought-prone regions and areas with mild winters.
Growth Habits and Maintenance
St. Augustine Grass
St. Augustine grass has a moderate growth rate and spreads through above-ground stolons, forming a thick and lush carpet-like appearance. It has excellent shade tolerance compared to Bermuda grass, making it suitable for lawns with partial shade. However, St. Augustine grass requires regular mowing and can be susceptible to certain diseases, such as brown patch and gray leaf spot.
Bermuda grass is known for its aggressive growth and rapid spreading through above-ground stolons and below-ground rhizomes. It forms a dense and durable turf that can withstand heavy foot traffic and recover quickly from damage. Bermuda grass prefers full sun and requires frequent mowing to control its growth. It is more drought-tolerant than St. Augustine grass but can turn brown during extended periods of dry weather.
Appearance and Texture
St. Augustine Grass
St. Augustine grass has a coarser texture compared to Bermuda grass, with broader and thicker blades. It has a vibrant green color and provides a lush, carpet-like appearance to lawns. The dense growth of St. Augustine grass helps to choke out weeds and other undesirable plants.
Bermuda grass has a fine texture with narrow blades that create a manicured look. Its color can vary from light green to dark green, depending on the specific variety. Bermuda grass has a low growth habit, which gives it a close-cropped appearance when maintained properly.
Watering and Drought Tolerance
St. Augustine Grass
St. Augustine grass has average water requirements and is less drought-tolerant compared to Bermuda grass. It performs best with regular watering, especially during dry spells. Overwatering, however, can lead to fungal diseases and shallow root growth.
Bermuda grass is highly drought-tolerant and can survive with minimal watering once established. It has deep roots that allow it to access water from lower soil levels. Bermuda grass requires less water compared to St. Augustine grass, making it an excellent choice for regions with limited water availability or water restrictions.
