How to Tell If I Have St Augustine Grass
St Augustine grass is a popular choice for many homeowners because of its lush green color and ability to grow in warm climates. Identifying this grass type correctly can help you take better care of your lawn and troubleshoot issues more effectively. This guide explains how to tell if you have St Augustine grass, step by step, with clear details and helpful tips.
Understanding St Augustine Grass Characteristics
Before identifying St Augustine grass, it’s important to know its main features. This grass type is known for its broad, flat blades and dense growth pattern. It has a distinctive appearance that sets it apart from other grasses like Bermuda or Zoysia.
Blade Shape and Size
One of the easiest ways to recognize St Augustine grass is by its blades. The blades are wide, flat, and typically measure between 1.5 to 3 inches long. They usually have a dull, velvety texture and are softer compared to other types of grass.
Color and Texture
The grass has a vibrant, medium to dark green hue that stays consistent throughout the growing season. The blades are thick and soft to the touch, offering a plush look that feels comfortable underfoot.
Examining Leaf and Blade Features
Leaf Orientation and Growth Pattern
St Augustine grass grows in a dense, spreading manner. The blades tend to grow more upright but overlap each other, forming a lush carpet on your lawn. The root system spreads quickly, making the lawn appear thick and full.
Blade Edges and Margins
The edges of the blades are smooth and rounded, not serrated or jagged. This soft edge is a characteristic trait of St Augustine grass, making it easy to differentiate from grasses with pointed or hair-like leaf margins.
Checking the Grass’s Growth Habit
St Augustine is a stolon-forming grass, which means it spreads through above-ground runners called stolons. These stolons are visible as thin, creeping stems that root at nodes to create new grass shoots.
Presence of Stolons
If you see grass spreading laterally via these thin runners across the soil surface, it’s a good sign you have St Augustine grass. These stolons are usually a few millimeters thick and have a slightly shiny appearance.
Growth Rate and Density
This grass grows rapidly in favorable conditions, quickly filling in bare patches. Its dense growth provides excellent ground cover but can also become invasive if not maintained properly.
Assessing the Color and Shades
Color is a key clue in identifying St Augustine grass. It tends to have a consistent medium to dark green shade, especially in the spring and summer months.
Color Changes During Seasons
The grass remains green most of the year in warm climates, but can turn brown or yellow in cooler weather or during droughts. Healthy St Augustine is lush and vibrant, with no signs of patchiness or discoloration.
Comparing to Other Grass Types
Unlike Bermuda grass, which has finer blades, or Zoysia, which has narrower blades and a different growth pattern, St Augustine’s broad blades and stolonous spreading are distinctive traits.
Using Visual Tools for Identification

Compare your lawn with detailed pictures of St Augustine grass found online. Look for the broad blades, soft texture, and stolon growth pattern in the images.
Consulting a Lawn Expert
If you’re unsure, take a sample of your grass to a local garden center or landscaper. Experts can usually identify the grass type quickly and accurately.
Other Tips for Identification
- Check Soil and Climate Conditions: St Augustine thrives in warm, humid climates with well-draining soil. If your area meets these conditions, it’s more likely you have this grass type.
- Observe Lawn Maintenance Practices: St Augustine requires regular mowing at a height of around 2.5 to 4 inches. Its tolerance for shade is limited, so it often grows best in sunny areas.
- Identify Pest and Disease Signs: Common issues include gray leaf spot or chinch bugs. Noticing these problems may indicate you have St Augustine, as it is susceptible to certain pests and diseases.
Common Misconceptions and Mistakes in Identification
Many homeowners confuse St Augustine with similar grasses like Bermuda or Zoysia. Remember, Bermuda has finer blades and forms a different growth pattern, while Zoysia has narrower blades and forms a tight, button-like turf.
Tips to Avoid Misidentification
- Always compare multiple features—blade size, growth pattern, and texture.
- Use multiple identification methods rather than relying on just one feature.
- If in doubt, seek professional help or send a sample for analysis.
Avoiding Common Lawn Problems Related to Misidentification
Incorrectly identifying your grass can lead to improper care, resulting in pest issues, disease, or poor growth. Knowing your grass type ensures you provide the right fertilizer, watering schedule, and pest control methods.
