A Southern Lawn Favorite

At Mobile Mower Techs, we’re all about helping North Carolina homeowners get the most out of their lawns—from reliable mower maintenance to advice on grass care. Each month, we feature a standout turf type to help you better understand your options and what it takes to grow a great-looking yard. This month, we’re spotlighting St. Augustine grass, one of the most popular warm-season grasses in the southern U.S.—and for good reason.

What Makes St. Augustine Grass Stand Out?

St. Augustine grass is a thick, lush turf that thrives in warm, coastal regions like eastern and central North Carolina. Known for its deep green color and carpet-like texture, it creates a dense, attractive lawn that can handle moderate foot traffic and bounce back quickly from wear.

One of its best qualities is its shade tolerance. While most warm-season grasses need full sun, St. Augustine can perform well in partially shaded areas, making it a great choice for yards with tree cover or nearby buildings.

How to Grow St. Augustine Grass in North Carolina

In North Carolina, St. Augustine grass is commonly established through sod or plugs—it doesn’t produce seeds reliably like other grasses. Here’s how to give it the best start:

  • Timing: Plant in late spring or early summer when soil temperatures are consistently warm.
  • Soil Prep: Make sure the area is well-drained and slightly acidic to neutral (pH 6.0–7.5). Loosen compacted soil before installation.
  • Watering: Keep new sod or plugs well-watered for the first few weeks until roots are established.
  • Sunlight: While it tolerates some shade, St. Augustine still needs about 4–6 hours of sunlight per day for healthy growth.

Once established, it forms a thick mat that helps crowd out weeds and withstands moderate drought with proper care.

Maintenance Tips for a Healthy Lawn

St. Augustine grass is relatively low maintenance if you follow a few key practices:

  • Mowing: Keep your mower blades sharp and cut at a height of 2.5 to 4 inches. Mow frequently enough to avoid removing more than one-third of the blade at a time.
  • Fertilizing: Apply a balanced fertilizer in late spring and again in mid-summer to support strong growth.
  • Watering: Deep, infrequent watering encourages deeper root development. Aim for about 1 inch of water per week, depending on rainfall.
  • Weed and Pest Control: Watch for common pests like chinch bugs and fungal issues during humid months. Treat promptly to prevent damage.

Pros and Cons of St. Augustine Grass

Pros:

  • Excellent shade tolerance
  • Dense growth helps block out weeds
  • Soft, lush feel underfoot
  • Establishes quickly from sod

Cons:

  • Less cold-tolerant than other grasses (can suffer in harsh winters)
  • Requires regular mowing and maintenance to stay thick and healthy
  • Vulnerable to pests like chinch bugs
  • Not typically grown from seed (adds to installation cost)
