Bermuda Grass vs. St. Augustine Grass: Which Should You Choose for Your Lawn?
Choosing the right grass for your lawn can feel overwhelming, especially when debating between Bermuda and St. Augustine grasses. Each grass type has unique strengths, preferences, and a distinct look. Here’s a comprehensive breakdown to help you understand their differences and decide which is the best fit for your yard.
Bermuda Grass vs. St. Augustine Grass: Quick Comparison
Before diving deep, let’s look at the key differences:
- Bermuda Grass: Thrives in full sun, highly drought-tolerant, tough against foot traffic, and forms a dense, fine-textured turf.
- St. Augustine Grass: Prefers partial shade to full sun, softer texture, handles heat well, and establishes faster with wider blades.
Your final decision depends on your region, yard conditions, and what you want from your lawn.
1. Growing Conditions & Climate Preferences
Bermuda Grass
- Sunlight: Needs full sun (at least 6–8 hours a day).
- Climate: Excels in warm climates—hot, humid areas and southern regions are ideal.
- Drought Tolerance: Very high. Recovers quickly from dry spells.
- Soil: Prefers well-drained soils; adapts well but dislikes shade.
- Best For: Open, sunny yards in hot regions.
St. Augustine Grass
- Sunlight: Tolerates shade better. Thrives in partial sun (4–6 hours) but can handle full sun.
- Climate: Loves warmth, especially in humid coastal areas.
- Drought Tolerance: Moderate. Needs more water than Bermuda.
- Soil: Adapts to a variety of soils and can handle salty or alkaline conditions.
- Best For: Yards with dappled shade, proximity to trees, or coastal areas.
2. Appearance: What Will Your Lawn Look Like?
Bermuda Grass
- Texture: Fine, thin blades create a “carpet-like” effect.
- Color: Ranges from rich green to slightly blue-green.
- Growth Habit: Dense and aggressive, spreads quickly via runners (stolons and rhizomes).
- Visual Impact: Perfect for those who want a manicured, golf-course look.
St. Augustine Grass
- Texture: Broad, wider blades that feel soft underfoot.
- Color: Deep green with a lush, vibrant appearance.
- Growth Habit: Forms thick mats quickly, mainly spreads through stolons (above-ground runners).
- Visual Impact: Ideal for those seeking a plush, slightly coarser texture.
3. Maintenance Requirements
Both grasses need care, but there are important differences.
Mowing
- Bermuda: Likes to be kept short; mow at 1–2 inches for the best look. Grows fast, especially in peak season, so expect to mow frequently.
- St. Augustine: Prefer a taller cut—2.5–4 inches. Does not like being scalped, so raise your mower blade.
Watering
- Bermuda: Tough during drought but still needs regular water to stay green. Deep, infrequent watering is best to encourage strong roots.
- St. Augustine: Needs more frequent irrigation, especially in direct sunlight or sandy soils.
Fertilizing
- Bermuda: Hungry for nutrients! Apply fertilizer 2–4 times during the growing season.
- St. Augustine: Less demanding but benefits from regular fertilizing (2–3 times per season). Go easy to avoid excessive thatch.
Weed and Pest Control
- Bermuda: Vigorous growth often crowds out weeds, but susceptible to some fungal diseases.
- St. Augustine: More shade means less weed pressure, but watch for chinch bugs and fungal diseases like brown patch.
4. Durability and Foot Traffic
- Bermuda Grass: Extremely tough. Holds up to frequent play, pets, and foot traffic. Ideal for sports fields or active families.
- St. Augustine Grass: Softer and more delicate. Cannot handle continuous or intense traffic as well as Bermuda.
5. Benefits & Key Challenges
Bermuda Grass
Pros
- Superior sun and drought tolerance.
- Rapid recovery from damage.
- Dense, beautiful turf discourages weeds.
Cons
- Goes dormant and turns brown in winter.
- Needs a lot of sunlight; struggles with shade.
- High maintenance—frequent mowing and fertilizing.
St. Augustine Grass
Pros
- Thrives in partial shade.
- Lush, comfortable underfoot.
- Recovers quickly after moderate damage.
Cons
- Sensitive to colder temperatures (can suffer winter kill).
- Vulnerable to certain pests, especially chinch bugs.
- Needs more water; struggles in severe drought.
6. Establishment: Seeding and Sodding
Bermuda Grass
- Can be established by seed, sod, or plugs.
- Fast to germinate and fill in bare spots.
- Seed is less expensive and ships easily over long distances.
St. Augustine Grass
- Rarely grown from seed; almost always established with sod or plugs.
- Sod brings instant results but costs more and is heavier to ship.
- Plugs fill in slower, but are a cost-effective way to start.
7. Cost Considerations
- Bermuda:
- Seed is affordable with low shipping costs.
- Sodding costs a bit more but still cheaper than St. Augustine.
- St. Augustine:
- Sod and plugs cost more per square foot.
- Shipping sod is pricier due to weight and bulk.
- Tips: Consider buying locally to save on shipping, and compare by square footage rather than price per piece.
8. Practical Tips for Success
- Choose Based on Sunlight: If your yard is shady, lean toward St. Augustine. Sunny, open spaces are best for Bermuda.
- Water Wisely: Adjust your watering schedule to match each grass’s needs—deep and infrequent for Bermuda, more frequent for St. Augustine in full sun.
- Mow at the Right Height: Keeping Bermuda short and St. Augustine tall brings out their best appearance and health.
- Watch for Pests: Inspect regularly and treat quickly, especially for chinch bugs in St. Augustine and fungal issues in both types.
- Consider Traffic: For active families or pets, Bermuda is the more durable pick.
9. Which Grass Is Right for You?
Choose Bermuda Grass If:
- Your yard gets sun most of the day.
- You want a tough, drought-resistant lawn.
- Mowing frequently won’t be a problem.
Choose St. Augustine Grass If:
- Your yard has shade or lots of trees.
- You want a lush, softer texture.
- You can irrigate more regularly and want quick establishment.
10. Summary
Bermuda and St. Augustine are both excellent warm-season grasses, but they thrive under different circumstances. Bermuda is unbeatable for full-sun, high-traffic settings, and hot, dry conditions. St. Augustine excels in yards with partial shade, areas near the coast, or if you value a soft, lush look. Consider your yard’s sunlight, traffic, and maintenance preference, and you’ll have a thriving, beautiful lawn tailored to your needs.
Frequently Asked Questions (FAQs)
1. Can I mix Bermuda and St. Augustine grasses in my yard?
Mixing is possible but not recommended. Bermuda often overtakes St. Augustine in full sun, while St. Augustine does better in shade. Uneven appearance and competition between the grasses can make maintenance more challenging.
2. Which grass handles foot traffic better?
Bermuda grass is much more tolerant of wear and tear. It recovers quickly and is common on sports fields. St. Augustine is softer but can thin out with heavy use.
3. Does either grass stay green all year?
Both are warm-season grasses and typically go dormant (turn brown) in colder months. In mild climates, St. Augustine sometimes stays green longer, but neither remains vibrant through a cold winter.
4. How do I repair damaged spots in each type?
For Bermuda, overseed with Bermuda seed or use plugs. It fills in spots quickly. St. Augustine repairs work best with sod or plugs, since seed options are limited and slower to fill gaps.
5. Which grass is better for shaded lawns?
St. Augustine is the better choice for shaded areas. Bermuda struggles in anything less than six hours of direct sunlight daily.
A healthy, beautiful lawn hinges on matching the right grass to your specific conditions and goals. Whether you choose the sun-loving durability of Bermuda or the shade-friendly plushness of St. Augustine, understanding their unique needs will help you cultivate the lawn you’ve always wanted.
