Top St Augustine Grass For Shade Recommendations
- Palmetto is a native St. Augustine grass cultivar selected for better color and finer texture than ordinary St. Augustine grass. Palmetto St. Augustine grass demonstrates superior shade, cold, frost, heat, and drought tolerance. This versatile turfgrass is used across the southern United States from the Carolinas to California under a wide range of climate and soil conditions making it the ideal choice for residential and commercial use.
- Palmetto grass is rapidly becoming accepted as a landscaping standard as it has been used in thousands of lawns since 1994. Please note that like all turfgrass, Palmetto St. Augustine grass is a living plant, not a miracle grass. When properly maintained, however, Palmetto St. Augustine grass will deliver years of an aesthetically pleasing and functional lawn.
- Palmetto grass is a semi-dwarf grass, giving it a plush appearance similar to Seville and Delmar, but Palmetto grass is less prone to becoming thatchy, even in full sunlight. The leaf blade width is similar to Bitterblue and Raleigh and finer than Floratam. When mowed high (3" - 4") it is often mistaken for fescue. The leaf blades are tapered at the tip with a rounded end, and are soft to the touch, unlike the prickly feel of Floratam.
- Palmetto grass will remain green longer than any other variety of St. Augustine, and will stay green much longer than Bermuda grass and Centipede grass. Palmetto grass will slowly become dormant after several heavy frosts, and will remain evergreen in temperatures below freezing if there are no hard frosts.
- Palmetto grass has demonstrated very good drought tolerance in field tests. St. Augustine grasses in general are known for their shade tolerance, and Palmetto has exceptional shade tolerance, even when compared to the most shade tolerant varieties of St. Augustine.

Choosing the Right St. Augustine Grass for Shady Spots: A Buyer’s Guide
St. Augustine grass is a popular choice for warm climates. It creates a thick, beautiful lawn. However, it needs sunlight. Finding varieties that handle shade well is important. This guide helps you pick the best option for your shady yard.
Key Features to Look For
When buying St. Augustine grass seed, sod, or plugs for shady areas, look for specific traits. These features tell you how well the grass will survive under trees or next to buildings.
Shade Tolerance Level
- **High Tolerance:** The best varieties can handle 4 to 6 hours of filtered sunlight daily.
- **Low Tolerance:** Some types need much more sun. Avoid these for deep shade.
Growth Habit
St. Augustine grass spreads using runners called stolons. Look for varieties that grow dense quickly. A dense mat helps choke out weeds in lower light.
Color and Texture
Even in the shade, you want a nice-looking lawn. Choose varieties known for deep green color. Texture varies; some feel soft, while others are coarser.
Important Materials and Forms
You will usually buy St. Augustine grass in one of three forms. The form you choose affects how fast you get a full lawn.
Sod (Turf Rolls)
Sod is mature grass laid down like a carpet. This is the fastest way to get shade-tolerant grass established. Quality sod feels firm and has roots growing through the bottom layer of soil.
Plugs (Small Plants)
Plugs are small squares of grass. They cost less than sod. You plant them far apart. They spread over time. Good plugs have healthy, green tops and strong root balls.
Seed
St. Augustine grass is often harder to find as seed compared to other grasses. If you find seed, check the bag date. Fresh seed germinates better.
Factors That Improve or Reduce Quality
The quality of your final lawn depends on the grass you start with and how you treat it.
Factors Improving Quality
- **Variety Selection:** Choosing cultivars specifically bred for shade (like ‘Seville’ or ‘Palmetto’) greatly improves success.
- **Soil Preparation:** Healthy soil provides nutrients. Amend heavy clay soil with compost before planting.
- **Watering Schedule:** Shade often means the soil stays wet longer. Proper, deep watering, rather than frequent shallow watering, builds strong roots.
Factors Reducing Quality
- **Poor Drainage:** If water pools after rain, the grass roots will rot. This is a common killer of St. Augustine in the shade.
- **Over-Fertilizing:** Too much nitrogen forces fast, weak growth that struggles in low light.
- **Mowing Too Short:** Scalping the grass removes too much leaf surface. The grass needs its leaves to capture the limited sunlight available.
User Experience and Use Cases
Homeowners choose shade-tolerant St. Augustine grass for specific areas around their property.
Ideal Use Cases
This grass works well under large, mature trees like oaks or pines. It is also great along the north side of a house where the sun rarely reaches directly. People who want a soft, dense lawn without constant mowing often select this grass.
What Users Say
Users report that while shade varieties need less sun, they still need consistent care. They notice that the lawn might look thinner than a sunny lawn. However, the payoff is a green carpet where other turfgrasses die.
10 Frequently Asked Questions (FAQ) About St. Augustine Grass for Shade
Q: What is the most shade-tolerant St. Augustine variety?
A: Palmetto and Seville are often cited as the best options for handling lower light conditions.
Q: How much sun does “shade-tolerant” St. Augustine really need?
A: Most shade varieties need at least four hours of direct or bright, filtered sunlight each day to thrive.
Q: Can I use St. Augustine grass in deep, full shade?
A: No. Full shade (less than three hours of sun) is too dark. Consider groundcovers instead, as St. Augustine will thin out and die.
Q: How often should I water shade-grown St. Augustine?
A: Water deeply but less frequently than sunny areas. Check the soil moisture first. Overwatering is a major problem in shady spots.
Q: Is sod or seed better for establishing grass in the shade?
A: Sod gives instant results and is generally recommended because it establishes roots faster than seed.
Q: What is the best height to mow St. Augustine grass in the shade?
A: Mow it higher, usually between 2.5 to 4 inches. Taller grass blades capture more available light.
Q: Will my shady St. Augustine lawn grow as thick as a sunny lawn?
A: It will likely be less dense. Less sunlight means slower growth and thinner coverage compared to a lawn receiving full sun.
Q: What is the biggest problem with St. Augustine in the shade?
A: The biggest problem is usually fungal disease caused by excess moisture and poor air circulation.
Q: How do I control weeds in a shady St. Augustine lawn?
A: Because herbicides can stress grass already struggling in the shade, the best weed control is maintaining a dense turf layer through proper mowing and watering.
Q: Does fertilizer help St. Augustine grass grow better in the shade?
A: Yes, but use it sparingly. Use a slow-release fertilizer and apply it less often than you would for grass in full sun.
