Sunlight is a crucial factor when growing grass in your garden. Inadequate as well as too much sunlight can badly affect the grass’s growth and spread. Thus, it is vital to have an idea about the exact temperature limits that grass can tolerate. In this piece of informative writing, we will be discovering whether St Augustine grass needs sunlight or shade more. If you are considering installing St Augustine grass, this discussion will provide you with a clear insight into one of its basic requirements: sunlight.
Does St Augustine Grass Grow in the Shade?
Yes, St Augustine grass can grow in shade. This grass variety is known for its shade tolerance, making it a popular choice for lawns with varying light conditions.
However, its ability to grow in shade does have limits. While it can perform better in shaded areas compared to many other warm-season grasses, it still requires a certain amount of sunlight to thrive.
Typically, St. Augustine grass needs about 4 to 6 hours of direct sunlight each day.
In conditions where it receives less than this, its growth may be less vigorous, and the grass can become thin and less resilient to other stresses like foot traffic or drought.
The type of shade also matters; dappled shade (like that under open-branched trees) is more favorable than dense shade (like that under thick-canopied trees or structures).
In areas with heavy shade, St. Augustine grass might struggle to survive. In such cases, you will have to incorporate shade-tolerant ground covers or alternative landscaping strategies.
Moreover, regular maintenance, including proper watering, fertilizing, and mowing at a higher height, can also help St. Augustine grass cope better in shaded areas.
If you hope to grow St Augustine in a shady area, make sure to choose one of these shade-tolerant varieties:
- Seville
- Palmetto Sapphire
- CitraBlue
- Delmar
How Many Hours of Sunlight Does St. Augustine Grass Need?
St. Augustine grass needs sunlight for 4 to 6 hours per day.
Although it is known for its shade tolerance among warm-season grasses, it still requires a significant amount of sunlight to maintain health and vigor.
The aforementioned amount of sunlight is crucial for the grass to photosynthesize effectively, ensuring robust growth and a rich green color.
In scenarios where St. Augustine grass receives less than 4 hours of sunlight daily, you may notice it becoming thin, weak, and less able to withstand stresses like heavy foot traffic or drought conditions.
While it can survive in partial shade, the density and growth rate of the grass will be noticeably reduced in such conditions.
Therefore, ensuring adequate sunlight is a key aspect of caring for a St. Augustine grass lawn.
How Can You Grow St. Augustine Grass in the Shade?
When growing St Augustine grass in the shade requires specific care strategies to compensate for the reduced sunlight.
These are some important tips for growing St Augustine in a shaded area.
Choose the Right Variety: Some varieties of St. Augustine grass, like ‘Seville’ and ‘Palmetto,’ are more shade-tolerant. Selecting such a variety can improve your lawn’s performance in shaded areas.
Optimize Sunlight Exposure: Trim tree branches and bushes to allow as much light as possible to reach the grass. Even small increases in sunlight can significantly benefit the grass’s health.
Increase Mowing Height: Mow the grass at a higher setting. The reason why, taller grass blades have more surface area for photosynthesis, which is crucial in low-light conditions.
Water Wisely: Avoid overwatering, as shaded areas tend to retain moisture longer. Too much water can lead to fungal diseases, which are more prevalent in shady, moist conditions.
Fertilize Appropriately: Use a balanced fertilizer but reduce the amount slightly compared to sunny areas. Excessive fertilizer in shaded areas can lead to lush but weak growth.
Limit Foot Traffic: Shaded grass is more susceptible to wear and tear. Thus, it would be better to reduce foot traffic to prevent thinning and compaction.
Regular Aeration and Dethatching: These practices improve soil and root health, enabling better absorption of limited sunlight and nutrients.
Consider Supplemental Ground Covers: In extremely shaded areas, integrating shade-tolerant ground covers with St. Augustine grass can create a more uniformly green space.
