St. Augustine Grass in Full Sun: Tips for a Luscious Lawn

If you live in a warm climate and want a lush green lawn, St. Augustine grass is a popular choice. This grass is a warm-season grass that thrives in hot and humid conditions. However, if your lawn is exposed to full sun, it can be challenging to keep your St. Augustine grass healthy and looking its best. In this article, we’ll give you some tips on how to care for St. Augustine grass in full sun.

Understanding St. Augustine Grass

Before delving into the essential tips, let’s explore the distinctive features of St. Augustine grass in full sun. This remarkable grass variety is characterized by its flat and wide blade shape, creating a visually appealing landscape. With a dense growth pattern, St. Augustine grass in full sun forms a lush carpet-like cover on lawns, particularly thriving in warm and humid climates. Notably, its exceptional shade tolerance makes it a sought-after option for lawns with partial shade.

Now, when considering optimal conditions for St. Augustine grass, the focus shifts to its response to sunlight, especially in full-sun conditions. While it’s known for its shade tolerance, maximizing its potential involves strategic placement in areas with full sun exposure.

St. Augustine grass in full sun, with its flat blade shape, dense growth pattern, and shade tolerance, stands out as an excellent choice for lawns. To elevate its growth potential, consider planting it in areas with full sun exposure, allowing you to enjoy a resilient and vibrant lawn.

Tips for Growing St. Augustine Grass in Full Sun

  1. Water your lawn deeply and infrequently: St. Augustine grass needs about 1 inch of water per week. However, it’s better to water your lawn deeply and infrequently rather than shallowly and frequently. This will help the roots grow deeper, making the grass more resistant to drought.
  2. Fertilize your lawn regularly: St. Augustine grass needs regular fertilization to stay healthy. You should fertilize your lawn every six to eight weeks during the growing season. However, be careful not to over-fertilize, as this can lead to thatch buildup and other problems.
  3. Mow your lawn at the right height: St. Augustine grass should be mowed at a height of 3-4 inches. Mowing too short can stress the grass and make it more susceptible to disease and pests.
  4. Control weeds: Weeds can compete with St. Augustine grass for water and nutrients. Use a pre-emergent herbicide to prevent weeds from germinating, and pull any weeds that do appear.
  5. Provide shade: If your lawn is in full sun, consider planting trees or installing shade sails to provide some relief from the heat. St. Augustine grass can tolerate some shade, and this will help prevent the grass from getting too stressed.

Common Problems with St. Augustine Grass in Full Sun

Even with proper care, St. Augustine grass can still have some problems when exposed to full sun. Here are some of the most common issues:

  1. Drought stress: St. Augustine grass needs regular watering to stay healthy. If your lawn is not getting enough water, the grass can become stressed and turn brown.
  2. Heat stress: St. Augustine grass is a warm-season grass, but it can still be stressed by extreme heat. If your lawn is in full sun, consider providing some shade to prevent heat stress.
  3. Pest infestations: St. Augustine grass can be susceptible to pests such as chinch bugs and sod webworms. Keep an eye out for any signs of infestation, such as yellowing or brown spots on the lawn.


Selecting St. Augustine grass in full sun in warm climates is a wise decision, although cultivating and maintaining it in full sun can present challenges. However, with these essential tips, you can ensure your St. Augustine grass remains robust and looks its best, even when exposed to full sun conditions. Remember to water deeply and infrequently, adhere to a regular fertilization schedule, mow at the appropriate height, implement effective weed control, and consider providing some shade. By diligently following these guidelines, you can cultivate a lush and vibrant St. Augustine grass lawn that thrives in full sun throughout the entire season.
