San Antonio’s hot summer months can be challenging for maintaining a lush, green lawn. Different grass types have varying nutrient needs, and tailoring your fertilization approach can help ensure your lawn thrives. In this post, we’ll provide fertilization advice for the three most common grass types found in San Antonio: Bermuda, St. Augustine, and Zoysia.

 

Bermuda Grass

 

Characteristics

Bermuda grass is known for its drought tolerance and ability to thrive in the heat. It’s a popular choice for San Antonio lawns due to its hardiness and quick recovery from damage.

 

Fertilization Tips

  1. Frequency: Fertilize Bermuda grass every 4-6 weeks during the growing season, which typically spans from late spring to early fall.
  2. Type of Fertilizer: Use a high-nitrogen fertilizer with a ratio like 4-1-2 (e.g., 16-4-8).
  3. Application Rate: Apply about 1 pound of nitrogen per 1,000 square feet each time you fertilize.
  4. Timing: Ensure you fertilize in the morning or late afternoon to avoid the peak heat of the day.
  5. Watering: Water deeply after fertilizing to help the nutrients penetrate the soil and reach the roots.

 

St. Augustine Grass

 

Characteristics

St. Augustine grass is prized for its thick, carpet-like appearance and ability to grow well in both sun and shade. It’s a common choice for residential lawns in San Antonio.

 

Fertilization Tips

  1. Frequency: Fertilize St. Augustine grass every 6-8 weeks from late spring through early fall.
  2. Type of Fertilizer: Opt for a balanced fertilizer, such as 10-10-10, or one with slightly more nitrogen, like 15-5-10.
  3. Application Rate: Apply 0.5 to 1 pound of nitrogen per 1,000 square feet.
  4. Timing: Fertilize early in the morning or late in the evening to reduce the risk of burning the grass.
  5. Watering: Water thoroughly after application to help the fertilizer reach the root zone and to minimize the risk of leaf burn.

 

Zoysia Grass

 

Characteristics

Zoysia grass is celebrated for its dense growth pattern, which helps crowd out weeds. It’s more tolerant of shade compared to Bermuda but also thrives in full sun.

 

Fertilization Tips

  1. Frequency: Fertilize Zoysia grass every 6-8 weeks during its growing season, from late spring to early fall.
  2. Type of Fertilizer: Use a balanced fertilizer or one with a slightly higher nitrogen content, such as 15-0-15.
  3. Application Rate: Apply 0.5 to 1 pound of nitrogen per 1,000 square feet each time.
  4. Timing: Fertilize in the cooler parts of the day, either in the morning or evening.
  5. Watering: Ensure you water deeply after fertilizing to facilitate nutrient absorption and promote deep root growth.

 

General Tips for Fertilizing in San Antonio

 

  • Soil Testing: Before fertilizing, consider conducting a soil test to determine the exact nutrient needs of your lawn. This can help you choose the right fertilizer and avoid over-application.
  • Avoid Over-Fertilizing: Too much fertilizer can lead to nutrient runoff, environmental harm, and can burn your lawn. Stick to the recommended rates.
  • Monitor Weather Conditions: Avoid fertilizing before heavy rains, as this can wash away the nutrients before they have a chance to be absorbed by the grass.
