Fertilizing Centipede Grass: Best Practices for Nutrient Management
Fertilizing centipede grass is a crucial aspect of its overall health and vitality. By providing the right nutrients at the appropriate times, you can ensure that your centipede grass lawn thrives and maintains its lush green appearance. In this article, we will discuss the best practices for fertilizing centipede grass based on expert recommendations from reputable sources.
Fertilization Frequency
According to experts, centipede grass should ideally be fertilized either three or four times a year, depending on the specific needs of your lawn. In areas with high rainfall and sandy soils, a higher application rate may be necessary. Here are the recommended fertilization frequencies and rates:
- Three times a year: Apply 1/3 lb of nitrogen per 1,000 square feet during each application.
- Four times a year: Apply 1/4 lb of nitrogen per 1,000 square feet during each application.
Slow-Release Fertilizer
If you prefer using a slow-release fertilizer, a single application in April with a rate of 1 pound of actual nitrogen per 1,000 square feet is sufficient. It is important to ensure that the fertilizer you choose has the appropriate nitrogen content to achieve this ratio.
Readily-Soluble Fertilizer
For those using readily-soluble fertilizers, it is recommended to split the applications into three separate times throughout the year. Here is the recommended schedule:
- April: Apply 0.5 pound of actual nitrogen per 1,000 square feet.
- June: Apply another 0.5 pound of actual nitrogen per 1,000 square feet.
- August: Apply an additional 0.5 pound of actual nitrogen per 1,000 square feet to encourage further growth.
Soil pH
Centipede grass thrives in slightly acidic soil conditions, with a pH level between 5 and 6. Conducting a soil test is essential to determine the pH level of your lawn’s soil. If the pH is too high, sulfur can be added to make it more acidic. Conversely, if the pH is too low, lime can be added to raise the pH. It is crucial to follow the recommendations provided in the soil test report for the appropriate amount of sulfur or lime to apply.
Mowing Height
Maintaining the correct mowing height is important for the health and appearance of centipede grass. It is recommended to maintain a mowing height of 1 to 2 inches. Avoid removing more than one-third of the total grass height during each mowing. For instance, if mowing at a height of 1 inch, try not to let the grass exceed 1.5 inches in height before mowing again.
By following these best practices for fertilizing centipede grass, you can ensure that your lawn receives the necessary nutrients for healthy growth and vibrant green color. Remember to adjust the fertilization frequency and rates based on the specific needs and conditions of your centipede grass lawn.

FAQs
Fertilizing Centipede Grass: Best Practices for Nutrient Management
How often should centipede grass be fertilized?
Ideally, centipede grass should be fertilized three times during the year with 1/3 lb of nitrogen per 1,000 square feet or four times during the year with 1/4 lb of nitrogen per 1,000 square feet. In high rainfall areas with sandy soils, a higher application rate of 2 lb per 1,000 square feet may be necessary.
Can I use slow-release fertilizer for centipede grass?
Yes, you can use slow-release fertilizer for centipede grass. A single application in April with a rate of 1 pound of actual nitrogen per 1,000 square feet is sufficient. Make sure the fertilizer you choose has the appropriate nitrogen content to achieve this ratio.
How should I apply readily-soluble fertilizer to centipede grass?
If using a readily-soluble fertilizer, it can be split into two applications. Apply 0.5 pound of actual nitrogen in April and another 0.5 pound in June. An additional 0.5 pound of actual nitrogen can be applied in August to encourage more growth.
What is the ideal soil pH for centipede grass?
Centipede grass prefers a soil pH between 5 and 6, which is more acidic than what many other plants and turfgrasses prefer. Conduct a soil test to determine the pH level. If the pH is too high, sulfur can be added to make it more acidic. Lime can be added if the pH is lower than 5. Follow the recommendations provided in the soil test report for the appropriate amount of sulfur or lime to apply.
What is the recommended mowing height for centipede grass?
Maintain a mowing height of 1 to 2 inches for centipede grass. Avoid removing more than one-third of the total grass height when mowing. For example, if mowing at a height of 1 inch, try not to let the grass exceed 1.5 inches in height.
Can I fertilize centipede grass during winter?
No, it is not recommended to fertilize centipede grass during winter. Centipede grass goes into a dormant state during winter and does not require additional nutrients. Fertilization should be done during the active growing season.
Should I water the lawn after fertilizing centipede grass?
Yes, it is important to water the lawn after fertilizing centipede grass. Watering helps to activate the fertilizer and allows the nutrients to reach the root zone of the grass. Water the lawn thoroughly, ensuring that the soil is moist to a depth of at least 6 inches.
Can I use a general-purpose lawn fertilizer for centipede grass?
No, it is best to use a fertilizer specifically formulated for centipede grass. Centipede grass has different nutrient requirements compared to other turfgrasses. Using a fertilizer specifically designed for centipede grass will ensure that it receives the appropriate nutrients in the correct ratios.
