The Best Fertilizer for Centipede Grass: A Comprehensive Guide
Centipede grass (Eremochloa ophiuroides) is a warm-season turf grass known for its low maintenance requirements and ability to thrive in sandy soils with limited nutrients. When it comes to fertilizing centipede grass, it’s crucial to use the right type and amount of fertilizer to avoid overfertilization, which can lead to lawn disease. In this comprehensive guide, we will discuss the best fertilizer for centipede grass and provide useful tips for proper fertilization.
Determine Nutrient Needs
Before applying fertilizer to your centipede grass lawn, it is recommended to conduct a soil test to determine the specific nutrient needs. A soil test will provide valuable information about the pH level and nutrient deficiencies in your soil, allowing you to choose the appropriate fertilizer.
Timing is Key
The ideal time to apply fertilizer to centipede grass is a few weeks after the green-up period, but before temperatures start topping 85°F. This typically occurs in late spring or early summer. It’s important to avoid applying fertilizer until after all danger of frost has passed.
Choose the Right Fertilizer
Centipede grass doesn’t respond well to high doses of fertilizer, so it’s important to use a phosphorus-free fertilizer with a lower nitrogen content. A fertilizer with a ratio such as 15-0-15 or 16-4-8 is recommended for centipede grass. These ratios indicate the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the fertilizer.
Application Frequency
Applying fertilizer twice a year is generally recommended for centipede grass. The first application should be done during or after the spring green-up, while the second application can be done in mid-summer. Be sure to follow the manufacturer’s instructions regarding the application rate and frequency.
Avoid Weed and Feed Products
General-purpose weed and feed products can be harmful to centipede grass. It’s important to use a fertilizer specifically designed and labeled for this type of grass. These fertilizers are formulated to provide the necessary nutrients without harming the centipede grass.
Enhancing Color with Iron Supplements
If your centipede grass shows signs of iron deficiency, such as yellowing or pale leaves, applying iron supplements can help enhance its color. Iron sulfate or chelated iron can be used to correct iron deficiencies. Follow the manufacturer’s instructions for application rates.
