Best Fertilizers Types For Centipede Grass

Centipede grass (Eremochloa ophiuroides) is a low- maintenance, slow-growing, warm-season, grass that is known for excellent heat tolerance properties. Also, it is moderately resistant to many insects and diseases.

It requires moderate levels of nitrogen, potassium, and other micronutrients. Also, it grows best in soil with low pH values (5.5-6).

It requires fertilization to ensure that it grows lush and dense. If the soil pH is higher, it is beneficial to choose a fertilizer that is compatible with alkaline soil. But, it is preferable to do a soil test before fertilization to determine the nutritional deficiencies.

The recommended nitrogen value is one to two pounds per 1000 square feet per year. Avoid using phosphorus fertilizer for established grass unless a soil test indicates its deficiency.
