Usually, mid-May is the best time for fertilization. 15-0-15 ratio fertilizer is the best fertilizer for centipede grass in South Carolina. The 15-0-15 fertilizer bag carries 15% nitrogen, 0% phosphorus and 15% potassium. This fertilizer ratio is also the best fertilizer for centipede grass in Florida.

Don’t use nitrogen during this time. Because of winter durability, it can suggest an incomplete level of potassium. To fill up the shortage of potassium, you can apply one pound of potassium per 1000 sq ft. Apply it 4-6 weeks before the first sleet. Or use two pounds of potassium sulfate per 1000 sq ft.

Mowing Schedule

From January to April, you should mow the lawn a little. The mower blade height should be 1 inch high from the lawn. When the lawn green up, you can reduce the height of the mower but don’t set it too low that it might peel the lawn. 

You can mow the lawn in late April or in early May. Use a sharpened mower blade to cut the grass easily unless if it tears the grass can occur diseases.

Get started with mowing the lawn first from May to August. During this time, you should keep the mower blade height 2 inches high from the lawn. Be careful while mowing the lawn. If the lawn doesn’t look good, then lift the mower blade to the previous length.

From September to December, mow your lawn at a normal height until the temperature decreases in the fall. When the temperature falls to 70° F put up the mower height again into 2 inches.

During the winter season, watering is an important element to eliminate drought stress. Keep an eye on winter rainfall. If there is no rainfall over 3-4 weeks during winter, you have to water the lawn.
