Question: What is the latest time I can fertilize my centipede lawn?


Answer: Even though it is still warm, it doesn’t mean you can continue to fertilize your lawn. Fertilizers are a combination of nitrogen, phosphorus, and potassium (potash), which are the major essential nutrients that most plants require. The percentage amounts of these nutrients depends on the blend of the fertilizer you purchase.


Nitrogen is needed for foliage growth and green color. Phosphorous promotes growth, and quality of seed, fruit, and flower production. Potassium helps plants overcome drought stress and improves winter hardiness.


During this time of year it’s helpful to make a potassium application to your lawn. Make applications after Sept.1, four to six weeks before the first expected frost. For Bermuda, centipede, and zoysia grasses, apply 1 pound of potassium per 1,000 square feet. Do not make any fertilizer applications to St. Augustine after Aug. 31.
