Q: I’ve been trying to find fertilizer for my centipede lawn. Your web site recommends 16-4-8. Could I use a 32-0-10 fertilizer at half strength?
A: Centipede grass is sensitive to high soil phosphorus levels. That’s why 15-0-15 or 16-4-8 are typically recommended. But you’ve found an answer to the grade school question: “Why do I need to learn math?”! Half-strength 32-0-10 equals an application of 16-0-5, which should be fine for centipede grass. Do it twice each year. Don’t forget that a soil test (www.georgiasoiltest.com) can give lots more information on what your lawn needs.
