Centipede Fertilizer Guide — Less Is More
Annual nitrogen budget: 0.5-2 lbs N per 1,000 sq ft per YEAR (compare to Bermuda's 2-4 lbs). Best fertilizer: 15-0-15 (equal N and K, no phosphorus). Apply in late spring when lawn is fully green and temps are in the 80s. One application of 0.5 lb N per 1,000 sq ft may be all you need. If lawn needs more, add a second application in mid-summer — but NEVER exceed 2 lbs total N per year. DO NOT use high-nitrogen fertilizers designed for Bermuda. DO NOT use 'Weed & Feed' products — most are too harsh for centipede. For color without nitrogen risk, use chelated liquid iron every 4-6 weeks. Centipede's natural color is APPLE GREEN — lighter than Bermuda. Don't chase dark green with excess nitrogen.
Frequently Asked Questions
How much fertilizer does centipede need?
Only 0.5 to 1 pound of nitrogen per 1,000 square feet per year. One or two light applications during the growing season is all centipede needs. More than 2 lbs of nitrogen per year causes centipede decline.
What fertilizer ratio is best for centipede?
Use a low-nitrogen fertilizer like 15-0-15 or 5-0-20. Avoid high-nitrogen products. Phosphorus is rarely needed unless your soil test shows a deficiency. Potassium helps with stress tolerance.
When should I fertilize centipede?
Apply one light feeding in late spring after full green-up, typically May or June. If a second application is needed, apply in mid-summer. Never fertilize centipede in fall or winter.
Can I use iron instead of nitrogen for centipede color?
Yes, and you should. Iron provides a darker green color without pushing the excessive growth that causes centipede decline. Liquid iron is the preferred way to improve centipede color.
