Carpetgrass vs. Centipedegrass: Why the Mix Favors Centipede Long-Term

Carpetgrass in your mix won't persist—it demands constant moisture, fades in summer heat, produces ugly seedheads every 5 days, has poor cold tolerance, and greens up slowly in spring. It's only suited for wet, shady, low-maintenance areas. To favor centipedegrass, fertilize with 15-0-15 after spring green-up and again in midsummer. No fall fertilizer.
