Centipede Grass pH at 6.5: Should You Lower It?

Established centipedegrass tolerates a pH of 6.5 well, even though it prefers more acidic soil. Forcing a rapid pH drop can stress the grass. Instead, let it decline naturally over a couple of years by using acidifying fertilizers containing ammonium nitrate or urea.

Remember, centipede is a light feeder—only one or two fertilizer applications per year are needed. Over-fertilizing causes more problems than slightly high pH.
