Did Too Much Lime Hurt Your Centipede Lawn? Probably Not—Here's Why

The Math Behind the Application

You spread 60 pounds of lime over 4,000 square feet of centipedegrass. That works out to just 15 pounds per 1,000 square feet—well below the 40 pounds per 1,000 square feet typically needed to shift pH in clay soils. In short, you haven't done any harm.

Current pH Recommendations for Centipedegrass

University of Georgia soil labs now advise a target pH of 5.5 to 6.5 for centipede lawns. This slightly acidic range supports optimal nutrient availability while discouraging certain weeds and diseases.

Next Steps: Test, Don't Guess

Instead of applying more amendments blindly, get an accurate soil test through your local Extension office. The University of Georgia offers affordable testing with clear recommendations. Visit georgiasoiltest.com for details on sampling and submission.

Once you have the results, you can adjust pH precisely—if adjustment is even needed.
