Bermuda Lawn pH Guide
Ideal range: 6.0-6.5. pH doesn't directly affect grass — it affects nutrient availability. High pH means grass can't access iron in soil. Low pH: add lime. High pH: pelletized sulfur at 5 lbs per 1,000 sq ft, only when air temps below 75°F, recheck in 3 months, may take several years for large changes. Preferred timing: dormant season.
Frequently Asked Questions
What pH does bermuda grass need?
Bermuda grass performs best at a soil pH of 6.0 to 6.5. At this range, all essential nutrients are readily available for uptake by the root system.
How do I raise soil pH for bermuda?
Apply pelletized lime at the rate recommended by your soil test. It typically takes 3-6 months for lime to fully adjust pH. Retest before applying additional lime.
How do I lower soil pH for bermuda?
Apply pelletized sulfur at 5 pounds per 1,000 square feet when temperatures are below 75 degrees F. Sulfur takes time to acidify soil. Retest in 3 months before making further adjustments.
Should I lime my bermuda lawn every year?
Only lime if your soil test shows pH below 6.0. Unnecessary liming can raise pH too high, locking out nutrients. Always test first — never apply lime on a schedule without data.
