What is the ideal soil pH range for most Maryland turfgrasses?

• A. 5.5-6.5.
• B. 6.8-7.5.
• C. 4.0-5.0.
• D. 7.0-8.0.

Answer: (A)

Soil pH controls how available nutrients are to the grass roots. For most Maryland turfgrasses, a slightly acidic to moderately acidic range provides the best balance, letting essential nutrients be available while avoiding toxicity. In this 5.5 to 6.5 window, roots grow well and nutrient uptake is efficient. If the pH drops too low, aluminum and certain micronutrients become overly soluble, which can harm roots and reduce growth. If the pH rises too high, key nutrients like iron and other micronutrients become less available, causing color and growth problems. So 5.5 to 6.5 is the range that supports steady, healthy turf in Maryland conditions. If a soil test shows you’re outside this range, adjust with lime to raise pH or sulfur to lower it according to the test recommendations, and recheck later to keep the turf in good balance.
