pH Management for Northern Lawns: Lime, Sulfur, and Long-Term Strategy

pH affects every nutrient your grass can or cannot access. Many northern soils run acidic, so lime is often needed (some, especially in the Plains and mountain West, run alkaline, so test first), but over-liming is a common and expensive mistake.

When and How Much Lime

Get a buffer pH test (not just regular pH). It tells you the lime requirement based on your soil’s buffering capacity.

Apply lime in fall or early spring
Never apply more than 50 lbs of lime per 1,000 sq ft in one application
Water it in lightly
Re-test after 6-12 months before adding more

Pro Tip: If your pH is only slightly low, consider using pelletized lime or even wood ash in small amounts. For severely low pH on large areas, hire a professional spreader truck.
