Apply pelletized lime to raise soil pH below 6.0

What to Do

If your soil test shows pH below 6.0, apply pelletized limestone at the rate recommended by the test report. Apply in spring or fall, ideally after core aeration, and water in lightly.

Why It Works

Most lawn grasses thrive at pH 6.0-7.0. Below 6.0, key nutrients like nitrogen, phosphorus, and potassium become less available to the grass even if they are present in the soil. Lime (calcium carbonate) neutralizes acidity and restores nutrient availability. Cornell Extension notes you can waste 20-70% of fertilizer in acidic soil.

Tips

• Never apply more than 50 lbs per 1,000 sq ft per application on established lawns.
• Pelletized lime is easier to spread than powdered lime and less dusty.
• pH adjustment is gradual — allow 3-6 months before retesting. Adjust over multiple seasons, not all at once.
