Best For

Acidic soils, moss-prone lawns, gardens with poor nutrient response, and soil test–driven pH correction.

What Makes It Different

Lime is different from fertilizers because it doesn’t “feed” the plant directly—it corrects soil chemistry so plants can access nutrients more effectively. Dolomitic lime also supplies magnesium in addition to calcium, which is valuable in soils that are both acidic and magnesium-poor. This makes it a targeted soil correction tool that improves the performance of your entire lawn and garden nutrient program.

Why This Fertilizer?

Dolomitic lime is used to improve soil conditions by adjusting soil pH and supplying essential minerals. Over time, soils can become acidic due to rainfall, fertilizer use, and natural soil processes. When soil pH drops too low, plants may struggle to absorb nutrients effectively. Dolomitic lime helps raise soil pH to a more balanced range while also providing calcium and magnesium, two nutrients important for plant health. Correcting soil acidity improves nutrient availability and supports stronger root development. By improving overall soil conditions, lime applications help create an environment where lawns and garden plants can grow more vigorously.

Technical Details

Soil pH strongly influences nutrient availability and plant growth. Many nutrients become less available to plants when soil pH falls outside optimal ranges. Dolomitic lime supplies calcium and magnesium while raising soil pH in acidic soils. Research conducted through the University of Guelph Turfgrass Institute indicates that correcting soil acidity improves nutrient uptake and overall plant health.

Maintaining balanced soil pH allows turfgrass roots to absorb essential nutrients more efficiently. Studies summarized by the Penn State Center for Turfgrass Science show that proper soil pH management is an important component of long-term turfgrass fertility programs.
