Dolomite Lime Plus 11.8% Magnesium 22.7% Calcium - Soil pH Adjuster

In this review of Dolomite Lime Plus, the bottom line is simple: gardeners who need a reliable, fast-acting way to raise soil pH and add calcium and magnesium will find this product useful. The powder is formulated to deliver 11.8% magnesium and 22.7% calcium, and the reviewer found it effective for improving soil health, supporting larger plants, and reducing blossom rot when used as part of regular soil management. This review focuses on real-world use for compost, worm bins, containers, and in-ground beds rather than on ornamental packaging or fancy claims.

Key Features

• Valuable nutrients: The dolomite provides both calcium and magnesium to replenish depleted soils and support plant development.
• pH adjustment: It raises soil pH to better match the needs of most garden vegetables and ornamentals, improving nutrient availability.
• Compost and worm bin friendly: The powder mixes easily into compost piles and worm bins to stabilize acidity during breakdown.
• Trace elements: Contains minor elements that encourage beneficial soil microorganisms that help plants uptake fertilizer.
• Fast-acting formula: A single treatment can produce noticeable effects on soil condition and plant health in weeks under typical garden conditions.

Who It's For

This product suits vegetable gardeners, tomato growers, and anyone working with container soils or compost who needs to raise pH and add calcium and magnesium without specialty blends. It is particularly helpful where soil tests show acidity or magnesium deficiency and for gardeners trying to reduce blossom rot issues.

Those who should look elsewhere are hobbyists expecting granular slow-release fertilizer action or growers needing a complete NPK fertilizer; this product is specifically a lime amendment and not a balanced feed or a lime substitute for highly alkaline soils.

Pros & Cons

Pros

• Effective at adjusting soil pH and improving soil quality for vegetables and large plants.
• Provides measurable amounts of magnesium (11.8%) and calcium (22.7%) that plants require.

• Encourages beneficial microorganisms, improving uptake of applied fertilizers.

Cons

• As a powdered lime, it can clump if not stored dry and is not a complete fertilizer on its own.
• Not suitable for growers who need an immediate, soluble magnesium boost for foliar feeding.
