Screened to a clean and uniform 1–5mm size, these chips provide a slow-release source of calcium carbonate while raising the pH of acidic soils to optimal levels for sensitive plant varieties.
This product enhances both nutrient availability and root health in mineral-rich, alkaline-loving species.
Graded 1–5mm for consistent blending and distribution in soil.
Natural Calcium Carbonate Source: Boosts calcium levels in soil to support healthy plant cell development.
pH Buffering: Helps raise and stabilize soil pH, especially beneficial in acidic environments.
Cleaned for Immediate Use: No dust or debris, reducing mess and making mixing easier.
Ideal for Limestone-Adapted Plants: Perfect for plants that naturally thrive in high-pH, calcareous environments.
For growers of specialized succulents and cacti, including many from limestone-rich regions, the soil’s pH and mineral balance are crucial for thriving growth. These premium limestone chips offer a precise way to modify your mix, delivering slow-releasing calcium and raising the pH to encourage nutrient absorption and prevent common root problems. Their clean, uniform grade ensures ease of use and optimal aeration without compacting your soil blend.
