Wholesale Diatomaceous Earth Granules Natural Porous MultiSizes Horticulture Potting Medium

These diatomite granules are derived from ancient diatom fossil deposits and processed using a high-temperature calcination and hardening technique. Calcination significantly reduces dust and stabilizes the granule structure, ensuring they do not rapidly disintegrate or turn to powder when watered.

The granules feature an internal honeycomb-like microporous structure that balances drainage and aeration with moisture and nutrient retention: the gaps between granules allow excess water to drain quickly, preventing root suffocation and rot, while the internal micropores absorb water and nutrients, slowly releasing them to the plant roots. The irregular, angular shape of the granules helps maintain spacing within the growing medium, keeping the soil loose over the long term and effectively preventing compaction.

The product undergoes mechanical screening to remove dust and impurities and is available in various uniform particle sizes: 1–3mm, 3–6mm, and 6–9mm. It can be mixed into planting soil to improve the growing medium or used directly as a decorative top-dressing layer for potted plants.

Small packages cater to home gardening enthusiasts and DIY growers, while bulk supplies serve nurseries, greenhouse farms, garden centers, and cross-border e-commerce sellers. Large orders support customized particle sizing and private-label packaging.
