Gaia Green Diatomaceous Earth - 500 Gram

Gaia Green Diatomaceous Earth is a Gaia Green diatomaceous earth soil amendment for improving nutrient and water holding capacity and supporting healthier soil structure in your growing medium. This natural mineral amendment is a naturally occurring sedimentary rock, chosen for soil-building benefits that show up in both water movement and root-zone air exchange.

Diatomaceous earth is made from the fossilized remains of diatoms, described as silica rich, single-celled algae. In practical terms, that means this product stays simple: one input, one purpose, and a clear role in improving the physical quality of soil and potting mixes. If you want a soil conditioner that focuses on the feel and function of the medium instead of a multi-ingredient fertilizer blend, this is a clean fit.

Gaia Green describes this amendment as encouraging retention of water and nutrients while draining freely in the root zone. That balance matters when you’re trying to avoid a mix that swings between staying too wet and drying too fast. By supporting moisture and nutrient holding without sacrificing airflow, it helps maintain a more consistent environment around roots through typical watering cycles.

Diatomaceous earth is also selected for structure support: it improves soil structure and porosity for better drainage and air circulation. Those are the kinds of upgrades you notice when a bed compacts easily or a container mix feels heavy after repeated watering. Improving porosity supports better drainage, while air circulation supports high oxygen circulation within the growing medium, which is key for keeping the root zone feeling open and responsive.

Gaia Green Diatomaceous Earth is for growers who want a straightforward soil amendment that improves nutrient and water holding capacity, improves soil structure and porosity, and supports better drainage and air circulation in the growing medium. It’s a good fit for gardeners focused on soil-building and long-term medium performance, especially when the goal is steadier moisture behavior and a more breathable root zone.
