Gaia Green Oyster Shell Flour - 2 KG

Gaia Green Oyster Shell Flour is a Gaia Green mineral soil amendment for reducing soil acidity and supporting a higher soil pH in gardens and landscapes. It’s built for growers who want a simple, natural input that improves soil conditions over time while also supplying calcium.

This product is positioned as a renewable alternative to mined limestone, with a comparable capacity for ameliorating soil acidity. In practical terms, it’s a straightforward soil pH adjustment option for beds and landscapes where the goal is to move away from overly acidic conditions. Gaia Green also notes that a single application can improve soil properties for several years, which makes Oyster Shell Flour a good fit for long-term soil building rather than short-lived, quick-change inputs.

A key benefit of Gaia Green Oyster Shell Flour is that it’s an excellent source of slow release calcium. That calcium contribution supports the root zone in a steady way, aligning with the product’s long-lasting soil improvement focus. The ingredient story stays clean and easy to trust: it is derived from oyster shell flour, with no blended fertilizer complexity and no need to interpret a long list of additives.

Because the purpose is clearly tied to soil acidity and pH direction, the buyer intent stays simple. This amendment is an excellent choice for all gardens where increased soil pH is desired, especially when you want a familiar limestone-style role from a renewable resource. It’s also a practical option for growers who prefer to make targeted, single-input adjustments to their soil program, keeping the approach focused on soil conditions instead of chasing multiple variables at once.

Gaia Green Oyster Shell Flour is suited to gardens and landscapes, and it also fits container contexts such as hanging baskets, potted plants, and planter boxes. It is recognized by Ecocert Canada for use in organic agriculture, supporting organic-minded growing styles that prioritize simple inputs and soil health.

If you’re working with acidic soil and want a renewable resource that is equivalent to limestone for ameliorating soil acidity, Gaia Green Oyster Shell Flour is a clean, mineral-based choice. This product is a strong fit for growers who want slow release calcium and long-lasting soil improvement, with a clear goal of supporting healthier soil conditions and a more favorable soil pH.
