At Jersey Shell Company, we’re passionate about sustainability and innovation. Our mission is to transform what would otherwise be waste—locally sourced oyster shells—into high-quality, eco-friendly gardening products. Based in Jersey, we are proud to contribute to the island’s circular economy by creating natural solutions that support healthy soil and vibrant plant growth.

Our two flagship products are:

• Oyster Shell Soil Improver – A mineral-rich soil additive made from crushed, cleaned, and processed oyster shells. It helps improve soil structure, pH balance, and nutrient availability, making it ideal for gardeners and growers who want to enrich their soil naturally.

• Boost Spray – A liquid plant tonic derived from the same shells, designed to support plant health and vitality. It’s easy to apply and perfect for both home gardeners and professional growers looking for a sustainable edge.

Each product is proudly made in Jersey using local materials, and now carries the Genuine Jersey mark—a symbol of authenticity, quality, and local craftsmanship.

We believe in transparency, sustainability, and supporting our local community. Whether you're a home gardener, a landscaper, or a retailer, we’re excited to share the benefits of our products with you.

We are proud to be working with SCOOP, a local champion of sustainable and ethical products. You can find our oyster shell soil improver and boost spray available in-store there.

At the moment we’re exploring the best next steps for expanding our retail presence across the island. If you’re a local shop or market interested in stocking our products, we’d love to hear from you!
