Southern Trident – Driving Sustainable Growing for 2025 and Beyond
Southern Trident is a leading manufacturer of high-quality, award-winning, peat-free composts and other growing media, proudly developed under our trusted brands Coco & Coir, Little Big Compost, Harmony Gardens, Little Big Compost, and now the exciting new launch of Gromeo – our fun, innovative grow-your-own brand designed to inspire the next generation of sustainable gardeners.
Little Big Compost offers a full range of lightweight, easy-to-carry compressed coir bricks, bagged composts and mulches, plus coir-based pots, basket liners and accessories. Our Houseplant Compost was recognised as DIY Week’s Garden Product of the Year 2023.
Harmony Gardens, the world’s only carbon-neutral peat-free compost, continues to set the benchmark for responsible growing. With tried, tested, and proven formulations, the range has won multiple industry accolades including Best New Growing Media Product and the Sustainability Award at Glee 2021, and Best Retail Garden Product at Four Oaks 2022.
Little Big Compost, our consumer-friendly compost range, has achieved the prestigious Which? Best Buy award for its All-Purpose Compost for two consecutive years – a rare recognition that highlights both quality and consistency.
Gromeo, our newest brand for 2025, takes sustainability to another level – bringing high-quality, grow-your-own kits to market with an engaging, family-friendly style. More than just products, Gromeo represents a movement towards making sustainable gardening fun, accessible, and larger than life.
All products in the Southern Trident portfolio are made exclusively from environmentally responsible by-products and recycled raw materials. We are carbon neutral across all operations, Soil Association accredited for coir supply, and an inaugural member of the Responsible Sourcing Scheme for Growing Media (RSSGM). Southern Trident has also been recognised with an International Green Apple Environment Award and honoured as a Green World Ambassador.
At GLEE 2025, we’re excited to showcase brand-new launches across all ranges, including the full debut of Gromeo. Visit us at Stand 9E83 to experience the future of sustainable growing first-hand.
