Environmental Mix

Support sustainable farming and boost on‑farm biodiversity with our specialist environmental crop seed range. Designed for countryside stewardship and SFI goals, our mixes help create healthier, more resilient landscapes while enhancing the long‑term performance of your farm.

Our wildflower seed mixes and bird‑friendly habitat blends attract pollinators, increase beneficial insect activity, and provide vital food sources for farmland birds. For productive yet regenerative forage, our herbal leys enrich soil structure, improve nutrient cycling, and deliver high‑quality grazing that aligns perfectly with modern environmental schemes.

Together, these environmental crops build a more balanced, diverse, and sustainable rural environment — supporting both wildlife and profitable farming systems.
