Crop-Specific Fertilisers

One blend per crop, each tuned to the real feeding pattern of its crop across the season — formulated to feed a single plant, brilliantly.

Crop-specific fertilisers

One blend per crop, done properly

Crop-specific organic fertilisers, each formulated for one job: to feed a specific crop, brilliantly. Instead of one balanced feed for everything, every blend is tuned to the real feeding pattern of its crop across the season. Each one is handcrafted in small batches at our Stockport workshop using organic ingredients. Insect frass is used in small amounts as a natural source of chitin and slow-release nitrogen, and multi-input formulations deliver complete nutrition in a single bag: N, P, K plus calcium, magnesium, sulphur and a full set of trace elements.

What's in the range

Why crop-specific feeding works

  • Tuned formulations: we don't sell one blend for everything. Each crop has its own formula matched to real-world feeding needs across the season.
  • Slow-release feeding: nutrients break down gently over the season, so there are no nutrient spikes, no root burn and no salt build-up.
  • Feeds the soil, not just the plant: organic ingredients support the bacteria, fungi and earthworms that build long-term fertility.
  • Compostable packaging: every blend in this range is supplied in compostable paper packaging.
  • Safe around children, pets, bees, birds and wildlife: no synthetic chemicals.
