John Innes Compost

Built on the trusted John Innes compost formula and supercharged with organic worm castings, our John Innes wormcast and traditional range features formulas suited to each stage of a plant’s lifecycle. The worm casts bring an organic, 6-week slow-release feed rich in essential nutrients, and are delivered in their most easily absorbed form, alongside billions of beneficial microbes that get to work rebuilding soil structure from the moment you pot up. 

The light, open texture encourages roots to spread freely, and the nutrient content, pH level, and speed of nutrient delivery is tailored to each plant depending on the type of compost. 

Our traditional John Innes compost range features the tried and tested loam-based formula. With versions available for seeds, rooting cuttings, potting-up and supporting mature, well-established plants of all types and sizes. The nutrient content, and pH level, of each compost in the range is carefully tailored according to the unique demands at every stage of the plant lifecycle.
