John Innes Composts were originally developed at the John Innes Horticultural Institute in the 1930s. The four formulae were designed to cater for the different nutritional needs of plants ranging from seed sowing through to final containers. The range comprised Seed Compost and then numbers 1, 2 & 3, containing successively higher nutrient levels. SylvaGrow® John Innes Seed Compost, No.1, No.2 and No.3 offer gardeners an exceptional opportunity to use these great heritage composts with an updated peat-free formulation.
