Seed and potting composts and other growing media
Introduction
An organic growing medium - seed, potting, or multipurpose compost - has, as its main ingredient, biologically active material, such as composted plant wastes. Seed compost should be low in nutrients. Other mixes should provide plants with nutrients for as long as possible, to limit the need for liquid feeding.
