Specifies physical, chemical, biological and labelling requirements for potting mixes packaged for retail sale. Includes requirements for regular and premium grade mixes as well as special purpose mixes.

This Standard specifies physical, chemical, biological and labelling requirements for potting mixes packaged for retail sale. Potting mixes of both regular and premium quality are covered. Requirements are also included for mixes labelled as suitable for African violets, bulbs, hanging baskets, seedlings, orchids, acid-loving plants and plants that are sensitive to phosphorus.Test methods for the analysis of potting mixes are set out in Appendices A to G.NOTE: Appendix H gives guidance on the determination of compliance with this Standard.
