The production of pot plants has increased in recent years. The expansion is partially due to the development of growth techniques. This development and the increase of production intensity has set new demands on growing media, as well. The welfare of the plants is largely based on the welfare of the roots. Sufficient amounts of water, oxygen and nutrients must be available for the roots in the substrate. There is a wide range of suitable materials for growing media, used either as such or as mixtures.

Several factors influence on the choice of the substrate for certain plant types. Together with the basic biological needs of the plant, technical growth factors are of great importance when choosing a growing medium for pot plants. Furthermore, other factors which are of great significance are discussed. Peat with limestone and fertilizers alone or mixed with additional materials is a high-class substrate for modern pot plant nurseries.
