A challenge in pot culture technology is to find sources of cheap, but superior quality substrates. The high prices of substrates increase the production costs of the final product and make it less affordable to consumers. Furthermore, the increasing restrictions on peat exploitation in European countries have necessitated research into finding alternative organic materials as suitable substrates. This study aimed to investigate the effect of grape marc compost as an alternative composite for potted culture of four woody ornamental species and cultivars. For this, the marc grape compost was mixed with leaf compost, forestry compost and peat. Starting only in the second year of cultivation, plants were fertilized with a Coïc solution during the vegetative growth phase. The mineral content of the substrate as well as the growth response of the plants to fertilization were reported.
