Nursery Carolus is a trend setter concerning the nursery sector in the field of quality control. During the latest years, nursery Carolus has developed a packing system in cooperation with Universiteit Hasselt (University of Hasselt) and the IWT (Instituut voor de Aanmoediging van Innovatie door Wetenschap en Technologie in Vlaanderen). In this way we can deliver the tree without major destruction to the trees.
