The invention relates to a stackable carrier for growing material, such as pot plants, cuttings and plants placed in trays, comprising a substantially rectangular flat plate (35); and supports (36) extending transversely of the plate from the short sides of the plate for the purpose of supporting the carrier in a stack of carriers. This measure results in simplified handling of the carriers with the plants placed thereon. The carriers with the plants can be easily stacked on top of one another from above, wherein this is avoided in horizontal direction between the vertical posts of the Danish trolleys. Such operations therefore entail less effort. The invention furthermore provides the option of the grower using the carriers for his internal transport and even as carrier for the plants on the seedbeds. The supports preferably extend upward from the plate and the carrier comprises a frame extending at least at the periphery and a plate placed separately inside the frame.
