Abstract: The invention relates to a plant tray for holding and supporting potted plants. The invention includes a spacer support rack and at least one riser with a ring at its topmost surface. Within the ring is a plurality of tabs for supporting plant pots of different sizes. The spacer support rack is configured to allow equal spacing between the plants when placed in the plant tray. This allows for optimization of the health of the plant and the space available to the grower. The spacer support rack is constructed in a manner that multiple plant trays can be nested on top of each other, allowing them to be stored in a directly vertical arrangement maximizing the use of the storage space available.
