A plant cultivating container comprising a hollow cell (10) for holding a growing medium and a plant. The cell has side walls (11), a base (20) and an open top (12). Air vents (30) are disposed on the side walls of the container. The base is vertically-movable base with guide tabs (21) which are extendable though an air vent. When the vertically-movable base is pushed upwards to eject the cultivated plant, the vertical movement is guided by engagement of the tabs within the air vents resulting in uniform support at all sides of the base. This enables the removal of the growing medium and the plant cultivated within it, in a substantially compact unit resulting in minimized root damage and transplant shock to the cultivated plant. The air vents of the plant cultivating container further comprises retaining flaps (31) to aid in the pruning of the roots.
