ABSTRACT:
The present invention provides a plant growing unit which is generally flexible and comprises upper and lower compartments formed of flexible polyethylene or other plastics materials. The flexible upper compartment constitutes a plant root-ball container open for upward growth of a plant when placed in the container, while the flexible lower compartment constitutes a reservoir for water optionally containing added fertilizer nutrients or other dissolved materials. Level restricting means, such as at least one aperture in the walls of the lower compartment, is provided for establishing a maximum level of water in the reservoir which in use of the unit results in an air space between the water level and the root-ball of a plant when in the container. The unit also has one or more openings between the upper and lower compartments allowing root growth from the container to the reservoir.
