The enclosure is arranged to be filled with a plant growing medium, e.g., soil, to form the bed. Each of the members is an elongate hollow body having a pair of ends. At each end is a releasable connector portion which is arranged to releasably connect the members to one another at various angles to form enclosure of various shapes. Each of the members includes an inner wall having a plurality of small apertures which are in communication with the hollow interior of the member.
