Abstract: A method for producing a ready-to-plant live fence unit includes providing an elongated container containing a growing medium, planting within the container at least two plants, and cultivating the plants to grow in an interlocked manner to a substantially uniform approximate desired height so as to form a ready-to-plant live fence unit. Preferably, the cultivation includes treating the plants with a chemical pruning agent so as to limit their vertical growth to the approximate desired height. The method also preferably includes providing a vertical trellis adjacent to the container, and treating the plants with a growth regulator which accelerates growth. In an alternative implementation, the live fence unit may be produced even from a single plant cultivated asymmetrically to have a length which is at least about three times its width.
