Upright planting apparatus

An upright planting apparatus comprising:

• a row of juxtaposed mesh pipe units each configured to extend in an upright direction, and including an outer mesh pipe, and a liquid supply pipe, said outer mesh pipe having an upright tubular wall that is formed with a plurality of mesh holes extending through inner and outer surfaces of said upright tubular wall, and a groove that extends around said outer surface of said upright tubular wall and that communicates fluidly with an interior of said upright tubular wall through said mesh holes, said liquid supply pipe being disposed axially inside said outer mesh pipe and having a plurality of liquid-seeping holes;
• and
• a fixing unit including:
• a fixation frame disposed at a rear side of said mesh pipe units and elongated in a longitudinal direction which is transverse to the upright direction;
• and
• a positioning member which has an elongated segment that defines a lengthwise line, and which is coupled with said fixation frame to render the lengthwise line to be oriented in the longitudinal direction when said positioning member is placed in a locking position such that in the locking position, said mesh pipe units are brought into side-by-side contact with each other.
