PURPOSE: A vegetation box assembly is provided to prevent water from being stagnant in the soil and plants accepted to the vegetation box by improving a water supply system and to supply flowing moisture by a Siphon method. CONSTITUTION: The vegetation box is attachably and detachably combined in a hanger member fixed to the wall by intermediation of a fixing means. A water supply part is arranged to the upper of the vegetation box, and supplies water. In order to be provided with the water from the water supply part, one end is penetrated into one side of the vegetation box and arranged at outside. The other end part(520) is divided into a plurality of parts and is divided about the vegetation box. In the water supply cloth, the other end part partitioned into a plurality of parts is penetrated into the other side of the vegetation box, and the end of the other end part of the water supply cloth is connected with one end of the other water supply cloth located in the lower part of the vegetation box. A water tank &lsqb；water tank&rsqb；(200) is accepted to contain a water supply member to transfer moisture to one end side of the water supply cloth inside. The water is saved. The fixing means includes a fixing bracket(20), in which one end is fixed to the hanger member by intermediation of a connecting member including bolts or screws etc., and the other end is slopingly bent and is hung and combined in a rear side by a connection hole(130). The vegetation box is a box shape, in which a space part accepts internally accepted soil and plants and an opening part is formed to expose the soil and the plants at front. The vegetation boxes form a penetration hole, in which each water supply cloth(500) can be penetrated into one side and the other side. A water collecting tank(300) is formed with an open side to collect water through the other end part of the water supply cloth. The moisture is supplied through the water supply cloth to the soil within each vegetation box a
