The present invention relates to a wall greening and planting system which comprises: a frame mounted vertically or slopingly； a water storage housing plurally mounted to be vertically arranged on the frame or bilaterally and vertically arranged, and having a water storage space formed on the inner side and opened to the upper part, an overflow part formed in the water storage space to discharge water which rises to a fixed level or higher to the lower side, and at least one pot coupling part with an opened upper end formed to provide a passage connected to the water storage space； and a planting pot which is inserted into the pot coupling part to be detachable, has a water supply port formed on the lower part to receive water from the water storage tank, and provides a space for planting. The water storage space is filled with a fixed quantity of the water supplied from the water storage housing, and the water is discharged to the lower part by the overflow part. Accordingly, the water is allowed to be supplied to a water storage space of another water storage housing placed on the lower side of the former water storage housing by gravity. According to the present invention, the system is easily assembled and installed and conveniently maintained, and costs required for construction and maintenance can be reduced so the system is economical. Furthermore, a water supply structure can be simply formed, and water supply is efficiently performed. The arrangement of plants is free, and the efficiency of the arrangement and the landscape are excellent.본 발명은 수직 또는 경사지게 설치되는 프레임； 상기 프레임에 상하로 배열되거나, 좌우 및 상하로 배열되도록 다수로 설치되고, 상방으로 개방되는 저수공간이 내측에 형성되며, 상기 저수공간 내에 일정 수위 이상의 물을 하측으로 배출시키는 오버플로우부가 마련되고, 상단이 개방되는 포트결합부가 상기 저수공간에 연결되는 통로를 제공하도록 적어도 하나 이상 형성되는 저수하우징； 및 상기 포트결합부의 내측에 착탈 가능하게 끼워지고, 상기 저수공간으로부터 물이 공급되도록 급수구가 하부에 형성되며, 식재를 위한 공간을 제공하는 식재포트；를 포함하고, 상기 저수하우징으로부터 공급되는 물이 상기 저수공간에 일정량 채워진 상태에서 상기 오버플로우부에 의해 하방으로 배출됨으로써, 중력에 의해 그 하측에 위치하는 다른 저수하우징의 저수공간으로 공급되도록 하는 벽면 녹화 식재 시
