The present invention relates to a wall surface afforesting structure using carbonized cork having a novel structure capable of effectively afforesting a wall surface. The wall surface afforesting structure using carbonized cork, according to the present invention, comprises: a support panel (10), which is made of a carbonized cork material, is formed such that a plurality of coupling holes (11) to which flowerpots (1) are coupled penetrate the front and rear surfaces thereof, has, on an upper surface thereof, a reservoir groove (12) to which water is supplied, and has, on a rear side surface thereof, water supply grooves (13) connected to the reservoir groove (12) while vertically crossing the coupling holes (11) a blocking plate (20) coupled to the rear side surface of the support panel (10) so as to block a rear side surface of the coupling holes (11) and water supply members (30) which are inserted into the water supply grooves (13) of the support panel (10), and of which the upper ends extend to the inside of the reservoir groove (12) such that water supplied to the reservoir groove (12) is supplied to the flowerpots (1) coupled to the coupling holes (11), wherein protrusions (21) roundedly protruding to the front so as to correspond to the coupling holes (11) are formed on the front surface of the blocking plate (20), recessed grooves (3) corresponding to the protrusions (21) are formed on bottom surfaces of the flowerpots (1) and the recessed grooves (3) have water supply holes (4), and the water supply members (30) are made of a fiber material and are arranged so as to pass between the protrusions (21) and the water supply grooves (13), such that while water supplied to the reservoir groove (12) flows down to the lower side along the water supply members (30), water can be supplied to plants planted in the flowerpots (1) through the water supply holes (4) of the flowerpots (1) coupled to the coupling holes (11). Therefore, since water can be uniformly suppli
