PROBLEM TO BE SOLVED: To provide a wall surface greening system designed for wall surfaces of a house falling under the category of a building, using an extremely simple mechanism for distribution of pouring water so as to uniformly supply the water to the inside of the vertical surface based on the mechanism to result in reliable growth and increase of greening plants when greening the vertical walls of the houses. SOLUTION: The wall surface greening system has the following mechanism: distributing feed water from a plurality of longitudinally extending water supply pipes and a feed-water distribution means shorter than the length of each of a plurality of water holding tubs to the water holding tubs whose levels are maintained to be horizontal; and pouring water to planters from the water holding tubs via a water pouring means utilizing capillary phenomenon to pour the water so as to be uniformly dispersed under a compact structure.
