PROBLEM TO BE SOLVED: To provide a greening device with bottom water supply which is easily settable on a horizontal surface and an inclined surface, and enabling water saving and equal water supply to a surface. SOLUTION: This greening device with bottom water supply includes laying on a set base, a water supply sheet which has flexibility and a double layer structure of an upper layer having a thickness of 1 mm or less a hydrophilic layer which enables capillary moisture transport, and of a lower layer of a low-pearmeable layer which has water repellency, and bringing the edges thereof into contact with a water supply source enabling water level setting in a plurality of individuals followed by soaking and setting a water negative pressure difference. As a result of this, using siphon effect and capillary moisture transport effect, it is possible to automatically adjust increase and decrease of a water supply requirement which is different according to season and vegetation for a medium or seed and seedling as a water supply object, and at the same time, to maintain a moisture condition which is uniform on a surface and favorable for growing.
