PROBLEM TO BE SOLVED: To provide a multilayered type water supply member for plants capable of installing the plants in a place such as a greening of the roof or a wall surface, etc., excellent in water holding and water flow properties and having flexibility. SOLUTION: This water supply member for the plants comprises a unit composed of several layers 8 prepared by laminating a water holding material 1 and a water-impermeable members 2 having water flow holes 6 arranged therein, having the surface layer which is the water-impermeable membrane 2 for penetrating roots of the plants contained in a container 3 having plasticity or flexibility and further a water supply part 4 and a drainage part 5 disposed in he container 3 in the Fig. The water holding material 1 may be composed of a clothlike material. When the several layers of the water-impermeable membrane 2 are superimposed, the opening diameter of the water flow holes may be increased in the surface part and that in the depth may be decreased. The number, size or distribution thereof can suitably be set.
