The invention relates to a plant wall (1 ), comprising a plurality of stackable, elongated container elements (3), whereby inside each container element (3) can be accommodated at least one plant for growing. In the plant wall (1 ), the roots of each plant set for growing are introducible inside a non woven bag (4) provided with small perforations, said bag having been manufactured from a porous plastic-based nonwoven fabric material which transmits both water and nutrients possibly dissolved in water, yet does not itself substantially absorb water, whereby each non woven bag (4) is capable of being positioned inside a container element (3) in such a way that the stem of each plant accommo¬ dated in the non woven bag for growing extends upward from a floor (35) of said container element.
