There is provided a column planter including a tank (2) to be filled with water, a plurality of planting pots (12) stackable on top of each other, to form at least one column of stacked pots (12), each pot (12) having a central opening (18) in its bottom, as well as a plurality of drainage holes (16), and a substantially vertical, substantially rigid tube (20) for each column on which tube (20), with their central openings (18), are strung the pots (12) of the column. The lower end of the tube (20) is supported in the tank (2) and the tube (20) is of such length as to at least protrude beyond the soil surface of the uppermost pot (12) in a column and an emitter (22) is attached to the upper end of the vertical tube (20). There are further provided mounting and supporting members for affixing the column of pots (12) on the tank (2), and a pump (26) having an inlet and an outlet opening and adapted to draw water from the tank (2). The outlet opening is operatively connected to the lower end of the vertical tube (20) into which the pump (26) forces the water drawn from the tank (2), to be issued from the emitter (22) at the upper end of the tube (20), wherein water issued from the emitter (22) trickles down, passing from one pot (12) into another pot (12) therebelow through the drainage holes (16), and returns to the tank (2) to be recirculated by the pump (26).
