Disclosed is a water-saving flowerpot for cultivating both soil and nutrient solution. The water-saving flowerpot according to the present invention comprises: a case member including an outer case, an inner case which is disposed apart from the outer case within the outer case, and of which an upper end is formed in an opened form such that crop can be planted in the inner case, and a connection panel which connects respective lower ends of the outer case and the inner case and forms liquid-receiving holes for receiving at least one liquid of water and the nutrient solution between the outer case and the inner case and a ventilation and liquid-supplying member including a partition panel which is disposed in the air at a predetermined height from the connection panel to divide a space between the outer case and the inner case into an upper space and a lower space, case-side ventilation protrusions which protrude upward from the partition panel to ventilate soil received in an upper part of the partition panel, and liquid-supplying protrusions which protrude downward from the partition panel to supply liquid received in the liquid-receiving holes to the soil received in the upper part of the partition panel such that at least some of the liquid-supplying protrusions are submerged into the liquid received in the liquid-receiving holes, and a portion of the soil received in the upper part of the partition panel is received in the liquid-supplying protrusions. The water-saving flowerpot has merits of enabling crop to be cultivated by a small amount of liquid even in a region where it is dry, or water is scarce. Moreover, the water-saving flowerpot enables high density culture and may not cause stress to be applied to crop roots. The water-saving flowerpot not only enables performing crop cultivation, but also can be used in crop cultivation for planting. The water-saving flowerpot may be used in the cultivation of both soil and nutrient solution. Further, the water-sav
