The present invention relates to a flowerpot having an automatic watering controlling function and, more specifically, to a flowerpot having an automatic watering controlling function, wherein the quantity of water supplied to the flowerpot is automatically adjusted using a buoyant member. The flowerpot having an automatic watering controlling function according to the present invention comprises: a plant accommodating unit having a space in which a plant is planted a water storing support coupled with the bottom of the plant accommodating unit and having an internal space a water-supplying container mounted on one side of the plant accommodating unit and a water-adjusting buoyant unit settled in the internal space of the water storing support and having a sealed internal space formed therein. A water-supplying hose extended from one side of the water-supplying container can be exposed to the top surface of the water-adjusting buoyant unit by penetrating though and extending from one side wall unit of the water-adjusting buoyant unit. Moreover, the flowerpot having an automatic watering controlling function according to the present invention can further comprise an elastic member having a particular thickness and formed on the top surface of the water-adjusting buoyant unit, wherein the water-supplying hose is exposed therethrough. When the flowerpot having an automatic watering controlling function according to the present invention is used, the following effects can be expected: first, water does not need to be supplied for a particular period of time after a particular quantity of water has been supplied, so that managing the flowerpot is very convenient and second, the discharging unit of the water-supplying hose can be automatically opened and closed using the principles of buoyancy - that is, the water-adjusting buoyant unit capable of automatically watering is used, so that the same can be semi-permanently used.COPYRIGHT KIPO 2015본 발명은 자동 급수 제어 기능을 갖춘 화분에 관한
