A self-watering plant pot includes a lower shell, an upper shell, a dehumidifying module and a water-guiding component. A first accommodating space and a second accommodating space are respectively formed inside the lower shell and the upper shell. The upper shell is detachably installed on the lower shell to form a discharging structure cooperatively with the lower shell. An intake structure is formed on the lower shell. The dehumidifying module drives air to flow from an external environment into the first accommodating space via the intake structure and then flow to the external environment via the discharging structure and further for condensing moisture of the air flowing into the first accommodating space to liquid water. The water-guiding component introduces the liquid water from the first accommodating space to the second accommodating space to provide the liquid water for plants in the second accommodating space.一種自動澆水植物盆器，其包含有一下殼體、一上殼體、一除濕模組及一導水件，該下殼體與該上殼體內分別形成有一第一容置空間與一第二容置空間，該上殼體係可拆卸地安裝於該下殼體上以共同形成一排氣結構，該下殼體上形成有一進氣結構，該除濕模組係用以帶動空氣由外界經該進氣結構進入該第一容置空間再經該排氣結構至外界且另用以將進入該第一容置空間之空氣中的水氣凝結為液態水，該導水件係用以將液態水由該第一容置空間導引至該第二容置空間，藉以提供水分予栽種於該第二容置空間中之植物。
