The present invention provides an automatic flower pot watering structure including a flower pot main body, a water storage tank, at least one supporting frame body and at least one water absorbing member. The flower pot main body is provided with a planting space. The water storage tank is arranged below the planting space of the flower pot main body. The at least one supporting frame body is installed inside the planting space of the flower pot main body and is provided with at least one raised portion and at least one threading portion corresponding to the raised portion. The at least one water absorbing member is a thread body which threads through and surrounds the eyelet portion of the supporting frame body, so as to form raising and the positioning effects. Moreover, at least one end of the water absorbing member goes through the bottom of the planting space of the flower pot main body to be immersed in the water inside the water storage tank, so that the water is absorbed from the water storing tank via capillarity to spread in the planting space. Thereby, the function of automatic watering is achieved.本發明一種花盆自動加水結構，包含：一花盆本體、一儲水槽、至少一支撐架體及至少一吸水件，該花盆本體具有一栽種空間，該儲水槽設置於該花盆本體之栽種空間下方，該至少一架體設置於該花盆本體之栽種空間內，設有至少一架高部及至少一對應該架高部之穿繩部，該至少一吸水件為繩體，穿繞於該架體之穿繩部，形成架高及定位作用，且該吸水件至少一端穿過該花盆本體栽種空間底部浸於該儲水槽的水中，透過毛細現象將水由儲水槽吸至栽種空間內擴散，達到自動加水的功能。
