A plant container includes a container body and an automate watering arrangement, wherein the automate watering arrangement includes a reserve unit and a plurality of watering units. Each of the watering units includes a guiding element and a watering element, wherein one end of the guiding element is communicated with the reserve unit, and another end of the guiding element is coupled with the watering element end-to-end. The watering element is downwardly extended from the guiding element and submerged into the soil of the planting cavity such that the water of the reserve unit is guided to flow to the soil of the planting cavity via the watering element so as to maintain a moisture level of the soil for the plant.
