An automatic plant watering and feeding system includes a plant vessel supporting a quantity of soil and an underlying water reservoir in communication with the soil by a porous wick. The water reservoir is divided into four chambers. In one chamber a float mechanism controls an input water supply valve while in a second chamber a float mechanism controls the air venting of the first chamber. The third chamber is communicated with the soil by the porous wick and the fourth chamber utilizes a dual interlocking float mechanism to dispense a measured quantity of liquid plant food into the system reservoir during a replenishing cycle.
