An expandable pot for containing the roots of a plant is designed to expand primarily in response to the growth of the plant's roots. The sides of the pot are folded in an accordian-like manner which flexes outwardly to increase the volume of the pot in response to the growth of the roots therein. As the pot expands outwardly, additional soil is added into the pot in order to maintain the surface of the soil at a desired level. Formed beneath the expandable pot is a drain container and formed along the sides of the pot is a stop member for limiting the expansion of the pot to a predetermined volume.
