Abstract
Abstract A self-watering plant pot or receptacle comprises a reservoir for water or the like and a container for soil or the like and plants therein, which is located substantially entirely above the water surface. At least one tube extends through the soil in direct engagement therewith and has its lower end projecting into the reservoir for the supply of water to the reservoir. A liquid absorbent and transporting hose or sock, which may be comprised of textile or synthetic fibre material, is drawn upon the outside of the liquid supply tube for transferring water from the reservoir to the soil in the container.
