  • Patent number: 4052818
    Abstract: Plants are containerized with a self-watering system by forming a water reservoir in the bottom of a container with a screen supported over the reservoir spaced from the water by means of a coarse growing medium received in the reservoir. Above the screen is a fine growing medium which, prior to initial introduction in the container, is prevented from dropping through the screen by means of a permeable easily decomposable sheet material such as filter paper placed over the screen. The roots of the plant are placed in the fine growing medium, however, due to the size of the mesh of the screen, specialized or water roots are developed which extend through the screen and into the reservoir to help feed the plant with water. The fine growing medium receives its water from the reservoir through means of one or more wicks which extend between the reservoir and the fine growing medium above the reservoir.
