ABSTRACT:
Prior to planting, a disc or plate is installed in the bottom of a container. The disc is porous or has a series of slits in various patterns to permit the disc to be trimmed to proper size to fit various sizes and shapes of containers, preferably with an upward curl near the sides. Shallow grooves in the top surface facilitate bending the curl. The slits also permit drainage of water without permitting dirt to enter the space below the disc. Slits in the bottom supplement the top slits and facilitate trimming and drainage. The bottom of the disc has legs which space the disc above the bottom of the container. At different spacings from the center are shallow cups having detachable bottoms. When the disc is in place, a tube is pushed through the outermost cup, pushing out the bottom so that the bottom end of the tube extends into the space below the disc. The top of the tube is cut off slightly above the surface of the soil in the container. In use, the plant in the container is watered until some water collects in the bottom space. Drainage is permitted for a sufficient time period. Excess water is removed by means of a squeeze bulb inserted in the top of the tube.
