  • Patent number: 5673511
    Abstract: A self-watering tray for supporting and displaying a plurality of potted plants which can be watered from a water reservoir in the bottom of the tray, the tray comprising a plurality of wall sections which define spaced openings in the tray, each wall section being provided with a support located above the reservoir for supporting the potted plant at or above the water, and being laterally open to the adjacent wall sections below the supports to provide a continuous reservoir channel below the supports and pots, through which water can circulate for watering plants by capillary action.

  • Patent number: 5427240
    Abstract: A shipping box for plants set with soil in pots, in which a plurality of holder panels are positioned in the box in spaced relation. Each panel is formed with a plurality of pairs of entry slots extending vertically upwardly from the bottom of the panel. The entry slots terminate at their upper ends in retaining slots adapted to receive elastic, resilient retainer bands which when expanded are adapted to extend around and thus constrict a potted plant and resiliently bias the plant toward the panel. The plant is thus retained in position during shipping, and its spilling of soil is prevented in the event the box is tipped or tilted.

  • Patent number: 5282335
    Abstract: A self-watering dish garden includes a lower container section which defines a liquid holding reservoir, an upper container section which fits on the lower container section and has an open top, and a tray which fits into the upper container section. The tray receives plant material in a growing medium and has a depth such that the bottom of the tray is above the top of the lower container section. The tray includes a supporting flange for supporting a partition which includes an outer rim and retaining members. At least one water absorbing member extends from the growing medium through the bottom of the tray into the liquid holding reservoir.

  • Patent number: 5193305
    Abstract: A self-locking insertion device for a water-transmitting wick for a potted plant adapted to be watered by the wick through capillary action from a water supply, the device including a generally flat, elongated, transversely flexible and resilient main body portion having opposed walls and formed at its upper end with a slot for frictionally retaining the wick which extends therefrom into growing media in the pot. The device further includes a flexible, resilient base portion integrally formed with said main body portion and having a lateral dimension greater than a bottom opening in the pot and generally flat top flanges adapted to engage the bottom surface of the bottom wall of the pot around the opening in the pot when the device is mounted. The base is formed with an enlarged opening to receive the wick and a narrow slot extending from the opening to the exterior of the base at the bottom thereof and through which the wick can be inserted toward the opening.
