  • Patent number: 5611172
    Abstract: An apparatus for the efficient treatment of a live plant is provided. In particular, the apparatus can be used to treat a live plant before being packaged in a sealed container in which the plant can live without any of the care or maintenance that live plants normally require. The apparatus comprises a substantially sealed pressure vessel, a vacuum system, and a root treatment system. The substantially sealed pressure vessel receives the container having the rooting medium and the roots of the live plant maintained therein. The container also has a runoff opening therein. The vacuum system, which is connected to the pressure vessel, draws air through the pressure vessel and live plant and thereby removes a predetermined amount of fluid from the rooting medium via the runoff opening. The root treatment system then adds a predetermined amount of a root treatment solution to the rooting medium.
