Abstract
A container for rooted plants, seeds, seedlings or bulbs, made of corrosion resistant material, provided with a plurality of openings in its wall surfaces, open at the top. The size of the container and the wall openings is designed to permit nutrition of the plant from within and without the container when this is filled with a nutrient medium and set in an environment of nutrient medium. The girdling of roots is prevented. The size of the container and the wall openings are sufficiently small and rigid to prevent the plant from developing a root system that would permit the plant to grow beyond dwarfed size and to prevent an appreciable proportion of the roots from penetrating the walls. A method for growing dwarfed plants employing the container is described.
Claims17
A plant container comprising a receptacle having an upwardly facing opening formed from a corrosion resistant material and having holes formed therethrough, said holes having a width of approximately 0.05 mm to about 0.3 mm, said receptacle being adapted to contain a nutrient medium and the root portion of a plant and adapted to be placed in a pot containing a nutrient medium, said receptacle being sized so that its volume cannot contain a sufficient amount of nutrient necessary for normal growth of a plant growing therein, said receptacle having a sufficient number of holes therethrough to allow the plant roots in said receptable to draw sufficient nutrients from outside said receptacle to nourish said plant.
A plant cultivation system comprising a first receptacle having an upwardly facing opening formed from a corrosion resistant material and having holes formed therethrough, said holes having a width of approximately 0.05 mm to about 0.3 mm, said first receptacle having a nutrient medium and the root portion of a plant therein, a second receptacle larger than said first receptacle and containing a nutrient medium, said first receptacle being placed in said second receptacle, said first receptacle being sized so that its volume cannot contain a sufficient amount of nutrient necessary for normal growth of a plant growing therein, said first receptacle having a sufficient number of holes therethrough to allow the plant roots in said first receptacle to draw sufficient nutrients from the nutrient medium in said second receptacle to nourish said plant.
A method of growing dwarfed plants comprising the steps of providing a receptacle formed of corrosion resistant material having an open top and holes therethrough of a width of from about 0.05 mm to about 0.3 mm, placing a first nutrient medium in said receptacle and a plant propagating material in said first nutrient medium, and placing said receptacle in a pot containing a second nutrient medium, whereupon the growth of the plant resulting from said plant propagating material is dwarfed by the major portion of the roots of said plant being confined within said receptacle wall.
