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. |
