Abstract
A plant root growth training device in the form of a plant pot, particularly suited to the early development of juvenile trees or shrubs. The pot is designed so as to have four hollow legs 11, 12, 13 and 14 which define generally pyramid shaped root growth passages to confine lower root growth to four separate regions of the pot. The pot includes upstanding root growth training means in the form of ridges 15 disposed inside the pot about midposition so that a plant planted generally centrally within the pot will have its root growth influenced to form a root structure having clumps of roots. These clumps are confined to the legs 11, 12, 13 and 14 so that on removal of the juvenile plant from the pot 10, the root structure of the plant will have a divergent root pattern.
Claims4
A plant root growth training device comprising an open topped container having a bottom wall including water drainage openings and a peripheral wall having an upper peripheral edge, said peripheral wall extending from the bottom wall of the container to the upper peripheral edge and defining a longitudinal passageway extending from the upper peripheral edge and terminating at said water drainage openings in said bottom wall, said passageway including an upper main passageway and a plurality of lower branches, said main passageway having a lower end located in said container between said upper peripheral edge and said bottom wall and said branches extending from the lower end of the main passageway to adjacent the bottom wall of the container, said branches defining a plurality of separate angularly spaced longitudinally extending outwardly tapering passageways, each tapering passageway being defined by the peripheral wall of the container and a pair of v-shaped outwardly diverging walls, with the walls of adjacent tapering passageways intersecting and terminating in angularly spaced radially extending ridges located adjacent the lower end of the main passageway, the ridges and said v-shaped outwardly diverging walls of the tapering passageways providing a plurality of radially extending ridges adjacent the lower end of the main passageway alternating with longitudinally and radially extending valleys terminating adjacent the bottom of the container.
