摘要: A root-level plant watering and feeding device has a hollow annular liquid dispersion member that circumscribes center opening of sufficient size to completely encircle buried root system an elongate tubular fill tube connected with the which upper portion extending upwardly therefrom terminating in open top end. removable cap encloses The lower row longitudinally spaced perforations through its side wall face toward opening. is positioned underground substantially horizontal plane encircling radially relation end disposed above ground surface. Liquids nutrients introduced into are disbursed generally equally soil holes directing or below system. When empty removed, serves as aerator conduit deliver oxygen directly surrounding roots.
