Abstract: An expandable water trellis is provided including a plurality of hollow pipes of various lengths each having a pair of open ends and a plurality of linearly aligned water dispensers formed along a length thereof. Upon the flow of water within the pipe, water is dispensed through the dispensers for watering purposes. Also included is a plurality of caps each defined by a closed circular face with a periphery coupled thereto for defining an open top for removably securing about one of the open ends of one of the hollow pipes for selectively sealing the same. Next provided is a plurality of T-shaped interconnects each formed of a long tube with a pair of open ends and a short tube integrally coupled to a central extent of the long tube and extending perpendicularly therefrom thereby terminating in an open end which resides in fluidic communication with the open ends of the long tube.
