The stackable trellis support system of the present invention comprises a base trellis assembly and a main trellis assembly having a wire mesh frame assembly over which wire mesh is spread to support plant stems. The main trellis sub-assembly allows additional sections to be added to the existing stackable trellis support system, utilizing four common main post apparatuses for the connecting of each sub-assembly. In this regard, any number of individual main trellis sub-assemblies may be connected using the main and/or base post apparatus to form any number of patterns, depending on the desired use or available area.The base trellis assembly is anchored in and above the ground by stabilizing post anchoring rebar stakes upon which the base post apparatus rests. Further, the base post apparatus of the base trellis assembly has a locking bolt, which allows the height of base trellis assembly to be freely adjustable along the vertical axis of the base post apparatus and perpendicular to the ground.The netting is fabricated from strong weather-proofed steel stretched across and attached to the wire mesh frame assembly. Further, the weather-proofed trellis side panel may also be used for added horizontal support. As a result, the invention provides a simple to use, durable and adjustable garden support device which allows plants to grow upward, thereby maximizing available soil and ground space and providing ideal exposure to sunlight.
