Optional Trellis Installation Instructions: The hooks of the long Trellis Support cords clip to the Metal Posts. Reach through and around the back Metal Posts and hook the clips from the outside in. Do the same with the other cord on the front. Then, hook the short Trellis Support cords on to and perpendicular to the long ones, at your desired spacing. TIP For plants that prefer crawling up, you may use your Trellis as a back wall, by attaching both long Trellis Support cords to the back Metal Frames on your Farm with the short Trellis Support cords as connectors in between.
