Attach the trellises to the ground with stakes, sandbags or other heavy objects to keep them from blowing down in a storm (Image 1). At the end of the season you can just take them out, cut the zip ties on the top and move these trellis panels to another bed or even store them flat in the garage.
Add some vertical string supports to give plants some extra room to attach (Image 2). You can put several plants under each side, so four strings on each side should do. You can start by tying it off on the top support and wrapping it around each one below; then a quick knot around the bottom pip, and you're done.
Malabar spinach (Image 3), a vining plant whose tender stems and leaves are used in Asian and tropical cooking, especially stir-fries and salads, is an example of a plant that can be grown here. Like other leafy, dark-green vegetables, Malabar spinach contains many vitamins and nutrients that make it a great choice for health-conscious eaters.
