If you are lucky (or unlucky) enough to have or have access to a bamboo grove and can harvest a few trees, then you can easily make a trellis for plants. I have some maypop plants which need some support, so I got a few sticks of bamboo and made a trellis. I constructed mine in place. I stuck three pieces in the ground about one foot apart. I hammered them in so that they were secure. Next I wove in shorter cross pieces. The green bamboo was easy to work. The cross pieces were made of 1/2" diameter pieces and smaller. Although there was good tension due to the weave, I tied each joint with green plant string. The finished product had a sort of oriental look which I like.
