Besides the traditional, in-ground way to install a trellis, there are several other ways to use one, whether you're using it for edibles or aesthetics. A trellis can be placed into a single container. This idea can be expanded to include several containers, each with their own trellis. Alternatively, the series of containers can be joined by a single trellis, which spans them all. Hanging bags can also be used, each with a trellis installed. This adds stability for the plant and an instant barrier for your space. Upside-down vegetable planters can also benefit from the additional stability of a trellis.
