Match the structure to the purpose
A trellis for climbing jasmine, a living wall made of modular pockets and a timber privacy screen are different installations. One primarily supports growing plants, another depends on a managed irrigation medium, and another may be structural or decorative with no plants at all. We begin by deciding whether the goal is privacy, a softer boundary, productive planting or improved use of a small courtyard. Weight, exposure and maintenance requirements follow from that choice. A lightweight-looking green wall can become heavy when saturated with water.
