Abstract: A trellis apparatus for supporting a growing plant includes a mesh operable to support and hold a growing portion of a plant when the plant is held by a portable container, and a frame operable to support and hold the mesh above the plant when the plant is held by the portable container. The mesh is sized and configured to not support and not hold a growing portion of another plant when the other plant is not held by the portable container. The mesh includes an array of passages, each passage defined by a section of a line that is configured to form the mesh, and at least one of the passages is sized to allow a growing portion of the plant held by the portable container to extend through the passage. The frame includes a stanchion operable to position and hold the mesh above the plant when the plant is held by the portable container, and a coupler operable to secure the stanchion to the container that holds the growing plant.
