Abstract: A collapsible and portable trellis which supports growing plants and increases their overall yield. The trellis includes a first half assembly, a second half assembly, and a locking mechanism. The first half assembly and the second half assembly are hingedly connected to each other through the locking mechanism and each includes a first lateral beam, a second lateral beam, a first crossbar, a second crossbar, a lattice, and an at least one support leg. The first lateral beam and the second lateral beam are positioned parallel and offset to each other. The first crossbar and the second crossbar are perpendicularly connected in between the first lateral beam and the second lateral beam to yield an overall rectangular shape. The support leg is connected to the second crossbar. The lattice is mounted to the first lateral beam, the second lateral beam, the first crossbar, and the second crossbar.
