A trellis and trellis kit are provided with poles and lattice netting in which the lattice netting can be rolled up on the poles to which they are attached. Two crossbars are provided. They can be easily slipped on and off the poles to detach them from the netting, and the trellis can be formed into a compact package for shipping, warehousing, or storage by the user in a protected location. The poles preferably have square cross-sections. A pair of crossbars is provided with square holes slightly larger than the poles, so that the crossbars fit slidably onto the poles. The crossbars have very simple hook structures which engage the upper and lower edges of the netting to stretch it tight. Advantageously, the netting is made to bend across at least one edge of the crossbars, and at least one edge of each of the poles, so as to relieve strain on the fastening structures. The netting also can be rolled up on the poles to adjust the width and/or the tension on the netting, and the bottom crossbar can be moved slidably on the poles to adjust the tension and lattice dimension in the vertical direction.
