Each Expandable Pea Trellis has eight hinged panels with big 20cm (8") grids. Simply zig-zag the panels through your row of peas and push them into the ground (add a stake on each end in windy locations). Total size 2.95m wide by 1.52m tall (116" x 60") installed. Trellises fold for easy off-season storage and reduced shipping costs. Reusable year after year, and they can also support sweet peas, cucumbers, and any other vines. A really stable structure like the Expandable Pea Trellis will give you stronger plants and more productive pea vines. The powder coated green steel wire construction is unobtrusive in the garden and practically invisible once the plants grow in.
