This simple corner trellis does double duty as both a sturdy support for your plants and a beautiful edible landscaping element in your yard. Use it to grow cucumbers, melons, peas, beans, or virtually any other vining plant. For best results, improve the soil around the base of the trellis before planting by mixing in Miracle-Gro® Garden Soil for Vegetables & Herbs with the existing soil. Also, feed plants with Miracle-Gro® Shake ‘n Feed® Tomato, Fruit & Vegetable Plant Food to ensure they have all the nutrition they need to thrive. Cut the lumber and lattice yourself, or have them pre-cut at your local home improvement store.

  • corner-trellis slide
    Use the Parts List and Cutting Diagrams as references for part dimensions. Cut the parts as needed for each step. Drill countersunk pilot holes for each screw except the ¾” lath screws; for those, drill non-countersunk pilot holes.
  • corner-trellis slide
    Apply solid stain to parts and assemblies as you build, and touch up as needed after the final assembly.
  • corner-trellis slide
    Position the post cleats as shown in Figure 1 (flush with one end and 1½“ from one corner) and attach to the post using 3" deck screws.
  • corner-trellis slide
    Drill a pilot hole in the end of the post where the post cleats are flush, and screw the finial in place as shown in Figure 2. Drill the pilot hole to match the diameter of the shank of the hanger bolt on the finial.
  • corner-trellis slide
    Use Figure 3 as a guide for cutting the long stiles (aka side posts).
  • corner-trellis slide
    Use Figure 4 as a guide for cutting the short stiles (aka side posts).
  • corner-trellis slide
    Use Figure 5 as a guide for cutting the upper and lower rail cleats. Cut the rail cleats from a long section of lumber, cutting from the end and moving right to left.
  • corner-trellis slide
    Position the upper and lower rail cleats as shown in Figure 6 and attach to the stiles using 3-inch screws.
  • corner-trellis slide
    Use Figure 7 as a guide for creating the bottom rail trim. The view in this figure is from an edge showing the 45-degree bevel cut on the ends.
  • corner-trellis slide
    Position the bottom rail trim on the bottom rail as shown in Figure 8 and attach using 1¼" screws.
  • corner-trellis slide
    Position the bottom rail trim/bottom rail assembly on the long stile and short stile as shown in Figure 9, and attach the bottom rail trim to the stiles using 1¼“ screws.
  • corner-trellis slide
    Use Figure 10 as a guide for creating the top rails.
  • corner-trellis slide
    Position the top rail as shown in Figure 11 (flush against the upper rail cleat andlower rail cleat) and attach to the stiles and cleats with the screws indicated at the specified positions.
  • corner-trellis slide
    Use a jigsaw to cut the lattice to the size indicated in the Parts List and Cutting Diagram, then position in place to check for size, and trim if needed. (Make sure the bottom rail is facing up). Attach to the stiles and rails using ¾" lath screws as shown in Figure 12. Repeat this process to create a second side assembly as a mirror image of the first assembly.
  • corner-trellis slide
    Position the first assembly on the post cleat as shown in Figure 13 and attach the long stile to the post cleat using 2½" screws.
  • corner-trellis slide
    Use a post-hole digger to create 6” deep holes positioned as shown in Figure 14. Insert the assembly into the holes as shown and temporarily brace or have a helper hold it in place until the next step.
  • corner-trellis slide
    Position the second assembly as shown in Figure 15 (set in place in the holes and flush with the top of the post cleat) and attach using 2½” screws. Touch up any marred or scratched areas with solid stain as needed.
