The vertical supports poles are made of 1” diameter steel electrical conduit. This stuff is pretty cheap and lasts forever. Make the lengths about 2’ longer than the height of the mesh. You can paint them as well if you want to, but I didn’t bother.
When the paint on the mesh has dried, alternately bend the horizontal wires on the ends in and out. This lets the vertical support poles slide into the mesh.
The cucumber trellis is ready to use. Just pound the stakes into the ground and you are ready to go. Pull the stakes out at the end of the season. I don’t bother to even remove the stakes from the web. I just lean the whole thing up against a wall in my shed for the winter.
These supports will easily handle the most fruit laden cucumber vines.They are easy to build and I expect will last a lifetime. The fruits are clean, have no yellow spots, and are easy to pick. According to a study by North Carolina State University, cucumber plants grown on a trellis are 2-3 times more productive than those grown on the ground.
You can also make lighter weight versions of this. I have a couple made from garden fencing that was left over from rabbit proofing the vegetable garden. It has openings about 2" X 2". Tomato stakes are used instead of conduit for the poles. It is not strong enough for melons and larger cucumbers, but is great for peas and pickling cucumbers.
