Some of my garden hardware
I have a metal livestock fence panel -- a grid about 12 feet long and 5 feet tall. Recently, I've been growing cucumbers on it, but I've used it for pole beans in the past. I stand the panel up against three steel fence posts. I place a large stone under each end of the panel to lift it about 8 inches off the ground, and then I wire the panel to the posts. The space under the panel makes it easier to hoe or to mulch around the plants.
For the zucchinis, I use a long pallet that I picked up beside a dumpster some years ago. I lay it over the bed so the vines will grow up and lie on the pallet. My theory is that the zucchinis resist mildew and squash borers better with their vines off the ground. This method doesn't seem to deter the squash bugs, but they can be controlled somewhat by inspecting the leaves regularly and eliminating the eggs.
This year, I planted the tomatoes and peppers in groups of three. I gave each plant a cage and tied each group of cages to a steel fence post in their center. I do this because unsupported cages are likely to fall over in a rain or wind storm. The fence post eliminates this problem.
