How to Make Your Own Copper Pipe Garden Ornaments
Page 149 of the Trellis Craft book shows how to support trellises by using a concrete block and concrete. Here is a variation of that method.
Ordinarily, I would have pounded rebar a couple feet in the ground and used the rebar to support this trellis internally. But, I wanted to put this trellis where a tree had been, and there was a stump about a foot below ground which prevented pounding the rebar deep enough.
For this trellis, I put the actual trellis in the concrete. I could also have embedded rebar in the concrete, and then put the trellis over the rebar. See this page for a demonstration of that technique.
A gallon size or larger plastic jug. (The lower hole was taped over so concrete would not spill out.)

Ready to set out the cleaned trellis and support an overgrown Crossvine. One interesting thing about the spiral trellis is that it can support quite a long vine in a small vertical space. The Crossvine is about eight feet long. The copper tube that makes up the spiral in the trellis is ten feet long, so the trellis supports the vine with room to spare.
