CD, We were going to build all of the trellises using copper pipe. We made two and they are beautiful! But with all the gardens it was getting too expensive so we pulled them and decided to go with PVC and used the copper ones in our front yard until last fall when we were redoing some of our outside plans. now they are just pulled up waiting for a new home this spring.
The beans have not had a problem growing on them but the peas needed string or netting to hold onto.



Here is the picture of the two copper trellises. I am sure I will find a good home in one or two of my gardens this spring for these beauties.
