This is an idea that I saw on Facebook last year -- it was on the Botanical Interests Seed Packets page (which is a pretty interesting page, with lots of intriguing ideas, if you "do" Facebook).
I used a hoop house frame that I had purchased on ebay a couple of years back (the cover that came with the frame had deteriorated after one summer), and covered it with "remesh" (welded wire mesh for reinforcing concrete). I've planted cucumbers, gourds, mini pumpkins and acorn squash on either side, with some onion plants on the inside. So far this is where it's at --
Stayed tuned for future developments!
