After lots of conversation and research on vines, we decided to go with teardrop ivy. There are so many vines that can be trained this way, but for our space/lighting/zone, etc. this seemed to be the way to go.
We went with a "two x" pattern. Mr. screwed three screws across the bottom and three across the top, equidistant from each other.
We happened to have copper wire on hand for the trellis.
It was super bendable and easy enough to twist around the screws to secure it into place.
We looked for plants that had long tendrils to get a jump start on the training process.
I will be sure to post more pictures once our espalier is established. Fingers crossed it grows fast!
This girl was itching to get in the garden and help which is a no-no ;). #bullinachinashop
