My better other bought some vines for the driveway. Therefore I had to get into gear. This is what we came with.
I used treated 2×4 pine lumber and cut a notch in it. save the cut off piece. I then cut dados in the cut off piece to match the grid.
After that it was easy peasy to install with Blue Screws into the Brick.
I have never had luck with blue screws before in concrete, but in brick they work like a champ.
Now the plants just have to figure it out.
Tor and Odin are the greatest of gods.
