How to set up support wires on a stucco surface?
The front walls of my house has stucco, I don't know how to prepare it for vines to climb. If I use some C-hook screws do I need to make a pilot hole first? The stucco seems to shed when I run my hand against it, so I'm not sure what's underneath it, seems pretty fragile. Is there mortar under the stucco? I've drilled into bricks, paver stone, wood, metal,.. but never stucco. Also, what type of wire should I use? Metal, plastic, nylon (fishing line)? And how should I hang the wires? In squares, or diagonals, which arrangement is best for vines?
