I have a wisteria plant that I would like to train into long, horizontal branches. It's growing against a cinder block wall. I tried screwing some masonry screws into it, but those just ground a hole in the wall that was too big for the screw to then grab anything.
How can I attach things to cinder block walls? Do I need to use some kind of epoxy instead of screws? And then what kind of anchor/device should I then attach that will be good for supporting the wisteria branches?
