I have pink jasmine (jasminum polyanthum) on a trellis which is attached to a block wall.

I want to train and help it to go further up my slope on the wall. I know Jasmine won't attach itself and that it needs help. Really don't want to drill holes in wall to use eye screws. I think I am going to use silicone to glue on the anchors, but I don't know the spaceing of them or the guage of the wire to use. Not looking for a pattern either.

Should I use more than 20 guage? Anybody used this product below?

Thanks for any help.
