Use a cane or string to train the climber at first and it will then stay in position, permanently, when it grips the wall or the support wires or trellis that you provide on the wall.
I have a 6 foot wall that separates my back fence from the street I am looking to grow some climbing plants up the wall to cover it but the issue I have is at the base of the wall its very shallow until it hits cement. Therefore can you suggest any climbing plants that will grow in shallow depth ( 4 inches minimum) and if not climbing plants some other suggestions? The main issue is how shallow the depth is.
It sounds like you find the wall foundation close to the wall and 10cm deep. If you come out from the wall and dig down until you reach the extent of the foundation, you can plant any climber you like. Any climber can be trained along the ground and then up the wall.
