Here is a pic of the wall in question. Don't worry about the cracks. I already filled it in and am going to do the stairs when the weather gets drier outside. If you see the strip of soil that separates the retaining wall from the sidewalk that is where I want to plant climbing rose bushes. Due to limited space and for a simpler, cleaner appearance I was thinking of drilling some holes and then using rubber/plastic anchors to screw in some eye hooks. This was my idea instead of putting trellises in the ground. Then as the canes of the climbing rose bush grow I will use garden ties to bring them closer to the wall by tying them to the eye hooks.
My plans are as follow:
Repair cracks and broken stairs.
Apply a textured concrete coating to the entire facade to improve appearance.
Water-seal it to protect it.
Install a few eye hooks with appropriate anchors that aren't too big to support climbing rosebushes.
Also, to minimize the appearance of the eye hooks can I paint over them with the textured concrete coating so that the metal isn't visible? If not, can anyone recommend a suitable substitute? I've never used a textured concrete coating before but it appears that you just paint it on with a roller or a brush. I hope this makes our retaining wall look a lot better. That's an important part of my overall goal with this project.
Basically the look I'm going for is a climbing rosebush that looks like it's "hugging" the wall. This is the rosebush I am buying:
