I am a basic skills diy'er, I'll give most things a go but happy to pay someone when it's out of my skill level.

This is our garden wall, it runs about 20m between our garden and next doors. Ground level is higher on our side.

I've attached photos of a section of the wall that is starting to collapse. Is this something that I can attach braces to or does it need more work? I'm not physically able to knock down/ rebuild but could drill and bolt on bracing myself.

Thanks for your help!
