Root preservation - help!

[PowerPlayed]

I have a very high (approx 20ft) wall at the back of my garden covered in ivy and another unifentified climber.

Approaching the wall was a bank which I have had to have dug out to a distance of 1metre from the wall. In doing so some of the roots have been destroyed/ dug up
and the cut ends are exposed. I want to give the climbers the best possible chance of surviving - is there anything I can do to encourage regrowth/keep plants from dying?

do not worry about the ivy
its a bugger to kill

what is the other climber ?

I'm not sure what the other climber is - there are two pics attached one was covered in tiny white flowers until a week or so ago.

THat looks like a climbing hydrangea
again, should be just fine
lovely plant

Thanks @Ta1kinpeace

They are lovely and they cover a wall that would put the GoT wall to shame it's that big!

If you want some fun, run a passion vine up through it - then in the summer you'll get flowers and pretty (but non edible) fruit)

If it gets carried away you can cut it hard back.

Oh that looks good - I've just removed a huge conifer from the back corner and want to grow something up the bare block work which will provide quick coverage.
