round up plant damage

[lukemelo216]

Picked up a new commercial account a few days ago becasue of neglegence by the old contractor. Their guys let the weeds get out of control in the beds, then sprayed them all with round up. Well sure enough some of the plants got hit with round up and are now showing signs of damage becasue of poor spraying and the contractor got terminated. ITs mainly to some junipers (either buffalo or kalley not 100% sure) anyways they are brown and red from the damage.

I have never delt with pesticides damage such as this so I do not know how we should go about caring for these plants. Should we just prune off the dead material or hit them with some fert or what? I just dont want to do something to these plants and hurt them further.

Any help is appreciated.
