Yes, you will want to clean up the planting site and prepare the soil for the new planting.
Turning the soil and raking up the old roots and dead plant material will take a bit of time but worth the effort to ensure the success and health of the new plugs going in.
For your information I'm including a link about the residue and after effects of herbicide in the soil.
