You can do either Copperdog
if mine, and considering appearance for the rest of the summer, I would keep only the healthy leaves and remove the rest. It may well mean every leaf. Then water. New leaves form fast. Then in a few weeks lift, "chop" or pull apart, pot up and water.
Heucheras get woody after a couple of years so digging up is good routine. Plus you have many more plants.
My own way is to have these replacement plants growing and available for a like for like swap.
