Pruning Heuchera 'Melting Fire'

Hello all

I Hope you are Well.

I have some Heuchera 'Melting Fire' in the Garden, the Originals and some Self Seeded.

Unfortunately, due to some unintended Neglect over the last Couple of Years they are not looking their Best.

Can Heuchera 'Melting Fire' be Cut Right Back?

If not then what would be the recommended way to proceed?

Also, can Heuchera 'Melting Fire' be Propagated from Stem Cuttings?

Thanks in advance

Kevin
