Heuchera Plant Care:
Benefits from deadheading. Watch for frost heaving - mulch can help. In cold climates, winter mulch applied after the ground freezes will help prevent root heaving. It keeps the mature crown in contact with the soil and keeps the soil moist in the summer as well. Must have good drainage over the winter, though, so don't over-do the overwintering mulching. Shear off any damaged leaves in early spring to make room for new foliage. Can be divided every 3 years in spring.
