Dolce Blackcurrant Heuchera problems — and how to fix them
Dolce Blackcurrant Heuchera (Heuchera 'Dolce Blackcurrant') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown heaving
Freeze-thaw cycles push the woody crown out of the ground, exposing roots. Mulch in autumn and re-firm or replant heaved crowns in spring.
Root and crown rot
Wet, poorly drained soil rots the crown. Plant high with grit-amended drainage and avoid overwatering.
Vine weevil
Larvae chew the roots, causing sudden wilting and collapse, especially in containers. Check roots and treat with biological nematodes if found.
Colour fade in deep shade
Too little light dulls the purple toward green. Shift to brighter dappled light to restore the dark tone.
