Troubleshooting
Marmalade Heuchera problems — and how to fix them
Marmalade Heuchera (Heuchera 'Marmalade') 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 and root rot
Standing moisture rots the crown despite this cultivar's heat tolerance. Plant high in free-draining, grit-amended soil.
Crown heaving
Repeated winter freeze-thaw pushes the crown upward. Mulch for winter and re-firm exposed crowns in spring.
Vine weevil
Adults notch leaf margins and larvae eat roots, causing collapse in pots. Inspect roots and apply nematodes if grubs appear.
Colour washing out
In deep shade the warm amber dulls; the orange tones are strongest in cool conditions and brighter light. Adjust siting for vivid colour.
