Troubleshooting
Coral Bells 'Caramel' problems — and how to fix them
Coral Bells 'Caramel' (Heuchera 'Caramel') 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
Winter freeze-thaw lifts the shallow crown out of the soil. Replant or firm it back deeper in spring and apply mulch for insulation.
Vine weevil
Root-eating larvae cause sudden wilting, particularly in pots. Inspect the rootball, apply nematodes, and remove any C-shaped grubs found.
Loss of leaf colour
In too much shade the amber tones fade toward green; move to a brighter part-shade spot to restore the caramel colouring.
Powdery mildew and rust
Damp, crowded conditions invite fungal disease. Space plants, water at the base, and remove affected foliage to improve airflow.
