Troubleshooting
Christmas Rose problems — and how to fix them
Christmas Rose (Helleborus niger) 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.
Hellebore leaf spot
Fungal black blotches on leaves; remove infected foliage and tidy old leaves in late winter to improve airflow and display the white flowers.
Crown and root rot
Wet, heavy winter soils rot the crown. Plant in sharply drained, alkaline soil raised slightly if necessary, and avoid waterlogged spots.
Resents disturbance
H. niger dislikes being moved or divided and may sulk for a season or two afterward; site it permanently and disturb as little as possible.
Mud-splashed flowers
Low-held white blooms are easily soiled by rain splash. A gravel or leaf-mould mulch keeps the flowers cleaner through winter.
