When to plant and prune Hellebore
Helleborus × hybridus (Oriental hybrids)
Cut back the old tatty leaves of Helleborus x hybridus in late winter, just before flowering — this is essential to display the nodding flowers properly and reduces hellebore leaf spot disease, but don't cut back other hellebore species the same way.
Planting, flowering and pruning by region
Pruning is driven by dormancy rather than frost, so it is not shifted by region — the same cut is right in Inverness and in Penzance. Planting windows do move.
| Where you are | Plant | In flower | Prune |
|---|---|---|---|
| South West Coast and Cornwall | mid September to late December | early January to late March | late January to late February |
| South Coast and Channel | mid September to late December | early January to late March | late January to late February |
| Greater London (Urban Heat Island) | mid September to late December | early January to late March | late January to late February |
| South East and Home Counties | mid September to late December | early January to late March | late January to late February |
| East Anglia | mid September to late December | early January to late March | late January to late February |
| Midlands and Lowland Wales | mid September to late December | early January to late March | late January to late February |
| Wales and West Coast | mid September to late December | early January to late March | late January to late February |
| Northern England | mid September to late December | early January to late March | late January to late February |
| Scotland Lowlands and Central Belt | mid September to late December | early January to late March | late January to late February |
| Scotland Highlands and Islands | mid September to late December | early January to late March | late January to late February |
| Northern Ireland | mid September to late December | early January to late March | late January to late February |
| Channel Islands and Isle of Man | mid September to late December | early January to late March | late January to late February |
How to prune it
Cut back old leaves to the base in late winter/early spring before/as flowers emerge.
Severity: moderate.
Feeding
Borders rarely need feeding; if growth is poor it's usually drought or shade rather than nutrients. Containers need regular balanced liquid feed.

Growing notes
One of the most valuable winter nectar sources for early bumblebees on mild days — leave a few flowers unpicked even if growing for cutting.
What usually goes wrong
- hellebore leaf spot
- hellebore black death (viral, incurable — destroy affected plants)
- aphids
- leaf miner (H. foetidus only)
