Corsican hellebore: when to prune it?
After flowering, in April–May, cut the flowered stems off at the base.
Corsican hellebore: how to prune it?
- Cut each stem that has flowered just above the ground.
- Leave the young stems without flowers: they will flower next year.
- If you want seedlings, leave one stem until the seed pods split open.
- Remove damaged or black-spotted leaves as you go, wearing gloves.
How much to cut, and how often?
- One pruning period a year: April–May.
What does it mean for wildlife?
- Corsican hellebore flowers in February–April, when it attracts bees.
- If pruning falls during flowering, wait until it is over or leave part of the plant to flower, so bees and butterflies still benefit.
Caution: Never cut off the young, non-flowering stems: they carry next year’s flowers. Corsican hellebore is poisonous: wear gloves and keep clippings away from children, pets and livestock.
