Fern-leaf peony: when to prune it?
Real pruning is not needed. Cut the dead foliage down to the ground in August–September.
Fern-leaf peony: how to prune it?
- Wait until the foliage is completely brown and dry: while it is green it still feeds the roots.
- Cut the stems with clean secateurs just above the ground, without damaging the red eyes.
- Put diseased foliage in the household waste, not on the compost heap.
- Cut off faded flowers after flowering.
How much to cut, and how often?
- One pruning period a year: August–September.
What does it mean for wildlife?
- Don’t cut more than you need to: what stays standing gives insects and birds food and shelter.
Caution: Do not damage the red eyes just below the ground: they produce next year’s shoots. Fern-leaf peony is poisonous: wear gloves and keep clippings away from children, pets and livestock.
