Marginal wood fern (Dryopteris marginalis): how to prune it?
- Cut off only the brown, damaged or flattened fronds at the base.
- Leave healthy, green fronds; they stay attractive.
- Wear gloves: the scales on the stalks can irritate.
- Remove dead fronds from the heart of the crown.
How much to cut, and how often?
- One pruning period a year: March.
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 cut off new, rolled-up fronds: they are very fragile.
