In March, before the new fronds appear.
What else to prune in those months? March
Japanese painted fern: how to prune it?
- Leave the dead fronds standing over winter: they protect the rhizome.
- In March, cut all the old brown fronds off just above the ground.
- In summer, remove any scorched or damaged fronds if needed; new ones will follow.
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: Watch out for the young fiddleheads: they only appear in April–May and snap easily.
