Ostrich fern: how to prune it?
- Cut the dead green fronds and the old fertile fronds off at the base.
- Watch out for the croziers already waiting in the crown: do not cut into them.
- In autumn, feel free to cut a few fertile fronds for a dried arrangement.
- Cut off runners that stray too far straight away.
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.
