Royal fern: how to prune it?
- Cut the dead fronds off at the base.
- Watch out for the croziers already waiting in the crown: do not cut into them.
- No other pruning is needed; the spore clusters can simply stay.
- Put the old fronds on the compost heap or use them as mulch under shrubs.
How much to cut, and how often?
- One pruning period a year: March.
What does it mean for wildlife?
- As a native plant, it feeds more insects than a non-native species.
