Growing it

Propagation: division, spores
When to plant: spring, early autumn
Overwintering: The fronds will die back naturally in autumn, so you can trim them to the ground once they turn brown. Apply a light layer of mulch to protect the rhizomes during the coldest months.
In containers: It grows well in pots if kept in a shaded, humid spot with a minimum 20 centimeter diameter container.

Division

1. Carefully dig up the clump in early spring.
2. Gently pull the rhizomes apart into smaller sections.
3. Replant the divisions immediately in moist, shady soil.

Pair this fern with other woodland plants that appreciate rich, humusy soil and consistent moisture.
