Care
Keep the soil consistently moist but never soggy to mimic its natural forest floor habitat. Watch for browning frond tips, which usually signal that the air is too dry or the soil has dried out too much. A layer of organic mulch helps keep the roots cool and retains necessary moisture.
- Watering
- Water whenever the top inch of soil feels dry to the touch.
- Feeding
- Apply a balanced, diluted liquid fertilizer during the active growing season.
- Pruning
- Trim away old or damaged fronds in early spring before new growth emerges.
- Repotting
- Move to a slightly larger container only when the roots have filled the current pot.

Growing it
- Propagation

- When to plant
- spring, autumn
- Overwintering
- Leave the old fronds in place until early spring to protect the crown, then trim them back just as new growth begins to emerge.
- In containers
- It grows well in containers at least 30 cm wide, provided the soil remains damp.
Division
- 1. Carefully dig up the clump in early spring.
- 2. Use a sharp knife to divide the root mass into smaller sections.
- 3. Replant immediately in moist, organic-rich soil.
Plant these in groups of three or five to create a lush, natural woodland effect.
