• Division: In early spring, divide established clumps, ensuring each section has roots and buds. Replant the divisions immediately in prepared soil.

Routine care includes:

• Keeping the soil consistently moist, particularly during dry periods.
• Applying a layer of mulch annually to retain moisture and enrich the soil.
• Removing dead fronds in late autumn to tidy the plant and prepare for winter dormancy.
