Watering
Keep the soil evenly moist but not waterlogged.
Feeding
Apply a balanced liquid fertilizer diluted to half strength during the growing season.
Pruning
Remove dead or damaged fronds in late winter or early spring before new growth appears.

    Growing it

    Propagation
    division, spores
    When to plant
    spring, autumn
    Overwintering
    Leave the old fronds on the plant until spring to protect the crown from frost. Clear away dead debris once new growth appears.
    In containers
    It grows well in large pots that provide enough room for the root system to expand.

    Division

    1. 1. Carefully dig up the clump in early spring.
    2. 2. Use a sharp spade to divide the root mass into smaller sections.
    3. 3. Replant the divisions immediately in moist, organic soil.

    Pair this fern with other moisture loving woodland plants to create a lush, low maintenance shade garden.
