Watering
Keep the soil evenly moist but not waterlogged.
Feeding
Apply a balanced, slow release fertilizer once in early spring.
Pruning
Cut the plant back to a few inches above the ground in late winter.
Repotting
Divide the clumps every few years to keep the plant vigorous.

    Growing it

    Propagation
    division, seed
    When to plant
    spring, autumn
    Overwintering
    Leave the dried foliage standing through winter to protect the crown and provide winter interest. Trim back to the base in early spring before new growth emerges.
    In containers
    It grows well in large containers, provided the soil is kept consistently moist.

    Division

    1. Dig up the mature clump in early spring.
    2. Use a sharp spade or knife to divide the clump into smaller sections.
    3. Ensure each section has healthy roots and foliage.
    4. Replant immediately in prepared soil.
    5. Water thoroughly until established.

    Pair this grass with moisture loving perennials to ensure consistent soil hydration across the bed.
