Bottlebrush sedge (Carex hystericina) is a wetland grass. This species has been shown to have the potential to suppress the invasive species Phalaris arundinacea, although under certain conditions, it can become weedy itself. This plant is a good pioneer species to use in the restoration of sedge meadows.

Water:
Native to wetlands, bottlebrush sedge prefers consistently moist soil and high humidity. It thrives with weekly watering, tolerating short dry spells. Typically grown outdoors, bottlebrush sedge benefits from seasonal rainfall, which supports its moisture needs for lush growth.
Fertilize:
Fertilizing bottlebrush sedge promotes growth and health. Apply mulch or compost in spring, avoiding contact with foliage. This method provides nutrients and retains moisture. Adjust fertilization for young or divided plants, avoiding over-fertilization. Reduce application in fall to protect against frost damage.
Pruning:
Bottlebrush sedge features unique seed heads resembling bottlebrushes. Prune in early spring to remove damaged foliage and old stalks, promoting new growth. Regular pruning encourages density and disease prevention, while clean tools help avoid infections, resulting in a healthier, more attractive plant.
Propagation:
Bottlebrush sedge propagates best through division, which involves separating dense clumps to establish new root systems. Maintaining moisture, soil fertility, and appropriate light conditions similar to bottlebrush sedge's natural habitat is essential for successful propagation and healthy growth.
