  • water dropWater

    Korean feather reed grass prefers consistent moisture but is relatively drought-tolerate once established. During the first growing season, it is essential to keep the soil consistently moist to encourage a deep and extensive root system; watering once or twice a week should suffice, depending on the climate and soil conditions. Use about 1 to 1.5 gallons of water per plant for each watering session, ensuring the water penetrates deeply into the soil. After the first year, Korean feather reed grass can tolerate less frequent watering, but during prolonged dry spells or extreme heat, increase watering to maintain soil moisture.

  • sunLight

    Korean feather reed grass thrives in full sun to partial shade conditions. It performs best when it receives at least four to six hours of direct sunlight daily. This grass can adapt to various lighting conditions, but its growth might be less vigorous in too much shade. Choose a spot in your garden that receives ample sunshine for optimal growth and flowering of Korean feather reed grass.

  • thermometerTemperature

    Korean feather reed grass is hardy and can tolerate a broad range of temperatures, with an ideal growing range between 50°F and 75°F. It can survive minimum temperatures down to -20°F making it suitable for many temperate climates. During extreme heat above 90°F or sudden frost, take steps to protect the plant if necessary, although it is generally quite resilient to fluctuations in temperature.

  • scissorsPruning

    Pruning Korean feather reed grass involves cutting back the plant in late winter or early spring before new growth begins. This promotes healthy growth and prevents the grass from looking untidy. Cut the foliage back to about 4 inches from the ground using sharp shears. Pruning once a year is generally sufficient, and the best time for this is when the threat of heavy frost has passed but before new shoots appear.

  • circleLife cycle

    Calamagrostis brachytricha, also known as Korean Feather Reed Grass, begins its life cycle as a seed, which germinates in moist soil during the spring. As seedlings establish, they form dense tufts of foliage, with narrow, arching leaves that grow actively during the warm seasons. This perennial grass reaches maturity and forms distinctive, feathery plumes that are silvery-pink to purple in color by late summer to early fall, which are its inflorescences or flowering parts. Following pollination, which is typically carried out by the wind, the plant produces small grains that serve as seeds. These seeds disperse in the fall or winter, often with the help of wind or animals, to start new plants in surrounding areas. During the winter, the above-ground parts of Korean Feather Reed Grass die back, but the plant survives with its underground rhizomes, ready to regrow in the following spring.

      Late spring

    • Calamagrostis brachytricha, commonly known as Korean feather reed grass, is most effectively propagated by division. The ideal time to propagate this ornamental grass is in the spring, just as the plant begins its growth cycle. To propagate by division, a mature clump should be dug up and separated into smaller sections, ensuring that each section has a healthy portion of roots attached. These sections are then planted in well-draining soil, at the same depth they were originally growing. Water them thoroughly after planting to help establish the roots. This method allows the plant to recover from the division process throughout the growing season, resulting in a robust display by fall.
