Water regularly, especially during the establishment phase and dry periods. Keep the soil consistently moist but not waterlogged.

Once established, Miscanthus sinensis is moderately drought-tolerant, but supplemental watering will ensure optimal growth and flowering.

Cut back all foliage to about 10-15 cm from the ground in late winter or early spring before new growth emerges. This removes dead material and tidies the plant.

Avoid pruning in fall, as the dead foliage provides winter interest and insulation.

Propagate by division in early spring. Dig up established clumps and carefully divide them into smaller sections, ensuring each section has roots and shoots. Replant immediately at the same depth as before.

Repotting is generally not necessary for outdoor plantings as Miscanthus sinensis is a large, clump-forming perennial. For container-grown specimens, repot every 2-3 years into a larger container with fresh potting mix in spring.
