How to grow

Cultivation Grow in fertile, humus-rich, moist but well-drained soil, best in partial shade. Protect from cold drying winds. Rampant, creeping rootstock can become very invasive in warm, moist or favourable conditions and need restraining ; see bamboo control and bamboo cultivation

Propagation Propagate by young rhizome cuttings and the division of established plants in Spring

Suggested planting locations and garden types Ground Cover Hedging & Screens Architectural

How to care

Pruning Remove weak, dead, damaged or spindly stems in spring and thin to show off stems to best effect. Cut out any flowering shoots promptly to discourage more from forming - see bamboo cultivation

Pests Slugs may damage new shoots

Diseases Generally disease free
