How to grow

Cultivation Grow in fertile, humus-rich, moist but well-drained soil, in full sun or partial shade. Protect from cold drying winds. In a container grow in a loam-based compost and feed with a balanced liquid fertiliser on a monthly basis during the growing season. May remain clump-forming in poor or dry soils but can become invasive in warm, moist or favourable conditions; see bamboo control and bamboo cultivation

Propagation Propagate by division in spring

Suggested planting locations and garden types Hedging & Screens Architectural Patio & Container Plants

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
