How to Grow

Cultivation

Grow in moderately fertile, moist but well-drained or damp soil in partial shade, or full sun where soil stays damp in spring and summer. Usually clump-forming but creeping rootstock can become invasive in warm, moist or favourable conditions and need restraining ; see bamboo control and bamboo cultivation

Propagation

Rhizome cuttings and the division of established plants in Spring

Suggested planting locations and garden types

Architectural
Hedging and screens

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

May be susceptible to slugs

Diseases

Generally disease-free
