Care Guide

Cultivation

Grow in moist but well-drained, humus rich, acidic soil, in partial or dappled shade. Choose a site away from frost pockets and sheltered from strong winds, and do not allow plants to dry out. Mulch annually, ideally with leaf mould. See rhododendron cultivation for more detailed advice

Pruning

Minimal pruning required, see pruning group 8 (evergreens). Deadhead if practical, to promote vegetative growth rather than seed production

Propagation

Propagate by semi-ripe cuttings in late summer, by layering in autumn, or by grafting in winter
