Care notes
CultivationMay be grown outdoors in frost free areas, otherwise best grown under glass or in containers that can be moved indoors over winter. Grow in moist but well-drained, humus rich, acidic soil or in an ericaceous potting mix, and position in partial or dappled shade. See rhododendron cultivation for more detailed advice
PruningGenerally requires minimal pruning, though may need restrictive pruning if grown under glass; see pruning group 8 (evergreens). Deadhead if practical, to promote vegetative growth rather than seed production
PropagationPropagate by semi-ripe cuttings in late summer, or by grafting in winter
Pest resistanceMay be susceptible to vine weevil, rhododendron and azalea whitefly, rhododendron leafhopper, Pieris lacebug, scale insects, caterpillars and aphids
Disease resistanceMay be susceptible to powdery mildews, honey fungus, silver leaf and Phytophthora, as well as more specific Rhododendron diseases
