How to Grow

Cultivation

Requires day temperatures around 16°C and 10°C at night. Provide good light levels, but avoid direct sunlight. Pot firmly into epiphytic or terrestrial orchid compost, water thoroughly when compost is almost dry, allow to drain and use fertiliser at every third watering. Water sparingly in winter. Place outside in dappled shade during the summer months to aid flower initiation. This cymbidium hybrid is often grown in a basket because of the pendulous nature of the flower spikes. See cymbidium cultivation

Propagation

Propagate by division of pseudobulbs after flowering, in early or mid spring when pot-bound
