How to Grow

Cultivation

Grow in a fine-grade, bark-based epiphytic orchid compost. Provide bright filtered light, good ventilation and in spring and summer water freely as compost dries out, use orchid fertiliser at every third watering and mist regularly for high humidity. Reduce watering in winter and allow a 4 week period of day time temperature around 10°C to encourage flowering. See Oncidium (warm) cultivation

Propagation

Propagate by division when plants are large enough to be divided into clumps of 2 - 3 pseudobulbs and overflowing the pot
