How to Grow

Cultivation

Grow in open bark-based, epiphytic orchid compost allowing the aerial roots to hang outside. Provide bright filtered light, good ventilation and from spring to autumn mist daily for high humidity, water freely as compost dries out, allowing water to drain and apply an orchid fertiliser monthly. Provide a minimum day temperature of 17°C and night minimum of 15°C; See Phalaenopsis cultivation

Propagation

Small plantlets (keiki) may appear from the nodes on the flower stems, detach plantlets when they have developed several good roots and pot up in orchid compost, water sparingly at first, but mist daily
