Care notes
CultivationGrow in an open bark-based orchid compost. Provide enough bright filtered light, but keep away from direct mid-day sunlight or heating source. Ideal temperatures are around 17°C at night and 20 - 25 °C during day. Mist aerial roots regularly and water the plant when almost dry - pale, silvery roots are a good indication when to water. Orchid fertiliser can be applied regularly throughout the season. See Phalaenopsis cultivation
PruningNo pruning required. Cut back flowered stem to lower node to encourage further flowering
PropagationPropagation by seed is only possible in controlled laboratory environment. Mature plants may produce sideshoots (keiki) which may be removed and potted separately into orchid propagation mix when the new roots are at least 2cm long
Pest resistanceMay be susceptible to mealybugs, aphids and scale insects
Disease resistanceGenerally disease-free; avoid watering centre of the leaf crown, to prevent bacterial rots
