How to Grow

Cultivation

Grow 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

Propagation

Propagation 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

Suggested planting locations and garden types

  • Houseplants
  • Conservatory and greenhouse

Pruning
