How to Grow

Cultivation

Grow in a suitable, moisture-retentive, but free-draining orchid mix. Provide enough bright, filtered light, but keep away from direct sunlight or a heating source. Ideal temperatures are around 13°C minimum at night and up to maximum 25 °C during day. Water with soft water when the pot feels light when lifted. Prevent rot by avoiding leaves when watering. Orchid fertiliser can be applied regularly throughout the growing season. Reduce watering and feeding when dormant, in winter months. As with many orchids, they grow best when they are well-established and slightly pot-bound. Re-potting should be only done if the plant overgrows its container or before the potting mix starts to deteriorate - approximately once in 2-3 years. See indoor orchid cultivation for more tips.

Propagation

Propagation by seed is only possible in a controlled laboratory environment. Well-established plants can be propagated by division. Ensure each division has young enough, mature pseudobulbs to support new growth.

Suggested planting locations and garden types

  • Houseplants
  • Conservatory and greenhouse

Pruning

No pruning required other than removing spent flower stems.

Pests

May be susceptible to aphids and scale insect

Diseases

Generally disease-free. Poor air movement may cause bacterial or fungal rots. Good hygiene practice and sterilising cutting tools prevent the spread of virus diseases
