Sterile Seeding: Orchid seeds are microscopic (like dust) and lack food reserves. They cannot be grown by simply planting them in soil. They must be sown in a sterile laboratory environment on a nutrient agar medium (e.g., Vacin and Went or Malmgren) to prevent contamination.
Mycorrhizal Symbiosis: In nature, these orchids depend on a specific fungus found in Australian soil to germinate. Without this symbiotic relationship, they rarely survive even after germination.
Temperature Control: Keep seeds at a constant 18–25°C (64–77°F) for germination. In the Gulf, temperatures exceeding 30°C (86°F) can be fatal to the delicate protocorms (developing seedlings).
Light: Provide bright, indirect light or filtered shade. Direct Gulf sunlight will scorch the plants instantly.
Watering: Use only distilled or rainwater. The medium must stay moist but never waterlogged; overwatering leads to root rot.
Potting Mix: Once large enough (which can take years), they require a very well-draining, sandy loam terrestrial mix.
