Catasetum expansum green orchid

50 seeds

• Time to Seed:

  • The best time to seed Catasetum expansum in the Gulf region is during the cooler months (October to March) when temperatures are lower, which supports better germination rates.

• Soil Preparation:

  • Use a well-draining, slightly acidic medium. A combination of orchid bark, perlite, and sphagnum moss works well for Catasetum expansum.

• Planting Method:

  • Lightly scatter the seeds on the surface of the growing medium or gently press them into the substrate (1-2 mm deep).

  • Keep the medium moist but avoid over-saturating it.

• Temperature and Humidity:

  • Ideal temperature: 20-30°C (68-86°F).

  • High humidity (60-80%) is essential for the seeds to germinate. You can use a humidity dome or mist the area regularly to keep the moisture levels high.

• Light Conditions:

  • Catasetum expansum prefers bright, indirect light. Direct sunlight may burn the seedlings, so it’s best to keep them in a spot with filtered light.

• Watering:

  • Keep the medium moist at all times but ensure proper drainage to prevent standing water, which can cause root rot.

• Transplanting:

  • Once the seedlings are large enough to handle (around 2-3 cm), transplant them into individual pots or a larger container with a well-draining orchid mix.
