Description
- Dendrobium orchids, like the Thongchai Gold Pramote, are prized for their vibrant colors and long-lasting blooms. Proper care is essential for them to thrive, especially when they’re in the seedling stage. Here’s a guide to caring for Dendrobium seedlings:
1. Light
- Intensity: Provide bright, indirect light. Dendrobiums prefer 50-70% filtered sunlight.
- Avoid direct sunlight: Seedlings are more delicate and can get scorched if exposed to direct sunlight.
- Best location: Place them near an east-facing window or under shade cloth in a greenhouse.
2. Temperature and Humidity
- Optimal temperature:
- Day: 75–85°F (24–29°C)
- Night: 60–65°F (15–18°C)
- Humidity: Maintain 50-70% humidity.
- Use a humidity tray or a misting system to maintain adequate moisture around the plant.
3. Watering
- Frequency: Water seedlings every 3–5 days, or when the top layer of the medium feels dry. Do not let the roots sit in water.
- Water quality: Use filtered or rainwater, as these orchids are sensitive to salts and impurities.
- Morning watering: Always water in the morning to allow the leaves to dry by evening, preventing fungal issues.
4. Potting and Medium
- Medium: Use a fine-grade orchid mix suitable for seedlings (e.g., bark, sphagnum moss, or perlite).
- Repotting: Repot seedlings once a year or when they outgrow their pots. Use a small pot to avoid excess moisture retention.
5. Fertilizer
- Frequency: Fertilize weekly with a diluted orchid fertilizer (¼ to ½ strength).
- Type: Use a balanced fertilizer (e.g., 20-20-20) or one specifically formulated for orchids.
- Switching fertilizers: During active growth, use a fertilizer higher in nitrogen; switch to one higher in phosphorus when the plant starts forming spikes.
6. Air Circulation
- Ensure good airflow to prevent fungal and bacterial issues. Use fans if growing indoors.
7. Pests and Diseases
- Watch for common pests like spider mites, aphids, or mealybugs.
- Use insecticidal soap or neem oil as needed, ensuring seedlings are not stressed before application.
8. Rest Period
- Some Dendrobiums require a cooler, drier rest period after blooming. However, seedlings typically need consistent care until they mature.
With consistent care, Thongchai Gold Pramote seedlings will grow into healthy plants, ready to produce stunning blooms. Let me know if you want specifics on propagation or troubleshooting! 🌱
