Dendrobiun Seedlings Thongchai gold x udom yellow

Caring for Dendrobium seedlings (Thongchai Gold x Udom Yellow) involves understanding the specific needs of this hybrid orchid. Here’s a detailed care guide:

1. Light

• Bright, Indirect Light: Provide bright but filtered light. They thrive in 50-70% shade, avoiding direct sunlight to prevent leaf scorch.
• Use a shade cloth or place them in a spot with morning sun and afternoon shade.

2. Temperature

• Warm Growers: They prefer warm temperatures:
  • Day: 24–30°C (75–86°F)
  • Night: 18–20°C (64–68°F)
• Avoid sudden temperature drops. Protect them from frost or extreme heat.

3. Watering

• Moderate Watering:
  • Water seedlings regularly, allowing the medium to dry slightly between watering. Overwatering can cause root rot.
  • Reduce watering during their rest period (winter or when growth slows).
• Use distilled, rainwater, or low-mineral water for best results.

4. Humidity

• High Humidity (50-70%):
  • Place a humidity tray or use a humidifier if the air is dry.
  • Good airflow is essential to prevent fungal issues.

5. Potting Medium

• Use a well-draining medium:
  • Fine-grade bark, sphagnum moss, or a mix with perlite for seedlings.
  • Repot every 1-2 years or when the medium breaks down.

6. Fertilizing

• Use a balanced orchid fertilizer (e.g., 20-20-20) at quarter strength:
  • Fertilize every 2 weeks during active growth (spring/summer).
  • Reduce or stop feeding during rest periods.
• A fertilizer higher in phosphorus can encourage flowering as the plant matures.

7. Air Circulation

• Keep them in a well-ventilated area to prevent fungal or bacterial infections.
• Avoid overcrowding plants to ensure proper airflow.

8. Rest Period

• Some Dendrobiums (especially hybrids) require a rest period during winter:
  • Reduce watering and fertilizing.
  • Keep the plant in a cooler environment.

9. Pest and Disease Management

• Watch for common pests like aphids, spider mites, or scale insects.
• Use insecticidal soap or neem oil if necessary.
• Ensure leaves are dry before nightfall to prevent fungal infections.
