Description
Caring for a Phalaenopsis orchid, commonly known as the “Moth Orchid,” is straightforward, but attention to detail ensures healthy blooms. Here’s a guide for maintaining your white Phalaenopsis orchid:
1. Light
- Needs: Bright, indirect light is ideal. Direct sunlight can scorch the leaves.
- Placement: Place near an east-facing or shaded south/west-facing window. Use sheer curtains if the sunlight is strong.
2. Watering
- Frequency: Water every 7–10 days, but adjust based on your environment. Allow the potting medium to dry out between waterings.
- Method: Use lukewarm water and avoid wetting the leaves. Ensure excess water drains out to prevent root rot.
3. Humidity
- Optimal Range: 50–70% humidity.
- Boosting Humidity: Use a humidity tray or mist the area around the plant (not the flowers or leaves directly).
4. Temperature
- Daytime: 70–80°F (21–27°C).
- Nighttime: 60–70°F (15–21°C).
- Avoid: Drafts, sudden temperature changes, and heating/cooling vents.
5. Potting Medium and Repotting
- Medium: Use a bark-based orchid mix for proper aeration.
- Repotting: Every 1–2 years, or when the medium breaks down. Best done after flowering.
6. Fertilizer
- Type: Use a balanced orchid fertilizer (20-20-20).
- Frequency: Feed every 2–4 weeks during the growing season and reduce in winter.
7. Pruning
- After flowering, cut the spike just above a node to encourage reblooming. If the spike turns brown, trim it at the base.
8. Pest and Disease Management
- Common Issues: Watch for pests like spider mites, scale, or mealybugs. Treat infestations with insecticidal soap or neem oil.
- Root Rot: Avoid overwatering and ensure good drainage.
9. Encouraging Reblooming
- Reduce nighttime temperatures by 10–15°F for a few weeks in fall to stimulate a new flower spike.
