Orchid Care Essentials: Light, Temperature, and Watering for Thriving Blooms

Light

Bright, filtered light is ideal. Direct sun burns leaves and flowers. In bloom, protect from all direct rays. Leaves should be light green; dark green indicates insufficient light.

Temperature

• Cool-growing (e.g., Cymbidium): 50–65°F night, 65–75°F day.
• Intermediate (e.g., Cattleya): 55–65°F night, 70–80°F day.
• Warm-growing (e.g., Phalaenopsis): 65–70°F night, 75–85°F day.

Provide a 10–15°F day/night differential. Use fans for air circulation.

Watering and Fertilizing

• Water when potting mix is nearly dry; frequency varies by type, pot, and environment.
• Use tepid water; avoid softened water.
• Fertilize weakly, weekly with a balanced orchid fertilizer. Flush monthly to prevent salt buildup.

Result

Consistent attention to these factors yields healthy plants and spectacular, long-lasting flowers.
