Light:
Indirect Light:
Calatheas prefer bright, indirect light. Direct sunlight will scorch their delicate leaves.
A location near a north- or east-facing window is often ideal.
Avoid Direct Sun:
Keep them away from direct afternoon sun.
Watering:
Consistent Moisture:
Maintain consistently moist soil, but avoid overwatering.
Water when the top inch of soil feels slightly dry.
Use filtered, distilled, or rainwater, as they are sensitive to chemicals in tap water.
Avoid Soggy Soil:
Ensure proper drainage to prevent root rot.
Humidity:
High Humidity:
Calatheas thrive in high humidity.
Increase humidity by:
Using a humidifier.
Misting the leaves regularly.
Placing the plant on a pebble tray with water.
Temperature:
Warm Temperatures:
Maintain temperatures between 65-80°F (18-27°C).
Avoid cold drafts and sudden temperature changes.
Soil:
Well-Draining Soil:
Use a well-draining potting mix, such as one containing peat moss, perlite, and orchid bark.
Fertilizing:
During Growing Season:
Fertilize monthly during spring and summer with a diluted liquid fertilizer.
Avoid Winter Fertilizing:
Do not fertilize during the dormant winter months.
Key Considerations:
Water Quality:
Calatheas are sensitive to tap water, so using filtered or rainwater is best.
Humidity is Crucial:
Maintaining high humidity is essential for preventing brown, crispy leaf edges.
Leaf Movement:
Calatheas are known as prayer plants because they raise and lower their leaves depending on the time of day. This is normal.
