Corona Prayer Plant (Calathea) Care: High-Humidity Showstopper

Striking Foliage

Calathea ‘Corona’ has broad silvery-green leaves with wide dark green edges and purplish-red undersides. Leaves fold at night like praying hands. One of the showiest Marantas.

Care Essentials

• Light: Moderate to bright indirect. No direct sun.
• Water: Evenly moist. Use distilled/rain water—sensitive to fluoride/salts.
• Humidity: Moderate to high (>50%). Humidifier/tray essential. Loves misting with rainwater.
• Temp: 65–85°F.
• Soil: Well-draining mix.
• Fertilizer: Every 2 weeks spring–summer (10-10-5 half-strength), monthly fall–winter.

Maintenance

• Repot spring for fresh mix.
• Watch for spider mites (dry air). High humidity prevents them.
• Group with other humidity-lovers (ferns, bromeliads).

Propagation

Division of rhizomes in spring/early summer.

A diva that rewards humidity with stunning leaves.
