Indoor Coconut Palm Care: Light, Water, and Humidity

Growing Coconut Palm (Cocos nucifera) Indoors

Coconut palms are challenging houseplants—they demand high light, humidity, and excellent drainage.

Key Requirements

• Light: Lots of direct sun (south/west window) or very bright indirect.
• Water: Water thoroughly when top inch of soil is dry. Use filtered/distilled water if tap is hard.
• Humidity: High—use humidifier or pebble tray.
• Temperature: Minimum 55°F (13°C).
• Soil: Fast-draining palm/cactus mix.
• Fertilizer: Only during active growth, standard fertilizer at half strength.
• Pests: Watch for spider mites on leaf undersides.

Conservatory placement 6 inches back from a window may not provide enough light. Consider supplemental grow lights in winter.
