Care Instructions

  • Light: Prefers bright, indirect light but adapts well to medium and low-light conditions. Avoid prolonged direct sunlight, which can damage its fronds.
  • Water: Keep the soil evenly moist but not soggy. Water when the top inch of soil feels dry. Avoid letting the soil completely dry out.
  • Humidity: Thrives in moderate to high humidity. Mist occasionally or use a pebble tray to maintain ideal conditions in drier environments.
  • Feeding: Fertilize every 6-8 weeks during the growing season (spring and summer) with a diluted liquid fertilizer. Reduce feeding in fall and winter.
  • Temperature: Maintain temperatures between 60°F and 75°F. Protect from cold drafts and temperatures below 50°F.
  • Soil: Use a well-draining potting mix rich in organic matter, such as one formulated for ferns or tropical plants.
