Asian Sword Fern
Nephrolepis brownii
An elegant and hardy fern species, Nephrolepis brownii, often referred to as the Asian Sword Fern, is celebrated for its lush, arching fronds and vigorous growth habit.

Care Guide
Nephrolepis brownii Care Guide
1. Light: Provide bright, filtered light. Avoid direct afternoon sun, which can scorch the delicate pinnae. A north or east-facing window is ideal.
2. Watering: Keep the soil consistently moist but never waterlogged. Water when the surface of the soil feels slightly dry to the touch. Ensure the pot has excellent drainage to prevent root rot.
3. Humidity: This fern thrives in 60-80% humidity. Use a pebble tray, a humidifier, or place the plant in a naturally humid room like a bathroom.
4. Temperature: Maintain temperatures between 60°F and 80°F (15°C-27°C). Protect it from cold drafts and heating vents.
5. Seasonal Maintenance: In winter, growth slows down, so reduce watering frequency and stop fertilizing. Prune away brown or dead fronds at the base to encourage new growth.
