This fern thrives in high humidity and consistently moist, well-draining soil. It prefers indirect, bright light and should be protected from direct sunlight, which can scorch its delicate fronds. Keep environmental temperatures between 60-75°F (15-24°C). Avoid letting the soil dry out completely between waterings, but also ensure good drainage to prevent root rot. Misting regularly or placing the pot on a pebble tray with water can help maintain humidity.
