Polystichum tsus-simense or Korean Rock Fern prefers bright, indirect light and consistent moisture. Use an organic well-draining potting mix and water when the soil drys 1" below the surface. Korean rock ferns live happily about 1-2 feet away from windows and will tolerate low light. Increase the humidity around your fern with a humidifier or set on a pebble tray. Maintain 65-75 degrees Fahrenheit and avoid placing near drafts. *Pet friendly*
