Care Guide
Japanese Painted Fern Care Guide Watering: Keep the soil consistently moist but never waterlogged. This fern does not tolerate drying out. Water when the surface of the soil just begins to feel slightly less damp. Lighting: Indoors, place in a spot with bright, indirect light. Avoid direct sunlight, which will scorch the delicate silvery fronds. Humidity: Requires high humidity (50% or higher). Use a humidifier, pebble tray, or group with other plants. Browning edges usually indicate dry air. Temperature: Prefers cool to average room temperatures (60-75°F). Keep away from drafty windows or heating vents. Seasonal Care: As a deciduous fern, it may go dormant in winter if temperatures drop or light levels decrease significantly. If fronds die back, reduce watering and wait for new growth in spring. Common Issues: Crispy fronds indicate low humidity or underwatering, while yellowing leaves suggest overwatering or poor drainage.
