Watering. Keep soil consistently moist but not soggy. Water when the top inch of soil feels dry. Increase humidity by misting or placing near a humidifier.
Fertilizing. Feed with a balanced, water-soluble fertilizer diluted to half strength every 4-6 weeks during the growing season (spring and summer). Avoid over-fertilizing to prevent leaf burn.
Nephrolepis obliterata is a moderately easy fern to care for. It prefers indirect light and high humidity. Avoid letting the soil dry out completely, but do not overwater. It may develop brown leaf tips if conditions are too dry or if over-fertilized.
