Watering. Keep the soil consistently moist but not waterlogged. Water when the top inch of soil feels dry. Mist regularly or place near a humidifier to maintain humidity.
Fertilizing. Feed every 4-6 weeks during growing seasons (spring and summer) with a balanced, water-soluble fertilizer diluted to half strength.
Boston ferns need moderate care: they prefer bright indirect light, consistent moisture, and high humidity. If conditions are too dry or light is too low, fronds may brown or drop. Regular misting and watering help keep them healthy.
