Water: King fern thrives in high humidity and prefers consistently moist soil, requiring watering twice a week. Often grown indoors for its attractive foliage and air-purifying qualities, regular misting helps replicate its native rainforest conditions.

Pruning: King fern thrives with minimal pruning, ideally in early spring before new growth. Remove only dead or damaged fronds at the base to promote health and airflow. Avoid cutting healthy fronds. Sterilize tools to prevent infections, enhancing aesthetics and reducing disease risk.

Propagation: King fern, a fern, is mainly propagated through division by separating rhizomes with a sharp tool. Each section should have a growing tip and be planted in well-draining, humus-rich substrate. High humidity and stable moisture are essential until new growth appears, signaling a healthy root system.
