How to Care for the Plant

Water
Water actively growing ferns plentifully, as often as necessary to keep the mixture thoroughly moist, but never allow the pot to stand in water. If the temperature falls below 12°C (54°F) water moderately, allowing the top 1cm of the mixture to dry out between waterings.
Fertilizer
One or two applications of half-strength liquid fertilizer during the active growth period will suffice.
Sunlight
Choose a position in filtered, indirect light or deep shade.
