Care guide
The Cobra Fern thrives on high humidity, so mist the fronds regularly or place it on a pebble tray filled with water. Ensure the plant is kept away from direct drafts or air conditioning vents, as dry air will quickly cause the fronds to brown. During the growing season, use a balanced liquid fertilizer diluted to half-strength once a month to encourage healthy new growth.
