Care Instructions
Humidity is key – Maidenhair Ferns thrive in consistently humid environments. Bathrooms or grouped plants help boost ambient moisture. If air is dry, use a pebble tray or humidifier.
Watering – Keep soil lightly moist at all times. Water when the top layer begins to dry out, but never let the pot fully dry. Use room-temperature water.
Light – Prefers bright, indirect light. Avoid direct sun, which can scorch its delicate fronds.
Soil – Use a peat-based, well-draining mix. A blend formulated for ferns or African violets works well.
Temperature – Keep between 60–75°F (16–24°C) and away from cold drafts or dry heat sources.
Maintenance – Trim off any brown or crispy fronds to encourage healthy new growth. Rotate the pot occasionally for even shape.
Common Problems
Crispy leaves: Often from low humidity or missed waterings
Drooping or leaf loss: Usually due to underwatering or dry air
Brown tips: Result of inconsistent watering or overly dry air
