Nephrolepis cordifolia (Fishbone Fern)

The Fishbone Fern (Nephrolepis cordifolia) is a pet-friendly, air-purifying houseplant that thrives in bright, indirect light and high humidity. It prefers moist, well-drained soil and is generally pest-resistant. Perfect for indoor spaces, it adds lush greenery while being easy to care for and safe around pets.

Care Requirements

  • Light:
    Thrives in bright, indirect light but can tolerate low light conditions. It’s best to avoid excessive direct sunlight, which can damage the fronds.

  • Watering:
    Prefers consistently moist soil, but ensure it is not soggy. Reduce watering during the winter months when the plant’s growth slows.

  • Soil:
    Requires well-draining soil. Make sure the pot has drainage holes to prevent water retention and root rot.

  • Temperature:
    Grows well in average indoor temperatures. The ideal temperature range is 60–75°F (15–24°C). Fishbone ferns thrive in high humidity.

  • Fertilizer:
    During the growing season (spring and summer), use a balanced liquid fertilizer every 4–6 weeks to support healthy growth.

Care Tips

  • Keep the plant clean by wiping the fronds with a damp cloth to remove dust and improve photosynthesis.

  • Rotate the plant occasionally for even light exposure, especially if growing in a spot with uneven light.

Common Problems

  • Brown, crispy fronds: This can be a sign of low humidity or underwatering. Increase humidity or adjust watering schedules accordingly.

  • Yellowing fronds: Often a result of overwatering or poor drainage.

Additional Information

  • Toxicity:
    The Fishbone Fern is non-toxic, making it a great choice for pet-friendly homes. However, young fronds may cause skin irritation, especially for individuals sensitive or allergic to plants.

  • Pest Resistance:
    Generally pest-resistant. Regular inspections are recommended. If pests appear, treat with neem oil or insecticidal soap. Maintain good air circulation to avoid pest issues.

  • Air Purification:
    Known for its excellent air-purifying properties, the Fishbone Fern helps improve indoor air quality and increases humidity.
