About Nephrolepis undulata
Nephrolepis undulata, or Wavy Sword Fern, is a perennial tropical fern distinguished by its long, arching fronds with distinctively wavy margins. Its bright green foliage and elegant habit make it ideal for hanging baskets or as a decorative houseplant, adding a touch of freshness to any space. It's an excellent choice for bathrooms or kitchens where it can benefit from ambient humidity.

Care tips
This fern thrives in bright, indirect light; avoid direct sunlight which can scorch its fronds. Keep the substrate consistently moist, but not waterlogged, watering when the top layer of the substrate begins to dry out. It prefers an organic-rich, well-draining potting mix. A common mistake is allowing the substrate to dry out completely, which can cause the frond tips to turn brown.

- What kills it
- Dry air and lack of humidity, which quickly dries its fronds. Also, too much direct sun and constantly waterlogged soil.
