Huperzia (Lycopodium) carinata XXL

Huperzia carinata (formerly known as Lycopodium carinatum), commonly called Tassel Fern, is an epiphytic or lithophytic fern ally from the Lycopodiaceae family. It is prized for its pendulous, trailing growth and delicate, feathery fronds, making it an excellent choice for hanging displays.

Light

• Prefers bright, indirect light or dappled sunlight.
• Can tolerate morning sun, but avoid intense afternoon sun, which can scorch the delicate foliage.
• Grows well under shade netting (50-70%) or in a well-lit greenhouse.

Temperature & Humidity

• Thrives in warm, humid conditions (20-30°C / 68-86°F).
• Requires high humidity (60-80%) to thrive; mist regularly or use a humidifier in dry environments.
• Needs good air circulation to prevent fungal infections.

Watering

• Water frequently to keep the medium evenly moist but not waterlogged.
• Best watered with rainwater, distilled, or filtered water to avoid mineral buildup.
• In hot weather, water daily.
• Reduce watering slightly in cooler months, but never let it dry out completely.

Growth & Propagation

• Grows slowly but can become long and lush over time.
• Can be propagated by:
  • Stem cuttings (place in sphagnum moss with high humidity).
  • Division (separating mature clumps carefully).
  • Spores, though this method is slow and challenging.

Common Issues

• Browning tips: Usually due to low humidity or hard water—increase misting and use purified water.
• Yellowing leaves: May indicate overwatering or lack of nutrients.
• Slow growth: Normal for this species, but ensuring optimal humidity and feeding helps.
• Pests: Watch for scale insects, spider mites, and mealybugs; treat with neem oil or insecticidal soap.
