Care Guide for Peacock Fern (Selaginella willdenowii)

Light Requirements

• Bright, Indirect Light:
  • Prefers dappled light, similar to the conditions on a rainforest floor.
  • Avoid direct sunlight, which can scorch its delicate leaves and reduce the iridescent coloring.
  • Ideal placement: Near an east or north-facing window or under grow lights indoors.

Temperature and Humidity

• Temperature:
  • Thrives in temperatures between 60-80°F (16-27°C).
  • It does not tolerate cold temperatures or frost and should be kept away from drafts.
  • Minimum temperature: 50°F (10°C).
• Humidity:
  • Requires high humidity levels (70% or higher).
  • Great for terrariums, greenhouses, or bathrooms with natural humidity.
  • Use a humidifier or a pebble tray with water to maintain moisture around the plant.

Watering

• Keep Soil Evenly Moist:
  • Water regularly to keep the soil consistently moist but not waterlogged.
  • Avoid letting the soil dry out completely, as this can cause the plant to wilt.
  • Use distilled or rainwater if possible, as tap water may contain minerals that can harm the plant.

Soil

• Well-Draining, Humus-Rich Soil:
  • Use a mix designed for tropical plants, such as a combination of peat moss, perlite, and organic matter.
  • Ensure good drainage to prevent root rot while retaining some moisture.

Fertilization

• Light Feeder:
  • Fertilize once a month during the growing season (spring and summer) with a diluted balanced liquid fertilizer (e.g., 10-10-10 or 20-20-20).
  • Avoid over-fertilization, as this plant is sensitive to salts and chemicals.

Pruning and Maintenance

• Minimal Pruning Required:
  • Trim any brown, dry, or damaged fronds to encourage new growth.
  • Pinch back leggy growth to maintain a compact, bushy appearance.

Propagation

Peacock Fern can be propagated by division or stem cuttings:

1. Division:
   • During repotting, gently separate the root ball into smaller sections.
   • Plant each section in its own pot with fresh soil.
2. Stem Cuttings:
   • Cut a healthy stem with a few nodes.
   • Place it in moist soil or water until roots form.
   • Keep the cutting in a humid environment during the rooting process.

Common Problems and Solutions

1. Wilting or Browning Leaves:
   • Cause: Low humidity, underwatering, or cold temperatures.
   • Solution: Increase humidity, water regularly, and keep the plant warm.
2. Faded or Dull Colors:
   • Cause: Insufficient light.
   • Solution: Move the plant to a brighter location with indirect light.
3. Root Rot:
   • Cause: Overwatering or poor drainage.
   • Solution: Ensure the pot has drainage holes and allow excess water to drain away.
4. Pests:
   • Occasionally susceptible to fungus gnats, spider mites, or mealybugs.
   • Solution: Use insecticidal soap or neem oil and maintain proper air circulation.
