Doryopteris Cordata, Antenna Fern – Rare

Selling size: Single Plant | Pot Included | Free shipping

Doryopteris cordata, commonly known as the Antenna Fern, is a unique and beautiful tropical fern that makes a great houseplant, especially for those who can provide the high humidity it craves. Its distinctive appearance, with low-lying, lobed basal fronds and taller, upright fertile fronds resembling antennae, sets it apart.

Here’s a comprehensive guide to caring for your Doryopteris Cordata, Antenna Fern:

1. Light:

• Bright, indirect light is ideal. Mimic its natural habitat in the understory of forests where it receives dappled sunlight.
• Avoid direct sunlight as it can easily scorch the delicate fronds, leading to browning tips or entire leaves.
• It can tolerate lower light levels, but may exhibit leggy growth in insufficient light.
• Consistent light for 12-14 hours per day, either natural or supplemented with fluorescent/LED grow lights, is beneficial.

2. Water:

• Keep the soil consistently moist but never soggy. The Antenna Fern prefers regular hydration.
• Allow the top layer of soil to dry slightly between waterings, but do not let it dry out completely.
• Overwatering can lead to root rot, while underwatering can cause drooping and browning frond tips.
• Watering twice a week is a common recommendation, but adjust based on your environment and the plant’s needs.
• Consider using filtered water if your tap water is heavily chlorinated or has a high mineral content.

3. Humidity:

• High humidity is crucial for this fern. It thrives in environments with 60-70% humidity.
• Signs of low humidity include browning frond tips and edges.
• To increase humidity:
  • Mist the plant regularly (daily or every other day).
  • Place it on a pebble tray filled with water (ensure the pot is not sitting directly in the water).
  • Use a humidifier nearby.
  • It’s an excellent choice for terrariums or vivariums, which naturally provide high humidity.
  • Bathrooms are often good locations due to higher ambient humidity.

4. Temperature:

• Ideal temperatures range from 16-24°C (60-75°F).
• It can tolerate a broader range (15-35°C / 59-95°F), but avoid extreme fluctuations.
• Keep it away from cold drafts and sudden temperature changes, as these can stress the plant.
• Protect from temperatures below 10°C (50°F), as it’s a tropical fern.

5. Soil:

• Use a well-draining, rich, and slightly acidic potting mix.
• A blend that retains moisture but allows for good drainage is essential to prevent root rot.
• Options include general houseplant mix, Maranta/Calathea potting mix, or a custom blend with peat moss, coco coir, or sphagnum for moisture retention, and perlite or sand for drainage.
• It prefers neutral to acidic soil pH.

6. Fertilizer:

• Feed every 4-6 weeks during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength.
• Reduce or cease fertilization during autumn and winter when the plant enters a dormant period.

7. Repotting:

• Repot every 1-2 years, or when the plant becomes root-bound.
• Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
• Repotting is best done in early spring.

8. Pruning:

• Prune in early spring and late winter to encourage healthy growth and maintain shape.
• Remove any dead, damaged, or yellowing fronds with clean, sharp shears. This improves air circulation and overall plant vitality.

9. Propagation:

• Antenna Ferns can be propagated by division or spores.
  • Division: Carefully separate the plant into smaller sections, ensuring each section has a healthy root system. This is generally the easier method for home growers.
  • Spores: Place a mature frond in a plastic bag and allow the spores to collect at the bottom. This method is more challenging and time-consuming.

Common Issues and Troubleshooting:

• Yellowing Leaves: Often a sign of overwatering or underwatering. Check soil moisture and adjust accordingly.
• Browning Frond Tips/Edges: Typically indicates low humidity or inconsistent watering. Increase humidity and ensure consistent soil moisture.
• Drooping Fronds: Usually a sign of underwatering or temperature stress. Water thoroughly and ensure a stable, warm environment.
• Leggy Growth: Insufficient light. Move the plant to a brighter spot with indirect light.
• Pests: While generally resistant, watch out for common houseplant pests like spider mites and mealybugs. Treat with insecticidal soap or neem oil if infestations occur.

By providing these consistent care conditions, your Doryopteris cordata, or Antenna Fern, should thrive and add a unique tropical touch to your indoor plant collection.
