🪴 Indoor Care Guide
🌤️ Light
- Ideal: Bright, indirect light.
- Avoid direct sunlight — it can scorch the fronds.
- Tolerates lower light but may grow more slowly.
- East or north-facing windows are perfect.
💡 Tip: If you only have bright south or west windows, use sheer curtains to diffuse the light.
🌡️ Temperature & Humidity
- Temperature: 60–80°F (16–27°C)
- Avoid cold drafts or sudden temperature drops.
- Humidity: Loves high humidity!
- Mist the leaves regularly, or
- Place the pot on a pebble tray with water, or
- Use a humidifier nearby.
💧 Tip: If the fronds turn brown and crispy at the tips, the air is likely too dry.
💧 Watering
- Keep soil evenly moist, but not soggy.
- Water when the top inch of soil feels slightly dry.
- Always use pots with drainage holes to prevent root rot.
🪣 In winter, water less frequently, but don’t let it dry out completely.
🌱 Soil
- Use a loose, well-draining mix.
- Ideal mix:
- 2 parts peat or coco coir
- 1 part perlite or orchid bark
- 1 part compost or loam
🌾 Fertilizer
- Feed monthly during spring and summer with a balanced, diluted liquid fertilizer (½ strength).
- No need to fertilize in winter when growth slows.
✂️ Pruning & Maintenance
- Trim off dead or yellowing fronds at the base.
- Wipe leaves occasionally with a damp cloth to remove dust.
- Repot every 2–3 years or when roots start to crowd the pot.
🪴 Propagation
- By division during repotting:
- Gently remove the plant from its pot.
- Separate the root ball into smaller clumps (each with fronds and roots).
- Replant each section in its own pot.
- Keep moist until new growth appears.
