Soil and Potting
- Use a chunky, airy mix: compost, bark, perlite
- Choose a pot with multiple drainage holes

Browning Leaf Tips
- Usually caused by low humidity or hard tap water
- Fix: Use filtered water, boost humidity
Yellowing or Drooping Fronds
- Often due to overwatering or compacted soil
- Fix: Improve drainage, let top layer dry slightly before watering
Fungal Spots or Rot
- Caused by stale air or wet foliage
- Fix: Improve airflow, avoid wetting fronds, use copper fungicide if needed
