Prefers bright, indirect light.
 
Avoid direct sun, which can scorch the fronds.
 
Can tolerate semi-shade, though growth may slow.


 → Watering

 
Keep soil consistently moist but not waterlogged.
 
Use filtered or rainwater to prevent leaf spotting from minerals.
 
Ensure good drainage to prevent root rot.


 → Humidity and Temperature

 
Requires high humidity (60-80%) to thrive.
 
If air is dry, use a humidifier or group with other moisture-loving plants.
 
Prefers temperatures between 18-28°C. Avoid exposure to cold drafts or temperatures below 15°C.


 → Soil and Pot Choice

 
Best in well-draining, organic-rich soil (peat, perlite, and compost mix).
 
Use a deep, well-draining pot with multiple drainage holes.
 
Avoid excessively large pots that retain too much moisture.


 → Repotting and Fertilizing

 
Repot every 2-3 years to refresh the soil.
 
Fertilize monthly with a balanced liquid fertilizer, diluted to half-strength.


 → Pruning and Propagation

 
Trim yellowing or dead fronds to encourage new growth.
 
Propagate by division during repotting or by spores.


 → Semi-Hydroponics and Hydroponics
Can adapt to semi-hydroponic setups in LECA or perlite, as long as moisture is carefully regulated.
