Height (indoors): 60–150 cm (2–5 ft)
Spread: 30–60 cm (1–2 ft)
Leaf Length: 20–50 cm (8–20 in)

6. Light Requirements

Bright, indirect light; avoid direct sun to prevent leaf scorch. Tolerates medium light but growth may slow.

7. Watering Needs

Keep soil consistently moist but not waterlogged. Water when the top 2–3 cm of soil feels dry. Reduce frequency in winter. Ensure excess water drains freely.

8. Soil & Potting

Use a well-draining mix: peat moss or coco coir combined with perlite, coarse sand, and orchid bark. Repot every 1–2 years to refresh soil and divide rhizomes as needed.

9. Temperature & Humidity

Optimal temperature: 18–26 °C (65–80 °F); avoid below 15 °C (60 °F).
Humidity: High (60–80%); use a humidity tray, humidifier, or regular misting.

10. Fertilization

Apply a balanced, water-soluble fertilizer (e.g., 20-20-20) at half strength every 4–6 weeks during spring and summer. Do not fertilize in winter dormancy.

11. Maintenance & Care Level

Moderate care: sensitive to overwatering, low humidity, and pests. Wipe leaves regularly to remove dust and inspect for signs of stress.

12. Growth & Propagation

Propagate by dividing rhizomes during repotting. Separate offsets with healthy roots and replant in fresh mix. Seed propagation is rare and seeds rarely available.

13. Common Problems

Pests: Spider mites, aphids, mealybugs.
Diseases: Root rot from overwatering; leaf spot from fungal pathogens.
Symptoms: Yellowing leaves, drooping, brown leaf tips.
Remedies: Improve drainage, adjust watering schedule, treat pests with insecticidal soap or neem oil.
