Prefers 18–26°C avoid sudden temperature drops.
Use a humidifier in drier environments.
Soil and Repotting
Use a well–draining mix with orchid bark, perlite, and sphagnum moss.
Repot every 2–3 years to refresh soil and allow root expansion.
Choose a pot with drainage holes to prevent water buildup.
Avoid oversized pots, which hold excess moisture.
Fertilizing
Apply diluted liquid fertilizer every 4 weeks during active growth.
Use a balanced or bloom–boosting formula.
Avoid excessive fertilization to prevent leggy growth.
Occasional foliar feeding enhances leaf health.
