Watering: Water moderately during the growing season (spring to early autumn), allowing the potting medium to dry slightly between waterings. Reduce watering during the dormant period (late autumn to winter).
Potting Medium: Use a well-draining orchid mix such as bark chips or sphagnum moss. Repot every 2-3 years to refresh the growing medium.
Fertilization: Feed with a balanced orchid fertilizer diluted to half-strength every 2 weeks during the growing season. Reduce or halt fertilization during the dormant period.
