Care Guide

Watering

Keep potting medium slightly moist during active growth; mist foliage occasionally to boost humidity

Fertilization

Diluted balanced orchid fertilizer every 2 weeks. Cease fertilization entirely during winter dormancy to avoid nutrient buildup

Banana peel compost tea:Compost banana peels for 4–6 weeks until fully decomposed; dilute 1:20 with water for root drench to avoid burning sensitive orchid roots
Pruning
  • Remove spent flower spikes after blooming to redirect energy to pseudobulb development
  • Trim yellowing or dead leaves at the base to maintain plant health and airflow
  • Divide overcrowded pseudobulbs during late spring repotting to prevent overcrowding
