Care Guide

Watering

Water thoroughly once a week, allowing the water to flush through the bark medium.

Fertilization

Apply a balanced, water-soluble fertilizer at quarter strength weekly.. Flush the pot with plain water once a month to prevent salt buildup from fertilizers.

Banana Peel Tea:Soak chopped banana peels in water for 24-48 hours, strain, and dilute 1:1 with water. Use as a potassium boost to encourage blooming. Avoid leaving raw peels in the pot to prevent fruit flies and fungal issues.
Pruning
  • Remove spent flower spikes by cutting them near the base with sterilized tools;
  • Trim away dead, papery, or mushy brown roots during repotting;
  • Leave old, leafless pseudobulbs intact as they store water and energy for the plant.
