Care Guide

Watering

Water thoroughly 1-2 times a week, allowing the roots to dry slightly between waterings.

Fertilization

Apply a balanced, water-soluble orchid fertilizer at quarter strength weekly.. Orchids are light feeders; the 'weakly, weekly' approach prevents root burn from salt buildup.

Banana Peel Tea:Soak chopped banana peels in water for 24-48 hours. Strain the liquid and dilute 1:1 with fresh water. Use this to water the orchid to promote blooming. Discard the solid peels in compost; do not leave them on the orchid bark as they will mold and cause root rot.
Pruning
  • Use sterilized shears to cut back spent flower spikes near the base to redirect energy to new growth;
  • Remove dead, papery, or mushy brown roots during repotting;
  • Leave healthy, green pseudobulbs and canes intact, as they serve as water and energy reservoirs for the plant.
