Care Guide

Watering

Water thoroughly when the medium is dry, ensuring excess water drains away completely.

Fertilization

Apply a balanced, water-soluble fertilizer diluted to quarter strength.. Epiphytes require very little fertilizer; over-fertilizing can burn the delicate roots.

Banana Peel Tea:Soak chopped banana peels in water for 24 hours, strain, and dilute 1:1 with water. Use this liquid to water the plant to support root health and foliage vigor. Discard the solid peels in the compost to prevent pests and odors indoors.
Pruning
  • Trim excessively long or leggy stems to encourage branching and a fuller appearance;
  • Remove any dead, yellowing, or shriveled leaves and stems to maintain plant hygiene;
  • Propagate healthy stem cuttings by laying them on moist sphagnum moss.
