-
Temperature:
- Summer: Daytime temperatures of 27-29°C and nighttime temperatures of 19-20°C, with a daily variation of 7-9°C.

Substrate and Growing Media:
- Grow in hanging pots or slatted baskets filled with loose, coarse, quick-drying media.
- Use a small amount of charcoal, wine corks, or large cork bark pieces to keep the plant in place until roots secure themselves.
- Avoid cutting the roots; allow them to grow and hang freely to prevent developmental setbacks.

- Reduce watering when new growths mature in late autumn.
-
Fertilizer:
- Fertilize weekly during active growth with 1/4-1/2 of the recommended orchid fertilizer dose.

-
Rest Period and Repotting:
- During winter, reduce watering significantly but do not let the plant dry out completely.
- Light morning misting every few days suffices, especially in high humidity.
- Reduce or eliminate fertilization until new growth appears and spring watering resumes.
