Care Guide

Watering

Water frequently to keep the potting medium evenly moist but not soggy.

Fertilization

Apply a weak, diluted orchid fertilizer.. Orchids are light feeders; flush the pot with pure water monthly to remove excess salts.

Aquarium Water Fertilizer:Use fresh, untreated aquarium change water to water the orchid. It provides a very mild, organic source of nitrogen that will not burn the sensitive epiphytic roots. Ensure the water is at room temperature.
Pruning
  • Sanitation: Always use sterilized cutting tools to prevent the spread of orchid viruses;
  • Foliage: Remove completely yellowed or dead leaves at the base of the ramicaul;
  • Flowers: Carefully trim away spent flower spikes without damaging the leaf tissue.
