Climate

Grows at low to high elevations. Rainfall ranges from 5mm to 175mm per day, heaviest in September and lightest in February. Humidity ranges from 63% to 81%, highest in October and lowest in March. Temperature ranges from 15C to 30C, highest in April (19C to 30C) and lowest in January (15C to 25C).

Watering

These orchids are sensitive to excessive watering and should only be watered when they look thirsty. Water infrequently and ensure that the roots are dry before watering. Keep an eye on them especially during hot weather as overwatering can lead to rot, whereas underwatering may result in wilting or shriveling, which while unattractive, will not kill the plant.

Potting

These plants are quite forgiving and will do well repotted ever 2-3 years. The mix should be coarse, well draining, and allow space for air to move and for roots to grow. 

Alternatively, these plants will also do well mounted to tree fern or cork slabs, or mounted to trees.

Best time for repotting or mounting the orchids is the end of winter when new growths start to appear. Avoid repotting during hot weather,
