Care Notes

These orchids like to be kept on the dry side, but may need to be watered daily during warm weather, and prefer a well draining mix or also do well mounted, provided they can be watered regularly.

These are quite a forgiving orchid, there are no special requirements to get this orchid to flower, just good care and consistent conditions. Larger plants may be more fussy and can react poorly to change; a poorly timed repotting, a pest infection or an unusually hot day can set them back for a couple of years. However, even plants that have been treated poorly can thrive, and if they are set back they often recover much stronger then they would otherwise be.

Climate

The orchids are well adapted for hot weather, accompanied by sporadic, unpredictable rainfall and a generally dry climate. They can tolerate a lot of neglect as they are quite used to it, however they can be prone to underwatering and may collapse in cold, wet weather.

For this reason it's best to dedicate a sheltered, protected area for them where the watering can be controlled, such as a corner of a greenhouse or in a sheltered balcony. They can also do well hung near the roof of a shadehouse or sheltered greenhouse where they receive the extra heat but not as much water as other plants. 

Grows at low to high elevations. Rainfall ranges from 8mm to 292mm per day, heaviest in September and lightest in January. Humidity ranges from 58% to 83%, highest in August and lowest in March. Temperature ranges from 12C to 34C, highest in April (22C to 34C) and lowest in January (12C to 27C).

Watering

These orchids gather most of their water from their aerial roots, which should be sprayed regularly or kept in a humid environment; roots exposed to dry air that receive no water will die back. On that same note, roots that are inside a pot surrounded by media may also die back, with new roots growing from the stem away from the pot.

If outdoors, a misting system aimed at the roots that turns on regularly will help them grow, otherwise if indoors placing the roots inside a vase or pot with no media along with regular spraying should give them the moisture they need.

Fertiliser

Apply liquid based fertiliser per recommended directions. They can benefit from a high phosphate fertiliser leading up to flowering season, followed by a high nitrogen fertiliser when new growth appears, and a balanced fertiliser in other times. These orchids can also tolerate slow release fertiliser applied 1-2 pellets per cup (250ml) of media.

Apply fertiliser regularly at half strength year round. Use a high Nitrogen fertiliser during Spring and Summer. Use a high Phosphorous fertiliser during Summer.

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,

This plant does very well in baskets or suspended pots Repotting is best done annually.
