Care Notes

These orchids like to be watered regulary, especially during warm weather, and prefer a well draining mix or also do well mounted, provided they can be watered daily or even many times a day.

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

Grows at low elevations. Rainfall ranges from 38mm to 142mm per day, heaviest in October and lightest in March. Humidity ranges from 76% to 81%, highest in October and lowest in February. Temperature ranges from 20C to 31C, highest in March (22C to 31C) and lowest in January (20C to 29C).

Watering

These orchids prefer a constant supply of moisture, with a slight drying out between waterings. Saucers can be placed under pots to retain moisture during hot weather, however the saucers should be removed or let to dry every 1-2 weeks to prevent rot. Keep an eye on the plant especially in hot weather and look for cues of under/overwatering and adjust accordingly.

Fertiliser

These orchids do not need to be regularly fertilised and roots may be sensitive to salt build-up, dying back and therefore impairing the plants growth or even killing it.

If fertilising, use half to quarter of the recommended amount of fertiliser. If they receive fertiliser as part of a collection, be sure to flush out the pots regularly with fresh water and monitor the roots by checking how much resistance is given by the plant when nudged in its pot or mount. If the plant becomes wobbly or loose, repot in fresh mix or rinse the media/mount thoroughly and do not fertilise for at least 3 months.

Apply fertiliser regularly at half strength year round.

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.
