Climate

Grows at low to high elevations. Rainfall ranges from 3mm to 224mm per day, heaviest in September and lightest in December. Humidity ranges from 59% to 82%, highest in September and lowest in March. Temperature ranges from 9C to 34C, highest in April (22C to 34C) and lowest in January (9C to 27C).

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.

Be sure to flush out excess fertiliser by running water through the media regularly year round. This plant is sensitive so apply fertiliser sparingly at one quarter recommended strength or less. Use a high Nitrogen fertiliser year round. Use a high Phosphorous fertiliser during Summer.

Potting

Due to the growth nature of these plants they are best mounted onto cork, tree fern slabs, or even trees if the climate suits. Water regularly especially in hot weather.

This plant does well mounted. Repotting is best done annually.
