Substrate(s)

• Coarse

Care Notes

These orchids live on the forest floor, often in dead leaves or humus, yet still have the organs that would allow them to store water given unpredictable or intermittent weather conditions. They require some moisture to always be present in the soil, but not much. Water when the soil approaches dryness and don't let it dry out completely. Some growers place pots in saucers to retain water, but this may create an environment that is too wet, leading to rot.

In most areas these can be grown in the garden under trees or in sheltered locations, as long as they are reasonably protected from huge weather swings, excessive heat, and frost.

Climate

Grows at low to high elevations. Rainfall ranges from 23mm to 109mm per day, heaviest in October and lightest in January. Humidity ranges from 73% to 77%, highest in October and lowest in January. Temperature ranges from 12C to 26C, highest in May (15C to 26C) and lowest in February (12C to 23C).

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 can be sensitive to repotting though should not require repotting regularly. Repotting should be done when the mix has broken down to the point that it doesn't absorb water or holds onto water for far too long, usually the plant shows a decline in growth as well.

The mix should be free draining, with a blend of 30% inorganic ingredients such as coarse sand, gravel or perlite, mixed in with about 70% organic ingredients such as peat, leaf litter or decomposed bark. Avoid commercial potting mixes as they can vary wildly and may contain "wetting agents" that can hold onto water for loo long, causing rotting and stunted growth.

Use water retentive media such as moss to prevent roots from drying out quickly
