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

hot-growing-orchids 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 6C to 28C, highest in April (17C to 28C) and lowest in January (6C to 22C).

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.

Fertiliser

These plants thrive on fertiliser, especially during periods of growth. Liquid fertiliser can be applied year round at the recommended strength, augmented with manure pellets or other quickly degradable fertiliser, applied away from the base of the plant, during periods of strong growth. Slow release pellets can also be applied year round at the rate of 2-3 pellets per cup (250ml) of media.

They can benefit from a high phosphate fertiliser leading up to flowering season, and by a high nitrogen fertiliser when new growth appears. 

Use balanced fertiliser during Spring and Summer. Use a high Nitrogen fertiliser during Spring and Summer. 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.
