Climate

These orchids grow in cool climates, at low altitudes, in cool plains, forests or coastal scrub.

They are forgiving of humidity variances as long as temperatures are kept on the cool side. They can do well outdoors in the garden in cool and temperate areas, though it is important that they are protected from warm dry winds. They can enjoy morning sun especially in winter but will need protection from the hot sun in the afternoon and during summer. With some acclimatisation they may be able to receive more sun.

 

Grows at low to high elevations. Rainfall ranges from 13mm to 432mm per day, heaviest in July and lightest in February. Humidity ranges from 68% to 87%, highest in September and lowest in April. Temperature ranges from 16C to 29C, highest in April (19C to 29C) and lowest in January (16C to 26C).

Fertiliser

These plants thrive on fertiliser, especially during periods of growth. Liquid fertiliser can be applied 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 that occurs in the middle of the growth season.

Do not fertilise during the dormant period. Avoid using slow release fertiliser that breaks down for longer than 3 months, if using apply only after dormancy when new shoots have developed noticably, applied 4-5 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. Fertiliser can be applied heavily year round. Use a high Nitrogen fertiliser during Spring and Summer. Use a high Phosphorous fertiliser during Summer.

Potting

This plant does well mounted. Repotting is best done annually and in Spring.
