Climate

Grows at low elevations. Rainfall ranges from 165mm to 389mm per day, heaviest in November and lightest in July. Humidity ranges from 79% to 87%, highest in October and lowest in July. Temperature ranges from 22C to 31C, highest in May (23C to 31C) and lowest in January (22C to 29C).

Watering

Keep moisture levels up during hot weather as the plant is prone to dehydration Be sure to provide strong air circulation after watering to prevent fungal and bacterial infections from water sitting on leaves.

Fertiliser

Apply liquid based fertiliser per recommended directions. They can benefit from a high phosphate fertiliser leading up to flowering season, followed by a high nitrogen fertiliser when new growth appears, and a balanced fertiliser in other times. These orchids can also tolerate slow release fertiliser applied 1-2 pellets per cup (250ml) of media.

Use balanced fertiliser year round. Apply fertiliser regularly at half strength year round. Reduce fertiliser when plant is dormant.
