Climate
Grows at low elevations. Rainfall ranges from 114mm to 638mm per day, heaviest in December and lightest in May. Humidity ranges from 77% to 84%, highest in December and lowest in August. Temperature ranges from 23C to 31C, highest in May (24C to 31C) and lowest in January (23C to 27C).
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.
Keep moisture levels up during hot weather as the plant is prone to dehydrationFertiliser
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.
