Substrate(s)

Climate

Grows at low to high elevations. Rainfall ranges from 94mm to 262mm per day, heaviest in August and lightest in February. Humidity ranges from 79% to 85%, highest in April and lowest in January. Temperature ranges from 21C to 30C, highest in February (21C to 30C) and lowest in January (21C to 29C).

Watering

These orchids prefer a constant supply of moisture, with a slight drying out between waterings. Saucers can be placed under pots to retain moisture during hot weather, however the saucers should be removed or let to dry every 1-2 weeks to prevent rot. Keep an eye on the plant especially in hot weather and look for cues of under/overwatering and adjust accordingly.

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.

Potting

Repotting is best done in a pot the same size or only slightly larger than the previous one.
