Plant Description
Grows to 12cm. Each new growth has numerous erect tongue shaped leaves that grow to 0.5-11cm long. Pseudobulbs grow to 0.5-1.5cm
Climate
Grows at low to high elevations. Rainfall ranges from 28mm to 201mm per day, heaviest in June and lightest in February. Humidity ranges from 80% to 84%, highest in September and lowest in January. Temperature ranges from 9C to 26C, highest in July (16C to 26C) and lowest in January (9C to 20C).
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
Be sure to flush out excess fertiliser by running water through the media regularly year round.
