Substrate(s)

• Coarse
• Medium
• Bark
• Spaghnum Moss

Care Notes

This orchid goes into a dormancy phase during winter, during this phase it is best not to provide water unless the plant is starting to look thirsty. The lack of water increases the chance of flowering in spring, and also reduces the likelihood of any rot forming. Do not resume watering until new growth has appeared and is growing strongly.

Often a period of intense growth occurs after dormancy. During this time the amount of light, water and fertiliser the plant receives will directly impact the amount of growth that occurs during this time, and in the case of seedlings, will reduce the time required to reach maturity.

It's recommended to heavily reduce the water amount at the middle to end of autumn to trigger dormancy. Leaves on older bulbs will begin to drop during this time while the newer bulbs continue to mature until terminal leaves appear at the tip of the pseudobulbs.

Repotting can be done any time of the year though it's best to do it in early spring when new growth is appearing as this also means new roots will appear to help the plant anchor into the new media and offset any damage to established roots during the repotting process.

 

Climate

These orchids thrive in humid, cool, shady conditions with good airflow, they will be found under dense forest canopies where they will receive moderate sun exposure throughout the year.

When cultivated they will thrive in a cool, sheltered environment such as a shaded greenhouse, or if grown in cooler climates they can be grown in the garden in areas where they are protected from frost and receive shade throughout the year, though they may be able to tolerate some morning sun during winter.

Grows at high elevations. Rainfall ranges from 5mm to 239mm per day, heaviest in July and lightest in February. Humidity ranges from 40% to 79%, highest in August and lowest in April. Temperature ranges from 6C to 29C, highest in May (15C to 29C) and lowest in January (6C to 22C).

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 dehydration

Fertiliser

dormant-medium-demand-orchid Use balanced fertiliser during Spring and Summer. Apply fertiliser regularly at half strength year round. Use a high Nitrogen fertiliser during Spring and Summer. Use a high Phosphorous fertiliser during Summer.

Potting

Due to the growth nature of these plants they are best mounted onto cork, tree fern slabs, or even trees if the climate suits. Water regularly especially in hot weather.

Use water retentive media such as moss to prevent roots from drying out quickly This plant does very well in baskets or suspended pots This plant does well mounted to Tree trunks or Fern slabs. Repotting is best done annually.
