General Information

The High Mountain Odontoglossum is a sympodial cool to warm growing epiphytic orchid belonging to the sub family Epidendroideae native to Colombia.

Plant Description

Sympodial. Grows to 38cm. Each new growth has numerous erect lance shaped leaves that grow to 1.5-30cm long. Pseudobulbs grow to 4-8cm

Care Notes

These orchids have a fine root system that can quickly die back if left dry for too long, but also does not like to be kept wet, so water regularly but ensure that the mix is dry before watering. 

Climate

Grows at high elevations. Rainfall ranges from 0mm to 168mm per day, heaviest in September and lightest in February. Humidity ranges from 77% to 85%, highest in October and lowest in February. Temperature ranges from 12C to 21C, highest in April (14C to 21C) and lowest in January (12C to 19C).

Watering

These orchids prefer a wet-dry cycle between waterings, they should be watered frequently but only when the moisture is approaching dryness, where the pot feels light and/or the media looks dry. Keep an eye on mounted orchids in warm weather as they may dehydrate quickly.

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 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

These plants are quite forgiving and will do well repotted ever 2-3 years. The mix should be coarse, well draining, and allow space for air to move and for roots to grow. 

Alternatively, these plants will also do well mounted to tree fern or cork slabs, or mounted to trees.

Best time for repotting or mounting the orchids is the end of winter when new growths start to appear. Avoid repotting during hot weather,

Repotting is best done annually.
