Native to: Panama
General Information
Maduro's Oncidium is a sympodial cool to warm growing epiphytic orchid belonging to the sub family Epidendroideae native to Panama. It is named after the Panamanian Orchid Enthusiast Current.
Plant Description
Sympodial. Each new growth has numerous elliptic oblong shaped leaves that grow to 1.5-35cm long. Pseudobulbs grow to 2.5-11cm
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
These orchids grow in cool climates, at low altitudes, in cool plains, forests or coastal scrub.
They are forgiving of humidity variances as long as temperatures are kept on the cool side. They can do well outdoors in the garden in cool and temperate areas, though it is important that they are protected from warm dry winds. They can enjoy morning sun especially in winter but will need protection from the hot sun in the afternoon and during summer. With some acclimatisation they may be able to receive more sun.
Grows at low to high elevations. Rainfall ranges from 71mm to 180mm per day, heaviest in August and lightest in March. Humidity ranges from 82% to 94%, highest in May and lowest in April. Temperature ranges from 13C to 23C, highest in June (16C to 23C) and lowest in January (13C to 21C).
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
Reduce fertiliser when plant is dormant.
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,
