Oncidium aspecum

Native to: Peru

General Information

Oncidium aspecum is a small sympodial cold to warm growing epiphytic or terrestrial orchid belonging to the sub family Epidendroideae native to Peru.

Plant Description

Sympodial. Each new growth has numerous lance shaped leaves that grow to 3-19cm long. Pseudobulbs grow to 2-6cm

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 3mm to 69mm per day, heaviest in August and lightest in January. Temperature ranges from 6C to 22C, highest in April (10C to 22C) and lowest in January (6C 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.

Potting

These plants can be sensitive to repotting though should not require repotting regularly. Repotting should be done when the mix has broken down to the point that it doesn't absorb water or holds onto water for far too long, usually the plant shows a decline in growth as well. Repotting is best done after the growing season when the plant has died back.

The mix should be free draining, with a blend of 30% inorganic ingredients such as coarse sand, gravel or perlite, mixed in with about 70% organic ingredients such as peat, leaf litter or decomposed bark. Avoid commercial potting mixes as they can vary wildly and may contain "wetting agents" that can hold onto water for loo long, causing rotting and stunted growth.
