Light

Oncidiums are more forgiving of bright, even direct, light than other popular orchids. They can cope with direct light in the morning and prefer bright or even very bright conditions. East, south or west facing windows are all suitable positions.

The leaves should be bright green as opposed to dark green or reddish green. Reddish green indicates too much light and dark green too little light.
Water

while watering allow the compost to become a little dry between waterings.They can withstand considerable drought because their large pseudobulbs act as stores. Wrinkled pseudobulbs generally indicate a lack of water. Black rotten roots are a sign of overwatering.

Temperature

Generally, the most popular oncidiums, with small yellow flowers, large pseudobulbs and strappy leaves, are those classed as intermediate to warm orchids. These require a minimum temperature ranging from 13°C to 25°C .
Humidity

Oncidiums enjoy moist air, requiring a minimum of 40-50% humidity in the immediate vicinity of the plant. Humidity should be increased with higher temperatures. The ideal humidity is 55-75%. Give as much ventilation or air movement as possible
Potting

Oncidiums do not like root disturbance and should only be repotted when either the compost becomes broken down or the pot becomes too small for the new growth. They like to be slightly under potted in a very free-draining bark-based potting media. As a general rule, repot when necessary. Every two years is ideal when the new growth is 5-7.5cm (2-3in) long.
