How to Care for the Plant
Water
Plants should be watered thoroughly with lukewarm to room temperature water every two to ten days, when the planting media is half dry
Sunlight
Oncidiums are light-loving orchids, with some able to handle direct, full sun. The vast majority will do well placed near an east, west, or south facing window with a sheer curtain to diffuse the light and provide the dappled shade these tree-growing orchids are used to.
Temperature
They thrive at 60-65° F at night, and 70-85° F during the day.
