Oncidiums are adaptable plants that can be easily grown in an east or west window in temperate areas or on a screened patio in the warm south. Like all orchids they require a certain amount of humidity and abundant air movement. Most Oncidiums also require enough light to thrive and flower reliably. Low light areas can be supplemented with grow lights if necessary. Most of these orchids prefer the same intermediate temperatures as people.
Oncidiums like to dry out between waterings.
This does not mean that you should not water these orchids, it just means that they need to dry out between waterings. Choice of potting material can help if you like to water your plants often. This tendency of wanting to dry out makes these carefree orchids a perfect choice for people with busy schedules. Oncidiums should be potted into an orchid mix. Fertilize every two weeks while in growth, contact one of Campbell's Nursery Professionals for available orchid fertilizers.
