Oncidium Orchid Care: A Guide from the American Orchid Society
Oncidium orchids are a large and diverse group of orchids, with over 2,000 species and many hybrids. They are native to tropical and subtropical regions around the world, and they come in a wide variety of shapes, sizes, and colors. If you are thinking about adding an Oncidium orchid to your home, or if you already have one and you are not sure how to care for it, this guide is for you.
Oncidium orchids should be watered when the potting mix is dry to the touch. Water thoroughly, and then allow the potting mix to dry out again before watering again. Avoid getting water on the leaves or flowers, as this can cause them to rot.
Oncidium orchids should be fertilized every two weeks during the growing season with a balanced fertilizer. Reduce fertilizing to once a month during the winter months.
Oncidium orchids should be re-potted every two to three years, or when the potting mix breaks down. Use a fresh potting mix that is designed for orchids.
Pests and Diseases:
Oncidium orchids are susceptible to a number of pests and diseases, including mealybugs, scale, and root rot. If you notice any pests or diseases, treat them immediately with an appropriate pesticide or fungicide.
If your Oncidium orchid is not blooming, it may be because it is not getting enough light. Move the plant to a brighter spot, and it should start to bloom again. If the leaves of your Oncidium orchid are turning yellow, it may be because the plant is getting too much water. Reduce watering, and the leaves should turn green again.
Oncidium orchids are beautiful and easy-to-care-for plants. With a little bit of care, you can enjoy your Oncidium orchid for many years to come.
