Oncidium
(The Dancing Lady)
Oncidiums are a member of the Odontoglossum tribe. The genus “Oncidium” is one
of the most interbred orchid and have offspring of more than 50 new genera (types) in
their Alliance. Nicknamed “Dancing Lady”, their flowers have small petals with a large
lip that appears to be a yellow, flowing ball gown. Their multiple branches of tiny
flowers “dance” with little air movement.
Commonly found in florist arrangements, Oncidiums are among the easiest of orchids to grow and
are moderate growers. Their flower spikes develop on the mature new growth of the plant and
typically bloom in the fall.
How to keep your Oncidium healthy
Light: Bright to moderate indirect light. Ideally, early morning indirect light as in a Southern facing
window. East and West facing windows are good too, provided direct sun is not on the orchid. Early
morning and evening sun is OK. The foliage should be medium green color, indicating the orchid is
getting enough light to flower. Oncidiums thrive with good air circulation.
Temperature: The ideal temperature during the day is 80°F to 94°F. Some Oncidiums can tolerate
higher temperatures to 98°F for short periods of time. Night temperatures can range from 50°-60°F at
night.
Watering: Watering should be done in the morning hours. You can water heavy overhead, or soak
potted orchid in the sink for ten minutes. In cold areas the water temperature should not be below
45°F. Watering with ice cubes in NOT recommended. Water is an essential nutrient for plant
development. In moderate light water one to two times a week in winter, and two to three times a
week in summer. This may need to be increased in bright light conditions. When in doubt, check the
bottom of the pot, if it looks dry, then water..
Feeding: Oncidiums are moderate feeders and require fertilizing every third watering. Use Gubler
Pro Blend Orchid Food 19-8-16. This formula is exactly what we use to grow our Oncidiums. By
feeding every third watering, you will be feeding more during the longer days of summer when the
orchid has more light to grow, and less in the shorter days of winter.
Repotting: Should be done once every 12 to 18 months. It is best to repot after the Oncidium is
done flowering. Plants that have overgrown their container should be potted into a suitable container
the next size larger. Make sure the container your choose had good bottom drainage, this will allow
the roots of your Oncidium to get the air they need. We do not recommend however, pots with slits
on the side. Transplant using Gubler Orchid Grow Mix- Fine Grade for all container sizes.
What to expect: The small, yellow or brownish, flowers of the Oncidium, with their branching spikes,
have been popular for decades. While the Oncidium genus itself has flowers that are one quarter to
two inches in diameter. Flowers should last approximately four to six weeks, depending on your
growing conditions. The “Shari Baby” hybrid also has small flowers, but produces a wonderful
“chocolate” fragrance. Oncidiums are excellent for the beginner, and will have long lasting appeal.
