Oncidium orchids have been nicknamed the Dancing Lady Orchids, and once you see a flower, you know why. Their blooms resemble a tiny dancer with a colorful outfit. Oncidiums are a relatively small plant and may bloom when planted in a smaller pot.
ONCIDIUM ORCHID CARE
Oncidium orchids need fairly bright light, especially during the winter months when a southern exposure would be ideal. Shading from the bright Colorado sun will be required throughout most of the year for all orchids. A sheer curtain or translucent window would be ideal.
Water Oncidium orchids depending on the plant’s growth. When in full growth or flowering season, water should be applied as soon as the plant begins to dry out. The plant’s weight easily determines this. Some Oncidium orchids will need rest for a time after flowering and should be watered sparingly until new growth appears. Watch your plant for signs of its needs. If the bulbs begin to shrivel, apply more water.
Oncidium orchids like the humidity around 50-60% relative humidity. Group plants together or place them on a tray filled with gravel and partially filled with water to increase humidity levels. If the humidity in your home is below 50%, both you and your plants will benefit from a rise in levels.
The majority of Oncidium orchids will grow well with intermediate temperatures ranging from around 60 degrees F at night and 70-85 during the day. As with all plants, lower night temps are always beneficial.
Oncidium orchids are not heavy feeders, and foliar feeding has produced excellent results. Use a balanced 20-20-20 solution during the spring and summer months of active growth. Withhold feeding during periods of slow growth, usually during the winter months.
POTTING ONCIDIUM ORCHIDS
Repotting Oncidium orchids are usually best done in the early spring as new growth begins to emerge. Use as small a pot as it will hold the plant. Repot at least every two years. Ensure that your pot and potting medium have excellent drainage as oncidium roots do not light to stay wet.
