Oncidium Orchids also called Golden Shower Orchids or Spray Orchids are popular Indoor Orchids which are grown for their profusion of brightly colored flowers with a dominant enormous lip.
They produce a profusion of small flowers with a dominant enormous lip which partially blocks the small petals and sepals.
Oncidium orchids are magnificent bloomers where a well cared for plant can produce 6-7 branched sprays of flowers which look like a cloud of buttery butterflies which last for weeks.
The flowers in Oncidium Orchids are available in shades of yellow, red, white and pink.
Most of the Oncidiums grown indoors have large pseudobulbs and their long leaves about 2 ft long emerge from the pseudobulbs. The roots are a mass of thin white roots.
Oncidium is a genus of orchids distributed across South America, Central America and West Indies. They usually occur in seasonally dry areas.
The genus name Oncidium is derived from the Greek word onkos meaning "swelling" in reference to the callus at the lower lip.
The genus name is abbreviated as Onc. in horticultural journals. Many hybrids and cultivars of Oncidium Orchids have been developed.

Oncidium Orchid blooms best when it is pot-bound. Repot your Oncidium Orchid only when growth begins to suffer.
Repot your Oncidium Orchid when the orchid has outgrown its pot and the new growth reaches out over the edge of the pot or when the soil has broken down completely. Basically repotting your Oncidium Orchid every 2-3 years should be adequate.
Repot your Oncidium Orchid only when new growth begins, shortly after blooming is over. Do not repot an orchid that is in flower as it may shorten the flowering season.
Use a pot with proper drainage holes or slits as the roots of your Oncidium Orchid need good air circulation.
The pot for your Oncidium Orchid should be only 1 size larger than the previous one. Use loose, free-draining bark soil for your Oncidium Orchid.
When repotting your Oncidium Orchid, shake off excess soil and trim off any dried and shrivelled pseudobulbs.
The large Oncidium Orchid (ones with about 6 or more pseudobulbs) should be divided, (leaving 3 shoots on each section) to propagate new plants.
Pruning Oncidium Orchid is easy. Remove dead and diseased leaves by cutting them at the base with sharp scissors or a knife.
When flowering is over for your Oncidium Orchid, cut the flower stalk 1 in. above the 3rd node from the bottom to encourage more flowers.
Gently split the Oncidium Orchid rhizome into sections while ensuring there are at least 3 shoots on each section.
Seperate the roots attached to each division from the mother Oncidium Orchid root-ball.
Remove the old potting soil attached to the Oncidium Orchid section roots and place each section in the center of the pot.
Bury the roots of the Oncidium Orchid section in the soil while ensuring that the bottom of the pseudobulb is level with the top of the soil.
The best pot for the Oncidium Orchid section should be about 1-2 in. larger than the pseudobulb.
Ensure the pot has enough drainage holes and slits to prevent root-rot of your Oncidium Orchid section.
Place the set up in a shaded place until Oncidium Orchid sections have established their own roots.
Water the new Oncidium Orchids lightly to enhance root development. Stake each newly repotted plant to prevent it from toppling over.
Oncidium Orchids naturally produce "baby" orchids called "keiki" which normally appear on an old or new flower spike. Keikis are identical copies of the parent plant.
Keiki growth can be triggered by prolonged exposure to high temperature during the final phase of spike growth.
The keiki can be detached from the mother Oncidium Orchid when about one year old when it has developed 2-3 leaves and 1-3 in. long roots.
Pot the Oncidium Orchid keiki in fresh potting medium and direct the roots of the Oncidium Orchid keiki downwards and provide support for the keiki to prevent it from toppling over.
Place the set up in a well-lit, shaded place and mist the keiki regularly to maintain a humid enviroment.
Allow the new Oncidium Orchid to be well established before transplanting it afte which routine care can begin.
