yellow oncidium orchid Description
Oncidium is a type of orchid. In the natural environment, these beautiful flowers are found in the tropics of South America: they prefer the tops of rocks. They can also be found in savannas or semi-deserts.
The description of each species differs significantly depending on the color of the leaves, flowers, length of the roots.
All representatives of the genus grow on trees or stones, absorbing moisture and nutrients through aerial roots (epiphytes). In some oncidiums, they are so long that they hang from the pot.
Thick, green roots both sink into the substrate and grow above the trunk along with the leaves. Some of them should always be open to absorb moisture.
Oncidium has the so-called bulbs – thickenings at the roots in the form of a club, from which the leaves begin to grow.
Peduncles are erect or hanging in a long train. The color of the buds belongs mainly to one color scheme: brown-yellow or orange.
The flowers are shaped like flying firebirds or butterflies. The petals differ from each other in size, the lower one is unpaired and the widest.
Oncidium can bloom twice a year, retaining its attractiveness for up to a month. Inflorescences are also used by florists to make bouquets, since after cutting the corollas do not lose their beauty.
Interesting! In addition to being decorative, the flowers exude a pleasant fragrance.

yellow oncidium orchid Transplant after purchase and during further growing season
The first thing you need to pay attention to is the condition of the flower in the store. It must have more than 3 pseudobulbs, since only in this case the flower could form buds without artificial stimulation.
The roots are light green in color. Since most orchids are sold in transparent pots, this is easy to see.
The soil in the container should not be dry or, conversely, sink in water. Leaves of natural color without brown spots and damage.
After the purchase, the oncidium needs a transplant if the roots are too crowded in the pot or the condition of the substrate is poor.
Important! The plant is sensitive to root damage, so it should not be transplanted unless absolutely necessary.
The yellow oncidium orchid transplant is carried out as follows:
- The plant is turned over and shaken out of the pot. Better to hold it by the base.
- The roots are cleaned of the old soil, if it has plaque, mold, lumps or rot.
- Diseased roots are cut off with a sharp knife in places where they are still green.
- While the pot and soil are being prepared, the plant should be placed in water at room temperature for 10-15 minutes.
- A new container needs to be taken more than the previous one by a couple of centimeters.
- A layer of flower drainage is poured at the bottom, and the same layer of new soil is poured on top.
- The plant is taken out of the water, the places of cuts are sprinkled with charcoal powder.
- The oncidium is installed so that the large (old) bulbs are oriented towards one edge, and the new ones towards the center, the voids are covered with a substrate.
Important! Pseudobulbs are left above the surface.
At the end, be sure to check the transplanted flower for stability and, if necessary, install props.
yellow oncidium (dancing lady) orchid Care
Oncidium is considered an unpretentious indoor flower, especially its hybrid varieties. Care at home for the plant comes down to observing the necessary microclimate. For a detailed Yellow oncidium orchid care guide. Here below we also look at short care.
Oncidium tolerates temperatures well from 15 ° C in winter to 27 ° C in summer. At the same time, temperature fluctuations during the day are more important for almost all species. A change of even 5 degrees can be detrimental to flowers.
Air humidity is not the main microclimate factor for oncidiums. Well, when this figure is in the range of 40-70%. In the summer heat and the absence of an air conditioner, it is useful to spray the plant with water at room temperature. If this is not possible, then a container with liquid is placed next to the flower or wet expanded clay is poured into the pan.
In winter, when the air from the radiators is dry, it is useful to give the plant a warm shower 1-2 times a week. The main thing is not to spray the flowers themselves and take breaks for a dormant period at temperatures below 18 ° C.
In addition to artificially increasing humidity, you need to ventilate the room daily to freshen the air. At the same time, the flower pot is removed away from the window. The procedure improves the microclimate, plus it is a good prevention of fungal diseases and mold.
Oncidium needs a lot of diffused light. It is better to protect the flower from direct sunlight so as not to get brown spots on the leaves.
Indirectly, the amount of light is indicated by the color of the leaves. They become dark and dense when the flower needs additional illumination. With the pallor of the leaf plates, the plant must be set aside from the window.
Oncidium can look good even in low light, but still not bloom. Therefore, if the plant stands for a long time without flowers, then you first need to adjust the amount of light.
Substrate for yellow oncidium (dancing lady) orchid
Oncidium needs soil, like orchids. The prepared substrate is sold in stores. Its main component is tree bark in large pieces. Even for self-preparation of the soil, you will need to purchase it. The substrate mixes sphagnum, peat and bark in equal parts. Charcoal is added to prevent fungal infection.
The watering regimen depends on the stage of flower development. If the growth of leaves begins from a new pseudobulb, then regular moisturizing is required. To do this, the plant is watered from a long watering can so that water does not fall on the leaves.
A more natural way for orchids is to absorb moisture through the wide holes in the bottom of the pot. The plant is placed in a basin of water at 2/3 of the height of the pot for half an hour.
With any method, 15 minutes after watering, excess liquid is drained from the pan. The procedure during the period of active growth is carried out 3 times a week.
When the formation of a new pseudobulb begins, watering is reduced to weekly: this inhibits the growth of the bush and stimulates the laying of flower buds.
Top dressing is carried out with ready-made mineral fertilizers for orchids the liquid is diluted with water in half the dose indicated on the package. Fertilizers are applied throughout the period of leaf growth and flowering.
Feeding should be stopped after the peduncle wilts and pseudobulbs begin to form.
Oncidium pruning may be needed only after the peduncle has withered. If it turns yellow, it is cut at a distance of about 5 cm from the base.
Transplantation is carried out only when the roots fill the entire volume of the pot. The flowerpot is selected with large drainage holes at the bottom.
In the new container, the plant is positioned so that the first (oldest) bulb is at the edge, and from the center there is a distance for growing in width.
Advice! The pot should be bought wide and high in order to cover the bottom with a drainage layer.
yellow oncidium (dancing lady) orchid Diseases
Orchids are quite vulnerable to pests. Mealybug, scale insect or tick appear on the leaves . Insects must be mechanically removed with cotton wool and an alcohol solution or soap. Then the entire plant and the soil surface are sprayed with an insecticidal solution, such as Aktara.
The reason why the oncidium dries the peduncle may be that it is covered with leaves from the light.
When the plant is kept in cold or frequent drafts, root rot of a bacterial or fungal nature may appear. The constant stay of the roots in too wet soil also leads to the disease .
The damage is indicated by small brown spots on the leaves and roots. In the early stages, you can save the plant by removing the damaged parts and rearranging the flower in a warm, ventilated place.
yellow oncidium (dancing lady) orchid Propagation methods
It is easy to propagate the oncidium by dividing the bush.
Yellow dancing lady orchid propagation by division of the bush
You can divide a bush with at least 6 bulbs. In this case, half is separated from it, transplanted into another pot and a dry substrate. If necessary, during reproduction, adjacent bulbs are cut with a sharp knife, and the cuts are sprinkled with charcoal.
Advice! A young plant does not need to be watered for the first week so that the process of decay does not begin.
The best time for planting is the beginning of spring.
yellow oncidium Propagation by Pseudobulb jigging
Pseudobulbs in oncidium separate themselves along with the roots. To plant them, you only need to carefully divide the bush according to the number of new shoots and plant them in separate pots.
