Is Oncidium easy to grow? Teaching you the correct cultivation method
Oncidium, also known as dancing lady orchid, dancing girl orchid, and golden butterfly orchid, originated in tropical rainforests. Its flowers come in diverse colors and have a long blooming period. Next, let us take a look at how to grow Oncidium.
Oncidium, also known as dancing girl orchid, golden butterfly orchid, and tubercled orchid, is the general name for plants in the genus Oncidium in the orchid family. There are more than 750 native species of this genus worldwide, while the commercially used varieties in all their diverse forms are mostly hybrids. The plants are light and elegant, with slender, drooping flower stems, and the flowers are strange and lovely, shaped like flying golden butterflies and full of movement. They are one of the world's important potted flower and cut flower types.
Oncidium is native to the United States, Mexico, Guyana, and Peru. The original-leaf type (also called hard-leaf type) Oncidium prefers warm environments, while the thin-leaf type (also called soft-leaf type) and sword-leaf type Oncidium prefer cool climates.
Oncidium has 1-3 leaves and can be divided into thin-leaf species, thick-leaf species, and sword-leaf species. Generally, one pseudobulb bears only 1 flower stem, though some robustly growing ones may have 2 flower stems. Some species have only 1-2 flowers per flower stem, while others can reach hundreds, such as the small-flowered species used as cut flowers, where one stem has dozens of flowers, and several stems have from one hundred to several hundred flowers. Their flowers are brightly colored, shaped like flying golden butterflies, and also like dancing girls, hence the names golden butterfly orchid or dancing girl orchid.
Oncidium flower colors are mainly yellow and brown, and also include green, white, red, and magenta. Their sizes range from extremely small, such as miniature Oncidium, to extremely large, with flower diameters reaching more than 12 cm. The flower structure is extremely special: the sepals are equal in size, and the petals and dorsal sepal are also almost equal or slightly larger; the lip is usually three-lobed, either large or small, fiddle-shaped, and at the base of the middle lobe there is a ridge-like protrusion, with small raised spots on the ridge, quite peculiar, hence the name tubercled orchid.
The key cultivation points for Oncidium are:
1. For cultivation materials, in hot and humid places use tree fern, boards and pots made from non-oily broadleaf hardwood, etc., while in dry climates, use sphagnum moss, fern roots, moss, etc. to plant in porous pots.
2. Daily management: Oncidium generally has relatively low environmental requirements, but the winter temperature should not be lower than 15°C, and air humidity should be around 80% throughout the four seasons. In spring, summer, and autumn it needs a semi-shaded environment; in winter it can be given sufficient sunlight, but never expose it to the scorching sun of midsummer.
Oncidium propagation mostly uses the division method. Generally, do not water immediately after division; when slightly dry, spray some water on the leaf surface, wait until new roots grow and then water, then spray some balanced fertilizer, but the concentration must not be too high, generally 0.6% to 0.8%. During care, do not water too much, as this easily causes root rot, and pay attention to ventilation and light transmission. If there are diseased plants, they should be destroyed in time and sprayed with some fungicides. During the flowering period, temperature and humidity should not be too high or too low, as this will affect flower longevity, shorten the flowering period, and even cause bud drop or early withering.
[Temperature management] During the seedling recovery stage, the daytime temperature is 25-28°C and the nighttime temperature is 23-25°C. New roots sprout and grow quickly. After new roots grow, the temperature can be appropriately relaxed, but maintaining the above temperatures is conducive to orchid seedling growth. After the pseudobulbs mature, when the day/night temperatures are (26-29°C)/(23-25°C), Oncidium can shift from vegetative growth to reproductive growth.
[Humidity management] Relative humidity should be controlled at 60%-80%. For newly planted small seedlings, humidity should be around 80%. Humidity should not be too high or too low: too high makes them prone to disease infection, and too low is unfavorable for orchid growth. In hot summer, water should be sprayed on the ground around the plants, on benches, and on leaves to increase air humidity, and good ventilation must also be maintained, otherwise it will lead to poor plant growth and easy rotting of pseudobulbs.
