How to Cultivate Oncidium Orchids
The article discusses how to cultivate Oncidium orchids and the methods and precautions for growing this type of green plant, so let's follow the editor to explore the specific content!
Oncidium orchids, also known as吉祥兰 (auspicious orchid), 跳舞兰 (dancing orchid), and 舞女兰 (dancing girl orchid), are a type of orchid that are cultivated in both southern and northern China, with the southern regions having more cultivation. Many orchid enthusiasts enjoy growing Oncidium orchid potted plants at home, but this plant is not easy to care for and rarely blooms, mainly because the proper care methods have not been mastered. Below are the cultivation methods and precautions for Oncidium orchids.
I. Cultivation Methods for Oncidium Orchids
1. Soil Requirements
The soil should be fertile and well-draining. Enthusiasts can mix their own growing medium, for example, using fine fern soil, peat soil, charcoal, vermiculite, and broken brick stones, in a ratio of 4:1:2:2:1.
Before planting, place a layer of broken tiles at the bottom of the pot to improve drainage and increase soil aeration.
2. Light Requirements
Adequate light supply is beneficial for the growth of Oncidium orchids, but they prefer diffused light and dislike direct sunlight.
During the growing season, it is best to place them in a diffused light environment. In the summer, about 70% of the light should be blocked. In spring and autumn, about 45% of the light should be blocked. In winter, keep the Oncidium orchid potted plant in a sunny indoor location to ensure it receives ample diffused light.
3. Temperature Requirements
Different varieties of Oncidium orchids have different temperature requirements. A temperature range of 18 to 25 degrees Celsius is most favorable for thick-leaved varieties, with the minimum temperature not lower than 12 degrees Celsius. A temperature range of 10 to 22 degrees Celsius is most favorable for thin-leaved varieties, with the minimum temperature above 8 degrees Celsius.
4. Water Requirements
Oncidium orchids enjoy humidity, and during their growing season, the air humidity should be maintained at around 70%. When watering, the potting mix should be kept semi-dry. During the peak growing season, water twice a day, once in the morning and once in the evening, mainly with some thin water. In winter, with cold weather and low temperatures, water should be controlled appropriately.
5. Fertilizing Requirements
When potting, sufficient bottom fertilizer should be added, usually well-rotted bone meal and coconut shell. During the seedling stage, apply a special flower fertilizer once a month, along with some calcium fertilizer.
II. Precautions
1. Regular Potting Soil Replacement
For growing Oncidium orchid potted plants, the potting soil should be replaced every two to three years. When repotting, remove the old potting soil and replace it with freshly prepared nutrient-rich soil. Remove any rotting roots and withered branches. The soil should be disinfected before replanting.
2. Ensure Good Ventilation
Proper air circulation is beneficial for the healthy growth of Oncidium orchids. During the growing season, ensure good ventilation and shading, especially in spring and summer. When growing Oncidium orchid potted plants indoors, make sure to open windows for ventilation frequently. Even in winter, when it's cold, proper ventilation should be maintained to reduce the likelihood of diseases and pests.
