What Happens When the Leaves of Oncidium Turn Yellow
The editor introduces why the leaves of Oncidium turn yellow and knowledge about the cultivation techniques of Oncidium and flowers. Next, the site editor will introduce to netizens.
Light Conditions: It prefers a semi-shaded environment, avoiding direct sunlight in summer and requiring sufficient light in winter.
Soil Environment: Use a breathable substrate for cultivation and repot every spring to ensure stronger soil aeration and drainage.
Appropriate Moisture: Keep the soil slightly moist, spray water on the plant appropriately, and maintain humidity above 60%.
Precautions: In summer, provide shading and avoid rain, and in winter, the northern regions need to bring the plant indoors early for care.
I. Light Conditions
There are many varieties of Oncidium, and most prefer to grow in a semi-shaded environment, unable to tolerate long periods of direct sunlight, especially during the intense sunlight of summer. Brief exposure to direct sunlight can damage the tissues in its leaves, leading to wilting and yellowing, which is not conducive to the overall growth of the plant. If it is being cared for indoors in winter, placing it in a well-lit position can be very beneficial for its growth in the following year.
II. Soil Environment
Oncidium prefers to grow in soil with good breathability. Generally, cultivation involves using substrates such as bark, coconut bran, and sphagnum moss, which have good drainage and aeration, conducive to root growth, while also maintaining sufficient humidity in the substrate. Additionally, it is necessary to change the potting soil every spring to ensure normal growth.
III. Appropriate Moisture
Oncidium has a high demand for humidity. In addition to regularly watering to keep the substrate slightly moist, it is also necessary to spray water on the plant or around it to maintain moisture, keeping the air humidity above 60% to promote growth. If caring for the plant in northern regions, it is recommended to place a bowl of water nearby or install a humidifier to avoid excessively dry air affecting its growth.
IV. Precautions
Summer and winter weather are not conducive to its growth. In summer, it is important to provide shading and prevent rain. If it's a light rain, it can be placed outdoors to get a little rain. In winter, the cold climate in the north is not suitable for its growth, so it needs to be moved indoors early and maintain the indoor temperature above 15°C to ensure it can survive the winter safely.
