Precautions for cultivating oncidium

Soil Requirements

Oncidium prefers a drier environment. Before planting, lay a layer of broken tiles and broken bricks at the bottom of the pot. It is best to choose soil with good drainage and air permeability. , you can choose to mix 4 parts of crushed fern roots, 1 part of peat soil, 2 parts of crushed charcoal, 2 parts of vermiculite, and 1 part of sphagnum moss.

Light and temperature requirements

Oncidium prefers a semi-shady environment. In winter, it can be maintained under full sun without shading, which can promote plant flowering. In other seasons, shade should be provided to prevent the leaves from being burned.

Different varieties of oncidium have different temperature requirements. The temperature for thick-leaf varieties cannot be lower than 12°C, and the optimum growth temperature is 18~25°C; the optimum growth temperature for thin-leaf varieties is 10°C. ~22℃, the minimum temperature cannot be lower than 8℃.

Water and fertilizer requirements

Oncidium prefers a drier environment and can be watered when the soil surface is dry. During the growing season, the amount of watering can be increased appropriately, once in the morning and once in the evening to ensure that there is no accumulation of water. Reduce the amount and frequency of watering in winter and control water to facilitate flowering. Stop watering when the temperature drops below 10°C to avoid frostbite.

In spring and autumn, apply organic fertilizer every 20 days, with a balance of various elements, either by root irrigation or leaf spraying. Do not fertilize when the temperature is too low in winter.

Watering method

In summer, you need to pay attention to shading, and when the temperature is high, you need to cool down in time. In midsummer, water once a day, water thoroughly, that is, water until there is water flowing out from the bottom of the flower pot. At normal times, water when the soil is half dry.
