Can orchids be exposed to the sun?
The editor will explain the aspects of orchids, a member of the Orchidaceae family. Can orchids be exposed to the sun? The following is a detailed answer for you by the editor.
The question of whether orchids can be exposed to the sun cannot be generalized. Different seasons and different environments require different lighting treatment methods. As the saying goes, "orchids should not be exposed to the cold wind in spring, direct sunlight in summer, dry soil in autumn, and damp conditions in winter." This means that in spring, they should avoid cold wind attacks and not be moved outdoors; in summer, they fear direct sunlight and should be placed in cool and well-ventilated areas; in autumn, they should avoid dry potting soil, as this is the orchid's bud formation period and watering should be increased appropriately; in winter, they are in a dormant state, and excessive water can cause root rot, so the principle should be alternating dry and wet conditions.
Orchids prefer shaded, cool environments and dislike direct sunlight. Therefore, in the north, they can be exposed to more sunlight before 9 am in April and May, but after mid-May, they need to be shaded, and should be placed in cool, well-ventilated areas for cultivation, especially in summer when the shading should be greater to avoid harsh sunlight.
Among Chinese orchids, the one that can tolerate the most shade is the black orchid, followed by the autumn orchid, while the spring and summer orchids need more sunlight. Light is an important factor in the formation of orchid flower buds. Although orchids need appropriate shading during their growing periods in spring, summer, and autumn, keeping orchids in the shade all year round without allowing them to receive sunlight will also affect the differentiation of flower buds, leading to fewer or no flowers. Therefore, after the autumn coolness sets in, all kinds of orchids should be exposed to more sunlight or placed in areas with bright scattered light and good ventilation. In winter, they should be placed near the south window to receive more sunlight, which will enhance their vitality and promote flower bud differentiation. Especially for black orchids and cold orchids that bloom in winter, they should be placed in a sunny indoor area during the winter. Without sunlight, it is difficult for them to bloom well.
