Orchidsprefer shade, but that does not mean they do not need sunlight;orchidslike to grow in diffused light. If too much attention is paid toorchidsbeing shade-loving and they rarely see sunlight, the nutrients produced by photosynthesis will be insufficient, causing the stems and leaves to become thin and weak, and the plants often fail to produce flower buds.
Although orchids prefer shade, they still need a certain amount of light, and especially need the nourishment of rain and dew. Only in this way can they grow robustly and bloom abundantly. Therefore, orchids kept indoors for a long time should preferably be moved at regular intervals to a balcony or courtyard to receive sunlight and rain and dew.
Because orchid species differ, their requirements for sunlight also differ. Generally speaking,Cymbidium goeringiiprefers partial shade,Cymbidium faberi, autumn orchids and others can tolerate slightly more sun, but this should also be adapted to local conditions according to the environment around theorchid-growingsite. During the hot midsummer period, switch to dense shading; when the morning sun first rises, immediately lower the curtain, and only remove it when the orchid shed no longer receives sunlight before evening.
After "White Dew," the weather gradually turns cool in autumn, the new growths have all matured, and the flower buds have broken through the soil and become established. At this time shading is unnecessary; on the contrary, the plants should receive more sunlight to promote photosynthesis and accumulate more nutrients, which benefits growth in the coming year and also makes the flower buds plump and upright.
During the winter maintenance period indoors, the glass in the windows should always be kept clean and bright so that light can pass through fully. If the sun is shining and it is not freezing outdoors, at noon the window can be left slightly open to let in the warm sun, which both ventilates and lets in light and also raises the room temperature. On calm, clear days in early spring, before noon, the potted orchids can be placed in the sunlight in batches to bask a little longer. From early summer to early autumn, direct exposure to sunlight must be strictly avoided. (Lin Qingde, Mu Wei)
