Dendrobium candidum is generally more common in the south, distributed in the provinces south of the Huaihe River, such as Guangdong, Hunan, Guangxi, Zhejiang, Anhui, Yunnan and so on.In fact, Dendrobium candidum can be raised in the north, but can not be planted in the open air, need to build greenhouse to plant, so as to better control the light, humidity, temperature and other factors, easy to maintain and manage, but also to avoid the situation of non-survival.In fact, some areas in the south also need to build greenhouses to maintain, and areas with higher temperatures can be planted directly in the forest.However, in the north, the cost of planting and maintenance is more, and the medicinal properties may be worse.
When planting in the north, it is necessary to choose a good place to build a greenhouse. When choosing a place for planting and maintenance, it is necessary to keep away from pollution sources, have a convenient and clean water source around, have a higher humidity in the surrounding environment, and have good ventilation and reasonable maintenance.
Dendrobium officinale has a strong ability to resist drought, but it likes a humid growth environment. If there is water shortage and drought for a long time, the leaves will turn yellow, so it needs to be watered in time, but it can not be watered too much to prevent water accumulation and root rot, which will affect growth.
