What conditions are needed for orchid root growth

Whether orchid roots grow normally is the key to whether an orchid can grow well. Because orchids grow naturally in shady mountain areas, where the soil is loose leaf mold with good drainage, orchids have unique ecological habits; therefore, growing orchids must be based on this. Most orchid roots are fleshy, air-loving, and afraid of waterlogging. The common saying "air is the lifeline of orchid roots" refers to their need for air. Too much water easily causes root rot, and the replenishment of water should be decided according to the orchid species, growth conditions, weather, and the physical characteristics of the soil. "Not dry in summer, not wet in winter" is for Cymbidium ensifolium and Cymbidium sinense; "not dry in autumn, not wet in spring" is the water supply requirement for Cymbidium goeringii and Cymbidium faberi. As for Cymbidium goeringii, fine-rooted varieties such as Duoduo Eryun Shuihong and Chun Erhong have higher water requirements; while Chun Jian, Xuelan, and the Suxin types have lower water requirements.
