What soil does the orchid change?

Orchid is a succulent root plant, which requires loose and fertile soil, good drainage and acidity, and often uses multi-system mountain mud However, when planting in the upper basin, there should be more and thicker gaskets at the hole at the bottom of the basin. The gasket should be covered with a layer of broken mud particles. Only after the broken mud particles are wrapped in fine mud can you put the orchids into the pot and then add the mountain mud. This planting method is mainly based on orchid's habit of loving humidity and avoiding water accumulation, so that the drainage is smooth. When using mountain mud, if 1/3 coarse river sand is added, it will be more conducive to drainage and more in line with the growth habits of orchids. The soil for cultivating orchids in the north is neutral and acidic, containing a lot of humus, which is loose and well drained. Many garden units in the north collect and transport mountain mud from Shaoxing, Zhejiang and other places to cultivate rare varieties. Although it is beneficial to the growth of orchids, the water quality in the north is hard, so it will be replaced in two or three years, and the long-distance transportation price is higher. In recent years, 30% local peat soil, 1% river sand, and some organic fertilizers (which need to be stacked for a period of time) are used as soil for potted orchids, and the growth is also good. Saprophytic soil under broad-leaved forest in northern mountainous areas, saprophytic soil composed of deciduous broad-leaved trees and culture soil containing 60% humus can all be used to cultivate orchids. The epiphytic orchids in potted plants in northern China include Dendrobium, pig excrement beans and dictyophora indusiata. Potted plants can't use soil. Common cultivation materials are sphagnum moss, fern root (water dragon root or purple dustpan root) and a small amount of rotten leaves of broad-leaved trees, small pieces of charcoal and dried cow dung. In addition, broken bricks can also be used to pad the bottom of the pot.
