Buying orchid potting medium: know these points and orchid roots will grow well, blooming every year

Most orchid growers know that planting orchids requires loose, breathable, well-draining granular material rich in humus. What we can commonly use includes: pine bark scales and pine bark chunks, coconut husk, tree fern fiber, coarse-fibered leaf mold, peat soil granules, willow bark, jujube bark, peanut shells, and so on. These are all potting media that contain a certain amount of nutrients.

In addition, there are some materials that only serve to drain water and provide air permeability. They themselves have little nutrition; when added to other potting media, they only serve the function of absorbing and releasing water. These materials include volcanic stone, ceramsite, processed red brick granules, Kanuma soil, and large-grain perlite, among others. They are all fairly good additive materials.

Because these mineral additive materials have no nutrients, they generally cannot be used alone; they can only be added in appropriate amounts or used as a top dressing on orchid pots. These orchid-growing materials are generally sold in flower markets, and most potting media can also be bought online. Orchid growers can choose and buy according to their own usage amounts.
