Potting soil assassins every orchid
If orchid soil is mentioned, it is not commercially available potting soil. Orchids thrive on epiphytes from giants of the jungle. With their numerous aerial roots, they cling to the branches and extract vital moisture from the rain. Consequently, the tropical plants cannot survive in soil.
The main components of orchid soil are pieces of bark to simulate the natural conditions. Inorganic additives such as lava granulate (€ 13.76 at Amazon *) expanded clay (€ 17.50 at Amazon *) or zeolite ensure airy permeability. Organic additives such as sphagnum, coconut fibers, peat or nutshells give off valuable nutrients. If you pot orchids in potting soil, rot and disease are inevitable.
