How to choose a potting medium for orchids? Master these key points
The choice of potting medium is very important for growing orchids. Since most orchids like moisture but fear wetness and require ventilation and air circulation, the medium should be made of materials that can absorb water and allow air circulation.
Secondly, orchids also need nutrients, so the medium should be mixed with organic matter and other substances that can gradually release nutrients.
Commonly used orchid potting media include
Sphagnum moss
Fern root

Coconut husk
Tree bark

Leaf mold

Palm fiber

Humus
Crushed bone
Feathers
Charcoal
Peat soil
Pond mud balls
Pumice
Sand and gravel
Vermiculite
Perlite
Clay pellets
Orchid growers can choose materials that are abundant locally, easy to obtain and low in price according to actual local conditions and cultivation requirements, and combine them reasonably.
