Phalaenopsis orchids can be grown in peat soil, coconut coir, or special orchid soil. Peat soil contains substances decomposed from peat moss, sphagnum moss and the like, and has strong water retention and air permeability; coconut coir is the remaining fertilizer left after coconut shells are processed, and contains fibers and other substances; in addition, beginners can directly buy special orchid soil for cultivation to improve the survival rate.

1. Peat moss

Phalaenopsis is a flowering plant with aerial roots, and it needs soil with good water retention as well as good air permeability. Peat soil is formed from the decomposition or decay of substances such as peat moss and sphagnum moss. It has very good water retention and air permeability, and is often used in home cultivation. However, it is a non-renewable resource, so its substitutes are now commonly used.

2. Coconut coir

Coconut coir is the main substitute for peat soil. It is the fertilizer left after coconut shells are processed, and mainly contains the fibers of coconut shells, along with more nutrients, and it has good water retention and air permeability. Since it is the recycling and secondary use of fertilizer, it is beneficial to the environment.

3. Special orchid soil

Through continuous experimentation, merchants have their own secret formulas, and it generally has strong air permeability and water retention. This kind of soil is suitable for beginners who are just starting to grow orchids, and it can save time and improve the survival rate.
