Orchid bark refers to a specific type of growing medium or substrate commonly used for growing orchids. It has unique growing requirements and the choice of a suitable growing medium is crucial to their health and well-being.

It is typically made from the bark of various tree species, such as fir, pine or redwood. The bark is usually shredded or cut into small pieces of varying sizes.


There are several reasons why it’s a popular choice for growing orchids:


Orchids need a well-draining growing medium to prevent their roots from being submerged in water because of the risk of root rot and the porous nature of orchid bark allows excess water to drain away freely.


Orchid roots need ample air flow to grow and the consistency of orchid bark allows air to circulate, preventing them from becoming over-saturated.

Moisture retention

Although orchid bark offers good drainage, it can still retain moisture. This characteristic allows the roots to have access to the necessary moisture, while avoiding water stagnation.


It provides stability to the orchid plant, helping it to anchor itself and prevent it from toppling over.


When using orchid bark as a growing medium, it is important to consider the specific requirements of the orchid species you are growing. Some orchids prefer finer bark, while others are better adapted to coarser pieces. It is often used in combination with other materials, such as sphagnum moss or perlite, to create a suitable mixture to meet the specific needs of the orchid species.

It is worth noting that although orchid bark is a popular choice for many orchids, different species and individual plants may have their own specific preferences. Therefore, it is always a good idea to research the specific needs of your orchids in order to provide them with the most suitable growing medium for optimal growth and health.
