Can orchids be grown with sawdust?

Sawdust can be used to grow orchids. Sawdust falls from the wood, so the texture is relatively soft. This can provide a loose and breathable environment for flowers when they are planted, thus promoting root growth and absorption.

Advantages and disadvantages of growing orchids in sawdust

Advantages: Sawdust has good air permeability and certain drainage properties, and can generally release some fertility. It is also relatively easy to obtain, easy to disinfect, contains very few pathogens, and has a light texture that will not increase the burden on the roots.

Disadvantages: The texture of sawdust is relatively dry, so it is difficult for it to absorb moisture. Also, if it is not treated with high temperature, it is easy to breed some bacteria.

How to grow orchids with sawdust

1. Composting: Sawdust needs to be composted before it can be used. You can spray the sawdust with water or soak it in urea water. Then put the wet sawdust into a sealed plastic bag and place it in a sunny place to ferment. When the sawdust turns black, it can be used.

2. Prepare the soil: The decomposed sawdust needs to be ventilated and dried for 1 or 2 hours before use. After that, it can be planted together with peat soil and leaf mold. This way, the soil for the orchid can maintain sufficient fertility.
