Can sawdust be used to grow orchids?

Sawdust can be used to grow orchids. Sawdust cannot be used when it is just cut. It usually needs to be fermented until it turns black before it can be used. Generally, orchids grown with sawdust can obtain more nutrients in the soil, and the orchids will grow vigorously.

The pros and cons of growing orchids with sawdust

Advantages: Sawdust contains a lot of elements such as nitrogen, phosphorus and potassium, which can provide sufficient nutrients for the growth of orchids. In addition, sawdust has good air permeability and a relatively loose texture, which can achieve the effect of moisturizing and diuresis.

Disadvantages: Sawdust is a wood material. When it is moist, it is easier to breed fungi and bacteria. When the sawdust is very dry, its water absorption capacity will be poor, which will cause the orchid to lack water.

How to grow orchids with sawdust

1. Fermentation: Sawdust needs to be fermented in advance before use. It is usually placed in a sealed container, soaked in clean water, and then fermented in a high temperature environment for 3 months.

2. Mix the soil: Sawdust cannot be used alone and has certain limitations, so it can be planted with some weathered rocks, brick particles or coal slag. After planting, it can also be left on the surface of the soil to maintain fertility.
