Sawdust as fertilizer

Sawdust can be used as fertilizer. Sawdust generally refers to the waste left after wood processing. It is a good material for making organic fertilizer. It is rich in nitrogen, phosphorus, potassium and other trace elements. It can also increase the air permeability of the soil and is very suitable for plant growth.

Sawdust can be used as flower fertilizer and can be used to grow orchids, phalaenopsis, white calla lilies, azaleas, kumquats, camellias, osmanthus, gardenias and other plants, and it is beneficial to their growth.

How to make sawdust fertilizer

First, put clean sawdust, cake fertilizer, chicken manure fertilizer and other materials into a bag and add appropriate amount of water. Then seal the bag and put it in a warm place for about 1-2 months. When the liquid inside turns dark brown, it can be used as fertilizer.

Key points for using sawdust fertilizer

1. Although sawdust can be used to grow flowers, the wood chips used for decoration contain certain formaldehyde, paint and other substances and cannot be used as fertilizer.

2. Make sure the sawdust is clean before using it, because the plants are very fragile. Unclean sawdust can easily cause insects to grow in the plants, causing the plants to become sick.
