Fish bones as fertilizer

Fish bones can be used as fertilizer. They are rich in nutritional value and can promote the growth needs of plants. However, they must be fermented before use, and the salt in the fish bones must be washed away before use.

Fish bones are used as flower fertilizer and are more suitable for use with taller flowers, such as azaleas, roses, jasmine, etc. They can supplement phosphorus for the growth of flowers.

How to make fertilizer from fish bones

1. Pour the fish bones back into the container and soak them in clean water overnight. Wash away the salt after repeated washing, then steam them in a pressure cooker for about 20 minutes. Remove the fat, take out and dry them, then mash them to become bone meal, which is a nutritionally complete base fertilizer.

2. In addition, you can also put the fish bones into the tank, add an appropriate amount of Jinbaobei fermentation agent and a small amount of water, maintain the humidity at about 60%, and the fermentation will be completed after a period of time.

Key points for using fish bone fertilizer

Fish bones cannot be placed directly in flower pots as fertilizer. Not only will they ferment and dissipate heat in the pot, they will also attract pests such as ants and white nematodes, causing the leaves of the plant to turn yellow. At this time, it is necessary to replace the potting soil and replant.
