Bamboo charcoal ash as fertilizer

Bamboo charcoal ash can be used as fertilizer. If there are no plants planted in the soil, it can be mixed directly. However, if plants are planted, it must be mixed with water and properly fermented before it can be applied. Applying bamboo charcoal ash can make the soil more fertile.

Bamboo charcoal ash can be used as flower fertilizer, but if you already have flowers planted, you need to add a certain amount of water to the bamboo charcoal ash for fermentation before you can irrigate it into the soil to act as fertilizer for growing flowers. It is generally suitable for growing flowers such as roses and Clivia.

How to make fertilizer from bamboo charcoal ash

1. Remove impurities

When making fertilizer from bamboo charcoal ash, in order to keep the soil clean, you must first sift the ash with a fine mesh sieve to remove larger debris in preparation for subsequent fermentation.

2. Add water for fermentation

Then, add a certain amount of water to the sifted bamboo charcoal ash, put it into a sealed container, move it under the sun and let it stand for about a month, and you can get organic fertilizer.

Key points for using bamboo charcoal ash fertilizer

1. Stay away from plants

Bamboo charcoal ash fertilizer is highly alkaline. When applying it to the soil, be careful not to pour it directly onto the rhizomes, as this will cause an acid-base imbalance in the plant roots, leading to root burn and damage to the plants.

2. Add appropriate amount

Bamboo charcoal ash fertilizer will increase the soil concentration a lot in a short period of time. If applied in large quantities, it will easily cause the plants to absorb water in reverse through the soil, eventually causing the roots of the plants to lose water or even cause the plants to wither and die.
