Charcoal ash as fertilizer

Charcoal ash can be used as fertilizer, but it depends on the situation. Because this substance becomes strongly alkaline when it comes into contact with water, it is more suitable for growing alkaline-loving plants. If the plants prefer acid, they will easily be burned to death.

Charcoal ash can be used as fertilizer for alkaline-loving plants, such as hibiscus, pomegranate, oleander, costus root, wolfberry, sunflower, forsythia, elmleaf plum, torch tree, cactus, etc.

How to make charcoal ash fertilizer

1. Soil configuration: Charcoal ash is generally used as an auxiliary material in growing succulents. It is best to configure it with nutrient soil in a ratio of 1:5, which is enough to supplement nutrients for the plants.

2. As fertilizer: Charcoal ash can also be used as foliar fertilizer. Add clean water and mix evenly. It can be sprayed on the leaves of the plant to supplement its nutrients.
