Coal ash is often used as potting soil for succulent plants. Due to its strong drainage and air permeability, the roots of the plants will not be flooded. It also contains some trace elements that can supplement the nutrients needed for plant growth. In addition to planting succulents, it can also be mixed into potting soil to improve compaction. After it is mixed with animal manure and fully decomposed, it can be used as base fertilizer to provide certain nutrients.

1. Is it possible?

Coal ash is what remains after coal is fully burned. It has strong drainage and breathability, and also contains various trace elements, such as iron oxide, magnesium oxide, calcium oxide, etc. After high-temperature combustion, there will be basically no germs remaining. It can be used to grow succulents and can also be used as fertilizer after being decomposed.

2. How to use

1 , Make a selection: Not all coal ash can be used. Usually the cinders left behind by burning coal in factories are hard and contain a lot of heavy metals, making them unsuitable for use. Household briquettes are usually processed to reduce the sulfur and heavy metal content and can be used as substrate or fertilizer.

2. Water soaking treatment: Coal ash must be soaked first water treatment. Since it is an alkaline substance, it is detrimental to the growth of many plants. Soaking it in water can neutralize the pH. In addition, soaking in water can also remove excessively fine dust that may impair its breathability.

3. Fully decomposed: If you want to make coal ash into fertilizer, it needs to be decomposed. Put it together with animal manure or straw, and decompose it through high-temperature fermentation. This kind of organic fertilizer is generally used as a base fertilizer to promote plant growth.

4. Mixed into pot soil: In addition to being used as fertilizer, coal ash It can also be mixed into potting soil to increase drainage and air permeability of the substrate. But don't add too much, otherwise it will easily cause the loss of water and fertilizer, which is not conducive to its growth.
