Plant ash is the product of plants after burning, it contains a lot of mineral elements such as potassium, magnesium, sulfur, and phosphorus. So what is the role of plant ash?

1. Enhance the alkalinity of the soil
Each plant has different requirements for the soil, and the soil is divided into acid, alkali, and neutral. Plants can grow better in suitable soil. Plant ash has the effect of enhancing the alkaline mineral elements of the soil, and it is suitable for mixing it into the plant pot soil that likes to grow in alkaline soil.

2. Increase potassium
In fact, the content of potassium in plant ash is relatively high, and it also contains mineral elements such as magnesium, sulfur, and phosphorus. However, mixing plant ash into the soil will dilute a large amount of nitrogen. When using plant ash mixed soil, if the plant has a high demand for nitrogen, then it is necessary to add nitrogen fertilizer to the soil in time.

3. Prevention of diseases and pests
When planting suitable plants with plant ash mixed soil, it can increase plant resistance and prevent insects from approaching. It has a very good function of preventing diseases and insects. It is very suitable for breeding plants that like to grow in alkaline soil.

4. Improve photosynthetic efficiency
Plant ash can not only be mixed into the soil, but also can be mixed into clean water. In autumn and winter, the ash water can be sprayed on the leaves of plants, which can help plants photosynthesize, prevent plant leaves from falling, and improve the ornamental value of plants. However, it cannot be sprayed on plants that like acid soil.

5. Sterilization and disinfection
Every time the plant is reproduced by cuttings, ramets, etc., or when the roots and branches are trimmed, wounds are left. At this time, the application of plant ash on the wound can have the effect of sterilization and disinfection, promote the rapid healing of the wound, and prevent diseases during plant reproduction, and increase the success rate of cutting and ramification reproduction.

6. Promote germination
There are many mineral elements contained in plant ash, which can make plants grow better in the soil. Usually when planting plants that like to grow in alkaline soil, plant ash can be used instead of soil to cover the seeds, so that the seeds have a better germination environment and promote the seeds to take root and germinate quickly in the soil.
