1. Inhibition of pests and diseases
Grass and wood ash has a sterilizing effect. When I was playing with it when I accidentally injured my hands and legs, I was afraid that adults would blame me. So, I secretly learned to look like adults and wiped the grass and wood ash on the stove # Deep Good Writing Plan #. At the wound site, it not only stops bleeding but also does not cause inflammation.
When growing flowers, mixing a small amount of plant ash in the soil can reduce the invasion of pests and prevent diseases such as anthrax, powdery mildew, and root rot. And soaking plant ash in water and spraying it on the entire plant can prevent the occurrence of red spiders, aphids, and so on. For plants that are prone to lodging, plant ash can also be used to promote metabolism and prevent lodging.
2. Provide rich nutrition
Plant ash is rich in a large amount of elements such as potassium, calcium, iron, and magnesium, which are beneficial for plant growth. Especially potassium is one of the indispensable nutrients in plant growth. Potassium in plant ash can be quickly absorbed, promoting plant growth and enhancing plant resistance to diseases.
In addition, plant ash can also be used as foliar fertilizer. Before plants bloom, plant ash can be soaked in water overnight, filtered out residue, diluted, and sprayed onto the leaves. This not only makes the plant leaves more vibrant, but also promotes better photosynthesis, reduces flower drop, prolongs the viewing period, and enhances flower color.
3. Neutralize soil acidity
The soil acidity and alkalinity in the north and south are different, which has little impact on local plants. However, when plants grow in different regions, there may still be differences in soil acidity and alkalinity.
Some alkaline loving flowers are not adapted to acidic soil, are prone to damage, are not conducive to growth, and may even wither if left untreated. Grass and wood ash belongs to alkalinity and has the function of neutralizing soil acidity, which can increase the pH value of the soil and make it more alkaline. This is very beneficial for alkaline loving flowers, as it can protect their roots and allow them to thrive in a healthy environment.
However, for plants that prefer acidic soil, it is necessary to use less plant ash, otherwise it will affect the soil’s acidity and alkalinity, which is not conducive to plant growth. However, foliar spraying can be used to achieve the goal of supplementing fertilizer and preventing pests and diseases.
