Grass ash, as the name suggests, is the embers of a plant after it has been burned. In this seemingly ordinary ash, there are rich mineral elements, such as potassium, calcium, magnesium, phosphorus, etc. These mineral elements play a vital role in the growth of green vegetables. Theoretically, these minerals in plant ash can indeed be used as fertilizer to help greens thrive.
However, in practice, we also need to pay attention to some properties of plant ash. The temperature of the plant ash is high, and if it is sprinkled directly on the newly grown greens, it may burn the seedlings and hinder their normal growth. In addition, the alkalinity of plant ash is strong, and excessive use may lead to an imbalance in soil pH, which will affect the growth of green vegetables.
Therefore, in order to ensure the healthy growth of greens, we recommend that proper treatment should be carried out when sprinkling grass ashes. First of all, the plant ash should be mixed well with the right amount of soil, which will reduce its temperature and neutralize its alkalinity. Then, sprinkle the mixed fertilizer near the roots of the greens, avoiding sprinkling directly on the leaves to prevent unnecessary damage.
It is important to note that plant ash is not a substitute for organic and chemical fertilizers. It can only be used as a supplementary fertilizer to replenish the mineral elements in the soil. When using, it should be used in moderation according to the fertility of the soil and the growth of green vegetables to avoid unnecessary losses.
In summary, although plant ash contains mineral elements that are beneficial to the growth of green vegetables, freshly grown green vegetables still need to be handled with caution when sprinkling plant ash. Only when plant ash is used correctly can its potential to promote the growth, quality and yield of green vegetables be realized.
