This is the real cause of the yellowing of flower leaves and the solution. Don't get me wrong.

Yellowing of leaves is sometimes unavoidable in the maintenance of flowers. Many people do not know what causes the yellowing of leaves. Some use vinegar and some use beer, but can this really make the yellowing leaves turn green? At present, each has its own reasons for yellowing of leaves, but according to years of practical experience in flower cultivation, the causes and solutions of yellowing of flower leaves are sorted out as follows:

1. There is a lack of compound elements and trace elements in the soil, which often occurs when flowers are transplanted or changing pots without using base fertilizer, resulting in lack of nutrition. The lack of these nutrients and trace elements in the soil causes the leaves to turn yellow. Therefore, when flowers are transplanting or changing pots and changing soil, no matter what kind of soil is used, organic fertilizer should be used as base fertilizer. 2. Yellow leaves of flowers caused by soil acidification, acidification is the formation of acidic soil after a long period of weathering and the decrease of pH value, which affects the biological activity of the soil, reduces the availability of nutrients, and promotes the dissolving of free manganese and aluminum ions into the soil solution. inhibit the development of roots, produce toxic effects on flowers, resulting in malnourished leaves and yellow leaves, therefore, the soil with high humus content should be selected for flower cultivation. A large amount of organic matter can balance the structure of the soil. in addition, potted flowers should be changed after one or two years.

3. When the humidity is too high, many people are always afraid that the potted soil will dry, so that the potted soil will not be dry every day, and it will be in a wet state for a long time, affecting root respiration and nutrient absorption, resulting in yellowing leaves. The correct watering method is to see that the surface of the soil layer is dry before watering. 4. Only know how to use chemical fertilizer, but ignore organic fertilizer, which leads to the change of soil structure, the decrease of looseness, poor air permeability, and the ability of absorbing water and nutrients. Therefore, flower fertilizer is only used as an auxiliary fertilizer for flower cultivation, and the main fertilizer should be organic fertilizer.

5, the leaves yellowed due to improper fertilization, many flower growers often use too much fertilizer to flowers, or apply it to the roots, resulting in excess nutrients, poor root absorption and yellow leaves. Therefore, fertilization must be moderate and stop, not too much, not too close to the root system. 6, the harm of diseases and insect pests, when the occurrence of diseases and insect pests, will cause the destruction of chlorophyll in leaf tissue, followed by leaf spot disease, yellow leaves, yellowing and shedding and other phenomena, once found should be timely prevention and control.
