What if the bonsai leaves at home are a little yellow?

The yellowing of bonsai leaves is caused by many factors: excessive watering, lack of fertilizer, lack of light and so on.

1, caused by excessive watering, the roots have rotted, carefully loosen the soil to let the roots breathe, and the plant growth should conform to the natural state;

2. Insufficient fertilization will lead to the lack of basic elements of synthetic nutrition needed by plants, mainly nitrogen, phosphorus and potassium, which will make plants yellow. Dozens of compound fertilizers should be evenly applied to the surrounding soil once every two months, and some slightly acidic fertilizer water, such as fermented light rice water, should be watered frequently, not watered;

3. The place where bonsai is cultivated is dark, so it should be moved to a place with sufficient light for cultivation. Because insufficient light will cause the lack of nutrition and the obstacle of evaporation cycle in plant photosynthesis production, which will lead to the yellowing of leaves.

4. Due to excessive fertilization or high concentration, especially the yellow leaves caused by partial application of nitrogen fertilizer, fertilization should be stopped, water should be appropriately increased, and nutrients should be diluted. At this time, it is necessary to change pots and soil, usually from rainy to long summer.

5. I like sour potted flowers, such as camellia, Milan, Michelia, Rhododendron and Jasmine. Due to the alkaline reaction of soil, they often lose their green and yellow colors. For this "yellowing" phenomenon, acid fertilizers or acidic substances can be used to improve it, and alum fertilizers can also be used frequently.
