Causes of yellowing of leaves and solutions

The chlorosis of yellow leaves of flowers is often caused by poor mastery of water, fertilizer, and light in the management process. Symptoms and methods of prevention and control are briefly described as follows: 1. The top leaves of yellow flowers are pale yellow and wilt, and the old leaves are dark. yellow. The wilting leaves were picked off by hand and the group was not bad, but it was still unfolding. The reason is that the water is long and wet, the soil is deprived of oxygen, and the roots begin to rot. Stop watering, loosen soil, allow water to evaporate, excavate part of the soil without damaging the roots, fill in dry nutritious soil, or bury moisture-absorbing substances in the basin, such as hygroscopic paper, chalk, and sponge. , cotton yarn, change once every 4 days. 2. The new leaves of the tops of the dry yellow flowers are normal in the night, while the old leaves of the lower leaves gradually dry upwards and the curls fall off. The reason is that the water is not irrigated for a long time, no loose soil, soil compaction, a lot of water volatilizes, causing water shortage in the plants, causing the lower branches and leaves to age. The measure is to put a half shade, put a little water, and loose the loose wall to drain water from the gap. 3. Fatty yellow and old leaves are hypertrophic and glossy, dark green in night, but the back of leaves is shriveled, leaves spread, old leaves gradually fall off, the new leaves are severely closed, the whole leaves are yellow, and the branches are prominent. . The reason is that the amount of fertilizer is too large and too thick, the water control should be stopped, and the pots should be placed in the shade to reduce the soil moisture and regulate the exertion of the fertilizer effect. If it is caused by chemical fertilizers, it should be replaced in a timely manner, first remove all the leaves, replanting, watering should be appropriate, a small amount of ground pouring, put a half overcast management, after the germination of new leaves, then transferred to normal support . 4. Weak yellow branches, thin yellow leaves, no growth and germination power, growth "will die." The reason is that the plants are large and the pots are small. For many years, the flower pots have not been replaced, nutrient soils have been replaced, and the roots have to be densely packed and aged. Fertilizer should be added in time to increase nutrients, conditional pouring of liquid decomposes fertilizer and water to promote its ability to restore growth. 5. Illumination causes yellowing of flowering leaves mainly due to improper management. The flowers are like sunshine, hi sunshine and shade tolerance. When the light is strong, the branches and leaves are yellow, wilting, and tip coke, such as bamboo. However, the opposite is true for bougainvillea and oleander. Weak light branches have long legs, small flowers, small leaves and yellow off, such as Chinese rose, but adapt to Monstera and Tiger blue. As long as the full understanding of the habits of flowers, reasonable placement of flowers, timely adjustment of light, shade the time, will branch will be green and colorful. Yellow flowers and leaves, but also by the soil pH, pests and diseases, phytotoxicity, smoke and dust, changes in the level of humidity, the imbalance in the proportion of trace elements in the soil, poor ventilation and other factors will also cause the leaves to yellow. As for the metabolism of branches and leaves, the temporary imbalance of nutrient water after transplanting, and the withering of leaves during dormancy, it is a normal physiological phenomenon of the plant.
