Camellia is a kind of flower that we often see in our daily life. It is deeply loved by flower growers because of its rich fragrance and gorgeous flowers. So what is the reason for the yellowing of camellia leaves? How to remedy the yellowing of camellia leaves? The following editor will explain them one by one, hoping to help you. Why do camellia leaves turn yellow?1. Normal situation after repottingIf we have just changed the pot for the camellia, it will need a certain amount of time to recover. During this process, some leaves will definitely turn yellow because its roots have not yet fully grown, so the absorption of nutrients and water will be lacking. It will be fine after a few days when it adapts to the pot. 2. Too much wateringCamellia must not be watered excessively. Its root system is relatively thin, so it absorbs water slowly. If we always water it too much, water will easily accumulate in the pot, and the aerial roots will be blocked, making it very difficult for the roots to breathe. Over time, the water in the leaves will gradually become depleted, and the leaves will easily turn yellow. 3. The occurrence of pests and diseasesIf camellia has pests and diseases, it will also cause the leaves to turn yellow, such as the red spider mites and leaf blight we mentioned. We need to take the corresponding pesticides for spraying to effectively solve the development of pests and diseases. It can gradually restore the green color of the leaves. 4. Lack of fertilizerIf the leaves of our camellia turn yellow at the beginning, we can add some nitrogen fertilizer to help the growth of the leaves and effectively restore the color of the leaves. However, in the later stage, when the camellia blooms, we need to apply some phosphorus fertilizer or potassium fertilizer, because these two fertilizers can promote the growth and opening of camellia flowers. How to remedy the yellowing of camellia leaves1. Physiological natural aging. Generally, new leaves will grow after the yellow leaves are removed. It can be supplemented by spraying growth regulators. 2. Lack of trace elements can be supplemented by spraying foliar fertilizer appropriately. 3. There are mites on the back of the leaves, which have absorbed the juice from the leaves. You can spray with bifenazate, etoxazole, spiroclotamil, etc. 4. The roots may rot and fail to absorb nutrients and transfer them to the leaves, causing the leaves to lose their green color. This situation is basically irreparable. The only thing to do is to pull out the diseased plants, and use meconium, carbendazim, and siloxane to irrigate the roots of the remaining uninfected plants for prevention. How to care for camellia in daily lifeCamellia has high requirements for soil. When planting, you can buy special soil for camellia in the market and mix it yourself. Make sure the soil is nutritious enough. Camellia also has requirements for the temperature and humidity of the environment. It likes to grow in a humid environment. When the weather is hot, the soil should be kept moist. When the weather turns cold, the soil should be drier. Camellia needs some fertilizer when it reaches the flowering season. You can dilute the phosphorus fertilizer and nitrogen fertilizer with water and then pour it into the soil in the flowerpot. |
