What if the leaves of the latest camellias turn yellow?

Camellia is one of the top ten famous flowers in our country, and now it is the cultivation object of many horticultural plants. The figure of camellia can also be seen in every flower shop. Its petals are very many. There are dozens of petals on a flower, attracting the cultivation and cultivation of many flower lovers. What should we do if we encounter the phenomenon of yellowing leaves in the breeding process? Next, Shuai Shuai will talk about the reasons and solutions for the yellowing of camellia leaves.

1. Normal yellowing

Camellia is an evergreen plant, the general leaves can be kept for about 3 years, but as long as green plants are sure to fall leaves, between April and May, some of the old leaves in camellias slowly yellowed and then fell, this is the role of normal metabolism of plants, will not affect plants, so if this is the case, you don't have to worry.

2. Lack of growth elements

When cultivating camellias, the leaves may turn yellow due to lack of trace elements. For example, plants will yellowed if they lack nitrogen. Once this happens, fertilizers should be added. Once every other month, mature bean cake water is applied to the soil, or 1% ferrous sulfate solution can be put in, so that the trace elements that camellias lack can be replenished.

3. Soil problems

Sometimes there may be problems in the soil that lead to the yellowing of camellia leaves. Problems with soil acidity and soil nutrients will affect the growth of camellias. Camellias like the acidic soil environment like other plants, so it is likely to make the soil environment of the area where the breeders are not good, because if some northern friends plant, the northern soil is slightly alkaline, which will make the leaves yellow. In addition, not changing the soil for a long time leads to the loss of soil fertility, so it is best to change the soil regularly, and it is better for the soil to choose soil rich in humus, which can be sprayed with foliar fertilizer for camellias, which can alleviate the yellowing of leaves and inhibit the degree and speed of yellowing.

4. Watering problem

The long-term exposure of the soil to too dry soil or too moist soil leads to difficulty in root breathing and yellowing of leaves, and root decay will affect the nutrient absorption of leaves. We should water the plants properly regularly and observe whether there is a lack of water before watering. If the soil is white, it means it is lack of water.

5. the problem of diseases and insect pests

Camellia will inevitably encounter the harm of diseases and insect pests in the process of culture, such as red spiders and shell insects, which will absorb the juice and nutrients of the leaves, so that the leaves yellowing, serious will lead to leaf shedding. We can buy the corresponding pesticides in the market, if it is harmed by red spiders, we can use 50% of the solution of phosphorus trichloride to kill, and if the scale insects are harmful, we can use special agents to spray and kill them, and take good control measures.

The above are the reasons and solutions for the yellowing of camellias leaves. The most likely cause of camellia leaves yellowing is caused by lack of nutrition and the harm of diseases and insect pests. Usually we should observe more changes on the leaves. If the leaves appear wormholes or are eaten traces are likely to be infected with insect pests, so we should learn how to judge the causes of leaf yellowing and finally prescribe the right medicine.
