How to do the yellow and dry leaves of camellia leaves, the cause of yellow leaves/cut dead leaves spray

First, what if the leaves of camellias turn yellow and dry, and cut off the dead leaves

Camellia is easy to raise and is a common flower plant in daily life. Any plant can turn yellow, and camellia is no exception. Earlier, we talked about the breeding methods and precautions of camellias, and now we talk about a common problem: what to do when the leaves of camellias turn yellow and wither. A series of problems such as watering, light, soil and so on may be the cause of the yellow leaves of camellia, but no matter what the reason is, we have to lose these dead leaves, which we will explain one by one below.

Second, the reasons for the yellowing of camellia leaves.

1. Improper watering

The problem of watering is mainly that it is too dry or too wet for a long time, which will lead to water yellow and dry yellow. Watering too much, the basin soil will be too wet, resulting in stagnant water, easy to lead to camellia root rot, causing leaves yellow and withered and leaf loss. Less watering, a long period of drought or dry air will make it short of water and the leaves turn yellow.

Watering precautions: generally, it can be watered more appropriately in spring to facilitate sprouting and shoots. Summer adhere to early and late watering, it is best to spray foliar water, so that the leaves are drenched, do not use rapid water direct watering, full irrigation, should not water hot water, avoid high temperature around noon watering; autumn watering should be appropriate. In winter, it is appropriate to water around noon, but spray water every two or three days.

2. Soil

The yellowing of camellias leaves may be caused by soil, including soil pH and soil nutrients. Camellia is a plant that likes acidic soil, but in the north, the soil solution is alkalized, which makes its leaves yellow. There is a gradual lack of nutrients in the soil, so that the lack of nutrients, leaves green.

Solution: what if the soil causes the leaves of camellias to turn yellow and dry? It is best to change the potted soil for camellias regularly, and the soil is rich in humus. Foliar fertilizer can be sprayed on camellias, which can slow down the symptoms of yellowing leaves.

3. Normal yellowing

Although camellias are evergreen plants, the leaves of camellias will not fall off during 2-3 years of cultivation, but they will still be changed. During the period from April to May, some of the old leaves of camellias will turn yellow and fall off. This is a normal metabolic phenomenon.

4. 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.

5. 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.

Solution: what if diseases and insect pests lead to yellow and withered leaves of camellias? 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 is the whole reason for the yellowing of camellia leaves. I hope it can help you all.

What to do about the yellowing of Camellia leaves? causes of yellowing of camellia leaves and their solutions

Camellia is one of our favorite flowers. What if the leaves of camellias turn yellow? Next, let's talk about the reasons and solutions for the yellowing of camellia leaves.

The reason for the yellowing of camellia leaves:

1. The yellowing or albinism of leaves in summer is due to the lack of phosphorus, iron, sulfur and other nutrient elements in the soil. The potted soil can be replaced and cultivated with humus-rich mud.

2. If the supply of nitrogen is insufficient, the leaves will turn yellow.

3. If the water is not properly watered, persistent drought or excessive wet will also cause yellow leaves.

4. when red spiders or shell insects harm plants, it will also lead to withered and yellow leaves.

The solution to the yellowing of camellia leaves:

1. Metabolism

Camellia is an evergreen tree, and its leaves do not fall off for 3 years after the formation of new shoots, but during the leaf change period from April to May, a small number of old leaves will also turn yellow and fall off, which is a normal phenomenon of camellia metabolism.

2. Soil discomfort

The yellowing or albinism of leaves occurs in summer because of nutrient elements such as phosphorus deficiency, iron deficiency, sulfur deficiency and so on. The potted soil can be replaced and cultivated with humus-rich mud. From April to September, the disease can be alleviated by using 300 times diluted ferrous sulfate leaching solution or spraying foliar with phosphorus trisulfide solution every 15 days. Spraying should be carried out in cloudy days and sunny days in the early morning or evening.

3. Lack of elements

In the process of camellia growth, if the supply of nitrogen is insufficient, the leaves will turn yellow. Can be applied with cooked bean cake water, once a month, the proportion of fat and water is 20% to 30%. If 1% ferrous sulfate solution is added to the fertilizer solution, the effect is better.

4. Improper watering

Camellia maintenance needs to pay attention to watering, if improper watering, persistent drought or too wet, will also cause yellow leaves. If the potted soil is too wet, the root system of the plant will turn black and rot, causing the leaves to yellowing and falling off. In a hot and sunny day, although the plant is shaded by a curtain, the basin soil often dries up and causes the leaves to yellowing and falling off.

5. Pest damage

Camellia will occur a variety of insect pests and diseases, when red spiders or shell insects harm the plant, it will also lead to withered and yellow leaves. Red spiders can be sprayed with 25% of the solution with 1000Mel 1500 times of water, or 50% of phosphorus trisulfide with 2500-3000 times of water, and shell insects can be sprayed with 5% of the solution.

Five reasons for the yellowing of camellia leaves and other control measures are introduced in detail.

Camellia is a common ornamental flower with many colors and charming fragrance, which is deeply loved by many flower friends. If its leaves turn yellow, it is bound to affect its ornamental value.
