Why do the leaves of camellia turn yellow?

There are many reasons for the yellowing of camellia leaves, including maintenance and management factors, as well as physiological factors.

The yellowing or albinism of leaves occurs in summer because the soil is deficient in phosphorus, iron, sulfur and other nutrient elements, which can be changed into potted soil and cultivated with humus-rich mountain 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.

If the supply of nitrogen is insufficient, there will also be yellowing of leaves. Rotten bean cake water can be applied once a month, and the ratio of fertilizer and water is 20% to 30%. If 1 ‰ ferrous sulfate solution is added to the fertilizer solution, the effect is better.

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.

When red spiders or shell insects harm plants, it will also lead to withered and yellow leaves. Red spiders can be sprayed with 25% dimethoate with 1000 times water, 1500 times with water, or 50% phosphorus trisulfide with water with 2500 times, 3000 times, and shell insects can be sprayed with 5% dimethoate solution.

Camellia is an evergreen tree, and its leaves do not fall off for 2-3 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.

If the supply of nitrogen is insufficient, there will also be yellowing of leaves. Rotten bean cake water can be applied once a month, with a ratio of 20% to 30%. If you add another 1%. Ferrous sulfate solution in fertilizer solution, the effect is better.

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.

When red spiders or shell insects harm plants, it will also lead to withered and yellow leaves. Red spiders can be sprayed and killed with 25% dimethoate plus water 1000 Mel 1500 times, or 50% trithiophos plus water 2500 Mel 3000 times; shell insects can be sprayed with 5% dimethoate aqueous solution.

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.

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.
