First, flowers and leaves evergreen yellowing, looking for the cause

In life, because of the beauty of evergreen flowers and leaves, many people will plant it at home. But many of them did not look at the breeding methods of evergreen flowers and leaves, resulting in yellow leaves because of fertilization, temperature and soil. As for the yellow leaves of evergreen leaves, we just need to find the cause and solve the problem.

Second, the causes and solutions of yellowing of leaves of evergreen leaves.

1. Soil alkalinity.

Evergreen is most suitable for growing in loam soil which is loose and fertile, well drained and rich in organic matter, which is slightly acidic. But in the process of breeding, flower friends change the soil into alkaline soil, or pour alkaline water for a long time, which will cause flowers and leaves evergreen soil leaves to turn yellow. The reason for this is that due to the lack of elements such as soluble iron that can be absorbed, the leaves will slowly turn yellow.

The solution is very simple: change the basin soil and replace it with a new type of culture soil; if the yellow leaves are not serious, you can often pour alum fertilizer water to change the acid and alkali of the soil.

2. Improper fertilization

Excessive fertilization: evergreen flowers and leaves like fertilizer, the growth process needs appropriate fertilization to ensure adequate nutrients, but fertilization can not be too much, otherwise there will be new leaf hypertrophy, and uneven, the old leaf dry tip scorched yellow shedding solution: immediately stop fertilization, increase the amount of water, so that fertilizer loss, or immediately pour pot, rinse bulb with water and then replant into the pot.

Insufficient fertilization: the growth of evergreen flowers and leaves is inseparable from fertilizer, once there is no application of nitrogen fertilizer or did not change the basin for a long time, resulting in the lack of nitrogen and other nutrients in the basin soil, the branches and leaves will be thin and yellow. Solution: change into new culture soil in time, and gradually apply rarefied mature liquid fertilizer or compound flower fertilizer.

3. Improper temperature

The temperature is too low: the flowers and leaves are always green and like a warm environment. If the temperature is too low in winter and there are no measures to keep warm, the plants will appear yellow leaves and die in severe cases. Solution: adjust the temperature in winter to keep the room at 13: 18 ℃.

The temperature is too high: the flower and leaf evergreen is not heat-resistant, once the room temperature is too high, the plant transpiration is too high, the root water and nutrients are in short supply, and the leaves will turn yellow. Attention should be paid to timely adjustment of room temperature. Solution: control the temperature in summer so that the temperature does not exceed 30 ℃.

4. The light is too strong

Plants with evergreen flowers and leaves like semi-shade, so they need shade when the light is strong except in winter.

5. Plants are too dense

Some flower friends think that the denser the flowers and leaves grow, the better. In fact, this is wrong. Because when the flowers and leaves of evergreen grow too luxuriantly, coupled with long-term unpruned, the plant will be too dense, the leaves inside can not receive light, and the phenomenon of yellowing and shedding.

Solution: nitrogen fertilizer can not be less, but not more; in addition, strengthen pruning to make it ventilated and transparent.

The reason for the yellowing of evergreen leaves

Raising evergreen at home will encounter the situation of yellowing leaves, don't worry at this time, first make clear what the reason is, and then prescribe the right medicine to solve the yellowing problem of evergreen leaves!

Yellowing of leaves caused by long-term loss of fat

Evergreen has not applied nitrogen fertilizer or changed water for a long time, and there is a lack of nitrogen and other nutrient elements in the water, resulting in thin and yellow branches and leaves. If the hydroponic evergreen needs to be changed into new culture water in time, the rarefied mature liquid fertilizer or compound flower fertilizer should be applied gradually.

Yellowing of leaves caused by excessive fertilization

If you fertilize too much, the new leaves of evergreen will be thickened, and the old leaves will be rugged, and the dry tips of the old leaves will fall off. You should immediately stop fertilization, increase the amount of water exchange, make the fertilizer lose, or immediately pour the pot, rinse the bulb root with water and then replant it into the basin.

Yellowing of leaves caused by heat

If the flowers are placed in a high temperature place to let the strong light shine directly, it is very easy to cause the young leaf tip and leaf edge to scorch, or the leaf yellow to fall off. Move to a well-ventilated shady place in time.

Yellowing of leaves caused by excessive shading

If the flowers are kept in shade or in a place with insufficient light for a long time, it will cause the branches and leaves to turn yellow.

Yellowing of leaves caused by alkali in soil and water

Due to the lack of soluble iron and other elements that can be absorbed by the water, the leaves of evergreen will gradually turn yellow. Acid soil and water should be selected when planting, and alum and fertilizer water should be often irrigated during the growth period.

Yellowing of leaves caused by poor ventilation

If the application of too much nitrogen fertilizer, the evergreen branches and leaves grow too luxuriantly, coupled with long-term unpruned, resulting in insufficient light of the inner chamber branches and leaves, which is easy to cause the leaves to yellowing and falling off. Reasonable fertilization should be applied and pruning should be strengthened to make it ventilated and transparent.

Yellowing of leaves caused by dry air

When the indoor air is too dry, flowers often appear leaf tip dryness or leaf edge scorching and other phenomena. Attention should be paid to water spraying, plastic film cover and other methods to increase air humidity to prevent the occurrence of leaf yellowing.

Yellowing of leaves caused by improper temperature

When the room temperature is too low in winter, the flowers suffer from cold damage, which leads to the yellowing of the leaves and death in severe cases. If the room temperature is too high, the transpiration of the plant is too high, and the root water and nutrients are in short supply, the leaves will turn yellow. Please pay attention to adjust the room temperature in time.

Yellowing of leaves caused by diseases and insect pests

Leaf spot disease caused by fungi and other bacteria is easy to cause local necrosis of leaves, yellow spots or patches, serious withering and falling off of the whole leaf, yellow-green mottle on the leaves infected by mosaic virus, and harm to shell insects, red spiders and so on.

Yellowing of leaves caused by strong sexual stimulation

The use of excessive concentration of pesticides in the prevention and control of diseases and insect pests, or being polluted by toxic gases in the atmosphere, or suddenly watering cold water when the temperature is high, are easy to cause local yellowing and scorching of the leaf tip or leaf surface, or even the whole plant to die. Therefore, we should pay attention to the rational use of pesticides and try to eliminate air pollution sources. Avoid watering flowers with cold water around noon in midsummer.

The yellowing of evergreen leaves is sometimes caused by one reason, but most of the time it is caused by many factors. Therefore, a correct diagnosis should be made in order to prescribe the right medicine to the case.
