What if the leaves of the rich tree turn yellow? the right cure is the right cure.

After planting and cultivating the rich tree for a period of time, the leaves turn yellow, which affects the appearance and mood. So, what if the leaves of the rich tree turn yellow? It is said that there are as many as 10 reasons for the yellowing of the leaves of the rich tree, and if drugs are used indiscriminately, the problem of yellowing of the leaves of the rich tree may not be solved.

It can be said that the yellowing of the leaves of the rich tree is also a common situation, which is closely related to improper nursing in the process of planting and breeding.

1. Improper watering

The rich tree likes the warm and humid climate environment, and the basin soil should be moist, but the pot soil is generally not dry and irrigated in indoor cultivation. Because, if it is not watered thoroughly, it will affect the absorption of nutrients, resulting in dull and dull leaves, and gradually wither and fall off from the bottom up. In this case, a small amount of water is needed and often sprayed to make it gradually recover and then turn to normal watering.

2. Light discomfort

Rich trees like light, but can not tolerate strong direct light, and semi-overcast or scattered light is suitable. Only better light conditions are needed in winter to grow well. Starting from late April, you can choose a sunny noon, move the basin out of the outdoor or balcony, directly see the sun for 1-2 hours, and gradually extend the time, there will be a good breeding effect. For a long time in the shade or dark places, there will be leaves yellowing, defoliation phenomenon, serious cases will also die.

3. Disease and pest scourge

Leaf spot is a common disease in rich trees. Garlic juice can be used for spray sterilization. In terms of insect pests, it is mainly the harm of red spiders and shell insects. To deal with red spiders, mites, acaroid mites and triclofenac can be used for effective control. On the other hand, for shell insects, you can wipe them clean with strips of cloth, because they will die as soon as they leave the plant; often, 0.2% solution of wind oil essence and washing powder can be sprayed to control them.

4. Too much fertilizer

In the period of suitable temperature for the growth of rich trees, regular fertilization should be applied to ensure the luxuriant growth of plants. Generally, thin fertilizer should be applied once in about 20 days, and rotten base fertilizer should be added when changing pots. If the fertilizer is applied too much, or the fertilizer is not mature, it will cause the rich tree to burn its roots and cause the leaves to turn yellow and fall off.

5. There is dust on the leaves.

If the leaf dust is too thick, it will not only affect the appearance, but also affect the respiration and photosynthesis of the plant, resulting in yellowing of the leaves. Dust should be wiped clean in time.

6. Soil replacement operation error

When changing the soil, improper operation will also cause the leaves of the rich tree to turn yellow. When changing the soil for the rich tree, it is necessary to hurt the roots as little as possible, the added matrix should be aseptic, breathable, fertile and slightly acidic, and the basin soil should be filled with no space. If there is a gap, the plant will be irrigated with more water, or the phenomenon of water shortage will occur, resulting in yellowing leaves.

7. Low ambient temperature

The rich tree likes the warm and humid environment. The suitable temperature for its growth is 20-30 ℃. If the temperature is below 18 ℃, the rich tree can stop growing. The temperature as low as 10 ℃ can adapt, but the lowest temperature can not be lower than 5 ℃. Otherwise, freezing injury will occur, the light ones will be yellow, and the heavy ones will die.

8. Hot and high temperature

For wealth trees that like warm and humid environment, if they are exposed to high temperature, the transpiration of the plant will be excessive, and the root water and nutrients will be in short supply, which can easily cause leaf tip scorch or leaf yellow shedding, which should be moved to a cool place with good ventilation in time.

9. Whether it is airtight or not

If the branches and leaves of the rich tree grow too luxuriantly, coupled with the lack of light in the inner chamber branches and leaves for a long time, it is very easy to cause the leaves to yellowing and falling off, so that the pruning should be strengthened in time to make it ventilated and transparent.

10. Deviation of soil and water

In most areas of the north, the soil and water contain more salt and alkali, so it is not suitable for planting acidity-loving rich trees. Because of the lack of iron that can be absorbed by them in the soil, the leaves of rich trees will gradually turn yellow. When planting, we should pay attention to the selection of acidic soil, and often pour alum fertilizer and water during the growth period.

Rich trees are planted indoors, and their growth environment has changed. Therefore, we need to create a suitable growth environment for them. This is the root of preventing the yellowing of the leaves of the rich tree.
