Causes of withered and yellow leaves of rich trees and their solutions

You can also know the moral of the fortune tree by its name, which symbolizes the meaning of getting rich, as well as the cat, which is favored by many people. What we are going to focus on today is the wealth tree. As some people are busy at work, there are times when they are negligent in taking care of the rich tree, which leads to the withered and yellow leaves of the rich tree, and if you want to solve the withered and yellow tree, you have to understand the causes of the withered yellow in order to better solve the symptoms of withered yellow.

Causes of withered and yellow leaves of rich trees and their solutions

I. improper watering

The reason for withering and yellowing: the rich trees like the warm and humid climate, so it is necessary to keep the basin soil moist and adhere to the principle that the basin soil is not dry and not watered when it is cultivated indoors. Because if it is not watered thoroughly and the basin soil is wet and dry, it will affect the rich tree to absorb nutrients, so that the leaves are dim, and the leaves gradually begin to wither and fall off from the bottom up.

Solution: watering as little as possible, you can choose to spray water progressively, and after the leaves slowly recover, you can carry out normal watering.

Second, the light is uncomfortable.

The reason for yellowing: the rich tree likes the light, but it can not be directed by strong light, so it is most appropriate to put it in the place of semi-shade or scattered light, and it needs to be placed in the place with light in winter, which is beneficial to the good growth of the rich tree. If the rich tree is in the shade or in a dark place for a long time, the leaves will turn yellow and wither, and if it does not move to the place with light, the plant may die.

Solution: on a sunny day in late April, move the rich tree pot to a sunny place and shine directly for an hour or two, then slowly extend the light time, which can also slowly improve the yellowing leaves.

III. Diseases and insect pests

The cause of withering and yellowing: the common disease of the rich tree is leaf spot, and the insect pests are mainly shell insects and red spiders. Leaf spot disease will slowly spot the leaves, and then slowly expand so that the leaves fall off.

Solution: leaf spot can be sterilized by spraying garlic juice, while shell insects can be prevented by wiping dust on leaves with cotton cloth, spraying wind oil essence and 0.2% washing powder solution, and drug treatment for red spiders. Mite, acaric acid, triclofenac and so on can effectively prevent red spiders.

IV. Excessive fertilizer

The cause of yellowing: if too much unripe fertilizer is applied, the imagination of burning roots will appear, which will cause the leaves to turn yellow and wither. Therefore, when applying fertilizer, we must apply the right amount of mature fertilizer regularly, and the interval between fertilization is 20 days. When changing pots, we should apply enough mature basic fertilizer, but not too much, just enough to grow rich trees.

Solution: if the soil is in a fertile state, there is no need to apply fertilizer, and for rich trees that have been raised for a period of time, you can apply a thin fertilizer, such as foliage fertilizer.

Fifth, the dust is too thick

The cause of yellowing: if there is more dust on the leaves of the rich tree, it will affect its respiration and photosynthesis, and the leaves lead to the yellowing of the leaves.

Solution: regularly use cotton cloth to wipe the dust on the leaves, the leaves are in a clean state, be careful not to hurt the leaves when wiping.

VI. Soil replacement error

The cause of yellowing: the wrong method of changing soil is also the reason for the yellowing of leaves.

The solution: when changing the soil, we should take good measures to protect the roots to ensure that the matrix is aseptic, acidic, breathable and fertile, and after changing the soil, the soil will be compacted, because if it is not pressed, there will be a gap between the soil. no matter how much water is poured, there will be a lack of water, which will make the leaves yellow.

The cause of the yellowing leaves of the rich tree how to solve the problem that the leaves of the rich tree turn yellow

The rich tree is a highly ornamental plant variety, which has been widely concerned by people all the time. Then let's take a look at how the leaves of the rich tree turn yellow. Through the study of the knowledge of the rich tree, we can better apply it to our daily life.

The reason why the leaves of the rich tree turn yellow

1. Overwatering

Some plants do not need to be watered frequently, such as rich trees. If it is often watered, the basin soil will be too wet, which will cause anoxia in the soil, make some fibrous roots rot, hinder normal respiration and absorption of water and nutrients, and cause leaves to turn yellow and fall off.

2. Drought dehydration

If the plants are not watered for a long time, the leaves will inevitably turn yellow. if the soil is not watered properly, it will not only make the soil wet and dry, but also affect the absorption of nutrients, and it is also easy to cause the leaves to be dull and dull, and the leaves wilt and droop. First, the lower old leaves aged, and gradually withered and yellowed off from the bottom up. You can water or spray a small amount of water, and then water normally when the plants return to normal.

3. Excessive fertilization

Excessive fertilization will lead to excessive nutrition of plants, the emergence of new leaves hypertrophy, and many uneven, old leaves dry tip scorched yellow shedding. At this time, you can stop fertilizing, increase the amount of water, and let the fertilizer flow out of the basin.

4. Heat, high temperature or excessive shade

Putting the wealth tree in the sun for a long time can also cause scorch on the tip and edge of young leaves, or yellow shedding of leaves. At this time, it should be moved to a ventilated and cool place.

Putting the wealth tree in shade or in a place with insufficient light for a long time will also cause the leaves of the wealth tree to turn yellow. The shade tolerance of the rich tree is strong, and it can be placed indoors for 2 or 4 weeks and then put in a sunny place, but it should not be placed in a place without sunshine for a long time.

5. Diseases and insect pests

When plants receive fungi and other bacteria will cause leaf spot disease, at this time there will be local leaf necrosis or yellow spots or patches, in serious cases will lead to withered and yellow shedding. At this time, plants should be sprayed with drugs for prevention and control.

6. The temperature is too low

The yellowing of the leaves of the rich tree is also related to the temperature. The lowest temperature of the planting environment in winter is 16-18 ℃, below which the leaves turn yellow and fall off, and the leaves are easy to die below 10 ℃. Rich trees can be watered less in winter and occasionally spray water to the page.

The leaves of the rich tree turn yellow.

First, water yellow: caused by excessive watering, which is characterized by no obvious change in old leaves and yellowing of young leaves, which should be controlled immediately.

Second, dry yellow: caused by lack of water, drought, its characteristic is from bottom to top old leaves first yellow, if the lack of water for a little longer, it will be the whole plant yellow leaves, or even death, should be timely watering.

Third, fat yellow: caused by excessive fertilization or high concentration; characterized by thick, shiny and uneven young leaves; fertilizer, ploughing and watering should be controlled.

Fourth, hungry yellow: caused by insufficient fertilizer, low fertilization concentration, and long interval of fertilization; it is characterized by yellow young leaves and tender stems, and if it is not fertilized in time after seeing this phenomenon, it will also cause yellow leaves and even death of the whole plant; for flowers that lack fertilizer, do not apply a large amount of thick fertilizer at one time, so as not to cause root burning.

Fifth, iron deficiency yellow leaves: woody flowers in greenhouse, etc., due to great changes in soil fertility conditions, yellow leaves often appear, characterized by obvious young leaves, light old leaves, yellow mesophyll, green veins, and forming a typical network; ferrous sulfate solution can be used to solve the problem, the method is as follows: 7 parts of cake fertilizer, 5 parts of ferrous sulfate and 200 parts of water.

The causes of the yellowing of the leaves of rich trees and the solutions

1. Improper watering: the rich tree likes the warm and humid climate, and the basin soil should be moist, but the pot soil is generally not dry and watered thoroughly 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. 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. If you stay in the shade or dark for a long time, there will be yellowing and defoliation of leaves, and in serious cases, it will also appear.

3. Disease and pest control: leaf spot is a common disease of rich trees, the symptom is that a few spots appear at first, then the spots gradually expand and extend to the whole leaf, and fall off, and can be sterilized with garlic juice. In terms of insect pests, there are mainly red spiders and shell insects. Red spider individual is small, the body length is less than 1 mm, can use mite net, acaroid, triclofenac and so on to carry on the effective control. The individual scale insects vary from species to species and vary in color, but they have a common feature, that is, they are round or oval, generally do not move, suck juice close to the stem or petiole of the plant, and can be wiped clean with strips of cloth, because the scale insects die as soon as they leave the plant, and 0.2% solution of essential oil and washing powder can be sprayed for prevention and control.

4. Too much fertilizer: in general, in the period of suitable temperature for the growth of the rich tree, regular fertilization should be applied to ensure the luxuriant growth of the plant. Generally, thin fertilizer should be applied once in about 20 days, and rotten base fertilizer should be added when changing the basin. 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. Dust on the leaves: if the dust on the leaves is too thick, it will not only affect the appearance, but also affect the respiration and photosynthesis of the plants, resulting in yellowing of the leaves. Dust should be wiped clean in time.

6. Error in soil exchange operation: when changing soil, incorrect 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 environmental temperature: the rich tree likes the warm and humid environment. The suitable temperature for its growth is 20-30 ℃. If the temperature is lower than 18 ℃, the rich tree can stop growing, and 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 scattered, and the heavy ones will die.

8. Hot and high temperature: for wealth trees that are sexually fond of warm and humid environment, if exposed to high temperature, the transpiration of the plant is too high, and the root water and nutrients are 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. No ventilation: if the branches and leaves of the rich tree grow too luxuriantly and have not been pruned for a long time, the inner branches and leaves of the rich tree are not bright enough, which can easily cause the leaves to yellowing and falling off, so that the pruning should be strengthened in time to make it ventilated and transparent.

10 soil and water alkalinity: the soil and water in most northern areas contain more salt and alkali, which is not suitable for planting acidophilic rich trees. Because of the lack of iron elements 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.

The above is the relevant introduction of this article, I believe you have a simple understanding of this after reading it, if necessary, you can continue to pay attention to the No. 1 home network to learn more information.

What if the leaves of the rich tree turn yellow? Causes and solutions

The rich tree is also known as Malaba chestnut, melon chestnut, goose palm money, etc., which means that raising this tree means making a fortune, so many people are willing to plant such a tree at home. In this fast-paced life, not everyone has so much time to take care of these plants, so it will also get sick and show symptoms such as yellowing leaves. Let's take a look at how the leaves of the rich tree turn yellow.

Improper watering

[reason] the rich tree likes the warm and humid climate, 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, if it is wet and dry, it will affect the absorption of nutrients, resulting in dull and dull leaves, and gradually wither and fall off from the bottom up.

[method] improper watering leads to the yellowing of the leaves of the rich tree, which needs a small amount of watering and often sprayed, so that it can gradually recover and then turn to normal watering.

Light discomfort

[reason] Fortune trees like light, but can not tolerate strong direct light. Semi-overcast or scattered light is suitable. Only better light conditions are needed in winter to grow well. For a long time in the shade or dark places, there will be leaves yellowing, defoliation phenomenon, serious cases will also die.

[methods] 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.

Disease and insect damage

[cause] Leaf spot is a common disease of rich trees, the symptom is that a few spots appear at first, then the spots gradually expand and extend to the whole leaf, and fall off. In terms of insect pests, there are mainly red spiders and shell insects.

[methods] Leaf spot disease can be sterilized by spraying garlic juice, red spiders can be effectively controlled with mite, acaroid, triclofenac, etc., and shell insects can be wiped clean with cloth strips when they are rare. 0.2% solution of essential oil and washing powder can be sprayed for prevention and control.

Too much fertilizer

[reason] the rich trees should be fertilized regularly during the suitable temperature period to ensure the luxuriant growth of the 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.

[methods] the rich trees do not need to apply fertilizer when the soil is fertile enough. If they have been raised for a long time, consider giving them thin fertilizer, avoid thick fertilizer, and use some common foliage fertilizer. Remember to use thin fertilizer.

Dust is too thick

[reason] the dust on the leaves of rich trees is too thick, which not only affects the beauty, but also affects the absorption and photosynthesis of the plants, resulting in yellowing of the leaves.

[method] the dust should be wiped clean in time.

Soil replacement error

[reason] the improper operation of the rich tree when changing the soil will also cause the leaves of the rich tree to turn yellow.

[methods] when changing the soil for the rich tree, the roots should be hurt 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 of leaves.

The temperature is too low

[reason] the rich tree likes the warm and humid environment, the suitable temperature for growth is 20: 30 ℃, the temperature is lower than 18 ℃, the rich tree can stop growing, and 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.

[method] move the wealth tree to a place with high indoor temperature in time.

The temperature is too high

[reason] if the rich trees in the warm and humid environment are exposed to high temperature, the transpiration of the plant is too high, and the water and nutrients in the roots are in short supply, which can easily cause leaf tip scorching or leaf yellow shedding.

[method] move the wealth tree to a well-ventilated shady place in time.

Poor ventilation

[reason] if the branches and leaves of the rich tree grow too luxuriantly and have not been pruned for a long time, the inner branches and leaves of the rich tree are not bright enough, which can easily cause the leaves to yellowing and falling off.

[methods] pruning should be strengthened in time to make it ventilated and transparent.

Soil and water partial alkali

[reason] the soil and water in most areas of the north contain more salt and alkali, so it is not suitable to plant acidophilic 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.

[methods] attention should be paid to the selection of acidic soil when planting, and alum fertilizer and water should be often irrigated during the growth period.
