What is the reason why the whole leaf of the fortune tree has brown spots?

It may be that you have macular disease, so you can go to the flower shop and buy medicine and spray it.

The leaves of the fortune tree have chloasma, which may be leaf blight or leaf spot. Leaf blight and leaf spot are caused by fungi and are mainly related to the way they are maintained. During the maintenance period, after the fortune tree has leaf blight and leaf spot disease, it needs to prune the diseased leaves, and then spray the fortune tree with relevant pesticides, which can effectively inhibit the disease.

During the maintenance period, the leaves of the fortune tree have chloasma, which may be due to leaf blight. During the maintenance period, if the maintenance method is not appropriate, the growth of the fortune tree will deteriorate and be infected by the pathogen, it will get leaf blight, which will make the leaves grow chloasma. During the maintenance period, if the fortune tree has leaf blight, it is necessary to cut off the diseased leaves of the fortune tree in time.

After pruning, the tree can be sprayed with carbendazim, chlorothalonil or methyl tobuzin. After diluting the agent with water, generally about 7 10 days, you can spray the fortune tree 1 time, and after spraying 2 3 times in a row, you can control the leaf blight. During the maintenance period, it should be placed in a cool and ventilated location, which is conducive to the recovery of the fortune tree.

During the maintenance period of the fortune tree, there are chloasma on the leaves, which may also be a leaf spot disease. During the maintenance period, excessive watering or fertilization, after the root system of the fortune tree is damaged, it will be infected with germs, and later get leaf spot disease. After the fortune tree has leaf spot disease, the leaves will develop chloasma, and if it is not treated in time, it will affect the normal growth of the fortune tree in the later stage.

During the maintenance period, after the tree has leaf spot, the diseased leaves need to be pruned and burned. After treating the diseased leaves, you can place the fortune tree in a cool and ventilated place indoors, and spray the fortune tree with methyl tobuzin or chlorothalonil regularly. It is necessary to pay attention to the concentration of the agent, if the concentration is too high, the fortune tree will be damaged by the medicine in the later stage.

If the leaves of the fortune tree have melasma, it is necessary to change the environment, spray pesticides, and replenish water.

When the leaves of the fortune tree have melasma, it should be immediately moved to a shading and ventilated place to avoid the leaves of the plant being exposed to direct light, and at the same time, it is necessary to open windows for ventilation for the fortune tree to maintain air circulation, reduce the speed of the spread of the disease, and prevent other healthy leaves from suffering from diseases.

After the fortune tree changes the environment, it is necessary to use carbendazim or chlorothalonil agent for it, spray it on the surface of the diseased leaves for treatment, pay attention to spraying, use a sprayer with small holes, so as to spray the agent evenly on the leaves.

When the melasma on the leaves of the fortune tree disappears, it is necessary to observe the state of the soil, and when the surface of the soil is dry and there are signs of whitishness, it is necessary to water the fortune tree immediately to make the moisture in the soil between 60-70%, and at the same time spray water mist on the leaves of the fortune tree to replenish water for the leaves.

How to properly maintain the Fortune Tree

The root system of the fortune tree is well developed, suitable for growing in loose soil, if the soil is compacted, it is easy to cause its roots to breathe poorly, and there is rot, so in the breeding process, it is necessary to loosen the soil and change the pot every 2 years, and the pot and soil are suitable for ventilation.

The branches and foliage of the fortune tree are luxuriant, and it is necessary to pay attention to the pruning of the branches and leaves in time when breeding, so that it maintains a good plant shape, after the fortune tree grows to a certain height, it is necessary to pluck the top, control the growth height, and usually prune the stump and diseased leaves and thin old branches.

When cultivating the fortune tree, it is also necessary to pay attention to providing it with sufficient light for the rock foot, so that the plant can carry out photosynthesis normally, so as to grow healthily, and can accept full sunshine in spring, autumn and winter, but in summer it should be shaded with a shade cloth to avoid direct sunlight.

Reasonable supply of nutrients for the fortune tree, in order to make the plant grow better, generally in its growth period to apply a thin nitrogen fertilizer solution at an interval of about 20 days, so that the leaves are more vigorous, green, but in the fertilization should not be excessive, to prevent the thick fertilizer from burning the roots.

It is very likely that the cause of infection with leaf spot disease can be cut off from the diseased leaves, strengthen ventilation, and then spray carbendazim, chlorothalonil, methyl tobuzin and other agents on the leaves, spray once every 10 days or so, and it can be prevented and treated soon.

1. Prevention and treatment methods of leaf spot.

If it is determined that it is caused by the leaf spot of the fortune tree, some brown spots will appear on the leaves, and these spots will gradually become larger, and the leaves will gradually turn yellow. Move the plants to a location where the humidity is not particularly high and the ventilation conditions are relatively good. Then cut off the diseased leaves and spray a 5% carbendazim solution to get rid of the germs.

2. Maintenance of the Fortune Tree.

1. Watering. Watering the fortune tree should be determined according to the season and environmental temperature, under normal circumstances, the temperature is high in summer, the water evaporates quickly, so the wealth tree needs more water, you can water it several times a week, but pay attention to the watering time do not appear waterlogged.

Fortune tree in the winter will enter the dormant period, pay attention to appropriately reduce the number of watering, under normal circumstances, about half a month or about 20 days to water once, in the spring and autumn season can be watered once a week or ten days according to the ambient temperature.

2. Fertilization. Fortune tree is a kind of fertilizer-loving flowers, in the growth period to apply nitrogen, phosphorus, potassium fertilizer, or rotten organic fertilizer, fertilization to a small amount of many times, in case the fertilizer is too large to burn the roots, when applying organic fertilizer to use well-rotted fertilizer or the selection of ribery Yanwo water-soluble fertilizer, for the sake of safety, pay attention to the dilution after fertilization.

Third, the soil preparation should be reasonable.

To maintain the water of the fortune tree, it is necessary to pay attention to looseness and air permeability, and it is best to choose the proportion of garden soil, humus soil and sandy soil.

Exposure to the sun, improper watering.

1. Exposure to the sun. We all know that indoor potted wealth trees should not be exposed to the sun for a long time, once exposed to the sun for a long time, the leaves will be burned by the sun, and some white spots will appear, which are difficult to disappear and return to normal in the later stage. Moreover, the longer the sun is shined, the larger the area of white spots will appear, which directly affects the growth of ornamental and fortune trees.

Resolution. If the leaves are whitish due to sunburn, you can cut off all these whitish leaves and let them grow new leaves, so that the overall appearance will be better. If not cut, these whitish leaves are also difficult to recover. And the fortune tree should also be moved to a place where there is no sun exposure, or directly close the curtains and cover it with a sunshade net to prevent the fortune tree from being directly exposed to the sun.

2. Improper watering.

When the fortune tree is overwatered, the root system is damaged, if the situation is not very serious, it will not immediately yellow leaves, but the tips of the leaves will first turn brown, and slowly the whole leaves will dry up and turn white; In addition, if you do not water for a long time, the potting soil will be too dry, and the tree will not be able to absorb nutrients, and the root system will also be damaged due to drought, resulting in the upper leaves appearing dry and white.

Resolution. Improper watering causes the leaves of the fortune tree to dry and white, and it is necessary to analyze whether it is caused by too much watering or caused by excessive potting soil. If the potting soil is too wet, it is necessary to ventilate more to dissipate the water in the potting soil as soon as possible, and the fortune tree will slowly ease up in the later stage. If the potting soil is too dry, then it is necessary to soak the potting soil to allow the roots to regain their vitality.

It is usually better to water the fortune tree when it is dry and thorough, not too much and not too dry, no matter which extreme will cause adverse consequences.

3. Diseases. Long-term indoor wealth tree, poor ventilation conditions and stuffiness, wealth tree is prone to some diseases, such as leaf spot, after the onset of the leaf will appear some spots, round or irregular shape, some are brown, some are white. And these lesions can spread and damage other normal leaves.

Resolution. If the leaves of the fortune tree are whitish due to disease, then the diseased leaves should also be cut off, and then transferred to a well-ventilated location for maintenance, and then assisted by the use of carbendazim, chlorothalonil and other fungicidal agents to spray the leaves, so as to eliminate the possible residual germs and avoid the germs from continuing to harm the leaves.

4. Top dressing of fortune trees.

Although the root system of the fortune tree is relatively weak, the branches and leaves are generally very lush. Therefore, fertilization can be carried out through leaves, and in the peak growing season, foliar fertilizer is sprayed on the foliar surface of the branches and leaves, and there is no fear of rotting roots without going through the root system. The fortune tree is a leafy green plant, and the best foliar fertilizer is nitrogen fertilizer and compound fertilizer.

For example, urea, ribery, Yanwo amino acid foliar fertilizer, etc., take a certain amount and fully dissolve, and spray it evenly on the leaves, which can be well absorbed.

1. The leaves of the fortune tree have black spots, because they are infected with the fungal disease of socks, and the infected leaves can be sterilized and disinfected, and the diseased leaves and branches that are too serious can be cut off, and then watered with Tobujin or chlorothalonil.

2. How to maintain the fortune tree.

1) Pay attention to fertilization in summer maintenance of the fortune tree, the fortune tree is a fertilizer-loving plant, so it is generally recommended to apply nitrogen, phosphorus and potassium fertilizers in summer, and it is advisable to fertilize once every 30 days.

(2) Fortune trees don't like to accumulate water, so you should pay attention not to water too much in summer, and the watering principle is to dry and water thoroughly.

3) In summer, the temperature is light and the sun is strong, so it is recommended to keep the fortune tree in a place with scattered light, and pay attention to maintaining ventilation.

4) If you want the fortune tree to grow well, you should also pay attention to pruning in time, reduce the branches and leaves that grow more prominently at the top, and avoid the advantage of the top.

5) Because of the high temperature in summer, in order to avoid the temperature difference between water temperature and room temperature from harming the root system, it is generally recommended to choose a relatively low temperature for watering in the morning or evening.

(1) Specific reasons: There is mainly a disease that can cause this phenomenon, called "leaf spot disease", and friends who have raised plants must have heard of it. This disease is easy to identify, and if there are some spots on the leaves that are very dark at the edges, and then they slowly expand and infect other plants around them, then it is usually the disease.

2) Solution: First, of course, the diseased leaves must be cut and disposed of, and the scissors should be sterilized. After that, the liquid is sprayed.

Different situations require different types of spraying. If the symptoms are mild, carbendazim can be sprayed. If the symptoms are very severe, then chlorothalonil should be sprayed, and the rest will not work.

Just spray it every half month. Attention should also be paid to the subsequent maintenance. For example, don't make the environment too airtight and ventilate.

In addition, there should not be much moisture. Liquid fertilizer should be used once or twice a month to increase the nutrients in the soil.

1) Specific reasons: Specifically, there are three main types of the following at the same time or one is particularly serious. The first is that there is too much moisture; The second is that the light is too strong; The third is that the temperature is too low.

2) Solution: If you are not sure which is the problem, then you must first observe the surrounding environment, which link has the problem, and then adjust accordingly. In addition to this, you should also be careful not to get tea, coffee, milk, etc. in the soil, which can easily breed diseases and insects.

The leaves of the fortune tree are yellow and spotted, probably because of leaf spot, at this time, its diseased leaves should be cut off and sprayed with some 5% carbendazim to sterilize. It may also be due to leaf blight, at this time the diseased leaves should be cut off, then moved to a ventilated place, and sprayed with some chlorothalonil solution.

If the maintenance site is exposed to prolonged, intense sunlight, it may be burned. The leaves will be yellowed and burn spots will also appear. Treatment: Move to a location where the sun is not particularly strong, slowly maintain it for a period of time, and wait for it to recover.
