What if the leaves of the mulberry flowers turn yellow? pay attention to the yellowing at 5 o'clock. / lack of light and fertilization is too little.

As a good product of indoor culture, Fusang flower is favored by many flower friends because of its beautiful shape and bright red color, and keeps it at home. However, in the process of breeding, due to improper maintenance and other problems, the plant will appear symptoms of yellow leaves, then how to do the leaves of mulberry flowers yellowing? The following are the reasons for the yellowing of the leaves of five kinds of mulberry flowers sorted out by the editor. Let's go and have a look.

First, how should the leaves of Fusang flowers turn yellow? find the cause.

In the culture method of Fusang flower, we introduced the requirements of light, water, fertilizer and fertilization of Fusang flower, and once we can not meet it, its leaves will turn yellow. As for the yellowing of Fusang flower leaves, we should first find the cause, and then solve the problem. The following are the five reasons for the yellowing of mulberry leaves summarized by the editor, and the solutions are attached. Let's move on.

II. Causes of yellowing of Fusang flower leaves and its solutions

1. Environmental mutation

Any plant, no matter how adaptable it is, its leaves will turn yellow once its growth environment changes too much. So if you buy the mulberry flowers from the Internet, it may not adapt to the great changes in the growth environment, and there will be symptoms of yellowing leaves after a period of time.

Solution: communicate with the shop owner to understand the growth environment before Fusang flower, we strive to keep the same at home, and then gradually change until it becomes the current environment. After a period of time, the Fusang flowers of the detailed flower friends will return to health.

2. Lack of light

In the breeding process of Fusang flower, light is extremely important, we need to give it enough light. Once the light of the mulberry flower is insufficient, or if we put it in a dark place for a long time, the symptoms of yellowing leaves will appear.

Solution: give Fusang enough light time, if placed indoors, it is best to choose sunny places, such as balconies, windowsills, courtyards and so on.

3. Overwatering or lack of water

There are many reasons for the yellowing of Fusang flower leaves, but the most likely one is improper watering. It is understood that Fusang likes water but is not resistant to waterlogging and is afraid of drought, so it is no good to water too much or too little, which will cause leaves to turn yellow and fall leaves.

Solution: water too much, immediately stop watering, it is best to loosen the soil, let the water evaporate; watering too little, in order to prevent water loss, immediately put the mulberry flowers in the semi-shade, and slightly water, not more than one time. At the same time, the strong gap in the basin wall is loosened to drain water from the gap.

4. Lack of fertilizer

In the growth process of Fusang flower, proper fertilization is very important. Once we do not apply fertilizer for a long time, or do not apply fertilizer at all, the leaves of Fusang flowers will turn yellow because of the lack of necessary nutrients.

Solution: fertilize the mulberry flowers at the right time: only when the weather is less than 30 degrees can we fertilize. It is best to apply fertilizer once a week to ensure blooming.

5. Pest attack

In the breeding process of Fusang flower, diseases and insect pests are easy to appear, and once there are white whitefly, shell insects and other pests, the Fusang flower will appear the phenomenon of leaf yellowing and even shedding.

Solution: what kind of pest it is, and then spray it with medicine. As for what kind of medicine to use, there is a detailed introduction to the pest control species of Fusang flower, so I won't say much here.

Generally speaking, Fusang flowers are relatively easy to raise, but in the process of breeding, if they are not left, their leaves will turn yellow, thus seriously affecting the ornamental. Therefore, now that we have raised it, we should be careful and keep it well. This is the best way. With regard to the yellowing of the leaves of Fusang flowers, the editor has introduced this, hoping to give you some help.

What if the leaves of the mulberry flowers turn yellow? The reason why the leaves of mulberry flowers are yellowing is that mulberry flowers are prone to bud drop, which is caused by improper maintenance, resulting in the imbalance of nutrition supply in the plant. Fusang is a strong positive flower, sexual love sufficient sunshine, such as long-term overcast, lack of light, while watering too much, basin soil in a wet state, it will cause rotten roots, leading to fallen leaves, buds.

Fusang flower leaves yellowing how to do 1, Fusang flower leaves yellowing: unreasonable watering lack of water or too much watering, will have adverse effects on the growth of Fusang flowers. Fusang likes water but is not resistant to waterlogging and is afraid of drought. no matter it is waterlogging or drought, it will cause leaf yellowing and shedding. Watering too much, the basin soil is in a wet state, it will cause rotten roots, leading to fallen leaves and buds. Solution: so watering should adhere to the basin soil surface dry watering is conducive to good plant growth, the emergence of waterlogging may also be the reason for too much Rain Water. Therefore, flower friends in this situation can recall their usual habit of watering. If they are watered properly, is it because there are too many Rain Water? If the pot is small and the seedlings are large, when the high temperature evaporates quickly in summer, the watering frequency should be increased appropriately.

2. Fusang flower leaves yellowing: lack of necessary nutrients (lack of fat yellow) solution: Fusang flowers are considering topdressing fertilizer when the weather is below 30 degrees. The application of cake fertilizer once a week can ensure flowering and flourishing. 3. Fusang flower leaves yellowing: lack of light (lack of light yellow) solution: Fusang flower is a strong positive plant, requiring the growth environment of all-yang, such as long-term overcast, lack of light, it will lead to the phenomenon of yellow leaves and even leaves falling off. 4. Fusang flower leaves yellowing: potted mulberry pots should not be too large, generally using a 15-centimeter earthen pot, and then releasing the soil year by year. The potted soil uses sandy loam rich in organic matter, mixed with 10% mature cake fertilizer or dry dung. Just planted seedlings, the soil should be compacted, watered, shaded for a few days, after the slow seedling and then moved to a sunny place to cultivate, conducive to survival, usually pay attention to moderate watering, too moist affect flowering. 5. Fusang flower leaves yellowing: suffering from insect pests (disease yellow) if there are diseases and insect pests, it will also cause leaf yellowing and shedding, such as red plants, whitefly and shell insects. 6. The solution to the leaf yellow caused by insect pests: a, the red spider mainly harms the back of the leaf, and it is found that the whole plant can be sprayed with mites after washing with heavy water, such as mites, mites, etc.; b, whitefly mainly parasites on the back of the leaf, piercing into the mesophyll to suck its juice, making the leaves curl, turn green and yellowing, and even dry and fall off. During the occurrence of whitefly, spray with 1500 to 2000 times of 25% prolactin wettable powder, spray again 15 days later, or spray 10% imidacloprid 2000 times, as long as the adults and nymphs are killed, as the future increase ventilation, repeated water spray can wash away honeydew, etc., and the dirty mildew layer will soon fade away. Under the condition of family cultivation, when the adults fly randomly, we can try to spray the mosquito net, knock down the adults at one fell swoop, and then gently wipe off the mold layer with a wet cloth to strengthen the management of water and fertilizer, and the plant can recover quickly. C, the scale insect mainly harms the stem, petiole and so on, with different size and color, round and oval in shape. Shell insects can be wiped clean with a toothbrush or a dishcloth, or can be sprayed with 0.2% solution of detergent and essential oil, or pesticides such as methamphetamidophos, with good results. What if the leaves of Fusang flowers turn yellow? what about the curls of Fusang flower leaves?

In the cultivation of mulberry flowers, we will encounter yellow and curly leaves, what should we do? Let's have a look with us next.

The reason for the yellowing of Fusang flower leaves:

One: lack of light

Fusang is a strong positive plant, sexual preference for plenty of sunshine. If it is kept in a shady place for a long time, it will easily lead to the phenomenon of yellow leaves, as well as the shedding of buds and dim color of flowers. Therefore, it is necessary to ensure more than 8 hours of light every day, and pay attention to proper shading when it is hot in summer.

Second, improper watering

If the mulberry is overwatered and the basin soil is in a wet state, it will cause rotten roots, resulting in fallen leaves and buds. However, if too little watering, drought during bud pregnancy, will also cause old leaves yellowing and shedding, buds are also easy to detach and fall off. Especially during the indoor overwintering in winter, the room temperature is low and the mulberry is in a dormant state. if it is watered too much at this time, it is most likely to cause rotten roots and fallen leaves. Therefore, Fusang is usually watered once a day when it is drier, the water should be watered thoroughly, and the air humidity should be increased by spraying water, but watering needs to be reduced in winter.

Solution:

If the leaves have yellowed, the potted plants should be transferred from the indoor to the indoor semi-overcast environment in time. The pots should be watered in time when the pots are dry, stop fertilizing, and sprinkle water on the page several times at noon every day to ensure sufficient water.

After the temperature drops to 5 degrees after winter, it will be moved to indoor maintenance to keep warm. In the meantime, if Fusang continues to lose its leaves, don't worry, as long as the stem turns green, and pay attention to watering the pot soil after drying, Fusang will send out tender new leaves next spring.

The reason for the curl of Fusang flower leaves:

1, summer and autumn to buy back without a pot of Fusang flowers, due to the growth of flowering, root injury, coupled with high temperature, but also cut off water, often appear leaves curling and sagging, and even yellowing causing shedding.

2. Fusang flowers are strong positive plants, which like warmth and moisture, and require sufficient sunlight, no shade tolerance, cold and drought tolerance. In the Yangtze River valley and the north of China, they can only be potted and keep the temperature of 12 ℃-15 ℃ in greenhouse or other protected areas to survive the winter.

When the room temperature is lower than 5 ℃, the leaves turn yellow and fall off, and when the temperature is less than 0 ℃, they will suffer frost injury. Resistant to pruning and strong branching.

3. It has a wide range of adaptation to soil, but the slightly acidic loam rich in organic matter and pH6.5-pH7 grows best.

4. Fusang flowers are positive tree species, which should be moved outdoors and placed in a sunny place at the beginning of May, which is also the growing season of Fusang mulberry, so it is necessary to strengthen the management of fertilizer and water, loosening soil, pulling grass and so on. Apply dilute liquid fertilizer every 7-10 days, watering should depend on the dry and wet condition of the basin soil, too dry or too wet will affect flowering.

5. if the light is insufficient, the buds are easy to fall off, the flowers are shrinking, and the sunshine should not be less than 8 hours a day.

6. Fusang has a great demand for fertilizer, so it is necessary to replenish light in time in cultivation.

7. Potted mulberry plants generally go out of the house in April, change pots before leaving the house, and trim them properly to maintain a beautiful crown. During the growing period, they should be well watered, and they should not be watered or waterlogged. They are usually watered once a day, but once in the morning and evening in the summer days. The ground is often sprinkled to moisturize and cool down to prevent young leaves from scorching and flowers from falling early.

Preventive measures for leaf curling of mulberry flowers:

The main results are as follows: 1. Move to the outdoor semi-shade place as soon as possible, water in time, sprinkle water on the leaf surface several times before and after noon, in order to reduce the evaporation of leaf water, and should suspend fertilization, wait for the pot to gradually restore vitality.

2. After the beginning of winter, when the temperature drops to 5 ℃, it should be moved into the room to prevent freezing and keep warm. During this period, Fusang will not grow new leaves, and the old leaves will turn yellow and fall off, but as long as the branches are green and the potted soil is dried and watered and carefully maintained, new leaves will grow again in the second spring.

3. One may be caused by aphids, which can be found on the back of the leaves and can be treated with 1000 times omethoate, and one may be infected with the virus, which may be curled, wrinkled and mosaic.
