Gree begonias roll up the leaves, and then drop the leaves, what s going on?

Lige Begonia is a flowering plant suitable for winter maintenance, many flower friends will raise a pot at home, Lige Begonia is as cute as a rose when it blooms. However, it is not easy to raise Lige begonias, Lige begonias are particularly prone to leaf curl, and when encountering Lige begonia leaves curling downward, flower friends should not take it lightly, because this is likely to be caused by pests and diseases, and can be prevented with 5 methods.

One. Enhanced ventilation can prevent pests and diseases, so that the leaves of the begonias will no longer roll

Lige begonia is a kind of potted flower with high ventilation requirements, if the ventilation is not good, Lige begonia may have aphids at the same time. Various insect pests such as red spiders, which can move on the back of the leaves of the begonia, causing the leaves to curl. Flower friends should pay more attention to ventilation when maintaining Lige Begonia indoors in winter, but don't be too close to the tuyere when opening the window, because Lige Begonia is more afraid of cold, and it is easy to get frostbite when the cold wind blows, and some of the overly dense leaves should be removed, otherwise it will affect the ventilation.

If you can't open the window, you can put a small fan near the Lige Begonia and blow it for a while every day to ventilate the Lige Begonia.

Two. Spray fungicides on Lige begonias regularly to prevent diseases

Lige Begonia is not only easy to have insect pests, but also easy to produce various diseases, when flower friends change the soil for Lige Begonia, you can mix some carbendazim powder in the soil, usually you can spray carbendazim solution sterilization and disinfection to Lige Begonia once a month or so, to prevent Lige Begonia from producing diseases, so that Lige Begonia leaves are no longer curled.

Three. Wipe the leaves with white vinegar to eliminate the insect eggs on the leaves and improve the curling of the leaves

There is also a situation that flower friends can't see the insects on the leaves of Lige Begonia, but the leaves are curly, and this situation is likely to be that the eggs are lurking on the back of the leaves, and they have not grown up and explodedFlower friends can prepare a white vinegar solution with a concentration of 15 to 20 percent, dip cotton in vinegar solution, and wipe the back of the leaves of Lige Begonia little by little, which can effectively prevent the outbreak of insect pests and improve the leaf curling.

Four. Spray the leaves with alcohol to disinfect and sterilize to eliminate minor pests and diseases

Alcohol has a good sterilization and disinfection effect, even if the plant is free of pests and diseases, occasionally spraying a little can also play a sterilizing roleIf flower friends find that Lige Begonia has slight pests and diseases, you can spray 75% of the alcohol solution for sterilization many timesIf the pests and diseases are more serious, only drugs can be used.

Five. Spraying of drugs ** pests and diseases

Whether it is a disease or a pest, prevention is always more important than the first, because pests and diseases will bring some damage to the plant, and spraying is not good for the human body, but the flower of Lige Begonia is easy to stop once a large area of pests and diseases outbreaks, so flower friends can only use drugs after finding that the pests and diseases are more serious, and general diseases can be used chlorothalonil. Methyl tobuzin and other drugs**, insect pests can be used to protect the flower god and other drugs**, spraying is best to choose a sunny day, spraying once every two or three days, spraying three to five times in a row, general pests and diseases can be cured.

When there is a situation of rolling leaves and then falling leaves, the owner should pay attention, maybe your family's gree begonia is targeted by pests, then you can try the following methods:1Put the begonia in a place with good ventilation conditions, and a good ventilation environment can effectively prevent pests2

Regularly spray the flowers with pesticides3If there is white vinegar, you can use white vinegar to wipe the leaf surface for disinfection and sterilization, which can effectively prevent pest eggs.

Probably due to lack of water. Drink plenty of fluids in a timely manner. But don't overhydrate and let the water accumulate in the peng, and keep it indoors so that it is not affected by the wind. Moderate amount of fertilizer can be used without too much.

In fact, one of the main reasons for the fall of leaves is water imbalance, if the amount of water is too large, the potting soil is too wet, the base of the branch will breed bacteria, which will lead to rot

The leaves have insect pests and diseases, and the potting soil can be caused by excessive alkali absorption, leaf rolling, and defoliation. Due to the high temperature and humidity during the growing season, the potting soil is overwatered. In the growing season, it is the peak growth period of Geli Begonia in summer, and all insect pests multiply rapidly in large numbers, harming the leaves, absorbing the sap of the leaves, making the leaves curl and fall leaves. Wait a minute.

The first thing to look at is whether there is less water, and the most prominent feature is that the top of the plant begins to gradually wither downward, which is very common. There are two ways to solve the problem, it is best to do it at the same time, the first is to replenish the pot in time to make it sufficiently hydrated. Second, sprinkle the leaf with some water to make it recover faster, but don't use cold water at high temperatures.

In fact, too much watering will also cause its leaves to curl, so this situation should also be noted. First of all, take a look at the pot, if you notice stagnant water, you should pay attention, this is likely to be the cause of the problem with the leaves. First, keep the plant indoors, away from wind and sun, and cut off some of the leaves.

Remove part of the soil in the pot properly and replace it with dry soil, and after about ten days, the plant will return to normal, and you should pay attention to it later.

If there is too much fertilizer in the soil, it will cause the water of the plants to penetrate outward, which is also very serious and may cause the plants to wilt, so be vigilant. First, wash the potting soil with clean water and drain the excess water in time. Or remove a part of the soil and replace it with a normal one.

In order to restore the plant in a timely manner, the leaves should also be hydrated at the same time to protect the main parts of the plant.

If it is not the above situation, it is necessary to pay attention to whether the plant is diseased or infested by insects. Especially the roots, it is necessary to take care of them, and use drugs in a timely manner, and remove the parts that have already developed the disease.

Too strong wind and sunlight may also affect the leaves of the plant, so if you find this situation, you should move the plant to another location in time and add water to the leaves of the plant by sprinkling water.

Temperature is also a factor that is likely to ensure that the plant is within the right temperature conditions, which is very necessary for the plant to be in such a situation. In the short term, there may not be serious problems, but in the long run, it will definitely have an impact on the growth of the plant.

1.The dry edges of the begonia petals are caused by a variety of reasons.

2.First, if the light is too strong and sunburned by strong light, it should be moved to the astigmatism in time, pay attention to ventilation, and cool down when the temperature is high.

3.Second, due to improper watering, the amount of water is too large to control the water, and the water should be replenished appropriately if there is a shortage of water.

4.The third is low-temperature frostbite, the dry part should be cut off, and the corresponding drug tremor should be sprayed to prevent the invasion of Hui rototch insects.

1. Lack of water Reason: When you find that its leaves are yellow, you need to see if there is a lack of water, and its obvious feature is that the whole plant gradually begins to turn yellow, which is extremely common.

Solution: There are two ways to solve the water shortage, the first is to add water to the pot in time to ensure sufficient water. The second is to sprinkle a little water on the leaves, it won't take long for the leaves to recover, but don't pour cold water when the temperature is high.

2. Stagnant water Reason: Although it likes too humid environment, if it is watered too much, it will produce stagnant water, so that the roots will be soaked in water for a long time, and the roots will rot, and the leaves will begin to turn yellow at this time.

Solution: When the leaves are yellow, you need to remove the yellow leaves first, and then give the flower pine soil, and put it in a ventilated place to ventilate the roots, about 10 days later, the plant will return to normal, but then watering should be careful, absolutely do not let the pot have stagnant water.

Reason: Although it likes the sun, the sun should not be too long, but not too short, otherwise it will cause the leaves to turn yellow.

Solution: When the leaves turn yellow, if it is caused by insufficient light, it needs to be properly exposed to the sun every morning. If it is caused by too much light, then it needs to be moved to a cool place and properly sprinkled with water to replenish the moisture of the plant.

Reason: Although it likes fertilizer, it will basically top dressing every month, otherwise it will be malnourished, and the leaves will begin to turn yellow at this time. However, when fertilizing, the concentration should not be too high, because this will make it overnutrient, the plant will start to grow wildly, and the leaves will start to turn yellow.

This is caused by fertilization.

Solution: First wash the potting soil with water in time, and clean up the excess fertilizer and water, or replace a part of the soil. In order to allow its leaves to return to normal as soon as possible, it is also necessary to properly hydrate it.

Reason: If the yellowing of the leaves is not caused by the above conditions, then it is necessary to see if it is caused by insect pests.

Solution: If the leaves turn yellow due to pests and diseases, you need to take care of it carefully, give it timely medicine, and cut off the part that has been damaged by the disease.

1. Uncomfortable temperature.

Reason: Lige begonia is not resistant to high temperatures, once the temperature exceeds 22 degrees, the growth of Lige begonia will be very slow. If the temperature reaches 30 degrees, the begonia will stop growing and the leaves will turn yellow and white.

Treatment: If the temperature is too high, do some temperature adjustment appropriately, and then reduce the temperature to a temperature suitable for the growth of Lige Begonia as soon as possible, with 18 to 22 degrees as the right grip.

2. Excessive fertilization.

Reason: The demand for fertilizer is not large, if the fertilizer is too much, the root system is difficult to fully absorb the hot substance, resulting in the final appearance of yellow leaves.

Treatment: Fertilization should be stopped first, and then water should be injected into the soil to allow excess fertility to drain out of the bottom of the pot with the water flow. Late fat should not be too much, just an appropriate amount.

3. Causes of pests.

Reason: Lige begonias are also harmful insects, such as red spiders, aphids, etc. When they eat the leaves of the begonias, they destroy the growth of the plant and cause the entire leaves to turn yellow and wither.

Usually it is necessary to strengthen the management of fertilizer and water, enhance the resistance of Lige Begonia, and spray chemical insecticides such as trichlorfon for prevention and control.

When the leaves wither and roll, the first thing you need to see if there is less water is the most common, and its most abundant feature is that the top of the plant gradually withers downward. The measures that need to be taken for such a thing are hydration, and you can choose two methods of watering immediately and sprinkling water on the leaves to hydrate and moisturize, and it is best to carry out the two methods together, so that the Lige Begonia can be repaired quickly. It should be noted that in the conditions of hot weather, it is not necessary to apply water with too low ambient temperature.

In addition to less water, too much watering will also occur leaf rolling, the way to distinguish at this moment is to observe the bonsai soil, if there is water in the pot, it is likely to be too much watering, which is also one of the reasons for the disappearance of the leaves or problems. At this time, the plants should be moved into the room to prevent the sun from shining and the wind blowing gently, and at the same time cut off a part of the leaves, moderately remove a part of the soil layer in the pot, and replace the dry soil layer, usually for a period of about one to two weeks, the plants in the pot will recover.

If there is too much fertilizer in the soil layer, it will cause water to seep into the plants, which is also very serious and may cause the plants to wither, so be vigilant. At this time, it is necessary to clean the bonsai soil with tap water first, and immediately drain the excess water. Or remove a part of the soil layer and replace it with a normal one.

In order to restore the plant more immediately, the leaves should also be filled with water at the same time, and the key part of the plant should be maintained.

If the above conditions are cleared, it is necessary to consider whether there is a disease, if there are no prominent pests and diseases on the leaves, it is necessary to pay attention to the roots of the plant, immediately choose drugs**, and remove the diseased part. Begonias prefer a semi-shaded growing environment, and if they are exposed to too much sunlight, they will obviously cause problems with the leaves of the plant.

At this time, it is necessary to move the plant to another part as soon as possible, and fill the leaves of the plant with water according to the method of sprinkling water. Lige Begonia belongs to the more squeamish, particularly sensitive plants, the maintenance process should pay attention to proper watering, effective fertilizer, it is best to use Lige Begonia special fertilizer, in addition to the blooming need to cut the fallen flowers and dead branches on time, reduce unnecessary nutrient consumption, improve maintenance management. laughs.

It may be caused by poor nutrition, it may be caused by lack of nutrients, it may be caused by a lack of potassium fertilizer, it may be caused by a lack of coronal conduction, or it may be caused by a lack of fertilizer. It is necessary to pay attention to the temperature of maintenance, the way of breeding, the process of Yanhengshan breeding, the overall growth process, and the moisture.

Maybe it's because of bugs. Therefore, you must pay attention to getting more insect repellent at ordinary times. In addition, maintain the right temperature and humidity.

It may be caused by lack of water, or because of improper watering and excessive fertilizer amount, so you must pay attention to water and fertilizer management.
