What s going on with scorched leaves of red leaf begonias trees?

There are many reasons why begonia leaves dry up. If it is because there is too little watering, it needs to be replenished in time; If it is due to lack of light, the plant needs to be moved to a sunny place; If it is caused by poor air circulation, the plant needs to be moved to a ventilated place for maintenance; If it is caused by insufficient fertilization, it is necessary to increase the amount of fertilization appropriately. Next, I will tell you about the reasons and solutions for the drying up of begonia leaves.

1.Too little watering.

Begonias have high requirements for water, and the amount of watering should not be too much or too little. If the vegetation is in a state of water shortage for a long time, it is easy to cause the leaves to dry out, so you need to replenish water in time to keep the soil in a slightly moist state. You can also sprinkle water on the leaves of begonias to delay the evaporation of water from the plants and increase the humidity of the surrounding air.

2.Lack of light.

Begonias prefer to grow in a sunny environment, and lack of light can lead to stunted plant development and dry leaves. The begonia needs to be moved to a sunny place to ensure that it has enough light. Generally, spring, winter and autumn can accept full sun exposure, and the plants can be moved to indoor cultivation according to the situation in rainy weather.

However, in summer, it is necessary to avoid the sun at the right time, and avoid direct sunlight.

3.Insufficient fertilization.

Begonia needs sufficient nutrients to grow, and if the fertilization is insufficient, it is easy to lead to problems such as poor growth of begonias and dry branches and leaves. It is necessary to supplement fertilizer in time, and the principle of "thin fertilizer and more application" should be followed, and too much can not be applied at one time, otherwise it will damage the roots of the plant. In spring and autumn, fertilize 3-4 times a month with phosphorus fertilizer, and begonias will stop growing in summer and winter, and fertilization can be suspended.

Begonias are maintained in this way, grow vigorously, and flowers continue to bloom!

1. Insufficient or too strong lightPlants produce nutrients needed for branch and leaf growth and flower bud differentiation through photosynthesis, and the lack of light will naturally have an effect, and the most direct manifestation of plants is leaf yellowing. If there is a lack of light for a long time, it is difficult to bloom normally. However, the leaves of the begonia are thin, and they cannot be exposed to the sun, otherwise the leaves will also wither, especially at noon in summer, and the potted begonia is particularly easy to be sunburned.

2. Excessive fertilizationBegonia belongs to herbaceous plants, its branches are very fragile, normally speaking, begonias in flowering fertilizer is indispensable, but do not apply thick fertilizer, it is best to apply liquid fertilizer. Applying too much fertilizer can damage roots and branches, and leaves can burn.

3. Overwatering or stagnant waterBegonia likes a moist environment, but the roots can not accumulate water, once the water is excessive, its roots will rot, and the roots can not give the leaves nutrients in time after problems, so the leaves are scorched and dry.

The yellowish and charred leaves of the begonia flowers may be the cause of soil compaction or alkaline, and should be replaced with loose, breathable acidic soil. It may also be the reason for too much fertilization and large fertilizer concentration, proper fertilization to maintain nutrients, too much fertilization needs to be diluted with watering. It can also be the cause of too little or too much watering, maintain the amount of water, and maintain ventilation when there is stagnant water.

Or it may be caused by temperature discomfort, and the temperature should be adjusted.

First, the soil is unsuitable.

Reason: Begonia flowers like to grow in acidic soil, if the soil is not suitable, the comparison of compaction is not permeable, or it is alkaline, it will cause the roots of begonia flowers to be affected, affecting the growth of begonia flowers, resulting in yellow and scorched leaves.

Solution: Provide suitable soil for begonia flowers, and replace it with loose and breathable acidic soil, which is conducive to the normal respiration of the roots.

2. Excessive fertilization.

Reason: Begonia flowers need a certain amount of nutrients to maintain in the growth, but if the amount of fertilizer is too much, the concentration of fertilizer is too large and too concentrated, it will cause the roots of begonia flowers to rot, and the normal function of transporting water and fertilizer will be affected, resulting in yellowing and scorching leaves.

Solution: Proper fertilization can be applied when breeding, reasonable fertilization to ensure good nutrient supply, avoid the use of thick fertilizer, you can properly use Bika water-soluble fertilizer, do not fertilize too much, too much fertilization needs to be watered to dilute.

3. Improper watering.

Reason: Improper watering will also cause the leaves of begonia flowers to turn yellow and curly, if the watering is too little, the begonia flowers require less water, if not watered for a long time, it will cause yellow leaves to burn the leaves, if you water too much, it will also lead to rotten roots, and the leaves will also be scorched.

Solution: Keep watering well, but avoid stagnant water, if there is stagnant water, keep ventilation to promote evaporation.

Fourth, the temperature is uncomfortable.

Cause: High or low temperatures can cause yellow leaves to scorch.

Solution: Ventilation is required for high temperature in summer, and warmth should be kept warm in winter.

Cause of wilting: If the begonia flower is placed outdoors in the rainy season and it is drenched in a lot of rain and it is not drained in time, or too much water is watered for it in the process of maintenance, it is easy to damage the root system of the plant, so that its efficiency of absorbing nutrients is reduced, and the leaves are yellowed and wilted.

Solution: First of all, you need to change the soil for the plant, if the situation it is lightly waterlogged, you can drain the stagnant water, replace it with half of the dry soil, if it is more waterlogged, you need to replace most of the soil. After changing the soil, pay attention to rain protection and control watering, so that it cannot be waterlogged again.

Yancheng: China Begonia Garden covers an area of 2,500 acres, and is the largest begonia theme park in the country, with the most complete varieties, many functions and rich connotations. At the same time, Begonia Garden cooperates with well-known domestic begonia research institutions to carry out the production of new varieties of begonia and the research and development of value-added technology.

More than 120 varieties and nearly 150,000 begonia trees have been planted in the park. The world's begonias look at China, and China's begonias look at Yancheng. Enrich the structure of begonia varieties and promote the culture of Chinese begonia.

1. Illumination. 1.Plants receive too much sunlight for too long. At this time, it will affect the production of chlorophyll, so the leaves will become thinner and redder. 2.Usually, you can put the middle of the plant socks in a cool place and recover for about a month.

2. Temperature. 1.If the temperature of the breeding environment is too low or the ambient temperature difference is too large, the growth of the plant will be stagnant, and red leaves will appear. 2.At this time, it is necessary to place the plant in a constant temperature environment with a high temperature. After a few weeks, the plants can return to normal.

3. Growth and development.

If the environment in which the plant is located is suitable for its growth, whether it is temperature or humidity, the plant does not suffer from insect infestation, it may be due to the normal growth and development of the plant, which causes the metabolism to cause the leaves to turn red. It's usually fine after a while.

Fourth, moisture. 1.If the plant is severely dehydrated, the leaves of the plant may turn red. 2.At this time, it is necessary to replenish the water of the plant in time and loosen the soil of the plant appropriately.

1.Variety problem: Begonia leaf red is a very common problem.

There are many varieties of begonias, and there are many colors, and some varieties have red leaves when they have just grown or are still relatively tender. It's a matter of variety. If the leaves of the begonia are very thick and grow vigorously, but the leaves are red, don't mind that this is normal.

Generally, reddish begonia leaves are heavier, but when the temperature difference is large, it will grow and bloom normally. 2.The leaves withered.

The leaves of begonias will turn purple, but the leaves of begonias are mostly green. It is interesting to take a closer look at the leaves of begonias. Of course, there is another cause of red leaves, which is that the leaves are wilted and dried, and the leaves are red.

This is not normal. It may be that the light is too strong for it, or it is dehydrated or the roots are rotten, resulting in less nutrients being absorbed. This must be a short-eyed flower that usually keeps it in a sunny place for 46 hours a day.

If the sunlight is too strong, its roots will absorb nutrients weakly, and it is easy to wilt and turn the leaves red. Begonia roots are weak, so don't water them too much. Wait until the upper surface of the pot has dried for about two or three centimeters before watering.

If there is not enough water for a long time, it is easy to cause the leaves to lose water, wilt and turn red. 3.If there is a problem with the root system, if the root system of the begonia cannot absorb nutrients, the leaves will slowly turn red.

It is necessary to see if there is a problem with the root system, and cut off the rotten roots in time. Lighter ones may slow down. If the rotten roots are serious, only pretend to be God, and then cut them down.

There is also a problem of wilting red leaves of begonias, that is, frostbite. If the temperature persists around freezing, the begonias will get frostbite overnight and the leaves will wilt. If the frostbite is too severe, the begonia only has a few red leaves.
