What causes the stems of bamboo begonias to turn brown?

In general, there may be four reasons for the yellow leaves of bamboo begonias. If the light is too strong, you need to move to a cool place with scattered light; If it is because of soil problems, it needs to be replaced with fertile and soft soil in time; If it is due to too much water, it should be depotted and drained, pruned off the rotten root system and replanted; If it is because of insufficient nutrients, it is necessary to supplement fertilizer in time and replenish nutrients.

Causes and treatment methods of yellow leaves of bamboo begonias.

1.The light is too strong.

Reason: Begonias love shade and should not be kept in an environment where the sun is too strong. If exposed to strong direct light, it is easy to cause slow growth and yellowing of leaves.

Measures: It needs to be moved to a shady area with scattered light in time, but when the sun is too strong outside at noon, a blackout net can be used to avoid bright light.

2.Soil problems.

Reason: Begonia is suitable for growing in thick, fertile soft soil, and the nutrients in the soil must be sufficient. If it is maintained with strong clay soil, it will hinder growth, and the leaves will become smaller and yellower.

Measures: Replace the soil with soft and fertile soil, mix humus soil, and apply a small amount of basal fertilizer to increase the nutrients in the soil, which can promote its recovery and growth.

3.Too much moisture.

Reason: Bamboo begonias are more afraid of waterlogging. If you water too much and cause too much water, it is easy for water to accumulate in the potting soil. This causes the roots to rot and the leaves to turn yellow.

Measures: If there is stagnant water in the potting soil, it is necessary to depot it in time, cut off the rotten root system, and replant. Pay attention to the amount of water when watering daily, and let the potting soil moisten.

4.Nutrient insufficiency.

Reason: Begonias like fertilizer more, especially during the growing period, they need more fertilizer. If the nutrients are insufficient due to insufficient fertilization, it will not be able to meet its growth needs, and the growth will be slow, and the problem of yellow leaves will slowly appear.

Measures: If the fertilizer is not enough, it is necessary to supplement the fertilizer in time, and apply liquid fertilizer two or three times a month to facilitate absorption. In addition, some basal fertilizer can also be applied to the flower soil.

Bamboo leaf begonia is a special variety of begonia flowers, its stem nodes are thick, the leaves are green, the flowers are very beautiful, loved by many flower friends, and it is very suitable for ornamental plants to maintain at home. However, when maintaining bamboo begonia flowers, there will be leaf fading, what is the reason for this, and what should be paid attention to in winter maintenance?

The reason for the fading of the leaves of the bamboo begonia flowers.

Begonia flowers like moist environments, but if they are watered too much, the roots of the plant will rot due to water accumulation, so the leaves will change color and turn white or fall off. Therefore, it is necessary to prevent water accumulation and excessive watering when watering, and it is best to choose acidic soil with good drainage and loose and breathable potting soil, so as to weaken the impact of water accumulation on plants.

Begonia flowers like warmth, the temperature suitable for growth is 15-18 degrees Celsius, but if the temperature is lower than 5 degrees Celsius, the leaves of bamboo begonia flowers will turn white and fall off due to frost. Therefore, before winter, it is necessary to move indoors in time to ensure indoor temperature, pay attention to cold and warmth, and prevent plants from being damaged by frost.

During the growth period of bamboo begonia flowers, it is necessary to apply sufficient fertilizer to the plant, but if it is applied too much, it will burn the root system of the plant, causing the leaves to fade and fall. Therefore, it is necessary to control the amount of fertilizer when fertilizing, and also make sure that the root system is not touched during fertilization, so that the plant will not have leaf fading.

The temperature is high in summer, the light is strong, if there is no shading, it will be very easy to cause the leaves of the bamboo begonia flowers to fade or change color, and the temperature and light in other seasons are very suitable, and the phenomenon of fading will not occur because the light is too strong, but it will cause the plant to grow in vain because of insufficient light, which will lead to a decrease in the number of flowers and leaves of the plant, and the leaves of the plant will also fade in serious cases.

What to pay attention to in winter maintenance.

Pay attention to pruning: Bamboo begonia flowers are plants that grow all year round, and they must be pruned in time when maintaining, so that the plants will grow more robust. If the bamboo begonia flowers grow too tall, it will be difficult for the nutrients of the plant to keep up, and there will be leaf dropping, so in the growing season of the plant, the diseased branches, weak branches and lush branches of the plant should be pruned off.

In the winter maintenance of bamboo begonia flowers should pay attention to watering, temperature, light and fertilization, in winter to reduce the number of watering, the temperature can not be lower than 5 degrees Celsius, fertilization should be thin, but also to give sufficient light, otherwise the bamboo begonia flowers will fall leaves, poor growth, so in the winter maintenance of bamboo begonia flowers must be careful, so that the plant will be more ornamental.

Frequent ventilation: move the plants indoors before winter, and when maintaining the bamboo begonia indoors, be sure to move the bamboo begonia flowers to a ventilated place for ventilation, if the indoor air is not circulated, it will lead to various pests and diseases of the bamboo begonia, affecting the normal growth of the plant.

What is the reason for the net browning of bamboo begonias? It's possible that this one has melanoma.

1. Pruning and disinfection.

After the branches of begonia flowers are found to be rotten, they need to be pruned in time to remove the rotten branches and avoid the continued spread of germs. After the branches of begonia flowers are treated, potassium permanganate solution should be sprayed into the incision to disinfect and sterilize, which can remove bacteria and promote the healthy growth of begonia flowers.

2. Prevention and control of diseases.

The branches of begonia flowers are rotten, and it is necessary to determine whether it is the cause of the disease. After determining that it is a disease, it is necessary to cut off the infected branches and leaves, remove them, use carbendazim solution to disinfect and sterilize them, and spray them continuously until the disease is eliminated.

3. Deal with rotten roots.

The rot of the branches of the begonia flowers is most likely caused by the rot of the roots. If the begonia flowers are watered too much, or if they are fertilized too much, and too concentrated fertilizer is applied, it will cause a burden on the roots, cause root rot, and then spread and cause branch rot. You can gently take the begonia flower plant out of the soil, use scissors to remove the rotten roots and prune them off, and after treatment, you can prepare new soil and re-pot it.

Begonia. Fourth, see the light appropriately.

If the begonia flower grows in a dark environment, it will also lead to the aggravation of branch rot, you should give the begonia flower enough light, avoid growing in the shade for a long time, keep good light, and can also alleviate the rot of the branches.

The following two aspects cause the leaves of the bamboo begonia to turn white, the first is that the bamboo begonia can not be exposed to the sun for a long time in summer, and it needs to be properly covered and maintain a certain humidity. Secondly, it is likely to be caused by pests and diseases, such as leaf blight, powdery mildew, etc., if it is caused by pests and diseases, it is recommended to use the fungicide Desen zinc diluted with water to spray the leaves or irrigate the roots.

It may be that the watering is insufficient, or the soil is waterlogged, check the soil moisture adjustment, put it in a low-light, ventilated place, reduce fertilization, and it will relieve the whitish after a few days.

If you have mold, you should remove the leaves with white spots, pay attention to ventilation, and go to the flower shop to buy a sterilizing potion to spray.

This could be one of the following reasons.

1. It is generally caused by iron deficiency, and ferrous sulfate or foliar spray is applied locally.

2. Leaf mite harm.

3. Caused by not seeing sunlight.
