What should I do if the leaves of bamboo begonias fade and turn white?

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.

Begonia flowers. White spots on the leaves are due to infection with scale insects.

It can seriously harm growth. Therefore, it is necessary to treat it with medication at the early stage of discovery. The scale can be sprayed, the liquid is absorbed by the plant, and the scale insect will absorb the poisonous juice and die. When spraying, the temperature should be high, and the temperature should be between 28-32 degrees, and the temperature should be in a high temperature environment.

The liquid is transmitted faster and is more likely to be poisoned. In addition, it is also necessary to pay attention to timely temperature control and ventilation to avoid reinfection.

Key points of maintenance of bamboo begonia: bamboo begonia likes warmth, suitable growth temperature at 19 24 degrees, not cold-tolerant, winter temperature below 10 degrees leaves are easy to freeze, but the root system is more cold-resistant. Plants don't like bright light and prefer to grow in low light.

It prefers neutral or slightly acidic soils that are loose, breathable and have good drainage performance.

1. What should I do if there are white spots on the leaves of begonia flowers.

Most of the white spots on the leaves of begonia flowers are infected with scale insects, and they should be treated as soon as possible in the early stage of discovery. It can be sprayed with scales, and 750-1000 times of liquid can be selected. The liquid medicine is absorbed by the plant, and the scale insects will absorb the poisonous sap and will die, which has a good effect.

Pay attention to the high temperature environment when spraying, and the temperature should be between 28-32 degrees. Because the higher the temperature, the faster the liquid is conducted, and the more likely it is for pests to be poisoned. When spraying, spray twice in a row, with an interval of 5-7 days.

2. The reason why there are white spots on the leaves of begonia flowers.

1. The temperature is too high: Begonia flowers are mostly infected with scale insects in summer. The temperature in summer is too high, and the insects multiply faster in the hot environment. Therefore, it is recommended to properly cool down when the temperature is high to avoid infection. <>

2. Poor ventilation: If the environment is poorly ventilated, it is easy to be infected with scale insects, especially for indoor maintenance. It is necessary to ventilate more and prune in time to avoid insect pests.

3. Strong floral fragrance: The fragrance of begonia flowers is relatively strong, which is easy to attract scale insects. This situation is difficult to control, usually pay attention to more observation, find pests and timely use of drugs to avoid aggravation of pests.

The main causes of leaf litter are: * Low temperature or extreme heat. Begonia likes warmth, the most suitable temperature for growth is 15 18, although it is a more cold-tolerant species in begonia, but when it is below 5, the leaves are also susceptible to freezing and falling off.

The bamboo begonia is afraid of the heat, the temperature reaches more than 30, and the plant grows slowly.

Bamboo begonia is a flower that is very suitable for maintenance at home, so what should we do if there is a rotten root when we maintain bamboo begonia? Let's take a look at it today. Solution to rotten roots of bamboo begonia:

Pruning rotten root bamboo begonias are very afraid of standing water, if the maintenance period is too frequent watering to cause water accumulation, then the bamboo begonias will have rotten roots.

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.

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.

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.

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.

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.
