The four Seasons Begonia is so vibrant and full of flowers.

Four Seasons Begonia is a kind of ornamental plant suitable for family culture, also known as Begonia. Its florescence basically covers the whole year, and flowers bloom all the year round when properly cultivated. The four seasons crabapple is resistant to yin and yang, likes warm and afraid of cold, and grows best in a slightly humid environment.

The cultivation of begonia in four seasons is not a difficult task for some veterans who have experience in flower conservation, but it may not be so simple for some flower lovers who have just come into contact with flower culture. Today, Hua'ergu will introduce to you the reason why the leaves of four Seasons Begonia are yellowing and how to deal with them.

The common causes of yellowing of Begonia leaves are as follows: overwatering, underwatering, excessive light, insufficient light, too high temperature, too low temperature, insufficient nutrients, excessive fertilization, environmental mutation, rotten roots, diseases and insect pests and so on. Below we briefly introduce and introduce the treatment method!

1. Overwatering

Too much watering will cause the roots of Begonia to be in a state of stagnant water, which can easily lead to anoxia and inhibition of nutrient transport in branches and leaves, and then the leaves will turn yellow. if the stagnant water for a long time, in a serious state, it is easy to cause its roots to rot.

Therefore, too much watering is very undesirable, we generally need to wait for the surface of the basin soil to dry before the next watering, so as to avoid the problem of overwatering as much as possible.

2. Insufficient watering

Four Seasons Begonia likes to grow in a slightly humid environment, which is a drought-intolerant plant. Once there is a long-term lack of water, the leaves will not be able to get enough water to turn yellow.

Therefore, we not only need to pay attention to not watering more, but also can not be watered for a long time. If we water according to the principle of seeing dry and wet, there will generally be no moisture problem, which will cause the leaves of the four seasons begonia to turn yellow.

3. Excessive illumination

The four seasons crabapple likes the sun, but it can not grow well in the strong light for a long time. For example, the hot sun exposure in summer can easily cause the leaves of the four seasons crabapple to burn and turn yellow, and the rapid evaporation of water under high temperature and strong light will also lead to insufficient supply and demand and yellowing.

Therefore, under the premise of ensuring sufficient light, we should avoid excessive sunlight, especially in summer when we need semi-shade maintenance, which is conducive to the good growth of begonia.

4. Lack of light

Four seasons crabapple likes yang and tolerates yin, but long-term cultivation in shady places will lead to lack of light and yellowing or yellowing of leaves, which is a symptom of lack of light caused by insufficient photosynthesis.

Therefore, we need to make sufficient scattered light to meet the growth of begonia, avoid breeding it in too dark corners, or regularly put it in a place with sufficient light for maintenance for a period of time.

5. the temperature is too high

Too high temperature can easily inhibit the water transport of Begonia, which will cause the problem of leaf yellowing, especially in summer, we need to keep it in a cool place to avoid the problem of leaf yellowing.

Therefore, when the summer temperature is relatively high, we need to transfer it to a cool place for maintenance in time to prevent the high temperature from yellowing the leaves.

6. The temperature is too low

Begonia is not tolerant to cold and may cause yellowing of its leaves when the winter temperature is lower than 5 ℃.

Therefore, we need to put it indoors or take measures to prevent cold and keep warm when we breed Begonia in winter to avoid freezing injury.

7. Lack of nutrients

After growing for a period of time, the nutrients of the potted soil will be slowly lost, resulting in a lack of nutrients in the plant. Poor soil will cause the four seasons crabapple to grow thin and yellow leaves.

Therefore, we need to change the pot and soil regularly or fertilize regularly, and if necessary, we can add some fertilizer solution, ferrous sulfate and so on to promote the growth of the plant.

8. Excessive fertilization

The yellowing of begonia leaves caused by excessive fertilization is mostly due to fertilizer damage caused by root burning caused by excessive fertilization, or it may be the wrong use of some inappropriate fertilizers.

Therefore, when we apply fertilizer, we need to apply fertilizer in accordance with the instructions or according to the principle of frequent application of thin fertilizer, which can avoid the occurrence of fertilizer damage to the maximum extent.

9. Environmental mutation

The newly bought four Seasons Begonia will cause the leaves to turn yellow because the environment in which we raise them is very different from that in which the flowers grew before.

At this time, we only need to do a good job of watering dry and wet and avoid strong light, to prevent the occurrence of high and low temperatures can help it to restore growth.

10. rotten roots and diseases and insect pests

Some diseases and rotting root problems will cause the leaves of four seasons begonia to turn yellow, and some rotting roots and other problems are generally caused by improper watering.

Therefore, as long as we control watering, when there are some disease problems, we can save them from water and fire by timely prevention and treatment.

The above are the common reasons and treatment methods for the yellowing of the leaves of the four seasons begonia introduced to you by Hua'ergu. If you also like growing flowers, pay attention to Hua'ergu.
