1、 Cause of yellowing

1. Improper watering

As mentioned at the beginning of the article, it has rained every day in the past week, and this flower friend has also moved out his flowers, so the flowerpot will be in a state of ponding for a long time, and the roots of the flowers are likely to be retted

2. Alkaline nutrients

It likes a little sour soil. If it is often watered with water containing alkali substances or the soil for planting flowers also has alkali flowers, the leaves will naturally be hurt

3. There has been no change of flowerpot or soil for a long time

The friend flower at the beginning of the article has only been bought for a month, which should not belong to this situation. However, if your family has bought flowers for a long time, has not changed the flowerpot and soil, and the leaves turn yellow, it is likely to be caused by this situation. In this way, the nutrition of the planted flowers can not keep up, and there are not many nutrients for the roots to absorb, so the leaves will lack nutrients

4. Improper light and temperature

When the temperature is higher than 30 degrees Celsius, the leaves will easily dry and turn yellow. If the light is not enough, the leaves cannot breathe and photosynthesis, and will turn yellow

The above reasons sometimes occur alone and often occur at the same time. We should analyze the reason according to the specific situation of leaves

2、 Solution

1. If it is inappropriate to add water, you can move the basin to a cool area, do not add fertilizer, and carefully control the watering. If the basin is not dry, do not spray water. Be diligent in loosening the soil and letting the roots breathe

2. It is more likely that this kind of material will turn yellow during the flower and leaf growth period. You can add 0.2% alum fertilizer water, and the leaves will turn green soon. If it turns yellow during normal growth, it may be that the roots are rotten after watering too much

3. The temperature suitable for the growth of this kind of flower is 13 to 25 degrees Celsius. It takes 6 to 8 hours of sunshine every day. Loving light is its characteristic. No matter where it is placed in the room, it should be guaranteed that the sun can shine, so that it can grow well

4. If you want to trim the leaves after they turn yellow, you should also wait until they recover. At present, you only need to clean the yellow leaves at the bottom, and don't cut them to hurt the roots
