Second, the reasons for the yellowing of the leaves of flamingos (with solutions)

1. The soil is too alkaline.

In northern China, most of the soil is alkaline, in which the nutrients are relatively scarce, the structure is relatively simple, and it is easy to harden, resulting in a weakening of its ability to absorb nutrients, which will also lead to the yellowing of flamingos leaves.

Solution: if it is a soil problem, we can occasionally trade diluted vinegar or lemonade during conservation to change the acidity and basicity of the soil, and the yellowing of leaves will slowly recover after the soil turns sour.

two。 Apply too much fertilizer or too much fertilizer

In the process of breeding fire crane flowers, if we do not apply fertilizer or apply thick fertilizer for a long time, it is one of the reasons why the leaves of the flower turn yellow. If we do not apply fertilizer for a long time, it will dry up and turn yellow due to lack of nutrients, while applying thick fertilizer will easily burn the plant.

Solution: in the process of its growth, it is very important to let it grow at a comfortable ambient temperature. The suitable ambient temperature for its growth is 22 ℃-28 ℃. We can properly control the temperature when we breed it.

Crane flower is a kind of half-shade plant, it is afraid of direct sunlight, if it is placed in the direct sunlight in the process of breeding, it is easy to appear flamingos leaves yellowing.

Solution: in the process of breeding fire crane flowers, it is best to put them in the place of sunlight scattering, when the summer light is too strong, we also need shade, it is best to move it to indoor semi-shade breeding, so as not to sunburn the plant.

5. Diseases and insect pests infestation

In the process of the growth of the fire crane flower, if we do not maintain properly, it is easy to appear some bad phenomena such as diseases and insect pests, which do great harm to the plant, not only affect its ornamental, but also cause the leaves of the fire crane flower to turn yellow and dry.

Solution: when there are diseases and insect pests and other problems, we must deal with them in a timely manner. If the time is prolonged, the damage to the plant will be great, and it will be troublesome to deal with it.
