Dragon bone flower is a common flower plant, but familiar pot friends love and hate it. Love is mainly love it domineering and unique, hate is mainly hate it covered with thorns, the body also contains toxins. However, as a pot friend who likes to plant it in potted plants, love is naturally better than hate.

Dragon bone flower also has a great advantage, that is, strong adaptability to the environment, conservation management does not need to worry too much, even if it is rough culture, but also can raise it. Although maintenance management is simple, but sometimes we still find that the leaves of keel flower appear yellow phenomenon. So, what's with the yellowing of the keel leaves?

When encountering the phenomenon of yellowing leaves of keel flowers, we do not have to panic, this is just a small problem that may occur in the process of conservation and management and cause a little bad growth phenomenon. As long as we can find out the reasons and deal with them in time, we will soon return to normal, mainly in the following aspects:

1. Too much light

Although keel flowers like light, but also need to avoid long-term direct light, especially in the summer sun environment, must take shade measures, otherwise it is easy to appear yellow leaves phenomenon.

When this happens, we should immediately take shade measures for it, or move the flowerpot directly indoors near the balcony, or where it can receive scattered light.

2. Too much watering

Many plants will cause excessive watering in the basin water and let the plant appear rotten root phenomenon, if the keel flower due to excessive watering caused by long-term basin water, the same will occur rotten root phenomenon, rotten root after the most direct performance is yellow leaves.

For the phenomenon of yellow leaves caused by excessive watering, first of all, we should immediately stop watering, drain the excess water in the basin, and open the basin soil to dry excess water. Of course, it would be best if they could cut off the rotting parts of the root system. It should be noted that keel flowers are more drought-tolerant than wet-tolerant, and it is better to let them dry than to let them drown. In winter, even if it is only watered once, the keel flower will not be dried to death.

3. Excessive fertilization

Keels like loose, fertile soil, but that doesn't mean they can fertilize heavily. If the original fertilization is too much, or the concentration is too high, it is easy to cause fertilizer damage phenomenon, the same will burn the roots of the plant, and then the phenomenon of yellowing leaves.

If fertilization is too much, it should be watered once in time to dilute and remove fertilizer. At the same time, it is also a good method to pay attention to the soybean or peanut soaked and buried in the pot soil when fertilizing the keel flower, or to irrigate with soybean soaked in water.

4. Normal defoliation

If yellow leaves are found during the defoliation period, especially the older leaves below, then yellow leaves in this case are a natural occurrence in the normal metabolic process. You can ignore too much, but it is recommended to cut off the dried yellow leaves and clean up the yellow leaves falling from the basin to avoid breeding germs.

5. Caused by pests and diseases

In addition to the above reasons, the invasion of pests and diseases is also an important reason for the yellowing of leaves in keel flowers. Therefore, we should observe carefully at ordinary times. Once we find that the leaves are infected with pests, or when the plants are yellow due to illness, the young pests will be killed, and no pests will be sterilized. Carbendazim can be used according to a certain proportion of water, stir well after pouring in the roots of dragon flower can be.
