Do you know the reason for the yellow leaves of the Chinese rose?
For most women, here is an introduction to the green plants and flowers related to the reason for the yellow leaves of the Chinese rose, the specific introduction is as follows:
Previously, some flower friends asked, "How to distinguish whether the yellowing of Chinese roses is caused by excessive fertilizer or water?" Today, let's talk about several common yellowing conditions of Chinese roses and the characteristics of various yellow leaves.
Common reasons and characteristics for yellow leaves of Chinese roses
The common situations of yellow leaves in Chinese roses can be summarized into about 7 conditions.
1. Fertilizer damage yellow leaves
From the perspective of personal care, yellowing caused by improper fertilization is quite common, which is what we commonly call fertilizer damage.
The main characteristic is that the yellowing of leaves occurs quite suddenly and develops rapidly, usually first appearing on the edges and tips of the leaves, and then gradually spreading to the center of the leaves.
The degree of yellowing is influenced by the concentration of the fertilizer; the higher the concentration, the larger the area of yellowing, and the faster the yellowing speed. The development of yellowing is also influenced by the duration of the fertilizer effect; the longer the fertilizer effect lasts, the more serious the fertilizer damage, such as the damage caused by slow-release fertilizer.
Do you know the reason for the yellow leaves of the Chinese rose?
Fertilizer damage yellowing is irreversible and usually occurs 2-5 days after fertilization. The higher the concentration, the earlier it occurs. The initial symptom is often the dehydration and withering of the leaf tips, which then develop into yellowing and drying. If a large amount of water is poured around the roots in time, the fertilizer damage can be mitigated, and the yellowing will stop developing.
2. Chemical damage yellow leaves
In the process of management, if the concentration of pesticides is too high, it can cause chemical burns, known as chemical damage.
Chemical damage can sometimes be very similar to fertilizer damage, but it often occurs on young leaves, while older leaves show fewer symptoms. Abnormal growth, chlorosis, or even blackening of the leaf tips and edges are all signs of chemical damage.
Sometimes chemical damage can also cause scattered yellow spots on the leaf surface, which is caused by uneven pesticide spraying leading to localized burns. There is often no good way to mitigate chemical damage, and it can only be regulated by the rose's own growth. We can use a little fertilizer to promote the recovery of the Chinese rose.
