What are the consequences of frequent rain exposure on Chinese roses?
In the summer rainy season, it is common to encounter this situation when cultivating Chinese roses. After each rain, we notice that the branches of the roses collapse extensively, and the flower buds droop. Is this phenomenon normal? Today, I will tell you about the manifestations of Chinese roses after being exposed to rain.
1. The bottom old leaves will fall off
The initial symptom is the appearance of black spots, which are small dots. Gradually, the leaves turn yellow and within a few days, all the bottom leaves fall off, leaving only bare branches. This is the first symptom.
2. The flower buds will mildew
Both open and unopened flower buds may show signs of mildew, rotting, and decay. This is a result of excessive rain, causing water accumulation in the flower buds. This phenomenon can easily allow pathogens to enter the plant, leading to branch contraction and withering, eventually causing the plant to die, which is a sign of infection.
In such cases, it is recommended to use pyraclostrobin immediately, dilute it with water, and spray it on the roots to kill the pathogens inside the plant and prevent further spread. Otherwise, the entire plant may not be saved, so it is important to use fungicides promptly.
3. This will lead to an increased load-bearing capacity of the Chinese rose
Soft branches, such as those of the flower stems, will collapse due to excessive rain. If these branches are already weak, they are easily prone to collapse and water accumulation in the flower buds, which increases the load. This can easily cause the branches to break, having an adverse effect on the overall growth of the plant.
Therefore, during the rainy season, it is necessary to protect Chinese roses from rain. It is not recommended to expose them to rain for consecutive days, as this can cause root rot and infection with pathogens.
The above [] provides a specific introduction to the consequences of frequent rain exposure on Chinese roses. I hope you will like it!
