Why are the leaves of the Chinese rose wrinkled?
The web will tell you about the small green plant maintenance experience of the Chinese rose leaves that are wrinkled, and then share the detailed content.
Recently, there has been plenty of rain, and many flower friends have found that their Chinese roses have started to grow疯狂ly, especially the climbing Chinese roses, which are even more robust, with a new branch growing more than one meter high.
However, recently, flower friends have encountered such a problem: although the climbing Chinese roses are growing strongly, all the leaves are wrinkled and not at all unfolded. Why is that?
From the above photo of the soil, it can be clearly seen that the new leaves of this Chinese rose are all wrinkled and not as unfolded as normal Chinese rose leaves. Have you encountered the same situation?
Why are the leaves of the Chinese rose wrinkled?
If the leaves of the Chinese rose show a wrinkled phenomenon, first, we need to observe the growth of the Chinese rose and the characteristics of its leaves.
If the Chinese rose is growing especially vigorous, there is no need to worry too much, as it should not be a big problem. Then, we should carefully observe the leaves of the Chinese rose.
Why are the leaves of the Chinese rose wrinkled?
Turn over the wrinkled leaves of the Chinese rose and observe the back. If there is no white powder, we can rule out powdery mildew. Generally, Chinese roses infected with powdery mildew have wrinkled leaf edges and do not show unevenness in the middle of the leaves.
After ruling out powdery mildew, we need to rule out the possibility of pest damage. Thrips can cause significant harm to Chinese roses in summer. When leaves appear deformed and wrinkled, special attention should be paid to whether it is the damage caused by thrips.
The most typical manifestation of Chinese roses affected by thrips is that the small leaves at the tender tips of the branches will turn black and deformed, and the larger leaves will also show deformities and scars.
From the picture, we can clearly see that the leaves of this Chinese rose have no scars, the terminal buds are not black, and the leaves are large, with thick branches.
Then, why do the leaves become wrinkled?
Actually, this is a manifestation of fertilizer damage! It is caused by too much fertilizer, leading to poor metabolism of the Chinese rose and resulting in wrinkled leaves.
This type of fertilizer damage does not have much impact on the growth of the Chinese rose. The cause of such fertilizer damage is mostly due to the excessive use of long-acting fertilizers. With the temperature rising, the release rate of fertilizer efficacy accelerates, causing the Chinese rose to experience mild fertilizer damage due to poor metabolism.
When this phenomenon occurs, there is generally no need for special treatment. As the Chinese rose grows, the fertilizer damage will gradually disappear on its own. In the process of maintaining Chinese roses, we will inevitably encounter some problems. When encountering problems, you can refer to the book "How to grow Chinese roses from scratch" written by Green Plant Enthusiast Network, which has a chapter on common problems. Green Plant Enthusiast Network has summarized many common problems of Chinese roses and corresponding solutions.
