What's wrong with the rose leaves curling inward?
Main content introduction: This is a brief experience in plant cultivation regarding why rose leaves curl inward, with a detailed introduction below.
Recently, many flower enthusiasts have been asking about the curling of rose leaves. Let's talk about the possible reasons for the curling of rose leaves today.
Reasons for Rose Leaf Curling
Simply summarized into the following 5 reasons:
1. Young leaves curling
It is very common for young leaves to curl in spring. Many flower enthusiasts worry, is there something wrong with the roses?
Actually, this is not a problem. It's just a way for roses to self-regulate and adapt to the environment, a natural phenomenon that doesn't require our intervention. Just manage and care for them normally.
2. Over-fertilization
Abnormal curling of new small leaves is a common phenomenon in spring, often occurring after fertilization. This is actually a manifestation of fertilizer damage.
Roses grow rapidly in spring, and many flower enthusiasts increase the amount of fertilizer. However, if the amount of fertilizer exceeds the normal metabolism of the rose, it is easy to cause new leaves to curl abnormally, which is actually a manifestation of fertilizer damage, which you can simply understand as the rose having indigestion.
In this case, it is recommended to stop fertilizing first. Generally, the new leaves will become smooth again after about a week of stopping fertilization.
3. High drug concentration
Preventing diseases and pests in roses in spring is also very important. Flower enthusiasts often spray pesticides to prevent diseases and pests, but the proportion of each pesticide is relatively precise. If you don't read the instructions and just pour randomly, it is easy to cause an overdose, leading to the phenomenon of leaf curling due to pesticide damage.
When roses suffer pesticide damage, you can use Jiehaieling to mitigate it. However, if you feel that the concentration of the pesticide you mixed is too high after spraying, you should still spray clean water after 2 hours. Of course, the best practice is to follow the mixing instructions and prepare the correct concentration of the pesticide solution.
4. Disease infection
Rose leaves may also curl when infected with powdery mildew. Be especially careful to observe the new leaves of roses in spring. If they appear twisted, pay attention to the back of the leaves to see if there is white powder. If powdery mildew occurs, treat it promptly.
You can use zinc omethoate, myclobutanil, or kresoxim-methyl to spray, and on the balcony, you can also use 75% alcohol diluted 200 times to wipe the leaves, adding a full spray to the plant for treatment.
5. Lack of trace elements
Sometimes, when roses lack trace elements, new leaves may curl and not stretch out properly, or even become completely deformed, with leaves becoming narrow and small. This situation is often caused by excessive soil alkalization leading to absorption problems in the rose roots.
Therefore, it is important to avoid using fertilizers that are too alkaline and to control the amount when using them. Never think that using a large amount of wood ash as a natural potassium fertilizer is fine, as the alkalinity of wood ash can also have a significant impact on roses.
About rose leaf curling, these 5 points are simply summarized, hoping they are helpful to you.
