What causes the curling and drying of rose leaves?
When caring for roses, we may encounter a situation where the leaves curl and dry. What causes this? Let's find out below.
Reasons for the curling and drying of rose leaves: Pest Infestation
Roses are very prone to pest infestation in summer and autumn because the temperature is high and there is more rainfall, making the air humid. Without a good ventilation environment, roses can suffer from pests, causing the leaves to curl. At this time, we need to spray pesticides promptly and maintain good ventilation to reduce the chance of pest infestation.
Disease
When roses have leaves that curl, it is likely due to powdery mildew. If we find that the leaves of the rose are not only curling but also have white powder on the back of the leaves, then the rose definitely has powdery mildew. At this time, we can use diluted alcohol (200 times) to wipe the leaves, and then spray the remaining alcohol onto the leaves. After a while, the leaves of the rose will recover.
Fertilizer Burn
Roses are fond of fertilizer and require regular fertilization to ensure normal growth and flowering. However, we should not over-fertilize. If excessive fertilization occurs, the roots of the rose will be damaged, preventing the rose from providing water to the leaves, which can cause the leaves to curl. When over-fertilization happens, we should immediately flush the soil with water to dilute the fertilizer in the soil.
The above introduction to the specific reasons for the curling and drying of rose leaves is hoped to bring some floral knowledge to flower enthusiasts.
