However, if too many leaves turn yellow, measures need to be taken.
Here are several common treatment methods:

In autumn, you can trim the top of the rose branches appropriately to reduce the plant's burden and allow it to enter the dormant period better. At the same time, remove withered and yellow leaves and flowers to prevent the breeding of diseases and pests.
2. Fertilizing
In autumn, you can fertilize the roses appropriately to increase the supply of nutrients to the plant, improving the plant's disease resistance and cold resistance. It is recommended to use compound fertilizers containing potassium, phosphorus, nitrogen, and other elements.
3. Watering
In autumn, the amount of watering for roses should be reduced appropriately but should not let the soil become too dry. It is recommended to water once a week to keep the soil moist.
4. Preventing Diseases and Pests
In autumn, roses are prone to attacks from various diseases and pests, such as aphids, powdery mildew, and black spot disease. It is recommended to spray insecticides and fungicides regularly to prevent the breeding of diseases and pests.
