Roses are ornamental plants with high aesthetic value. From April to September every year, they display a variety of shapes and vibrant colors, accompanied by a strong fragrance. Due to their vitality, roses do not require intensive care during regular cultivation. However, many problems can arise, such as why roses shed leaves in winter and what to do if the leaves turn yellow. Let's look at the solutions for rose leaf shedding in winter.
【One, Normal Leaf Shedding of Roses in Winter】

Every living thing needs to undergo metabolism, and roses change their appearance by shedding old leaves. In winter, roses enter a dormant period, and leaves fall off, making way for new leaves to grow in the spring. This helps accumulate nutrients for the next blooming season.

Therefore, there is no need to worry too much about the normal shedding of old leaves. If leaves do not fall off, it might not be a good sign. If roses do not shed leaves in winter, the new leaves that grow in the spring will be few, and the blooming effect will be much poorer.

It is known that roses shed leaves in the northern winter, which is normal. However, due to climate differences, in the south, most plants are evergreen and grow throughout the year. If leaves fall in the southern winter, it might be due to some specific reasons.

In winter, when roses enter a dormant period, their metabolic rate decreases. Overwatering at this time can easily cause waterlogging, leading to root rot and leaf shedding. Therefore, watering should be controlled, only keeping the potting soil slightly dry.

In winter, excessive fertilization can cause fertilizer damage, leading to root rot and leaf shedding. Therefore, fertilization should be moderate, with one application in winter and once or twice a week during the flowering season.

In winter, when the temperature is low and sunlight is insufficient, roses may shed leaves. Therefore, when overwintering indoors, attention should be paid to temperature and humidity, keeping the roses in a sunny, cool place with a temperature of around 5℃ and ensuring proper ventilation.

In winter, if diseases or pests such as tussock moths or aphids appear, they can damage the leaves or cause them to fall off. When this happens, you can spray with 50% fenvalerate emulsion 1000 times, 50% thiamethoxam emulsion 1000 times, or 50% malathion emulsion 1000 times.
Roses can be planted throughout the year, but they need to be protected from the cold in winter. In areas south of the North China, they can safely overwinter outdoors. The dormant period in winter is beneficial for blooming the following year; without dormancy, the blooming effect will be poor.
