Will roses freeze to death in winter?

The habits of roses

Roses have a strong tolerance to low temperatures. Generally speaking, as long as the winter temperature is not lower than -7℃, roses can survive the winter safely. To be more specific, roses in southern my country can be cultivated directly outdoors in winter and will not be frozen; in the north, if the roses are planted in the open field, there is no problem overwintering directly, but if they are potted roses, certain warming measures will be needed if they overwinter outdoors, while roses cultivated indoors do not require additional warmth. It should be noted that whether in the south or the north, rose seedlings need better cold-proof measures to maintain them in winter. The seedlings have relatively weak resistance and are easily frostbitten or even frozen to death.

Measures to protect against cold weather

Before the severe cold of winter comes, roses usually need to be pruned once. After pruning, the plants should be wrapped with thick cotton clothes, quilts and other materials. You can wrap them in several layers depending on the actual temperature, and then wrap them with a layer of plastic film on the outside, and then cover them with some hay or the like. It should be noted that if the roses are planted in the open field, it is necessary to cover the ground around the roots with several layers to prevent the soil from freezing and damaging the roots of the roses; if the roses are planted in pots, they must be wrapped and covered together with the pots to keep them warm.

Precautions

Although roses that overwinter indoors in the north do not have to worry about freezing to death, they are more likely to die, so special attention needs to be paid to indoor maintenance during the winter. There is heating in the north in winter, and many people move roses indoors to overwinter. However, the temperature indoors is relatively high, there is insufficient sunlight, and the amount of watering is too much, which can easily cause the roses to die. This is because roses will start to grow when the temperature is above 5℃, and the growth rate will accelerate when the temperature exceeds 13℃. However, the growth of roses requires sufficient sunlight to produce nutrients. If roses are kept in a growing state indoors in winter but lack sunlight, it can easily cause malnutrition or even death. Therefore, if you grow roses indoors in winter, you should pay attention to reducing watering, ensure sufficient sunlight, ventilate frequently, and maintain them properly.
