Habit of rose

Rose has strong tolerance to low temperature. Generally, as long as the temperature in winter is not lower than - 7 ℃, rose flowers can survive the winter safely. Specifically, roses in southern China can also be cultivated outdoors in winter without being damaged by freezing; In the north, if it is a rose planted in the open field, there is no problem to overwinter directly, but if it is a potted rose and overwinters in the open air, certain heat preservation measures need to be taken, while the rose cultivated indoors does not need additional heat preservation. It should be noted that whether in the South or the north, the seedlings of rose need better cold prevention measures for maintenance in winter. The resistance of seedlings is relatively weak, and they are easy to be frostbitten or even frozen to death

Cold proof measures

Before the arrival of severe cold in winter, it is generally necessary to prune the rose once. After pruning, wrap the plant with thick cotton clothes, quilts and other materials. According to the actual temperature, wrap it in several layers, and then wrap it with a layer of plastic film, and then cover it with some hay and so on. It should be noted that if it is a rose planted in the open field, it is necessary to cover the ground of the root with several layers to prevent the ground from being frozen through and damaging the root system of the rose; If it is a potted rose, it should be wrapped and covered together with the flower pot to keep warm

Precautions

Although the roses in the North overwintering indoors do not have to worry about being frozen to death, they are more likely to die. Special attention should be paid to indoor maintenance in winter. There is heating in winter in the north. Many people move roses indoors to survive the winter, but the temperature in the house is relatively high, the sunshine is insufficient, and the amount of watering is too much, which can easily lead to the death of roses. This is because the rose will begin to grow when the temperature is higher than 5 ℃, and the growth rate will accelerate when the temperature is higher than 13 ℃, but the growth of the rose needs enough sunlight to produce nutrients. In winter, the indoor rose keeps growing but lacks sunshine, which is easy to cause malnutrition and even death. Therefore, if you breed roses indoors in winter, you should pay attention to reducing watering, ensuring sufficient sunlight, ventilation and reasonable maintenance
