Although it can withstand cold, it will not be frozen to death under normal conditions, and can normally survive in the natural environment. However, if the plant is in a low temperature environment for a long time, it will be unbearable and may be frozen to death. It is better to keep the temperature above 0 ℃, so that we can spend the winter safely. If planted outside, and the weather is relatively cold, you can use foam board to cover it up, so that it can help it through the winter. For particularly cold areas, to be on the safe side, you can use the form of potted plants, put them in the greenhouse in winter, or indoors, so as to ensure its safety.
1. In winter maintenance, it is also necessary to pay attention to the variety differences, because different varieties have different cold resistance, such as fireworks, Lyon village, etc., which are very strong, suitable for planting in the north.
2. In order to improve the cold resistance, we should also pay attention to water control, because under the condition of water accumulation, the roots are prone to frostbite, and water can be poured once before autumn, and water supply is suspended in winter.
3. More sunshine can increase the robustness of the plant and the overall temperature.
