1、 Cold resistant

It is a relatively cold resistant plant, which is also divided into varieties. Some varieties are very cold resistant and can withstand the low temperature environment of minus 20 degrees. Some have poor cold resistance and can only grow above 0 degrees. In order to ensure the normal winter, it is best to adjust the temperature to more than 0 degrees, so as to avoid frostbite of the plant

2、 Overwintering method

1. Potted plant: if the area is very cold, potted plant can be used. Before winter comes, move the flowerpot indoors in advance and put it in a place where the sun can shine, which can not only spend the winter safely, but also promote the robust growth of plants

2: Shelter: if you want to grow outside, but you are afraid of cold weather, you can use plastic film and foam board to cover up. It can play a role of warmth and will not cause frostbite. p>

3. Not only the temperature, but also the application of water should be controlled. If the basin soil contains a lot of water, it may suffer from the influence of cold climate at this time, which may cause frostbite at the root. Sufficient water can be poured in advance before the arrival of winter to improve the cold tolerance of plants
