Although it is not easy to freeze to death, but also need to keep warm, not only for its winter is very beneficial, but also for its growth in the next year.
Relatively speaking, it is not afraid of cold, so it does not need to pay much attention to heat preservation. As long as the weather is relatively cold, it can be covered with a transparent plastic film, or straw can be used to keep warm. It should be noted that when spring comes, the covering will be removed. Some people will plant a small amount of plants in a large flowerpot. If they are raised at home, they can move the plants indoors, which also has a good warming effect.
