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.
