In winter, low temperatures can cause the cactus to freeze, leading to the phenomenon of rotten roots. The indoor temperature in winter needs to be maintained at least above 5℃, and it should be placed on a balcony with sufficient light and long exposure to sunlight. You can also use a glass cover to cover it and use plastic film to cover the entire cactus plant at night to prevent cold and keep warm.
